INTRODUCTION TO PSYCHIATRY
 Psychiatry is a medical specialty.
 It mostly deals with conditions in which the symptoms and signs
  predominantly related to emotions, perception, thinking or memory.
 It also encompasses learning disability and the psychological aspects of the
  rest of medicine.
 There are 2 primary characterizations of psychiatric disorders:
   Organic disorder: this is a form of decreased mental function due to
      medical or physical disease, rather than a psychiatric illness. Examples
      include dementia, and the results of encephalitis, meningitis, hypoxia,
      brain injury or chronic drug abuse and alcoholism.
   Functional disorder: this is a form of decreased mental function with no
      known organic basis but are believed to be the result of psychological
      factors such as emotional conflicts or stress. Examples include antisocial
      behaviors, phobias and personality disorders.
 The major diagnostic categories are:
   Psychoses (formerly called major mental illnesses): Schizophrenia.
   Neuroses (formerly called minor mental illnesses): anxiety disorders,
      dissociative disorders, somatoform disorders, eating disorders, and sexual
      dysfunction.
   Organic disorder: Dementia and Delirium.
   Mood disorders: Depression, Mania, and Bipolar disorder.
   Personality disorder.
   Substance misuse.
                                        3
FORMAL THOUGHT DISTURBACES
 Neologism- new word created by patient.
 Word salad- incoherent mixture of words and phrases.
 Incoherence- no logical or grammatical connection.
 Preservation- persisting response to a previous stimulus after a new stimulus
  has been presented.
 Verbigeration- meaningless repetition of words/phrases.
 Loosening of association- shift without logical relation.
 Blocking- abrupt interruption of train of thought.
DISTURBANCE OF THOUGHT CONTENT
 Delusion- false beliefs held by a patient that are not consistent with patient’s
  intelligence, social and cultural background and cannot be corrected by
  reasoning.
   Delusions of persecution- being harassed, cheated or persecuted
   Delusions of grandeur- exaggerated conception of importance, power or
      identity
   Delusions of reference- behavior of others refers to the patient
   Nihilistic delusions- self, others or the world is nonexistent
   Delusions of poverty- to be bereft of all material possessions
   Somatic delusions- involving functioning of the body
   Delusions of self-accusation- feeling of remorse and guilt
   Delusion of control- persons will, thoughts or feelings are being controlled
      by external forces (thought withdrawal, thought insertion, thought
      broadcasting, thought control)
   Delusion of infidelity (Othello syndrome)- delusion of infidelity of a
      spouse or partner. This affects males and less often females. It is
      characterized by recurrent accusations of infidelity, searches for evidence,
      repeated interrogation of the partner etc.
   Erotomania- delusional belief that a person is in love
CATATONIC SYMPTOMS
 Catatonic stupor- markedly slowed motor activity often to a point of
  immobility.
 Catatonic posturing- voluntary assumption of an inappropriate or bizarre
  posture.
 Echopraxia- pathological imitation of movements.
 Stereotypy- habitual involuntary movement
 Command automatism-automatic following of suggestions.

THE EGO, SUPEREGO AND ID
 According to Freud’s model of the psyche:
   The ID is the primitive and instinctual part of the mind that contains sexual
     and aggressive drives and hidden memories.
   The ego is the realistic part that mediates between the desires of the ID and
     the super-ego.
   The super-ego operates as a moral conscience.
 Freud’s single most enduring and important idea was that the human psyche
  (personality) has more than one aspect.
 Freud (1923) saw the psyche structured into 3 parts (i.e. tripartite), the ID, ego
  and superego, all developing at different stages in our lives.
 These are systems, not parts of the brain or in any way physical.
 Each part of the personality comprises unique features, the systems interact to
  form a whole. Each part of the whole makes a relative contribution to an
  individual’s behavior.
                                         6
 This form of process thinking has no comprehension of objective reality and
  is selfish and wishful in nature.
                                          7
THE SUPEREGO (OR ABOVE I)
 The superego incorporates the values and morals of society which are learned
  from one’s parents and others.
 It develops around the age of 3-5 during the phallic stage of psychosexual
  development.
 The superego’s function is to control the ID’s impulses, especially those which
  society forbids, such as sex and aggression.
 It also has the function of persuading the ego to turn to moralistic goals rather
  than simply realistic ones and to strive for perfection.
 The superego consists of 2 systems:
   The conscience: can punish the ego through causing feelings of guilt. For
      example, if the ego gives in to the ID’s demands, the superego may make
      the person feel bad through guilt.
   The ideal self (or ego-ideal): is an imaginary picture of how you ought to
      be, and represents career aspirations, how to treat other people, and how to
      behave as a member of society.
 Behavior which falls short of the ideal self may be punished by the superego
  through guilt.
 The super-ego can also reward us through the ideal self when we behave
  ‘properly’ by making us feel proud.
 If a person’s ideal self is too high a standard, then whatever the person does
  will represent failure.
 The ideal self and conscience are largely determined in childhood from
  parental vales and how you were brought up and either over- or under-indulges
  once he or she becomes an adult.
                                        8
FREUD’S STAGES OF PSYCHOSEXUAL
DEVELOPMENT
 Sigmund Freud (1856-1939) is probably the most well-known theorist when
  it comes to the development of personality.
 Freud’s stages of psychosexual development are, like other stage theories.
   They are completed in a predetermined sequence.
   They can result in either successful completion or a healthy personality.
   They can result in failure, leading to an unhealthy personality.
 This theory is probably the most well-known as well as the most controversial
  as Freud believed that we develop through stages based upon a particular
  erogenous zone.
 During each stage, an unsuccessful completion means that a child becomes
  fixated on that particular erogenous.
 To remember the stages of psychosexual development, use the mnemonic:
   Old= Oral stage (birth to 18 months)
   Aged= Anal stage (18 months to 3 years)
   Parents= Phalic stage (3 to 6 years)
   Love= Latent stage (6 to 12 years i.e. puberty)
   Grapes= Genital stage (12 years onwards)
ORAL STAGE (BIRTH TO 18 MONTHS)
 During the oral stage, the child is focused on oral pleasures (sucking).
 Too much or too little gratification can result in an oral fixation or oral
  personality which is evidenced by a preoccupation with oral activities.
 This type of personality may have a stronger tendency to smoke, drink alcohol,
  over eat or bite his or her nails.
 Personality wise, these individuals may become overly dependent upon
  others, gullible (easily deceived or cheated) and perpetual followers.
 On the other hand, they may also fight these urges and develop pessimism and
  aggression toward others.
ANAL STAGE (18 MONTHS TO 3 YEARS)
 The child’s focus of pleasure in this stage is on eliminating and retaining feces.
 Through society’s pressure, mainly via parents, the child has to learn to control
  anal stimulation.
 In terms of personality, after effects of an anal fixation during this stage can
  result in an obsession with cleanliness, perfection and control (anal retentive).
 On the opposite end the spectrum, they may become messy and disorganized
  (anal expulsive).
                                         9
PHALLIC STAGE (3 YEARS TO 6 YEARS)
 The pleasure zone switches to the genitals.
 Freud believed that during this stage the boy develops unconscious sexual
  desires for their mother.
 Because of this he becomes rivals with his father and sees him as competition
  for the mother’s affection.
 During this time, boys also develop a fear that their father will punish them
  for these feelings, such as by castrating them.
 This group of feelings is known as Oedipus complex (after the Greek
  Mythology figure who accidentally killed his father and married his mother).
 Later it was added that girls go through a similar situation, developing
  unconscious sexual attraction to their father.
 Although Freud strongly disagreed with this, it has been termed the Electra
  complex by more recent psychoanalysts.
 According to Freud, out of fear of castration and due to the strong competition
  of his father, boys eventually decide to identify with him rather than fight him.
 By identifying with his father, the boy develops masculine characteristics and
  identifies himself as a male, and represses his sexual feelings toward his
  mother.
 A fixation at this stage could result in sexual deviancies (both overindulging
  and avoidance) and weak or confused sexual identity according to
  psychoanalysts.
LATENCY STAGE (6 YEARS TO PUBERTY)
 It’s during this stage that sexual urges remain repressed.
 Children interact and play mostly with same sex peers.
GENITAL STAGE (PUBERTY ON)
 The final stage of psychosexual development begins at the start of puberty
  when sexual urges are once again awakened.
 Through the lessons learned during the previous stages, adolescents direct
  their sexual urges onto opposite sex peers.
 It is understood that the primary focus of pleasure is the genitals.

PSYCHOTIC DISORDERS
 Psychosis is a condition where an individual is detached from reality.
 It denotes a disturbance in sense of reality e.g. beliefs that are not true and
  seeing/hearing things that are not there.
 Individuals with psychosis often find it difficult to differentiate what is real
  from what is unreal.
 Psychosis is characterized by:
   Delusions: strong false beliefs held by a person that are not consistent with
      their intelligence, social and cultural background and cannot be easily
      corrected by reasoning. They include:
         o Delusions of reference: certain events that happen relate directly to
             the patient
         o Delusion of grandiose: person has a unique sense of significance
         o Paranoid delusions: belief they are being harmed or watched. This
             can lead to patients avoiding their medication due to paranoid
             delusions about the medication
         o Delusions of control: thoughts and actions are being controlled.
         o Erotomania: delusion that someone is in love with them.
   Hallucination: false perception of stimulus that does not exist. They
      include:
         o Auditory hallucinations (most common)
         o Visual hallucinations (common)
         o Tactile hallucinations
         o Olfactory hallucinations
         o Gustatory hallucinations
         o Visceral hallucinations
   Disorganized behavior: can be directly observed
   Disorganized thinking: can be indirectly observed i.e. through speech
      patterns e.g.
         o Poverty of content/speech (Alogia)
         o Tangential speech- getting off topic
         o Thought blocking
         o Word salad
         o Preservation- words and ideas repeated even after topic has been
             switched
   Agitation and aggression: Anxiety, heightened emotions, heightened motor
      activity.
                                       12
 Underlying causes include:
   Psychiatric conditions e.g. schizophrenia
   Medical conditions e.g. delirium
   Substance abuse e.g. alcohol and hallucinogens (e.g. LSD)
   Medication e.g. antiparkinson drugs (levo-dopa) and antivirals
                                     13
SCHIZOPHRENIA
 Schizophrenia (Splitting of the mind) is a psychosis, typically presenting in
  young adults (16 to 25 years) affecting 1% of the population.
   Even though schizophrenia can be interpreted to mean splitting of the
      mind, it does not refer to a split personality. It rather refers to a scattered
      or fragmented pattern of thinking.
 It is distinguished from other psychoses by:
   The presence of specific types of delusions, hallucinations and thought
      disorder.
   The primary disorder, which is not one of affective (mood) or organic
      etiology.
   The clinical course.
 Schizophrenia is characterized by:
   A collection of abnormalities in thinking, behavior and emotion.
   A group of characteristic positive and negative symptoms (it is a
      syndrome)
   Deterioration in social, occupational or interpersonal relationships.
   Continuous signs of the disturbance for at least 6 months.
 There is no single symptom that is pathognomonic and there is a wide
  variation in clinical presentation.
 Schizophrenia is prevalent across racial, sociocultural and national
  boundaries, with a few exceptions in the prevalence rates in some isolated
  communities.
 Men and women are equally affected but have different presentations and
  outcomes:
   Men tend to present in early to mid-20s
   Women present in late 20s
   Men tend to have more negative symptoms and poorer outcome compared
      to women.
   Some studies suggest this could be due to estrogen regulation of dopamine.
 Schizophrenia rarely presents before age 15 or after age 55.
 There is strong genetic predisposition:
   50% concordance rate among monozygotic twins
   40% risk of inheritance if both parents have schizophrenia
   12% risk if one first-degree relative is affected
 Substance use is comorbid in many patients with schizophrenia. The most
  commonly abused substance is nicotine (>50%), followed by alcohol,
  cannabis and cocaine.
                                         14
 Post-psychotic depression is the phenomenon of schizophrenic patients
  developing a major depressive episode after resolution of their psychotic
  symptoms.
HISTORY
 Emil Kraeplin: recognized that this illness develops relatively early in life and
  its course is likely deteriorating and chronic but was not followed by any
  organic changes of the brain, detectable at that time. He therefore called it
  ‘Dementia praecox’ (Dementia: deterioration; praecox: early onset). He
  recognized the characteristic features of dementia praecox such as delusions,
  hallucinations, disturbances of affect and motor disturbances.
 Eugen Bleuler (1911): renamed dementia praecox as schizophrenia (splitting
  of the mind). He recognized the cognitive impairment in this illness. Bleuler
  described the characteristic symptoms which were then thought to be
  diagnostic of schizophrenia, these included (4As of Bleuler):
      o Affective blunting/disturbance: disturbances of affect such as
         inappropriate affect
      o Association disturbances: loosening of association, thought disorder,
         fragmented thinking
      o Autism: withdrawal from reality
      o Ambivalence: marked inability to decide for or against (fragmented
         emotional response)
  According to Bleuler, these groups of symptoms are “primary” for the
  diagnosis of schizophrenia. The other known symptoms of schizophrenia
  include hallucinations, delusions which appeared in schizophrenia very often.
  He called them as “secondary symptoms”, because they could be seen in any
  other psychotic disease, which are caused by quite different factors- from
  intoxication to infection or other disease entities.
 Kurt Schneider: Emphasized the role of psychotic symptoms, as
  hallucinations, delusions and gave them the privilege of “first rank symptoms”
  even in the concept of the diagnosis of schizophrenia. First rank symptoms
  include:
   Delusions:
         o Delusion of perception
         o Delusion of control
         o Delusion of influence and passivity (passivity of thought, feelings or
            actions)
                                        15
    Hallucinations
        o Third person auditory hallucinations
        o Voices commenting on one’s action
        o Running commentary (voices commenting or discussion the patient
           in the third person)
    Disorders of thought process and content
        o Thought echo (voices speaking out thoughts aloud)/ Echo delapance.
        o Thought withdrawal: thoughts cease and subject experiences them
           as removed by an external force.
        o Thought insertion: experience of thoughts imposed by some external
           force on person’s passive mind.
        o Thought broadcasting/ diffusion: experience of thoughts escaping
           the confines of self and as being experienced by others around.
CLINICAL FEATURES
 In general, the symptoms of schizophrenia are broken up into 3 categories:
   Positive symptoms:
     o Hallucinations: Auditory hallucination- in third person, visual
        hallucinations.
     o Delusions of control- an outside force is controlling their actions and of
        reference- they think insignificant remarks are directed at them like a
        news caster speaking directly to them through the TV
     o Disorganized/Bizarre behavior (silly behavior) e.g. wearing multiple
        layers of jackets on a hot day
     o Disorganized speech: word salad
     o Positive formal thought disorder: autistic thinking, loosening of
        association, incoherence of speech, thought block, thought withdrawal,
        thought insertion, thought broadcasting, neologisms and word salad.
     o Catatonic behavior: either by resistance to movement or stupor.
     o These tend to respond more robustly to antipsychotic medications.
   Negative symptoms:
     o Flat or blunted affect,
     o Anhedonia (inability to experience pleasure),
     o Alogia (Poverty of speech- lack of content in speech),
     o Avolition/Apathy (decreased motivation) and lack of interest in
        socialization.
     o These symptoms are comparatively more often treatment resistant and
        contribute significantly to the social isolation of schizophrenic patients
                                       16
    Cognitive symptoms:
     o Impairments in attention, executive function and working memory.
       These symptoms may lead to poor work and school performance. They
       are often subtle and difficult to notice.
                                      17
 The theorized dopamine pathways affected in schizophrenia include:
   Mesolimbic: Excessive dopaminaergic activity responsible for positive
     symptoms.
   Prefrontal cortical: inadequate dopaminergic activity responsible for
     negative symptoms.
 Other important dopamine pathways affected by antipsychotics:
   Tuberoinfundibular:         blocked      by     antipsychotics       causing
     hyperprolactinemia which may lead to gynecomastia, galactorrhea, sexual
     dysfunction and menstrual irregularities.
   Nigrostriatal:        Blocked        by       antipsychotics,        causing
     Parkinsonism/extrapyramidal side effects such as tremor, rigidity, slurred
     speech, akathisia (unpleasant, subjective sense of restlessness and need to
     move often manifested by the inability to sit still), dystonia and other
     abnormal movements.
 Other neurotransmitter abnormalities implicated in schizophrenia include:
   Elevated serotonin: some of the second-generation (atypical)
     antipsychotics (e.g. risperidone and clozapine) antagonize serotonin and
     weakly antagonize dopamine.
   Elevated norepinephrine: long-term use of antipsychotics has been shown
     to decrease activity of noradrenergic neurons.
   Decreased gamma-aminobutyric acid (GABA): there is a decrease in
     expression of the enzyme necessary to create GABA in the hippocampus
     of schizophrenic patients.
   Decreased levels of glutamate receptors: schizophrenic patients have fewer
     NMDA receptors. This corresponds to the psychotic symptoms observed
     with NMDA antagonists like ketamine.
DIAGNOSIS
 For the diagnosis of schizophrenia, it is necessary for either:
   Presence of one very clear symptom- from (a) to (d) for one month or more
   Presence of at least 2 symptoms - from point (e) to (h) for one month or
     more
 Symptoms include
  a. The hearing of own thoughts, the feelings of thought withdrawal, thought
     insertion or thought broadcasting
  b. The delusions of control, outside manipulation and influence, or the feeling
     of passivity which are connected with the movements of the body or
     extremities, specific thoughts, acting or feelings, delusional perception
                                       18
  c. Hallucinated voices, which are commenting pertaining the behavior of the
     patient or they talk about him between themselves or the other types of
     hallucinatory voices, coming from different parts of the body.
  d. Permanent delusions of different kind, which are inappropriate and
     unacceptable in the given culture
  e. The lasting hallucination of every form
  f. Blocks or intrusion of thoughts into the flow of thinking and resulting
     incoherence and irrelevance of speech or neologisms
  g. Catatonic behavior
  h. Negative symptoms, for instance the expressed apathy, poor speech,
     blunting and inappropriateness of emotional reactions
  i. Expressed and conspicuous qualitative changes in patient’s behavior, the
     loss of interests, hobbies, aimlessness, inactivity, loss of relations to others
     and social withdrawal.
 According to DSM-IV on diagnosis of schizophrenia is that symptoms of
  schizophrenia should last 6 consecutive months (with at least 1 month of the
  active phase). If symptoms are present between 1-6 month a diagnosis of
  schizophreniform is made.
 70% of patients with schizophreniform are later diagnosed to have
  schizophrenia.
CLINICAL SUBTYPES
PARANOID SCHIZOPHRENIA (F20.0)
 Characterized mainly by delusions of persecution, feelings of passive or active
  control, feeling of intrusion and often by megalomanic tendencies also.
 The delusions are not usually systemized too much, without tight logical
  connections and are often combined with hallucinations of different senses,
  mostly with hearing voices.
 Disturbances of affect, volition and speech and catatonic symptoms are either
  absent or relatively inconspicuous.
HEBEPHRENIC/ DISORGANIZED SCHIZOPHRENIA (F20.1)
 It is characterized by disorganized thinking with blunted and inappropriate
  emotions.
 It begins mostly in adolescent age; the behavior is often bizarre. There could
  appear mannerisms, grimacing, inappropriate laugh and joking,
  pseudophilosophilcal brooding and sudden impulsive reactions without
  external stimulation.
 Usually the prognosis is poor because of the rapid development of negative
  symptoms, particularly flattening of affect and loss of volition.
                                         19
 Hebephrenia should normally be diagnosed only in adolescents or young
  adults.
CATANTONIC SCHIZOPHRENIA (F20.2)
 It is characterized mainly by motoric activity which might be strongly
  increased (hyperkinesis) or decreased (stupor) or automatic obedience and
  negativism.
 We recognize two forms:
   Productive form: which show catatonic excitement, extreme and often
     aggressive activity. Treatment by neuroleptics or by electroconvulsive
     therapy
   Stuporose form: characterized by general inhibition of patient’s behavior
     or at least by retardation and slowness, followed often by mutism,
     negativism, flexibilitas cerea or by stupor. The consciousness is not absent.
UNDIFFERENTIATED SCHIZOPHRENIA (F20.3)
 Psychotic conditions meeting the general diagnostic criteria for schizophrenia
  but not conforming to any of the subtypes in F20.0 – F20.2 or exhibiting the
  features of more than one of them without a clear predominance of a particular
  set of diagnostic characteristics.
 This subgroup represents also the former diagnosis of atypical schizophrenia.
                                          20
OTHER CONSIDERATIONS
POSTSCHIZOPHRNIC DEPRESSION (F20.4)
 A depressive episode, which may be prolonged, arising in the aftermath of a
  schizophrenic illness.
 Some schizophrenic symptoms either positive or negative must still be present
  but they no longer dominate the clinical picture.
 These depressive states are associated with an increased risk of suicide.
RESIDUAL SCHIZOPHRENIA (F20.5)
 A Chronic stage in the development of schizophrenia with clear succession
  from the initial stage with one or more episodes characterized by general
  criteria of schizophrenia to the late stage with long-lasting negative symptoms
  and deterioration (not necessarily irreversible).
SIMPLE SCHIZOPHRENIA (F20.6)
 Simple schizophrenia is characterized by early and slowly developing initial
  stage with growing social isolation, withdrawal, small activity, passivity,
  avolition and dependence on the others.
 The patients are indifferent, without any initiative and volition. There is not
  expressed the presence of hallucinations and delusions.
PERSISTENT DELUSIONAL DISORDERS (F22)
 Includes a variety of disorders in which long-standing delusions constitute the
  only, or the most conspicuous, clinical characteristic and which cannot be
  classified as organic, schizophrenic or affective.
 Their origin is probably heterogenous but it seems that there is some relation
  to schizophrenia.
DELUSIONAL DISORDER (F22.0)
 A disorder characterized by the development of one delusion or of the group
  of similar related delusions, which are persisting unusually long, very often
  for the whole life.
 Other psychopathological symptoms- hallucinations, intrusion of thoughts etc.
  are not present and are excluding this diagnosis.
 It begins usually in the middle age.
                                       21
ACUTE AND TRANSIENT PSYCHOTIC DISORDERS
 The criteria should be the following features:
   Acute beginning (to two weeks)
   Presence of typical symptoms (quickly changing “polymorphic
     symptoms”)
   Presence of typical schizophrenic symptoms
 Complete recovery usually occurs within a few months often within a few
  weeks or even days.
 The disorder may or may not be associated with acute stress, defined as
  usually stressful events preceding the onset by one to two weeks.
INVESTIGATIONS
 Assessment includes
   Full history (objective/collateral and subjective)
   Mental state examination
   Neurological examination
 Investigate differentials (causes) if indicated:
 Blood investigations:
     o Endocrine: Thyroid function test (hyper/hypothyroidism), Cortisol
        (Addison/Cushing disease)
     o Calcium (Hyper/hypocalcemia)
     o Syphilis & serology
     o Supportive: FBC, U&E and LFTs (for management of drugs mostly)
 Urine drug screen: to rule out substance induced psychosis from intoxication
  or withdrawal (some implicated drugs antiparkisonian agents,
  anticonvulsants,      antihistamines,       antimicrobials, anticholinergics,
  antihypertensives, NSAIDs, alcohol, cocaine, hallucinogens- [LSD, Ecstasy],
  Cannabis, Benzodiazepines, barbiturates, PCP, inhalants)
 Imaging:
     o MRI/CT: to rule out CNS disease (multiple sclerosis, Tumors/space
        occupying lesions), cerebrovascular disease, Alzheimer’s disease,
        Parkinson’s disease, encephalitis, prion disease.
     o EEG: epilepsy (often temporal lobe)
                                      22
TREATMENT
 Non-pharmacological therapy: Psychotherapy/talk therapy
    o Cognitive behavioral therapy: 16 sessions, focusing on re-evaluating
       abnormal thoughts and perceptions and reducing the distress resulting
       symptom.
    o Family therapy: at least 10 sessions over 3-12 months
           Psychoeducation: e.g. how to respond to patient’s delusions,
            advice on crisis management and emphasizing the importance of
            creating low stress environments at home.
           ART therapy: is another option. It can help with self-expression
            and is delivered in grouped thus alleviating social isolation.
 Pharmacological therapy:
     o 1st line: 1st generation or 2nd generation antipsychotic (D2 antagonist)
            1st generation (typical):
                    Chlorpromazine initially 25 mg 3 times a day orally, adjust
                       according to response, alternatively 75mg once daily,
                       adjusted according to response, dose to be taken at night,
                       maintenance 75-300mg daily, increased if necessary up to
                       1g daily, this dose may be required in psychoses.
                    25-50mg every 6-8 hours IM for acute psychoses
            2 generation (atypical): Clozapine
                nd
                    12.5 mg 1-2 times a day for day 1, then 25-50mg for day
                       2, then increased if tolerated in steps of 25-50 mg daily
                       dose to be increased gradually over 14-21 days, increased
                       to up to 300mg daily in divided doses, larger dose to taken
                       at night, up to 200mg daily may be taken as a single dose
                       at bedtime, increased in steps of 50-100mg 1-2 times a
                       week if required, it is preferable to increase once a week,
                       usual dose 200-450 mg daily, max 900mg per day, if
                       restarting after interval of more than 48 hours, 12.5mg
                       once or twice on first day (but may be feasible to increase
                       more quickly than on initiation)- extreme caution if
                       previous respiratory or cardiac arrest with initial dosing.
     o 2 line: Clozapine. Offer if 2 different antipsychotics were ineffective
        nd
     o Start low and titrate up, then observe effectiveness for 4-6 weeks at
       optimum dose.
                                       23
 The acute psychotic schizophrenic patients will respond usually to
  antipsychotic medication.
 According to current consensus we use the first line therapy the newer atypical
  antipsychotics, because their use is not complicated by appearance of
  extrapyramidal side-effects or these are much lower than with classical
  antipsychotics.
                                       24
 During course of treatment, monitor:
   Weight: weekly for first 6 weeks, then at 3 months.
   Blood parameters such as full blood count and blood glucose at 3 months
      as well as prolactin levels at 6 months.
   Electrocardiograph monitoring if haloperidol or pimozide are used.
 Note: if health deteriorates treatment should be further titrated and continued
  in hospital.
                                       25
HIV PSYCHOSIS
 HIV is the most common infectious agent known to cause cognitive
  impairment.
 Psychosis is one manifestation of HIV-associated dementia.
 It tends to be more common in people who have a history of prior psychiatric
  disorder or drug abuse (especially amphetamines and other stimulants).
 Psychosis is sometimes also a sign of very advanced AIDS, and patients
  should seek treatment immediately.
 Psychosis is a generic term for any one of a number of symptomatic
  manifestations of thought disorders.
 Psychotic symptoms can be part of a severe major depressive syndrome,
  schizophrenia, mania in bipolar disorder, or extremes of obsessive-compulsive
  disorder.
 Some of the symptoms of psychotic episode include: Hallucinations,
  Delusions, Paranoia, Mania and Depression.
 Depression and HIV can cause:
   Loss of sexual desire and function
   Lack of appetite
   Headache
   Insomnia
   Fatigue
   Upset stomach
   Diarrhea
   Restlessness or anxiety
CLINICAL FEATURES
 Acute HIV symptoms are similar to those of other viral infections. They
  include: Tiredness, Headache, Weight loss, Frequent fever, Sweats, Lymph
  node enlargement, and Rash
 HIV-associated neurocognitive disorder:
   Clinical experience and research provide substantial evidence that HIV
     directly infects the brain soon after initial infection.
   It can result in organic disease expression such as central nervous system
     impairment, dementia, pain and mood disorders.
 Clinical manifestation varies depending on the part(s) of the brain affected.
 Decline may be observed in executive functioning, attention, working
  memory and psychomotor activity.
 Psychiatric and neuromotor symptoms may also be present.
                                      26
PSYCHIATRIC ILLNESS AND HIV/AIDS
 There is a strong link between mental illness and HIV/AIDS.
 50% or more of patients with HIV/AIDS have a comorbid psychiatric
  disorder.
 The prevalence of mental illness in patients with HIV/AIDS is reported to be
  8 times higher than in those without HIV/AIDS.
 Depression, bipolar disorder, anxiety disorders, delirium, substance abuse and
  schizophrenia have all been identified in persons receiving highly active
  antiretroviral therapy (HAART).
 Patients with HIV/AIDS and psychiatric illness have a decreased quality of
  life, poor adherence to medications, faster disease progression and increased
  mortality.
DIAGNOSIS
 Patients whose diagnoses is schizophrenia, schizoaffective disorder, and
  bipolar disorder are at greater risk for HIV infection.
 Patients with HIV/AIDS with primary psychosis may have poor medication
  adherence rates due to illness-related confusion or paranoia about
  medications.
 Furthermore, they may lack the resources to manage the complications and
  stress related to living with HIV/AIDS.
 New onset/secondary psychosis has been reported in individuals with late-
  stage HIV/AIDS with CD4 counts <200 who have not been diagnosed with a
  psychotic disorder previously.
 These patients may experience more persecutory and grandiose delusions
  rather than hallucinations.
 Neuropsychiatric symptoms in patients with HIV/AIDS may be due to the
  presence of HIV or other infections in the CNS, tumors, or other inflammatory
  illnesses.
 Medications that have been implicated in neuropsychiatric symptoms include
  Efavirenz, rilpivirine, and other HAART regimens, interferon,
  metoclopramide, corticosteroids, muscle relaxants and clonidine.
 It is possible that symptoms may continue even after medications are
  discontinued, has been reported in individuals with late-stage HIV/AIDS with
  CD4 counts <200 who have not been diagnosed with a psychotic disorder
  previously. These patients may experience more persecutory and grandiose
  delusions rather than hallucinations.
                                      27
TREATMENT AND EFFECTS
 Antipsychotics (typical antipsychotics e.g. haloperidol, chlorpromazine)
  remain the treatment of choice for psychosis in HIV/AIDS, regardless of the
  cause of the symptoms.
   Chlorpromazine initially 25 mg 3 times a day orally, adjust according to
      response, alternatively 75mg once daily, adjusted according to response,
      dose to be taken at night, maintenance 75-300mg daily, increased if
      necessary up to 1g daily, this dose may be required in psychoses.
   25-50mg every 6-8 hours IM for acute psychoses.
 Antipsychotics are usually effective in relieving symptoms of psychosis in the
  short term.
 The long-term use of antipsychotics is associated with adverse effects such as
  involuntary movement disorders, gynecomastia (swelling of the breast tissue
  in boys or men), impotence, weight gain and metabolic syndrome.
 First generation antipsychotics (typical antipsychotics) are used.
 Many factors must be taken into consideration when choosing an
  antipsychotic medication.
 Worthy of note are Drug-drug interactions (DDIs), adverse effect profiles,
  patient history of antipsychotic use, cost, and patient preference.
 Psychostimulants target fatigue, apathy and psychomotor retardation.
 Tricyclics have more side effects than the selective serotonin reuptake
  inhibitors (SSRIs).
 SSRIs are the most commonly prescribed antidepressants.
   Sertraline initially 50mg daily, then increased in steps of 50mg at intervals
      of at least 1 week if required, maintenance 50mg daily, maximum 200mg
      per day.
   They can ease symptoms of moderate to severe depression
   Relatively safe and typically cause fewer side effects than other types of
      antidepressants do.
   SSRIs ease depression by increasing levels of serotonin in the brain.
      o Serotonin is often referred to as the “feel good hormone”.
      o It carries messages between brain cells and contributes to well-being,
         good mood, appetite, social behavior. It as well helps to regulate the
         body’s sleep-wake cycle and the internal clock.
   They can also cause sedation, constipation
                                       28
COMPLICATIONS
 Self-harm also known as self-injury is defined as the intentional, direct
  injuring of body tissue done without suicidal intentions.
 Other terms such as cutting and self-mutilation have been used for any self-
  harming behavior regardless of suicidal intent.
 If left untreated:
   Psychiatric illness in patients with HIV/AIDS may lead to further
      transmission of HIV
   Psychiatric illness in patient with HIV/AIDS patients will engage in high
      risk behaviors
   Psychiatric illness in patients with HIV/AIDS will deteriorate and lead to
      poor adherence to HAART.
                                     29
DEMENTIA,       DELIRIUM                                                AND
NEUROPSYCHIATRY
 Psychiatric disorders labelled ‘organic’ are those with demonstrable pathology
  or etiology or that arise directly from a medical disorder.
 The major organic disorders are dementia and delirium.
DEMENTIA
 Dementia typically refers to a gradual decline of mental functioning,
  characterized by memory problems and personality and behavioral changes.
 Dementia is commoner in women.
 Dementia is most common beyond the age of 65 years.
 Types of dementia include:
   Alzheimer’s disease (most common-80%)
   Vascular dementia
   Lewy body dementia
   Frontotemporal dementia
   Mixed
ALZHEIMER’S DISEASE
 This is the most common cause of dementia (60-80%)
 It is neurodegenerative disorder due to brain amyloidosis (which form
  plaques-abnormal protein fragments between neurons) and Tau pathology
  (Tau proteins are abnormally accumulated in neuron cells as tangles):
   Mis-cleavage of the amyloid precursor protein by beta and gamma
      secretase instead of the usual alpha-secretase leading to the formation of
      beta-amyloid (also known as A).
   Adeposits in the extracellular space and aggregates as senile plaques,
      occupying up 20 % of the brain but potentially leading to lower levels in
      the CSF.
   Also involves neurofibrillary tangles of Tau proteins in both the intra- and
      extra-cellular spaces.
 The pattern of presentation is insidious in onset. There is progressive and
  global cognitive deterioration.
 It is characterized by the 4A:
   Amnesia: recall is impaired first, with recognition initially intact. Short-
      term affected before long-term, with difficulty learning new things.
   Aphasia: expressive first, with word-finding difficulties is common.
   Agnosia: e.g. difficulty naming object in hand with eyes closed. Also
      anosognosia (poor insight)
                                      30
   Apraxia: impaired motor planning skills e.g. dressing apraxia.
 Individuals also have visuospatial problems (easily get lost), affective and
  psychotic symptoms and reduced executive function, apathy.
 Risk factors for Alzheimer’s:
   Age: increase with age (65-80 years)
   Family history
   Specific mutations: Apolipoprotein E-E4 (ApoE e4), CL1, CLU, PICALM
   Down’s syndrome
   Vascular risk factors
   Limited intellectual activity or stimulation
   Depression
   Traumatic brain injury, especially if later in life
VASCULAR DEMENTIA
 Due to cumulative effects of many small strokes.
 Can co-occur with Alzheimer’s but rarely with Lewy body dementia.
 Presentation is stepwise, with rapid decline in specific functions. However,
  may fluctuate with partial recovery.
 There may be focal neurological signs.
 Relatively preserved personality and insight.
 Risk factors for vascular dementia:
   Ischemic heart disease and its risk factors
   Diabetes
LEWY BODY DEMENTIA
 Characterized by aggregations of Lewy bodies in substantia nigra and other
  brain structures.
 Lewy bodies consist of alpha synuclein, ubiquitin and other proteins.
 It is characterized by fluctuating changes in cognition. Changes can be day to
  day and cycles get progressively shorter (e.g. hours). Lucid periods may be
  very distressing due to insight, leading to depression.
 Visual hallucinations: vivid and often frightening. May include children,
  animals or Lilliputian hallucinations. No auditory hallucinations, so figures
  don’t speak back.
 Parkinsonism including falls.
 There may also be REM sleep disorder.
                                      31
FRONTOTEMPORAL DEMENTIA
 Frontotemporal dementia/ Pick’s disease/Frontal lobe dementia is
  Characterized by atrophy of the frontal and temporal lobes.
 3 pathological subtypes based on the types of abnormal protein deposition:
   FTD: Fused in sarcoma (FUS) protein
   Phosphorylated Tau
   Transactive response DNA-binding protein 43 (TDP43)
 Frontotemporal dementia may be part of motor neuron disease.
 It usually has a younger onset (45-70)
 20% have autosomal dominant inheritance.
 Relative to Alzheimer’s more personality and speech problems early on with
  episodic and topographical memory retained until quite late.
 3 main clinical syndromes:
   Behavioral variant FTD: impaired interpersonal and executive skills
      including apathy, disinhibition, obsessions and stereotypies.
   Primary progressive aphasia which has 2 subtypes:
      o Progressive non fluent aphasia: involving poor speech production and
      o Semantic aphasia involving difficulty understanding and remembering
         words and their meanings.
MANAGEMENT
 Management is multidisciplinary. Refer to specialist clinic for diagnosis. This
  involves:
   Bloods and imaging
   Formal cognitive assessment e.g. with Addenbrooke’s Cognitive
     Examination-Revised (ACE-R). Scores <45 suggest cognitive impairment.
   Detailed history from the patient and a collateral history
 Investigations to rule out other causes
   Blood: FBC, U&E, LFTs, Calcium, Thyroid function tests, Vitamin B12
     serum assay, folate, ferritin and ceruloplasmin.
   Urine dip for UTI, especially in an acute context
   Tissue diagnosis:
     o CSF tau and beta-amyloid testing can support diagnosis of Alzheimer’s
        if unclear clinically.
     o A definitive pathological diagnosis can only be made post-mortem but
        is rarely necessary
   Imaging
     o CT head:
            To look for vascular disease and rule out space occupying lesions.
                                       32
            Small vascular changes are common but need to be significant to
              support diagnosis of vascular dementia.
            Alzheimer’s may show mesial temporal lobe atrophy.
            MRI if vascular dementia is suspected.
 Medical management:
   Oral cholinesterase inhibitors are the first line treatment for mild to
     moderate Alzheimer’s
     o Drugs: Donepezil, galantamine or rivastigmine (also available as a
        patch)
     o Can be used in LBD but not in vascular dementia or FTD.
     o Side effects: diarrhea and vomiting, cramps, urinary incontinence,
        headache, dizziness, insomnia, exacerbate peptic ulcer disease,
        bradycardia and AV block.
     o Note:
            ECG is done first, as 2nd degree heart block is a contraindication.
            Check pulse after starting for bradycardia
            Take after eating due to GI side effects
            Can switch to rivastigmine patch if GI side effects especially bad.
   Memantine is a glutamate receptor antagonist used in:
     o Severe Alzheimer’s
     o Moderate Alzheimer’s or LBD where cholinesterase inhibitors are not
        tolerated or are ineffective (having tried 2).
 Other options for behavioral and psychological symptoms:
   First optimize non-pharmacological methods and rule out underlying
     causes of distress e.g. pain.
   Antipsychotics at lowest dose and duration possible only if risk to self or
     others or experiencing distressing hallucinations or delusions.
   Antidepressants only in severe depression.
PROGNOSIS
 Patients with Alzheimer’s and LBD usually die within 7 years of diagnosis.
  Sooner in vascular dementia.
DIFFERENTIAL DIAGNOSIS
 Reversible dementias:
   Hypothyroidism
   Electrolyte abnormalities
   Decreased Vitamin B2
   Anemia
                                      33
     Normal pressure hydrocephalus. Classic triad of dementia, urinary
        incontinence and gait ataxia
   Non-reversible dementias:
     Cruetzfeldt-Jakob’s disease (mad cow disease): a disease of the nervous
        system caused by slow-acting prion which eventually affect the brain.
     Hungtington’s
   Delirium: an acutely altered cognitive state which should resolve with
    treatment of the underlying cause. May co-exist with dementia.
   Depression:
     In the elderly, often features pseudodementia i.e. subjective memory loss
     Unlike Alzheimer’s, cognitive impairment will be patchy and not global.
     Worse in the morning, while Alzheimer’s is worse in the evening.
   Mild cognitive impairment
     Mild memory loss but no functional impairment
     50% progress to dementia in 5 years, while the remainder are stable,
        improve or have a non-dementia pathology.
                                      34
DELIRIUM
 Delirium is a medical emergency. It may be the only early manifestation of
  serious illness.
   Think of delirium as acute brain failure- a medical emergency like other
     acute organ failures.
   Terms commonly used for delirium include toxic or metabolic
     encephalopathy, acute organic brain syndrome, acute confusional state,
     acute psychosis, and ICU
     psychosis.
 It is reversible but can
  potentially advance to coma,
  seizures or death.
 Delirium         often      goes
  unrecognized.
 Almost any medical condition
  can cause delirium. Delirium
  can also be caused by
  pharmacological drugs e.g.
  drugs with anticholinergic
  effects      (e.g.      tricyclic
  antidepressants) or sedatives.
 The        most        common
  precipitants of delirium in
  children are febrile illnesses
  and medications.
 Delirium is however much
  more common in older
  individuals than younger ones.
                                    35
 Risk factors:
   Polypharmacy, including the use of psychotropic medications (especially
     benzodiazepines and anticholinergic drugs)
   Advanced age
   Male gender
   Alcohol use (delirium tremens)
   Preexisting cognitive impairment or depression
   Prior history of delirium
   Severe or terminal illnesses
   Multiple medical comorbidities (dementia, constipation, pneumonia,
     urinary tract infection)
   Impaired mobility
   Hearing or vision impairment
   Malnutrition
   Pain
                                    36
Figure 2: The cause of delirium is unknown but theories suggest that (1) there is a disturbance in the
overall level of the neurotransmitters acetylcholine, dopamine, norepinephrine and glutamate, (2) a
    problem in neuron action potential transmission (3) production of cytokines as a result of an
                                        inflammatory process.
CLINICAL FEATURES
 Primarily a disorder of attention and awareness (i.e. orientation in time, place
  and person-disorientation).
 Cognitive deficits develop acutely over hours to days.
 Symptoms fluctuate throughout the course of a day, typically worsening at
  night.
 Other features include deficits in recent memory, concentration, language
  abnormalities, incoherent speech, perceptual disturbances (usually visual such
  as illusions or hallucinations), transient persecutory delusions, irritability and
  agitation or somnolence and decreased activity (sluggish & drowsy, less
  reactive & sullen as well as looking withdrawn).
 Circadian rhythm disruption and emotional symptoms are common.
 3 types of delirium are seen based on psychomotor activity:
   Mixed type
      o Psychomotor activity may remain stable at baseline or fluctuate rapidly
         between hyperactivity and hypoactivity.
      o Most common type.
   Hypoactive (“quiet”) type
      o Decreased psychomotor activity, ranging from drowsiness to lethargy
         to stupor
      o More likely to go undetected
      o More common in the elderly
                                                 37
   Hyperactive type (“ICU psychosis”)
     o Manifests with agitation/aggressive behavior, incoherent speech,
         disorganized thoughts, delusions, hallucinations and disorientation.
     o Less common, but more easily identified due to its disruptiveness
     o More common in drug withdrawal or toxicity
 Complete recovery occurs in most hospitalized patients within about 1 week,
  however, some cognitive deficits can persist for months or even remain
  indefinitely.
 Note: if a patient presents with altered mental status, disorientation, confusion,
  agitation or new-onset psychotic symptoms suspect delirium.
DIAGNOSIS
 Disturbance in attention and awareness
 Disturbance in an additional cognitive domain
 Develops acutely over hours to days, represents a change from baseline and
  tends to fluctuate
 Not better accounted for by another neurocognitive disorder
 Not occurring during a coma
 Evidence from history, physical or labs that the disturbance is a direct
  consequence of another medical condition, substance intoxication/withdrawal,
  exposure to toxin or due to multiple etiologies.

 TREATMENT
  Treat the underlying cause(s)
  Address potential exacerbating factors such as mobility limitations, sensory
   deficits, sleep cycle disruption, constipation, urinary retention, dehydration
   and electrolyte abnormalities, uncontrolled pain and use of unnecessary
   medications.
  Encourage a family member to stay at bedside to provide company and
   redirection as needed.
  Adequate supervision
  Reorient the patient on a regular basis by drawing attention to time, place and
   situation and by keeping whiteboards, calendars and clocks in plain sight
  Antipsychotics (D2 antagonist) are indicated for treatment of agitation that
   places the patient or others at risk.
  Haloperidol is the preferred agent and can be administered orally,
   intramuscularly or intravenously.
  D2 antagonist exacerbate extrapyramidal symptoms so use with caution in
   patients with Parkinsonism.
  Benzodiazepines (e.g. lorazepam) can cause, worsen or prolong delirium
   (paradoxical disinhibitions or over-sedation) so do not use unless treating
   delirium due to alcohol or benzodiazepine withdrawal.
  Avoid the use of restraints which may worsen agitation and cause injury.
  If restraints are necessary, use the least means appropriate for the situation and
   remove them as soon as the patient meets criteria for release.
A 75-year-old lady is found lying on the floor and taken to hospital. She is drowsy,
disorientated in time and place, distractible and unable to give any history. She thinks
you are trying to kill her. She is febrile and hypotensive but has no neurological signs or
injuries. Blood tests and X-rays are performed. She is given oxygen and antibiotics for
the clinical suspicion of septicemia. Her agitation worsens but settles with lorazepam.
The GP tell you that there is no past history to note. Blood cultures grow an organism
sensitive to the antibiotic. Her condition improves over 72 hours. The lorazepam is tailed
off and her cognitive function returns to normal.
              Diagnosis: acute confusional state secondary to bacteremia
                                         39
MOOD DISORDES
 Broadly speaking the emotions can be described as 2 main types:
   Affect, which is a short-lived emotional response to an idea or an event. It
      is the external expression of mood (it is objective).
   Mood: This is a description of one’s internal emotional state (it is
      subjective).
 According to these definitions, depression and mania are mood disorders and
  not ‘affective disorders’ as they have been called so frequently.
 Both external and internal stimuli can trigger moods, which may be labeled
  as sad, happy, angry, irritable and so on.
 It is normal to have a wide range of moods and to have a sense of control
  over one’s moods.
 Patients with mood disorders (also called affective disorders) experience an
  abnormal range of moods and lose some level of control over them.
 Distress may be caused by the severity of their moods and the resulting
  impairment in social and occupational functioning.
 Mood episodes are distinct periods of time in which some abnormal mood is
  present. They include hypomanic episode, manic episode, and a depressive
  episode.
 Mood disorders are defined by their patterns of mood episodes. They include
  major depressive disorder, Bipolar disorder (bipolar I and II), persistent
  depressive disorder (dysthymia) and cyclothymic disorder. Some may have
  psychotic features (delusions or hallucinations).
 When patients have delusions and hallucinations due to underlying mood
  disorders, they are usually mood congruent. For example, depression causes
  psychotic themes of paranoia and worthlessness, and mania causes psychotic
  themes of grandiosity and invincibility.
CLASSIFICATION
 According to the ICD-10, the mood disorders are classified as follows:
  1. Manic episode
  2. Depressive episode
  3. Bipolar mood (affective) disorder
  4. Recurrent depressive disorder
  5. Persistent mood disorder (including cyclothymia and dysthymia)
  6. Other mood disorder (including mixed affective episode and recurrent
     brief depressive disorder)
                                      40
MOOD EPISODES
MANIC EPISODE
 This is a distinct period of abnormally and persistently elevated, expansive
  or irritable mood and increased goal-directed activity or energy, lasting at
  least 1 week (or any duration if hospitalization is necessary).
 Episodes tend to last usually 3-4 months, followed by complete clinical
  recovery. The future episodes can be manic, depressive or mixed.
 Manic episodes include at least 3 of the following (4 if mood is only
  irritable):
   Distractibility
   Inflated self-esteem or grandiosity
   Increase in goal-directed activity (socially, at work, or sexually) or
      psychomotor agitation
   Decreased need for sleep
   Flight of ideas or racing thoughts
   More talkative than usual or pressured speech (rapid and uninterruptible)
   Excessive involvement in pleasurable activities that have a high risk of
      negative consequences (e.g. shopping sprees, sexual indiscretions)
 Symptoms are not attributable to the effects of a substance (drug or
  medication) or another medical condition, and they must cause clinically
  significant distress or social/occupational impairment.
 Greater than 50% of manic patients have psychotic symptoms.
                                      41
HYPOMANIC EPISODE
 A hypomanic episode is a distinct period of abnormally and persistently
  elevated, expansive or irritable mood, and abnormally and persistently
  increased goal-directed activity or energy, lasting at least 4 consecutive days
  that includes at least 3 of the symptoms listed for the manic episode criteria
  (4 if mood is only irritable)
 MANIA                                    HYPOMANIA
 Lasts at least 7 days                    Lasts at least 4 days
 Causes severe impairment in social or    No marked impairment in social or
 occupational functioning                 occupational functioning
 May necessitate hospitalization to       Does not require hospitalization
 prevent harm to self or others
 May have psychotic features              No psychotic features
 Note: for mixed features, criteria are met for a manic or hypomanic episode
  and at least 3 symptoms of a major depressive episode are present for the
  majority of the time. These criteria must be present nearly every day for at
  least 1 week.
MAJOR DEPRESSIVE EPISODE
 The typical depressive episode is characterized by the following features
  (which should last for at least 2 weeks for a diagnosis to be made):
   Depressed mood most of the time
   Anhedonia (loss of interest in pleasurable activities)
   Change in appetite or weight (increase or decrease)
   Feelings of worthlessness or excessive guilt
   Insomnia or hypersomnia
   Diminished concentration
   Psychomotor agitation or retardation (i.e. restlessness or slowness)
   Fatigue or loss of energy
   Recurrent thoughts of death or suicide
 Symptoms are not attributable to the effects of a substance (drug or
  medication) or another medical condition, and they must cause clinically
  significant distress or social/occupational impairment.
                                         42

MOOD DISORDERS
 Mood disorders often have chronic courses that are marked by relapses with
  relatively normal functioning between episodes.
 Like most psychiatric diagnoses, mood episodes may be caused by another
  medical condition or drug (prescribed or illicit), therefore, always investigate
  medical or substance-induced causes before making a primary psychiatric
  diagnosis.
 Medical condition causing depressive episodes:
   Cerebrovascular disease (stroke, myocardial infraction)
   Endocrinopathies: diabetes mellitus, Cushings syndrome, Addison
      disease, Hypoglycemia, Hyper/Hypothyroidism, Hyper/Hypocalcemia
   Parkinson’s disease
   Viral illnesses e.g. mononucleosis
   Carcinoid syndrome
   Cancer (especially lymphoma and pancreatic carcinoma)
   Collagen vascular disease e.g. Systemic lupus erythematosus
 Medical conditions causing manic episodes:
   Metabolic: hyperthyroidism
   Neurological disorders: temporal lobe seizures, multiple sclerosis
   Neoplasms
   HIV infection
                                        43
 Substance/Medication-induced depressive disorder: EtOH,
  antihypertensives, barbiturates, corticosteroids, levodopa, sedative-
  hypnotics, anticonvulsants, antipsychotics, diuretics, sulfonamides,
  withdrawal from stimulants e.g. cocaine, amphetamines
 Substance/ Medication-induced Bipolar disorder: Antidepressants,
  sympathomimetics, dopamine, corticosteroids, levodopa, bronchodilators,
  cocaine, amphetamines
DEPRESSIVE DISORDER
 Depression is a mood disorder that causes persistent feeling of sadness and
  loss of interest.
 It is called major depressive disorder or clinical depression.
 Depressive disorder is common. The risk is greatest in women and in those
  with a positive family history.
 Major depressive disorder is marked by episodes of depressed mood
  associated with loss of interest in daily activities.
 Patients may not acknowledge their depressed mood or may express vague
  somatic complaints (fatigue, headache, abdominal pain, muscle tension etc.)
 Onset can happen at any age but the age of onset peaks in the 20s.
 Depression can increase mortality for patients with other comorbidities such
  as diabetes, stroke and cardiovascular disease.
                                      44
CLINICAL FEATURES AND DIAGNOSIS
 The term ‘depression’ is widely used to describe low mood but in order for a
  diagnosis of depressive disorder to be made there are a number of key
  features that must be present for at least 2 weeks.
              ICD-10 CRITERIA FOR DEPRESSIVE DISORDER
                    A                                        B
  Persistent low mood                     Reduced concentration and
  Loss of interest or pleasure              attention
     (anhedonia)                           Reduced self-esteem and self-
  Fatigue or low energy (anergia)           confidence
                                           Ideas of guilt and worthlessness
                                           Hopelessness about the future
                                           Suicidal thoughts
                                           Disturbed sleep
                                           Diminished appetite
 The severity of the episode is determined by how many of these features are
 present:
      Mild: 2 or more from A + 2 from B (has some impact on daily life)
      Moderate: 2 or more from A + 3 from B (has significant impact on
        daily life)
      Severe: all 3 from A + 4 or more from B (impossible to get through
        daily life)
 If there has been more than one discrete episode this is termed recurrent
 depressive disorder.
                                        45
 Physical symptoms:
   Moving slowly (psychomotor retardation), speaking more slowly than
     usual, changes in appetite or weight (usually decreased, but sometimes
     increased), constipation, unexplained aches and pains
   Lack of energy, low sex drive (loss of libido), changes to menstrual cycle,
     disturbed sleep (finding it difficult to fall asleep at night or waking up
     very early in the morning or excessive sleepiness)
 Social symptoms:
   Not doing well at work, avoiding contact with friends, taking part in
     fewer social activities, neglecting one’s hobbies and interests, having
     difficulties in one’s home and family life.
RISK FACTORS
 Biochemistry: differences in certain chemicals (neurotransmitters) in the
  brain may contribute to symptoms of depression.
 Genetics: depression can run in families. For example, if one identical twin
  has depression, the other has a 70% chance of having the illness sometime in
  life.
 Personality: people with low self-esteem, who are easily overwhelmed by
  stress, or who are generally pessimistic appear to be more likely to
  experience depression.
 Environmental factors: continuous exposure to violence, neglect, abuse or
  poverty may make some people more vulnerable to depression.
PATHOPHYSIOLOGY
 The precise cause of depression is unknown, but major depressive disorder is
  believed to be a heterogeneous disease with biological, genetic,
  environmental and psychosocial factors contributing.
 The monoamine theory of depression postulates that depression results from
  a central deficiency in the monoamine neurotransmitters serotonin (5-HT),
  norepinephrine and dopamine.
   Evidence for this includes: antidepressants exert their therapeutic effect
     by increasing catecholamines, decreasing cerebrospinal fluid levels of 5-
     hydroxyindolacetic acid (5-HIAA), the main metabolite of serotonin in
     depressed patients with impulsive and suicidal behavior.
   Increased sensitivity of beta-adrenergic receptors in the brain has also
     been postulated in the pathogenesis of major depressive disorder.
 Other reported physiological features include increased cortisol and a
  blunted TSH response. GABA, Glutamate and endogenous opiates may
  additionally have a role.
                                      46
 However, there is no widely accepted and definitively proven biological
  model of depression.
 Psychosocial/life events: multiple adverse childhood experiences are a risk
  factor for later developing major depressive disorder.
   Loss of a parent before age 11 is associated with the later development of
     major depression.
 Genetics: first degree relative are 2 to 4 times more likely to have major
  depressive disorder. Concordance rate for monozygotic twins is <40% and
  10-20% for dizygotic twins.
                                      47
   Psychomotor retardation can increase to the point where the person sits
     motionless and mute-depressive stupor. This often used to be fatal (from
     dehydration), it now calls for emergency electroconvulsive therapy
     (ECT).
   Psychotic depression must be distinguished from other psychoses. This is
     based on the presence of other depressive symptoms and the mood
     congruity of the delusions and hallucinations.
 Atypical depression
   For some individuals depression is associated with increased sleep,
     increased appetite and phobic anxiety.
   This is often termed atypical depression and tends to respond better to
     monoamine oxidase inhibitors (MAOIs) rather than selective serotonin
     reuptake inhibitors (SSRIs).
 Reactive and endogenous depression
   This dated classification divided depression into ‘reactive depression’,
     brought on by a stressful life event and ‘endogenous depression’
     supposedly occurring from within the patient, with no clear external
     cause.
   Endogenous depression was thought to be more heritable and more
     responsive to antidepressant treatment. Research into depression has
     shown that such a division does not exist and these terms are rarely used
     now.
 Mixed anxiety and depressive disorder
   Anxiety symptoms are common in depressive disorder and when
     symptoms of both disorders are present but not individually sufficient
     enough to meet criteria for a diagnosis of a mood disorder or an anxiety
     disorder this is described as a mixed anxiety and depressive disorder.
TREATMENT
 Non-pharmacological: Psychotherapy
   Psychotherapy or “talk-therapy” is sometimes used alone for treatment of
    mild depression.
   For moderate to severe depression, psychotherapy is often used along
    with antidepressant medications.
   Cognitive behavioral therapy (CBT) has been found to be effective in
    treating depression.
    o CBT is a form of therapy focused on the present and problem solving.
    o CBT helps a person to recognize distorted thinking and then change
        behaviors and thinking.
                                      48
   Psychotherapy may involve only the individual but it can include others.
     For example, family or couples therapy can help address issues within
     these close relationships.
   Group therapy involves people with similar illnesses.
 Pharmacological: Antidepressants (SSRIs)
   Produce some improvement within the first week or two of use
   Full benefits may not be seen for 2 or 3 months.
   If a patient feels little or no improvement after several weeks, the doctor
     can alter the dose of the medication or add or substitute another
     antidepressant.
   In some situations, other psychotropic medication may be helpful.
 Electroconvulsive therapy (ECT)
   This is a medical treatment most commonly used for patients with severe
     major depression or bipolar disorder who have not responded to other
     treatments.
   It involves a brief electrical stimulation of the brain while the patient is
     under anesthesia.
   A patient typically receives ECT 2 to 3 times a week for a total of 6 to 12
     treatments.
   ECT has been used since 1940s, and many years of research have led to
     major improvements.
   It is usually managed by a team of trained medical professionals
     including a psychiatrist, an anesthesiologist and a nurse/clinical
     officer/medical licentiate.
                                       49
BIPOLAR DISORDER
 This disorder, earlier known as manic depressive psychosis is characterized
  by recurrent episodes of mania/hypomania (elated mood) and depression in
  the same patient at different times.
   The elevated mood is significant and is known as mania or hypomania,
      depending on its’s severity, or whether symptoms of psychosis are
      present.
 These episodes can occur in any sequence.
 The presence of elated mood alone is sufficient for the diagnosis to be made.
 The patients with recurrent episodes of mania (unipolar mania) are also
  classified here as they are rare and often resemble the bipolar patients in
  their clinical features.
 Bipolar mood disorder has an early age of onset of third decade. Unipolar
  depression, on other hand is common in 2 ages groups: late third decade and
  fifth to sixth decades.
 Unipolar depression usually last longer than bipolar depression.
 An average manic episode lasts for 3-4 months while a depressive episode
  lasts from 4-6 months.
 With rapid institution of treatment, the major symptoms of mania are
  controlled within 2 weeks and of depression within 6-8 weeks.
 The current episode in bipolar disorder is specified as one of the following
  (ICD-10):
   Hypomanic
   Manic without psychotic symptoms
   Manic with psychotic symptoms
   Mild or moderate depression
   Severe depression, without psychotic symptoms
   Severe depression, with psychotic symptoms
   Mixed or
   In remission
                                      50
 Bipolar mood disorder is further classified into:
   Bipolar I: characterized by episodes of severe mania and severe
     depression
   Bipolar II: characterized by episodes of hypomania (not requiring
     hospitalization) and severe depression
BIPOLAR I DISORDER
 Bipolar I disorder involves episodes of mania and of major depression
  however episodes of major depression are not required for the diagnosis.
 It is also known as manic-depression.
 The only requirement for this diagnosis is the occurrence of a manic episode
  (5% of patients experience only manic episodes). Between manic episodes,
  there may be interspersed euthymia, major depressive episodes, or
  hypomanic episodes but none of these are required for the diagnosis.
 Bipolar I disorders may have psychotic features (delusions or hallucinations)
  these can occur during major depressive or manic episodes.
   Remember to always include bipolar disorder in the differential diagnoses
      of a psychotic patient.
 Rapid cycling is defined by the occurrence of 4 or more mood episodes in 1
  year (major depressive, hypomanic or manic).
 Women and men are equally affected.
 No ethnic differences are seen.
 Onset is usually before age 30, mean age of first mood episode is 18.
ETIOLOGY
 Biological, environmental, psychosocial and genetic factors are all
  important.
 First degree relatives of patients with bipolar disorder are 10 times more
  likely to develop the illness.
 Concordance rates for monozygotic twins are 40-70%, and rates for
  dizygotic twins range from 5 to 25%.
 Bipolar I has the highest genetic link of all major psychiatric disorders.
                                       51
 TREATMENT
 Pharmacotherapy:
    Lithium is a mood stabilizer, 50-70% treated with lithium show partial
     reduction of mania. Long-term use reduces suicide risk. Acute overdose
     can be fatal due to its low therapeutic index.
     o Side-effects: weight gain, tremor, gastrointestinal disturbances,
        fatigue, cardiac arrhythmias, seizures, goiter/hypothyroidism,
        leukocytosis (benign), coma (in toxic doses), polyuria (nephrogenic
        diabetes insipidus), polydipsia, alopecia, metallic taste.
    The anticonvulsants carbamazepine and valproic acid are also mood
     stabilizers. They are particularly useful for rapid cycling bipolar disorder
     and those with mixed features.
    Atypical antipsychotics (risperidone, olanzapine, quetiapine, ziprasidone)
     are effective as both monotherapy and adjunct therapy for acute mania. In
     fact, many patients (especially with severe mania and/or with psychotic
     features) are treated with a combination of a mood stabilizer and
     antipsychotic, studies have shown a greater and faster response with
     combination therapy.
    Antidepressants are discouraged as monotherapy due to concerns of
     activating mania or hypomania. They are occasionally used to treat
     depressive episodes when patients concurrently take mood stabilizers.
    Treatment for bipolar disorder includes lithium, valproic acid and
     carbamazepine (for rapid cyclers), or second-generation antipsychotics.
     Lithium remains the gold standard, particularly due to demonstrated
     reduction in suicide risk.
 Psychotherapy:
    Supportive psychotherapy
    Family therapy
    Group therapy (may prolong remission once the acute manic episode has
     been controlled)
 Electroconvulsive therapy:
    Works well in treatment of manic episodes.
    Some patients require more treatments (up to 20) than for depression.
    Especially effective for refractory or life-threatening acute mania or
     depression.
    ECT is the best treatment for a pregnant woman who is having a manic
     episode. It provides a good alternative to antipsychotics and can be used
     with relative safety in all trimesters.
                                       52
BIPOLAR II DISORDER
 Alternatively called recurrent major depressive episodes with hypomania.
 History of one or more major depressive episodes and at least one
  hypomanic episode is needed for diagnosis. If there has been a full manic
  episode, even in the past, then the diagnosis is bipolar I, not bipolar II
  disorder.
 Bipolar II is frequently misdiagnosed as unipolar depression and thereby
  inappropriately treated.
 Prevalence is unclear, with some studies showing that it occurs more/less
  than bipolar I.
 It may be slightly more common in women.
   A patient with a history of postpartum mania has a high risk of relapse
      with future deliveries and should be treated with mood stabilizing agents
      as prophylaxis. However, some of these medications may be
      contraindicated in breast-feeding.
 Onset usually before age 30.
 No ethnic differences seen.
 Etiology is the same as bipolar I.
 Bipolar II tends to be chronic, requiring long-term treatment though it carries
  a better prognosis than bipolar I.
 Treatment is similar to bipolar I.
                                       53
PERSISTENT DEPRESSIVE DISORDER (DYSTHYMIA)
 Patients with persistent depressive disorder (dysthymia) have chronic
  depression most of the time, and they have discrete major depressive
  episodes.
 It is more common in women and has an onset often in childhood,
  adolescence and early adulthood.
 Dysthymia is characterized by:
   Depressed mood for the majority of the time most days for at least 2 years
      (in children or adolescents for at least 1 year)
   At least 2 of the following:
      o Poor concentration or difficult making decisions
      o Feelings of hopelessness
      o Poor appetite or overeating
      o Insomnia or hypersomnia
      o Low energy or fatigue
      o Low self-esteem
   During the 2-year period
      o The person has not been without the above symptoms for >2 months
          at a time
      o May have major depressive episode(s) or meet criteria for major
          depression continuously.
      o The patient must never have had a manic or hypomanic episode (this
          would make the diagnosis bipolar disorder or cyclothymic disorder
          respectively).
 Treatment:
   Combination treatment with psychotherapy and pharmacotherapy is more
      efficacious than either alone.
   Cognitive therapy, interpersonal therapy, and insight-oriented
      psychotherapy are the most effective.
   Antidepressants found to be beneficial include SSRIs, TCAs and MAOIs.
CYCLOTHYMIC DISODER
 This is characterized by alternating periods of hypomania and periods with
  mild-to-moderate depressive symptoms.
 It may coexist with borderline personality disorder.
 It occurs equally in males and females with an onset usually age 15-25.
 Cyclothymic disorder is characterized by:
   Numerous period with hypomanic symptoms (but not a full hypomanic
      episode) and periods with depressive symptoms (but not full major
      depressive episode) for at least 2 years.
                                      54
   The person must never have been symptom free for >2 months during
     those 2 years.
   No history of major depressive episode, hypomania or manic episode.
 Treatment is with antimanic agents (mood stabilizers or second-generation
  antipsychotics) as used to treat bipolar disorder.
                                     55
NEUROTIC, STRESS-RELATED AND
SOMATOFORM DISORDERS
 The terms neurosis and psychosis are currently not widely used. The
  definitions and description of these terms are far from perfect and there are
  clear exceptions to the rules.
 The ICD-10 still mentions the term neurotic in the classification, it
  discourages the use of the terms neurosis and psychosis.
 In ICD-10, ‘neurotic, stress-related and somatoform disorders’ have been
  classified into the following types:
   Phobic anxiety disorder: simple phobia/specific phobias, agoraphobia
   Other anxiety disorders (simply referred to as Anxiety disorders here):
      generalized anxiety disorder
   Obsessive compulsive disorder
 Neurosis (‘to do with nerves’) or neurotic disorder are the traditional terms
  for those symptoms when they are not due to an organ brain disease,
  psychosis or personality disorder.
 The symptoms of neurosis are emotional, cognitive, behavioral and somatic.
 Neuroses are often but not always associated with an external stressor.
   Anxiety is the primary emotion in all these disorders, although depressed
      mood is often present.
   The cognitions are worries, fears and concerns that are inappropriate or
      excessive but (by definition) not delusional.
   Behaviors include avoidance and other strategies intended to reduce
      anxiety such as repeated checking.
   Somatic (physical) symptoms, not explained by a medical disease but
      associated with tension, autonomic arousal and hyperventilation (such as
      aches and pains, bowel disturbance and breathlessness), are common.
 Neurotic disorders may present with the emotion of anxiety (e.g. attacks of
  panic) but may also present with one of the other symptoms such as
  cognitions e.g. recurrent worries about having a serious medical condition,
  behavior e.g. the agoraphobic unable to leave her house or somatic
  symptoms e.g. palpitations.
                                      56

ANXIETY DISORDER
 Anxiety is the commonest psychiatric symptom in clinical practice and
  anxiety disorders are one of the commonest psychiatric disorders in general
  population.
 Anxiety is a ‘normal’ phenomenon, which is characterized by a state of
  apprehension or unease arising out of anticipation of danger.
 Anxiety is an individual’s emotional and physical fear response to a perceived
  threat.
 Anxiety is often differentiated from fear, as fear is an apprehension in response
  to an external danger while in anxiety the danger is largely unknown (or
  internal).
 Normal anxiety becomes pathological when it causes significant subjective
  distress and/or impairment in functioning of an individual.
   Pathologic anxiety occurs when symptoms are excessive, irrational, out of
      proportion to the trigger or are without an identifiable trigger.
 Anxiety disorders are caused by a combination of genetic, biological,
  environment and psychosocial factors.
 Major neurotransmitter system implicated: norepinephrine (NE), serotonin (5-
  HT), and gamma-aminobutyric acid (GABA).
 Anxiety disorders affect more women compared to men (2:1).
 Symptoms of anxiety:
   Physical symptoms:
      o Constitutional: fatigue, diaphoresis (sweating), shivering (trembling)
      o Autonomic and visceral symptoms:
             Neurologic/musculoskeletal:          dizziness,      lightheadedness,
                paresthesias, tremors, insomnia, muscle tension, agitation,
                sweating, flushes, mydriasis
             Cardiac: Chest pain, palpitations, tachycardia, hypertension.
             Pulmonary: hyperventilation, shortness of breathing, dyspnea,
             Gastrointestinal: abdominal discomfort, dry mouth, anorexia,
                nausea, emesis, diarrhea, constipation
             Genitourinary: frequency and hesitancy of micturition
      o Motor symptoms: tremors, restlessness, muscle twitches, fearful facial
          expression
   Psychological symptoms
      o Cognitive symptoms: poor concentration, distractibility, hyperarousal,
          vigilance or scanning, negative automatic thoughts.
      o Perceptual symptoms: derealization, depersonalization
                                        58
     o Affective symptoms: diffuse, unpleasant and vague sense of
         apprehension, fearfulness, inability to relax, irritability, fear of loss of
         control, feeling of impending doom/dread (when severe)
     o Other symptoms: insomnia (initial), increased sensitivity to noise,
         exaggerated startle response obsessions and compulsions.
 Risk factors for most anxiety disorders:
   Family history (mild).
   Women are at higher risk, except OCD and social anxiety disorders.
   Onset is usually in teens and 20s. However, may rumble on untreated for
     years. Exception is GAD which is commonest in 40s and 50s.
   Life stressors: this can include physical illness.
 Medications and substances that cause anxiety: alcohol, sedatives/hypontics,
  cannabis,        hallucinogens       (phencyclidine,          lysergic        acid,
  methylenedioxymethamphetamine), stimulants (amphetamines, cocaine),
  caffeine, tobacco, and opioids.
                                         59
 Treatment includes pharmacological drugs and psychotherapy.
   Pharmacological drugs: drugs are used to achieve symptomatic relief and
     continue treatment for at least 6 months before attempting to titrate off
     medications.
     o First-line: Selective serotonin reuptake inhibitors (SSRIs) e.g. sertraline
        and serotonin-norepinephrine reuptake inhibitors (SNRIs) e.g.
        venlafaxine. Note: SSRIs typically take about 4-6 weeks to become
        fully effective and higher doses (than used in treating depression) are
        generally required.
            Sertraline initially 25mg daily for 1 week then increased to 50mg
              daily, then increased in steps of 50mg at intervals of at least 1
              week if required, maximum dose is 200mg per day. Increase dose
              only if response is partial and if drug is tolerated.
     o Benzodiazepine work quickly and effectively, but they all can be
        addictive. Minimize the use, duration and dose. Benzodiazepines
        should be avoided in patients with a history of substance use disorders,
        particularly alcohol.
            Note: if a patient has a comorbid depressive disorder, consider
              alternative to benzodiazepines as they may worsen depression.
              Use benzodiazepines to temporarily bridge patients until long-
              term medication becomes effective.
            Benzodiazepines should be avoided except for short-term relief
              during crises.
     o Busiprone (5-HT1a partial agonist): this is a non-benzodiazepine
        anxiolytic, however it is not commonly used due to mininmal efficacy
        and often only prescribed as augmentation.
     o Beta blockers (e.g. propranolol): may be used to help control autonomic
        symptoms with panic attack or performance anxiety.
     o Tricyclic antidepressants (TCAs) and monoamine oxidase inhibitors
        (MAOIs): May be considered if first-line agents are not effective. Their
        side-effect profile makes them less tolerable.
     o Note: warn that drugs will take 1 week to take effect and may initially
        cause transient increase in anxiety or agitation. Discuss suicide risk if
        under 30, offer proton pump inhibitors if on NSAIDs or aspirin, and
        warn against sudden cessation due to withdrawal effects.
   Psychotherapy:
     o Cognitive behavioral therapy (CBT): has been proven effective for
        anxiety disorders. CBT examines the relationship between anxiety-
        driven cognitions (thoughts), emotions and behaviors.
                                       60
      o Psychodynamic psychotherapy: facilitates understanding and insight
        into the development of anxiety and ultimately increases anxiety
        tolerance.
PANIC ATTACKS
 Panic attacks are a type of fear response involving an abrupt surge of intense
  anxiety which may be triggered or occur spontaneously.
 Panic attacks peak within minutes (10-20 mins) and usually resolve within
  half an hour.
 Patients may continue to feel anxious for hours afterwards and confuse this
  for a prolonged panic attack.
 Although classically associated with panic disorder, panic attacks can also be
  experienced with other anxiety disorders, psychiatric disorders and other
  medical conditions.
 Symptoms of panic attacks “Da PANICS” (4 symptoms have to be present
  for a panic attack to be diagnosed)
   D-       dizziness,      disconnectedness,     derealization     (unreality),
     depersonalization (detached from self)
   P- palpitations, paresthesias
   A- abdominal distress
   N- numbness, nausea
   I- Intense fear of dying, losing control or “going crazy”, intense
     apprehension
   C- chills, chest pain
   S- sweating, shaking, shortness of breath
 When a patient presents with a panic attack, rule out potentially life-
  threatening medical conditions such as heart attack, thyrotoxicosis and
  thromboembolism.
 Panic attacks may co-exisit with other psychiatric conditions such as
  depressive disorder, post-traumatic stress disorder and substance abuse.
PANIC DISORDER
 Panic disorder is characterized by spontaneous, recurrent panic attacks (2 or
  more). These attacks occur suddenly, “out of the blue”.
 Patients may also experience panic attacks with a clear trigger.
 The frequency of attacks ranges from multiple times per day to a few monthly.
                                       61
 Patients develop debilitating anticipatory anxiety about having future attacks-
  “fear of the fear” this can lead to avoidance behaviors and become so severe
  as to leave patients homebound (i.e. agoraphobia).
 Panic disorder associated with somatic symptoms and unpleasant feelings of
  depersonalization or derealization.
 Individuals with panic disorder may interpret their symptoms as a physical
  health problem.
 In panic disorder, the attacks are recurrent over a period of at least 1 month.
  Panic disorder is characterized by:
   Recurrent, unexpected panic attacks without an identifiable trigger.
   One or more of panic attacks followed by more than 1 month of continuous
      worry about experiencing subsequent attacks or their consequences and/or
      a maladaptive change in behaviors e.g. avoidance of possible triggers.
   Not caused by the direct effects of a substance, another mental disorder, or
      another medical condition.
 Panic disorder has a greater risk if first-degree relative is affected. It is
  associated with increased incidence of stressors (especially loss) prior to onset
  of disorder, history of childhood physical or sexual abuse.
 Panic disorder is higher in women compared to men (2:1).
 Median age of onset: 20-24 years old.
 Other comorbid syndromes include other anxiety disorders (especially
  agoraphobia), bipolar disorder, depression and alcohol use disorder.
 Treatment:
   Pharmacotherapy:
      o First-line: SSRIs (e.g. sertraline, citalopram, escitalopram). Allow 12
         weeks to see if effective, they have sedative and relaxing effects.
         Counsel as always on side effects.
             Sertraline initially 25mg daily for 1 week then increased to 50mg
               daily, then increased in steps of 50mg at intervals of at least 1
               week if required, maximum 200mg per day. Increased only if
               response is partial and if drug is tolerated.
      o Can switch to TCAs (clomipramine, imipramine) if SSRIs not effective.
      o Continue for at least 6 months if effective.
      o Can use benzodiazepines (clonazepam, lorazepam) as scheduled or
         PRN (as needed) especially until the other medications reach full
         efficacy.
      o If severe antiseizure medication can be prescribed.
   Psychotherapy:
      o Cognitive behavioral therapy- 7-14 weekly sessions. It involves:
                                        62
           Patient learning about the panic disorder and how to identify
             certain symptoms.
           Monitor panic attacks using a diary
           Breathing and relaxation techniques
           Change in beliefs about panic attacks
           The patient allowing themselves to be exposed to certain
             situations that provoke panic attacks
      o Psychoeducation for patient and family.
      o Social: Peer support groups
PHOBIC DISORDER
 Phobia is defined as an irrational fear of a specific object, situation or activity,
  often leading to persistent avoidance of the feared object, situation or activity.
 The common types of phobias are:
   Agoraphobia
   Social phobia
   Specific (Simple) phobia
 Characteristics of phobia:
   Presence of the fear of an object, situation or activity
   The fear is out of proportion to the danger perceived
   Patient recognizes the fear as irrational and unjustified (insight is present)
   Patient is unable to control the fear and is very distressed by it
   This leads to persistent avoidance of the particular object, situation or
     activity
   Gradually, the phobia and the phobic object become a preoccupation with
     the patient, resulting in marked distress and restriction of the freedom of
     mobility (afraid to encounter the phobic object, phobic avoidance).
AGORAPHOBIA
 Agoraphobia is intense fear of being in public places where escape or
  obtaining help may be difficult.
 It often develops with panic disorder.
 The course of the disorder is usually chronic.
 Avoidance behaviors may become as extreme as complete confinement to the
  home.
 Onset is usually before age 35.
 In Agoraphobia:
   Intense fear/anxiety about >2 situations due to concern of difficult escaping
      or obtaining help in case of panic or other humiliating symptoms:
      o Outside of the home alone
                                         63
     o Open spaces (e.g. bridges)
     o Enclosed places (e.g. stores)
     o Public transportation (e.g. trains)
     o Crowds/lines
   The triggering situations cause fear/anxiety out of proportion to the
     potential danger posed, leading to endurance of intense anxiety, avoidance
     or requiring a companion. This holds true even if the patient suffers from
     a medical condition such as inflammatory bowel disease (IBS) which may
     lead to embarrassing public scenarios.
   Symptoms cause significant social or occupational dysfunction.
   Symptoms last more 6 months.
   Symptoms not better explained by another mental disorder.
 Comorbid diagnoses include other anxiety disorders, depressive disorders and
  substance use disorders.
 During diagnosis a history is taken asking specific questions e.g. medications
  taken as well as a physical examination to rule out conditions that may present
  with anxiety.
 Treatment is essentially the same as panic disorder. (CBT and SSRIs)
   Psychotherapy: CBT
     o Systematic desensitization: a person is gradually exposed to the feared
        object/situation/activity
            Patient identifies the anxiety
            Patient learns coping techniques
            The patient uses learnt techniques to cope with various situations
   Drugs: SSRIs
     o Sertraline initially 25mg daily for 1 week then increased to 50 mg daily,
        then increased in steps of 50mg at intervals of at least 1 week if required,
        maximum dose is 200mg per day. Increase only if response is partial
        and if drug is tolerated.
SOCIAL PHOBIA
   Fear of social situations and interactions.
   Fearful of being embarrassed or judged by others.
   Anticipatory anxiety may be present
   Physical symptoms: trembling, blushing and derealization. Person may get
    performance anxiety (a specific type of social anxiety restricted to
    performance).
                                        64
 In social phobia:
   Individuals fear acting in a way that might make them get judged.
   The phobia interferes with normal routine and relationships.
   The fear of anxiety is persistent (>6 months)
 Treatment same as agoraphobia.
   Beta-blockers may be used for performance anxiety.
SPECIFIC (SIMPLE) PHOBIA
 These are irrational fears of specific objects or situations e.g.
   Fear of animals e.g. arachnophobia (fear of spiders), alektorophobia (fear
     of chickens), ophidiophobia (fear of snakes), cynophobia (fear of dogs)
   Fear of natural environment e.g. nyctophobia (Fear of the dark),
     Astrophobia (fear of lightening)
   Fear of blood and needles (hemophobobia)
   Fear of situations e.g. flying (aviophobia), claustrophobia (fear of enclosed
     spaces), Acrophobia (fear of heights)
   Others e.g. fear of clowns (coulrophobia)
 Treatment same as agoraphobia.
 Treat any co-morbidity.
GENERALIZED ANXIETY DISORDER
 Patients with GAD have persistent, excessive anxiety about many aspects of
  their daily lives (e.g. money, work, finances, home, relationships)
 Some symptoms GAD include irritability, edginess, impaired concentration,
  restlessness and “blacking out” of the mind.
 Often, they experience somatic symptoms including insomnia, fatigue, muscle
  tension/aches (clench jaw or teeth grinding) and bowel symptoms (diarrhea or
  constripation).
 Generalized anxiety disorder (GAD) is characterized by an insidious onset in
  the 3rd decade and a stable, usually chronic course which may or may not be
  punctuated by repeated panic attacks (episodes of acute anxiety).
 GAD is persistent anxiety associated with chronic uncontrollable and
  excessive worry. It may fluctuate in severity but is not paroxysmal (as with
  panic), situational (as with phobia), life-long (as with personality disorder) or
  clearly stress related (as with a stress-related disorder).
 GAD rates are higher in women compared to men (2:1).
 Age of onset: 30 years.
 The symptoms of anxiety should last for at least a period of 6 months for a
  diagnosis of generalized anxiety disorder to be made and 3 of the mentioned
  symptoms should be present (in children only 1 is needed).
                                        65
 As anxiety is a cardinal feature of almost all psychiatric disorders, it is very
  important to exclude other diagnoses.
 The most important differential diagnosis is from depressive disorders and
  organic anxiety disorder.
 Comorbid diagnoses include other anxiety disorders and depressive disorders.
 Treatment:
   The most effective treatment approach combines psychotherapy and
     pharmacology
   Cognitive behavioral therapy: teaches different ways of thinking, behaving
     and reacting.
   Selective serotonin reuptake inhibitors (e.g. sertraline, citalopram) or SNRI
     (e.g. venlafaxime)
   Can also consider a short-term course of benzodiazepines or augmentation
     with buspirone
   Much less commonly used medications are TCAs and MAOIs
                                       66
MANAGEMENT
 Psychotherapy: Cognitive behavioral therapy
   Exposure therapy: exposure to fears in a safe and controlled environment
     through mental imagery, writing or visits to the place where traumatic
     event happened.
   Cognitive restructuring: patients are helped to make sense of their bad
     memories.
 Trauma focused CBT (8-12 sessions): include psychoeducation, anxiety and
  anger management, breathing techniques and exposure to triggers in a
  controlled environment.
   Eye movement desensitization and reprocessing (EMDR): eye movements
     while focusing on the memory.
 Pharmacological therapy:
   SSRIs: Sertraline (Zoloft) initially 50mg daily, then increased in steps of
     50mg at intervals of at least 1 week if required, maintenance 50mg daily,
     maximum 200mg per day.
   Alternatively, paroxetine (paxil) can also be used.
   Benzodiazepines can also be prescribed though their use is limited due to
     dependence.
 Sleep-aids, Group therapy and Support groups have also been shown to be
  effective.
 Treat PTSD before treating secondary co-morbid conditions unless they are
  so severe that they prevent effective PTSD treatment.
   PTSD is most commonly associated with substance abuse (alcohol)
                                      67
OBSESSIVE-COMPULSIVE DISORDER
 An obsession is defined as:
   An idea, impulse or image which intrudes into the conscious awareness
     repeatedly.
   It is recognized as one’s own idea, impulse or image but is perceived as
     ego-alien (foreign to one’s personality).
   It is recognized as irrational and absurd (insight is present).
   Patient tries to resist against it but is unable to.
   Failure to resist, leads to marked distress.
 An obsession is usually associated with compulsion(s). A compulsion is
  defined as:
   A form of behavior which usually follows obsessions.
   It is aimed at either preventing or neutralizing the distress or fear arising
     out of obsession.
   The behavior is not realistic and is either irrational or excessive.
   Insight is present, so the patient realizes the irrationality of compulsion.
   The behavior is performed with a sense of subjective compulsion (urge or
     impulse to act).
 Lifetime prevalence: 2-3%.
 Mean age of onset: 20 years old.
 No gender difference in prevalence overall.
CLINICAL SYNDROMES
 ICD-10 classifies OCD into 3 clinical subtypes:
   Predominantly obsessive thoughts or ruminations
   Predominantly compulsive acts (compulsive rituals)
   Mixed obsessional thoughts and acts
 Depression is very commonly associated with obsessive compulsive disorder.
 4 clinical syndromes have been described in literature, although admixtures
  are commoner than pure syndromes.
   Washers
     o This is the commonest type. Here the obsession is of contamination with
         dirt, germs, body excretions and the like.
     o The compulsion is washing of hands or the whole body, repeatedly
         many times a day.
    Checkers
     o Persons constantly obsesses usually about the safety of something and
       this leads to repetitive checking.
                                       68
    Pure obsessions:
     o This syndrome is characterized by repetitive intrusive thoughts,
        impulses or images which are not associated with compulsive acts.
     o The content is usually sexual or aggressive in nature.
     o The distress associated with these obsessions is dealt usually by
        counter-thoughts (such as counting) and not by behavioral rituals.
     o A variant is obsessive rumination, which is a preoccupation with
        thoughts.
     o Here, the person repetitively ruminates in his mind about the pros and
        cons of the thought concerned.
    Primary obsessive slowness:
     o A relatively rare syndrome, it is characterized by severe obsessive ideas
        and/or extensive compulsive rituals, in the relative absence of
        manifested anxiety.
     o This leads to marked slowness in daily activities.
TREATMENT
 Psychotherapy:
   Psychoanalytic psychotherapy is used in certain selected patients who are
     psychologically oriented.
   Supportive psychotherapy is an important adjunct to other modes of
     treatment. Supportive psychotherapy is also needed by the family
     members.
 Behavior therapy and Cognitive behavior therapy:
   Behavior modification is an effective mode of therapy, with a success rate
     as high as 80%, especially for the compulsive acts.
   The techniques used are listed below:
     o Thought-stopping (and its modifications)
     o Response prevention
     o Exposure and response therapy
     o Systemic desensitization
     o Modelling
 Pharmacology:
   Antidepressants: some patients may improve dramatically with specific
     serotonin reuptake inhibitors (SSRIs).
   Antipsychotics: these are occasionally used in low doses (e.g. haloperidol,
     risperidone, olanzapine, aripiprazole, pimozide) in the treatment of severe,
     disabling anxiety.
                                       69
   Benzodiazepine (e.g. alprazolam, clonazepam) have a limited role in
     controlling anxiety as adjuncts and should be used very sparingly.
   Buspirone has also been used beneficially as an adjunct for augmentation
     of SSRIs, in some patients.
 Electroconvulsive therapy: in presence of severe depression with OCD, ECT
  may be needed. ECT is particularly indicated when there is a risk of suicide
  and/or when there is a poor response to the other modes of treatment.
  However, ECT is not the treatment of first choice in OCD.
 Psychosurgery: psychosurgery can be used in treatment of OCD that has
  become intractable and is not responding to other methods of treatment. It is
  worth
                                      70
PERSONALITY DISORDERS
 Personality describes the characteristic behavioral, emotional and cognitive
  attributes of an individual.
   Personality is the way of thinking, feeling and behavior that makes a person
      different from other people.
   An individual’s personality and tendencies are influenced by experiences
      and environment e.g. (surroundings, life situations) and inherited
      characteristics.
   A person’s personality typically stays the same over time.
   Biological, genetic, and psychosocial factors during childhood and
      adolescence contribute to the development of personality disorders.
   The prevalence of some personality disorders in monozygotic twins is
      several times higher than in dizygotic twins.
 It is only when certain personality traits are extreme enough to cause problems
  for the person or others that a personality disorder is defined.
   A personality disorder is a way of thinking, feeling and behaving that
      deviates from the expectations of the culture, society and causes distress or
      problems in functioning and lasts over time.
   Personality disorders are long-term patterns of behavior and inner
      experiences that differ significantly from what is expected.
   The pattern of experience and behavior begins by late adolescence or early
      adulthood and causes distress or problems in functioning.
   Without treatment, personality disorders can be long-lasting.
 Personality disorders affect and impact at least 2 of these areas (mnemonic=
  CAPRI):
   Cognition: Way of thinking about oneself and others
   Affect: Way of responding emotionally
   Personal relations: Way of relating to other people
   Impulse control: Way of controlling one’s behavior
 Although personal distress may occur in some personality disorder, classically
  the abnormal personality traits are ‘ego-syntonic’. This is in sharp contrast to
  the symptoms in neurotic disorder which are ‘ego dystonic’ and hence cause
  significant distress to the patient. So, unlike the patient with neurotic
  disorders, several personality disorder patients do not usually seek psychiatric
  help unless other psychiatric symptoms co-exist.
 Although personality disorders are usually recognizable by early
  adolescences, they are not typically diagnosed before early adult life.
 The symptoms continue unchanged through the adult life and usually become
  less obvious in the later years of life (after 40 years of age).
                                        71
 The life-time prevalence of personality disorders in the general population is
  about 5-10%.
 Often symptoms of more than one personality disorder are present in one
  person. In fact, it is now believed that the occurrence of mixed personality
  disorders is commoner than single personality disorders.
 Many patients will meet the criteria for more than one personality disorder,
  they should be classified as having all of the disorders for which they qualify.
CLASSIFICATION
 Personality disorder in ICD-10 is divided into 10 types. The validity and
  reliability of these categories is limited. Most patients seem to fit several
  descriptions or none of them.
 A simpler option, from DSM-5 is to use 3 clusters, which encompass the
  individual categories.
   Cluster A (“Eccentric”/ “Weird”): Patients seem eccentric, peculiar or
      withdrawn. There is a familial association with psychotic disorders (i.e.
      schizophrenia).
      o Paranoid- “accusatory”
      o Schizoid- “Aloof”
      o Schizotypal- “Awkward”
   Cluster B (“dramatic”/ “wild”): Patients seem emotional, dramatic or
      inconsistent. There is a familial association with mood disorders.
      o Antisocial (dissocial, psychopathic)
      o Borderline (emotionally unstable)
      o Histrionic
      o Narcissistic
   Cluster C (“anxious”/ “worried”): Patients seem anxious or fearful. There
      is a familial association with anxiety disorders.
      o Avoidant (anxious/ “cowardly”)
      o Obsessive compulsive (“compulsive”)
      o Dependent (“Clingy”)
CLUSTER A (ECCENTRIC/ WEIRD)
 These are thought to be “odd and eccentric” and on a “schizophrenic-
  continuum”
 This cluster includes:
   Paranoid
   Schizoid
   Schizotypal
                                       72
PARANOID PERSONALITY DISORDER (“ACCUSATORY”)
 Patients show a behavior pattern of being suspicious of others and generally
  distrustful. They see others as mean or spiteful.
 They often assume that people will harm them or deceive them.
 They tend to blame their own problems on others and seem angry and hostile.
  They react severely if they feel they have been lied to or slighted.
 The patients may become involved in litigation on small issues.
 They are often characterized as being pathologically jealous, which leads them
  to think that their sexual partners or spouses are cheating on them. They tend
  to hold grudges.
 They have superficial relationships and live in isolation as they avoid being
  close to people.
 Psychodynamically, the underlying defense mechanism is projection.
 Prevalence: 2-4%. It is more commonly diagnosed in men than in women.
 Treatment:
   Psychotherapy is the treatment of choice (individual psychotherapy and
      supportive psychotherapy)
   Patients may also benefit from a short course of antipsychotics for transient
      psychosis
   Group psychotherapy should be avoided due to mistrust and
      misinterpretation of others’ statements
    A 30-year- old man says his wife has been cheating on him because he
      does not have a good enough job to provide for her needs. He also
    claims that on his previous job, his boss laid him off because he did a
      better job than his boss. He has initiated several lawsuits. Refuses
     couples’ therapy because he believes the therapist will side with his
                  wife. Believes neighbors are critical of him.
                  Diagnosis: Paranoid personality disorder
 Differential diagnosis:
   Delusional (paranoid) disorders
   Paranoid schizophrenia
 Note: unlike patients with schizophrenia, patients with paranoid personality
  disorder do not have any fixed delusions and are not frankly psychotic,
  although they may have transient psychosis under stressful situations.
                                       73
SCHIZOID PERSONALITY DISORDER (“ALOOF”)
 Patients with schizoid personality disorder have a lifelong pattern of social
  withdrawal.
 They are often perceived as eccentric (Strange) and withdrawn.
 They express little emotion or feeling and typically do not seek close
  relationships.
 They choose to be alone or enjoy lonely life.
 They seem not to care about praise or criticism.
 They find physical contact less pleasurable e.g. sexual activity or holding
  hands.
 They have a flat affect or emotional blunting- they don’t show positive or
  negative emotions.
 Prevalence: 3-5%. Diagnosed more often in men than women.
 Treatment:
   Lack insight for individual psychotherapy, and may find group therapy
      threatening, may benefit from day programs and drop-in centers.
   Antidepressants if comorbid major depression is diagnosed.
    A 45-year- old scientist works in the lab most of the day and has no
    friends, according to his coworkers. Has not been able to keep his job
    because of failure to collaborate with others. He expresses no desire to
    make friends and is content with his single life. He has no evidence of
    a thought disorder
                  Diagnosis: Schizoid personality disorder
                                       74
 They have few social relations but have strong desires to have them though
  they are unable to maintain them.
 Prevalence: 4-5%.
 Treatment:
   Psychotherapy is the treatment of choice to help develop social skills
     training
   Short course of low-dose antipsychotics if necessary (for transient
     psychosis). Antipsychotics may help decrease social anxiety and suspicion
     in interpersonal relationships.
                                      75
ANTISOCIAL PERSONALITY DISORDER
    These show a pattern of disregarding or violating the rights of others (callous
    unconcern).
   They have little empathy, compassion and remorse for their actions.
   They disregard moral values and societal norms.
   They have a low threshold (tolerance) to frustration and a low threshold for
    discharge of aggression & irritability.
   They are impulsive, deceitful and often violate the law.
     They may repeatedly lie or deceive others, or may act impulsively i.e. they
       can be charming and use this to manipulate others for their personal gain.
     They are frequently skilled at reading social cues and can appear charming
       and normal to others who meet them for the first time and do not know
       their history
   They are often willing to hurt others if it helps them, this predisposes them to
    aggressive and unlawful behavior and at times carrying the label “sociopath”
    or “psychopath”.
     This disorder is synonymous with previously used terms such as
       psychopathy and sociopathy but does not always mean criminal behavior.
   This type of personality tends to be overrepresented in prison populations and
    they show higher rates of substance abuse.
   Individuals must be over 18 years with a history of conduct disorder in order
    to meet the diagnosis.
   This disorder is diagnosed more commonly in males.
   The course is usually chronic, however there is some decrease in the
    symptoms after the fifth decade of life in some patients.
   Treatment:
     Patients often do not seek psychiatric help and if they do, it is usually under
       pressure from the legal authorities.
     The therapeutic alliance is often not sustained.
     Treatment methods:
       o Individual psychotherapy
       o Psychoanalysis or psychoanalytical psychotherapy
       o Group psychotherapy and self-help groups
       o Pharmacotherapy: is of little help. Pharmacotherapy may be used to
           treat symptoms of anxiety or depression, but use caution due to high
           addictive potential of these patients.
     Note: psychotherapy is generally ineffective.
                                         76
    A 30-year- old unemployed man has been accused of killing three
    senior citizens after robbing them. He is surprisingly charming in the
    interview. In his adolescence, he was arrested several times for stealing
    cars and assaulting other kids.
                  Diagnosis: Antisocial personality disorder
                                       77
      prominent. Pharmacotherapy is not the treatment of first choice in
      borderline personality disorder.
       A 23-year- old medical student attempted to cut her wrist because
       things did not work out with a man she had been dating over the past 3
       weeks. She states that guys are jerks and “not worth her time”. She
       often feels that she is “alone in this world”.
                     Diagnosis: Borderline personality disorder
                                        78
NARCISSISTIC PERSONALITY DISORDER
 They display behavior that attracts need for admiration.
 They lack empathy for others.
 Displays a grandiose sense of self-importance.
 Displays a sense of entitlement
 Takes advantage of others.
 Despite these features they present with, they have a fragile self-esteem
  (vulnerable to criticism and lash out when feeling slighted).
 They come across as pretentious, self-centered and entitled often exploiting
  others as they only get involved in situations that advance personal agenda.
 There is a higher incidence of depression and midlife crises since these
  patients put such a high value on youth and power.
 Treatment:
   Psychotherapy is the treatment of choice.
   Antidepressants may be used if a comorbid mood disorder is diagnosed.
CLUSTER C (ANXIOUS/WORRIED)
 Cluster C has disorders considered “anxious and fearful” and characterized by
  “introversion”.
 They include
   Avoidant
   Obsessive compulsive
   Dependent
AVOIDANT PERSONALITY DISORDER
 Disposition of a pattern of extreme shyness. They are shy, timid and socially
  inhibited with low self-esteem.
 They view themselves as incapable, inadequate and undesirable.
 They often want close relationships but rarely take social risks and avoid
  social situations making it hard for them to meet people.
 They are hypersensitive to rejection and criticism becoming even more
  withdrawn when they happen.
                                      79
 They only accept involvement if they are certain of being liked.
 They are often preoccupied with being criticized or rejected.
 May view themselves as not being good enough or socially incompetent.
 There is a considerable overlap between avoidant personality and social
  phobias. One key difference is social phobias focus on anxiety of specific
  situations e.g. public speaking while avoidant personality is associated with
  anxiety of general situations.
 Avoidant personality disorder is equally frequent in males and females.
 There is an increased incidence of associated anxiety and depressive disorders.
 Treatment:
   Individual psychotherapy
   Group therapy
   Behavior therapy: in particular, social skills training and assertiveness
      training are useful.
   CBT: the focus is on negative thoughts and negative self-appraisal.
   Selective serotonin reuptake inhibitors (SSRIs) may be prescribed for
      comorbid social anxiety disorder or major depression.
    A 30-year- old postal worker rarely goes out with her coworkers and
    often makes excuses when they ask her to join them because she is
    afraid they will not like her. She wishes to go out and meet new people
    but, according to her, she is too “shy”.
                  Diagnosis: Avoidant personality disorder
                                       80
 OCD is ego-dystonic because the person wishes they could stop the behavior
  however OCPD is ego-syntonic because the person is generally happy with
  how they are and don’t want to change anything about them.
 Men are two times more likely to have OCPD than women.
 Treatment:
   Psychotherapy is the treatment of choice.
     o Cognitive-behavior therapy may be particularly useful.
     o Group psychotherapy.
   Pharmacotherapy may be used to treat associated symptoms as necessary.
    A 40-year- old secretary has been recently fired because of her inability
    to prepare some work projects in time. According to her, they were not
    in the right format and she had to revise them six times, which led to
    the delay. This has happened before but she feels that she is not given
    enough time.
            Diagnosis: Obsessive-compulsive personality disorder
                                       81
    A 40-year- old man who lives with his parents has trouble deciding
    how to get his car fixed. He calls his father at work several times to ask
    very trivial things. He has been unemployed over the past 3 year.
                  Diagnosis: Dependent personality disorder
DIAGNOSIS
 According to ICD-10, the diagnostic guidelines for specific personality
  disorder include conditions not directly attributable to gross brain damage or
  disease, or to another psychiatric disorder, meeting the following criteria:
  1. Markedly disharmonious attitudes and behavior involving usually several
     areas of function e.g. Cognition, Affect, Personal relations, and Impulse
     control.
  2. The abnormal behavior pattern is enduring of longstanding and not limited
     to episodes of mental illness.
  3. The abnormal behavior pattern is pervasive and clearly maladaptive to a
     broad range of personal and social situations.
  4. The manifestations always appear during childhood or adolescence and
     continue into adulthood. People under 18 are typically not diagnosed with
     personality disorder because their personalities are still developing.
  5. The disorder leads to considerable personal distress but this may only
     become apparent late in its course.
  6. The disorder is usually but not invariable, associated with significant
     problems in occupational and social performance.
TREATMENT
 Personality disorders are generally very difficult to treat, especially since few
  patients are aware that they need help. The disorders tend to be chronic and
  lifelong.
 In general, pharmacologic treatment has limited usefulness except in treating
  comorbid mental conditions e.g. major depressive disorder
   There are no medications specifically to treat personality disorders.
      However, medication, such as antidepressants, antianxiety medication or
      mood stabilizing medication, may be helpful in treating some symptoms.
   More severe or long lasting symptoms may require a team approach
      involving a primary care provider or doctor, a psychiatrist, a psychologist,
      social worker and family members.
                                        82
 Psychotherapy is usually the most helpful.
   During psychotherapy, an individual can gain insight and knowledge about
     the disorder and what is contributing to symptoms and can talk about
     thoughts, feelings and behaviors.
   Psychotherapy can help a person understand the effects of their behavior
     on others and learn to manage or cope with symptoms.
   Psychotherapy can help to reduce behavior causing problems with function
     and relationships.
   Commonly used types of psychotherapy:
     o Psychoanalytic/Psychodynamic therapy
     o Dialectical behavior therapy
     o Cognitive behavioral therapy
     o Group therapy
     o Psychoeducation (teaching the individual and family members about
         the illness, treatment and ways of coping)
 Psychodynamic approach:
   Some examples of assumptions that drive the psychodynamic approach
     are:
     o The unconscious is one of the most powerful effects on behavior and
         emotion.
     o No behavior is without cause and is therefore determined.
     o Childhood experience greatly affect emotions and behavior as adults.
     o The psychodynamic approach includes all the theories in psychology
         that see human functioning based upon the interaction of drives and
         forces within the person.
     o They focus particularly on the unconscious and between the different
         structures of the personality.
     o Sigmund Freud’s psychoanalysis is both a theory and therapy.
 Psychoanalysis is also known as “talk therapy”.
   Psychoanalysis and psychodynamic therapies.
   This approach focuses on changing problematic behaviors, feelings, and
     thoughts by discovering their unconscious meanings and motivations e.g.
     in Behavior therapy, Cognitive therapy, Humanistic therapy and
     Integrative or holistic therapy
 Dialectical behavior therapy: Dialectical behavior therapy is an evidence-
  based psychotherapy that began with efforts to treat Borderline Personality
  disorders. DBT has been proven useful in treating mood disorders, suicidal
  ideation and for change in behavioral patterns such as self-harm and substance
  abuse.
                                      83
FACTITIOUS                   DISORDER                 (MUNCHAUSEN
SYNDROME)
 Munchausen syndrome (also known variously as hospital addiction, hospital
  hobo syndrome, peregrinating (wandering) problem patients, polysurgical
  addiction, hospital vagrant or professional patients) is used for those patients
  who repeatedly simulate or fake disease for the sole purpose of obtaining
  medical attention.
 There is no other recognizable motive (hence, it is different from malingering).
 Patients with factitious disorder intentionally fake medical or psychological
  signs and symptoms in order to assume the role of a sick patient.
 Factitious disorder is more common in women. It accounts for at least 1% of
  hospitalized patients with a higher incidence in hospital and health care
  workers (who have learned how to feign symptoms).
 Factitious disorder is associated with personality disorders and many patients
  have a history of illness and hospitalization, as well as childhood physical or
  sexual abuse i.e. deprivation and neglect.
 The cause is not clear. Probably these patients are masochistic, seek
  dependency from a father-figure (e.g. the physician), attempt to manoeuver
  control over the father-figure and see the surgical procedure as partial suicide.
CLINICAL FEATURES
 Factitious disorders can present with predominantly physical signs and
  symptoms, or psychological signs and symptoms or combined signs and
  symptoms.
 The patients distort their clinical histories, laboratory test reports and even
  facts about other aspects of their lives (pseudologia fantastica).
 Sometimes they distort physical signs by self-inflicted injuries and secondary
  infections. Drug abuse especially abuse of prescription drugs is common.
 Evidence of earlier treatment, usually surgical procedures is often available in
  the form of multiple scars (e.g. grid-iron abdomen).
 These patients are often manipulative and convincingly tell lies, create
  problems in the inpatient setting and often leave against medical advice
  usually after the surgical procedure has been performed.
 Psychological signs and symptoms:
   Patients with factitious disorders may simulate psychological conditions
     and psychiatric disorder.
                                        84
   A patient may feign/simulate/pretend bereavement by reporting that
     someone to whom he or she was close has died or been killed in an
     accident.
   A patient may simulate symptoms of posttraumatic stress disorder.
   Provide false reports of previous trauma (e.g. a civilian accident or combat
     experience)
   Closely related to factitious posttraumatic stress disorder is the false
     victimization syndrome, in which the patient falsely claims some type of
     abuse. A woman may falsely report that she had been raped.
   Other simulated psychological disorder includes various forms of
     dementia, amnesia, or fugue, multiple personality disorder and more rarely
     schizophrenia.
 Physical signs and symptoms:
   The production of physical symptoms or disease is probably the most
     common form of factitious disorder.
   Essentially medical diseases and symptoms have been either simulated or
     artificially produced at one time or another.
   Among the most common of these disorders are:
     o Factitious hypoglycemia
     o Factitious anemia
     o Factitious gastrointestinal bleeding
     o Pseudoseizures
     o Simulation of brain tumors
     o Simulation of renal colic
     o More recently simulation of AIDS
 Combined psychological and physical signs and symptoms:
   A patient may be admitted to the hospital with factitious physical
     symptoms. In the course of hospitalization, perhaps in an attempt to obtain
     more sympathy or interest, may report or simulate a variety of
     psychological symptoms.
   Having experienced the recent loss of close relative or friend or having
     been raped in the past.
 Factitious disorder not otherwise specified:
   This category is reserved for forms of factitious disorder that do not fit one
     of the other categories.
   It includes the Munchausen syndrome by proxy, in which one person
     secretly induces disease or reports disease in another person.
   Most commonly, this is the behavior of a mother in reference to the child
     or baby
                                       85
DIAGNOSIS
 Falsification of physical or psychological signs or symptoms or induction of
  injury or disease, associated with identified deception.
 The deceptive behavior is evident even in the absence of obvious external
  rewards (such as in malingering).
 Behavior is not better explained by another mental disorder such as delusional
  disorder or another psychotic disorder.
 Individual can present him/herself or another individual (as in factitious
  disorder imposed on another/ Munchausen syndrome by proxy)
   Munchausen syndrome by proxy is intentionally producing symptoms in
     someone else who is under one’s care (usually one’s children)
 Commonly feigned symptoms:
   Psychiatric- hallucinations, depression
   Medical- fever (by heating the thermometer), infection, hypoglycemia,
     abdominal pain, seizures and hematuria
                                       86
    The problem is therefore reframed or redefined in such a way that,
     symptoms and their resolution are both legitimized.
    The patient has little choice but to accept and respond to a proposed course
     of action or seek care elsewhere.
IMPLICATIONS
 These patients are willing to undergo incredible hardship:
   Limb amputation
   Organ loss
   Even death to perpetuate the masquerade
 Although multiple hospitalizations often lead to:
   Iatrogenic physical conditions
   Postoperative pain syndromes
   Drug addictions
   Patients continue to crave hospitalization for its own sake
 The patients typically have a fragile and fragmented self-image and are
  susceptible to psychotic and even suicidal episodes.
 Identification of a factitious disorder is usually made in 1 of 4 ways:
   The patient is accidentally discovered in the act
   Incriminating items are found
   Laboratory values suggest non-organic etiology
   The diagnosis is made by exclusion
MALINGERING
 Malingering involves the intentional reporting of physical or psychological
  symptoms in order to achieve personal gain.
 Common external motivations include the avoidance of military conscription
  or duty, avoidance of work, police, receiving room and board, obtaining
  narcotics, and receiving monetary compensation.
 Not that malingering is not considered to be a mental illness.
 It is not uncommon in hospitalized patients.
 Significantly it is commoner in men than women.
CLINICAL FEATURES
 Patients usually present with multiple vague complaints that do not conform
  to a known medical condition.
 They often have a long medical history with many hospital stays.
 They are generally uncooperative and refuse to accept a good prognosis even
  after extensive medical evaluation.
                                       87
 Their symptoms improve once their desired objective is obtained.
 Amnesia is the most common psychological presentation. Followed by
  paranoia, morbid depression, suicidal ideation and psychosis.
 The person exhibits or has a history of antisocial behavior.
 Treatment is not required as this is not a psychiatric condition.
  Somatic symptoms disorders: patients believe they are ill and do not
   intentionally produce or feign symptoms.
  Factitious disorder: patients intentionally produce symptoms of a
   psychological or physical illness because of a desire to assume the sick
   role, not for external rewards.
  Malingering: patients intentionally produce or feign symptoms for
   external rewards.
                                       88
SEXUAL PERVERSIONS AND PARAPHILIAS
 Sexual perversion or paraphilia is a condition in which a person’s sexual
  arousal and gratification depend on fantasizing about and engaging in sexual
  behavior that is atypical and extreme.
 Paraphilias (Sexual deviations, perversions) are disorders of sexual preference
  in which sexual arousal occurs persistently (at least 6 months) and
  significantly in response to objects which are not a part of normal sexual
  arousal
   A paraphilia can revolve around a particular object e.g. nonhuman objects,
     suffering or humiliation of self and/or sexual partner, children or
     nonconsenting person.
   It can be a particular behavior such as inflicting pain, exposing oneself.
 A paraphilia is considered a disorder when it causes distress or threatens to
  harm someone else.
 Paraphilic fantasies alone are not considered disorders unless they are intense,
  recurrent and interfere with daily life, occasional fantasies are considered
  normal components of sexuality (even if unusual).
 Most paraphilic disorders occur almost exclusively in men, but sadism,
  masochism and pedophilia may also occur in women.
 Voyeurism, pedophilia and exhibitionism are the most common paraphilic
  disorders.
 Patients often have more than one paraphilia.
ETIOLOGY
 It is unclear what causes paraphilic disorders to develop.
 Psychoanalysts theorize that an individual with a paraphilia is repeating or
  reverting to a sexual habit that arose early in life.
 Behaviorists suggest that paraphilias begin through a process of conditioning
   Nonsexual objects can become sexually arousing if they are repeatedly
      associated with pleasurable sexual activity.
   Or particular sexual acts (such as peeping, exhibiting, bestiality) that
      provide especially intense erotic pleasure can lead the person to prefer that
      behavior
   In some cases, there seems to be a predisposing factor such as difficulty
      forming person-to-person relationships.
   Behavioral learning models suggest that a child who is the victim or
      observer of inappropriate sexual behaviors may learn to imitate that
      behavior and is later reinforced for it.
                                        89
    Compensation models suggest that these individuals are deprived of
     normal social sexual contacts and thus seek gratification through less
     socially acceptable means.
COMMON PARAPHILIAS
 Common paraphilias include:
   Pedophilia
   Exhibitionism
   Voyeurism/scoptophilia
   Frotteurism
   Fetishism
   Sexual sadism
   Sexual masochism
   Fetishistic transvestism (Transvestic disorder)
   Zoophilia (bestiality)
 Other paraphilas include sexual arousal with urine (urophilia), feces
  (coprophilia), enemas (klismaphilia), corpses (necrophilia), among many
  others.
 Some of the behaviors associated with paraphilia are illegal. Individuals under
  treatment for paraphilic disorder often encounter legal complications
  surrounding their behaviors.
PEDOPHILIA
 Pedophilia is a persistent or recurrent involvement of an adult (age> 16 years)
  and at least 5 years older than the child in sexual activity with prepubertal
  children (age 13 years or younger) either heterosexual or homosexual.
 This may be associated with sexual sadism.
 The pedophilic behavior may be either limited to incest or may spread to
  children outside the family.
 In most civilized societies, pedophilia is a serious offense and the convicted
  pedophiles’ name remains on a sex offenders’ register in order to protect the
  society.
PEDERASTY
 Sexual activity involving a young male.
                                       90
EXHIBITIONISM
 This is a persistent (or recurrent) and significant method of sexual arousal by
  the exposure of one’s genitalia to an unsuspecting stranger.
 This is often followed by masturbation to achieve orgasm.
 The disorder is almost exclusively seen in males, and the ‘unsuspecting
  stranger’ is usually a female (child or adult).
 Two groups are recognized:
   Type 1: Inhibited men who struggle against the urge, feel guilty and expose
      a flaccid penis.
   Type 2: Aggressive men who expose an erect penis and masturbate then or
      later
 Type 2 show an association with actual sexual assaults. Behavioral treatments
  may be beneficial. SSRIs have a limited evidence base.
VOYEURISM/SCOPTOPHILIA
 This is a persistent or recurrent tendency to observe unsuspecting persons
  (usually of the other sex) naked, disrobing or engaged in sexual activity.
 This is often followed by masturbation to achieve orgasm without the
  observed person(s) being aware.
 This is almost always seen in males.
 Watching pornography is not included here.
FROTTEURISM
 This is a persistent or recurrent involvement in the act of touching and rubbing
  against an unsuspecting, nonconsenting person (usually of the other sex).
 Frottage is often employed in crowded places e.g. buses, where the victim
  does not protest because she cannot suspect that frottage can be committed
  there.
 This is often seen in adolescent males.
FETISHISM
 In fetishism, the sexual arousal occurs either solely or predominantly with a
  nonliving object which is usually intimately associated with the human body.
 The word fetish means magical i.e. the non-living object ‘magically’ become
  phallic for that person.
 Fetishism is not diagnosed if the sexual object is the wearing of clothes of
  opposite sex (Fetishistic transvestism), the use of a human body part
  (masturbation), or the use of a genital-stimulating object (e.g. vibrator).
 Fetishism is very often associated with masturbation.
                                       91
 An example of fetishistic disorder is a man being primarily sexually aroused
  by woman’s shoes causing significant distress and marital problems.
SEXUAL SADISM
 In this disorder, the person (the ‘sadist’) is sexually aroused by physical and/or
  psychological humiliation, suffering or injury of the sexual partner (the
  ‘victim’).
 Most often the person inflicting the suffering is male, although this is not
  essential.
 The methods used range from restraining by tying, beating, burning, cutting,
  stabbing, to rape and even killing.
SEXUAL MASOCHISM
 This is just the reverse of sexual sadism.
 Here the person (the ‘masochist’) is sexually aroused by physical and/or
  psychological humiliation, suffering or injury inflicted on self by other
  (usually ‘sadists’).
 Most often the masochist is a female though any pattern is possible.
 The methods used are the same as the ones used in sexual sadism. Only there
  is a role reversal.
 To be called a disorder, this should be persistent and significant mode of
  sexual arousal in the person.
 Sexual sadism and masochism are often seen in the same individual and are
  on a continuum, therefore they are classified together as sadomasochism in
  ICD-10.
FETISHISTIC TRANSVESTISM (TRANSVESTIC DISORDER)
 This disorder occurs exclusively in heterosexual males.
 The person actually or in fantasy wears clothes of the opposite sex (cross-
  dressing) for sexual arousal.
 An example of transvestic disorder is a person being sexually aroused by
  dressing up as a member of the opposite gender. This does not mean they are
  homosexual.
 This disorder should be differentiated from dual-role transvestism and
  transsexualism.
 This disorder may be associated with fantasies of other males approaching the
  person who is in a female dress.
 Masturbation or rarely coitus is associated with cross-dressing to achieve
  orgasm.
                                        92
 To be called a disorder, this should be a persistent and significant mode of
  sexual arousal in the person.
ZOOPHILIA (BESTIALITY)
 Zoophilia as a persistent and significant involvement in sexual activity with
  animals is rare.
 Occasional or situational zoophilia is much more common.
TREATMENT
 Paraphilias are difficult to treat.
 Treatment approaches include: traditional psychoanalysis, hypnosis, behavior
  therapy techniques and drugs.
 Psychoanalysis and psychoanalytic psychotherapy: This is of particular help
  if the patient is psychologically minded and has good ego strength for therapy.
 Behavior therapy: aversion therapy is the treatment choice in severe,
  distressing paraphilia with the patient’s consent.
      o Aversion conditioning: for example, involves using negative stimuli to
          reduce or eliminate a behavior.
               Assisted aversive conditioning is similar to covert sensitization
                 except the negative event is made real, most likely in the form of
                 a foul odor pumped in the air by the therapist.
               The goal is for the patient to associate the deviant behavior with
                 the foul odor and take measures to avoid the odor by avoiding the
                 said behavior.
      o Covert sensitization: entails the patient relaxing, visualizing scenes of
          deviant behavior followed by a negative event, such as getting his penis
          struck in the zipper of his pants.
      o Vicarious sensitization: entails showing videotapes of deviant behavior
          and their consequences, such as victims describing desired revenge or
          perhaps even watching surgical castrations.
      o There are also positive conditioning approaches that might center on
          social skills training and alternate behaviors the patient might take that
          are more appropriate.
      o Reconditioning techniques center on providing immediate feedback to
          the patient so that the behavior will be changed right away.
               For example, a person might be connected to a plethysmographic
                 biofeedback machine that is hooked up to a light. The person is
                 taught to keep the light within a specific range of color while the
                 person is exposed to sexually stimulating material.
                                        93
      o Masturbation training might focus on separating the pleasure inherent
          in masturbation and climax from the deviant behavior.
 Drug therapy:
   Antipsychotics have sometimes been used for severe or dangerous
      aggression associated with paraphilias. Benperidol was earlier believed to
      be particularly useful but the claim has not been substantiated, and the drug
      is not available in the market.
   Antiandrogens (cyproterone acetate or medroxy-progesterone acetate-
      Depo-provera) can be used in paraphilias with excessive sexual activity.
      o This class of drugs drastically lower testosterone levels temporarily.
      o This results in reduction of frequency of erections, sexual fantasies and
          initiation of sexual behaviors including masturbation and intercourse.
      o The drug lowers sex drive in males and can reduce the frequency of
          mental imagery of sexually arousing scenes. This allows for
          concentration on counseling without a strong distraction from the
          paraphilic urges.
      o Note: the level of an individual’s sex drive is not consistently related to
          paraphiliac behavior. Additionally, high levels of circulating
          testosterone do not predispose a male to paraphilias.
      o Increasingly the evidence suggests that combing drug therapy with
          cognitive behavior therapy can be effective.
   Antidepressant such as fluoxetine (Prozac) have also successfully
      decreased sex drive but have not effectively targeted sexual fantasies.
 Cognitive therapy: includes restructuring cognitive distortions and empathy
  training.
   Restructuring cognitive distortions:
      o Involves correcting erroneous beliefs by the patient, which may lead to
          errors in behavior such as seeing victim and constructing erroneous
          logic that the victim deserves to be part of the deviant act.
   Empathy training:
      o Involves helping the offender take on the perspective of the victim and
          better identify with them, in order to understand the harm that has been
          done.
 Other treatment: castration and psychosurgery are extremely rare choices
  these days.
                                        94
SUBSTANCE MISUSE
 A substance is regarded as being misused (or abused) if it produces physical,
  psychological or social harm.
 Substance use disorder is characterized by problematic pattern of use
  (impairment or distress manifested by at least 2 of the following within a year,
  regardless of the substance):
   Using substance more than originally intended
   Persistent desire or unsuccessful efforts to cut down on use
   Significant time spent in obtaining, using or recovering from substance
   Craving to use substance
   Failure to fulfil obligations at work, school or home
   Continued use despite social or interpersonal problems due to the substance
     use
   Decreased social, occupational or recreational activities because of
     substance use
   Use in dangerous situations (e.g. driving a car)
   Continued use despite subsequent physical or psychological problem (e.g.
     drinking alcohol despite worsening liver problems)
   Tolerance
   Withdrawal
 Substance abuse is common in men than women.
 Commonly misused substances include:
   Alcohol
   Prescribed drugs and legal drugs: Benzodiazepines, nicotine, caffeine and
     cannabis
   Opioids: heroin, morphine, pethidine, methadone
   Stimulants: amphetamines, cocaine, ecstasy
   Hallucinogens: LSD, phencyclidine, solvents
 Substance misuse presents in diverse ways for example as depression or
  morbid jealousy (both associated with alcohol), acute psychosis
  (amphetamines) or as hematemesis (alcoholic cirrhosis).
 There are several categories of substance misuse:
   At risk consumption (alcohol) intake at a level associated with increased
     risk of harm.
   Harmful use- misuse associated with health and social consequences but
     without dependence.
   Dependence- prolonged, regular use of some substances (especially
     alcohol, opioids, amphetamines) can lead to dependence (addiction) and
     withdrawal syndromes.
                                       95
     Intoxication-is the acute effect of the substance- being drunk (alcohol),
        tripping (LSD) or stoned (cannabis). Intoxication with illicit drugs may
        lead to acute psychiatric presentations.
   Etiological factors associated with substance misuse are multifactorial and
    include genetic, neurobiological, psychological, socioeconomic and legal
    factors.
   Mood symptoms are common among persons with substance use disorders.
     Note: Substance-induced mood symptoms improve during abstinence,
        whereas primary mood symptoms persist.
   Psychotic symptoms may occur with some substances.
   Personality disorders and psychiatric comorbidities (e.g. major depression,
    anxiety disorders) are common among persons with substance use disorders.
   It is often challenging to decide whether psychiatric symptoms are primary or
    substance induced.
   Withdrawal: the development of a substance-specific syndrome due to the
    cessation (or reduction) of substance use that has been heavy and prolonged.
   Tolerance: the need for increased amounts of the substance to achieve the
    desired effects or diminished effect if using the same amount of the substance.
   Withdrawal symptoms of a drug are usually opposite of its intoxication
    effects. For example, alcohol is sedating, but alcohol withdrawal can lead
    brain excitation and seizures.
   Both the intoxicated and withdrawing patient can present difficulties in
    diagnosis and treatment. Since it is common for persons to abuse several
    substances at once, the clinical presentation is often confusing and
    signs/symptoms may be atypical.
   Treatment of substance use disorders:
     Behavioral counseling should be part of every substance use disorder
        treatment.
     Psychosocial treatments are effective and include:
        o Motivational intervention (MI)
        o Cognitive behavioral therapy (CBT)
        o Contingency management
        o Individual therapy
        o Group therapy
     Twelve-step groups such as Alcoholics anonymous (AA) and Narcotics
        Anonymous (NA) should also be encouraged as part of the treatment.
     Pharmacotherapy is specific for some drugs of abuse.
                                        96
ALCOHOL
 Ethyl alcohol is a natural product of breakdown of carbohydrates in plants.
 Its euphoriant and intoxicating properties have been known from prehistoric
  times.
 There has been an increase in drinking ever since and control measures put in
  place but alcohol is still being consumed.
 In the past, primary prevention of alcohol and drug use was:
   Controlling availability
   Ensuring resistance to individuals by way of education
   Persuasion
   Alternative provision- provision of bars/number of hours etc.
   Laws- 18 years and above/21 years etc.
 Secondary prevention: these are already drinking and the aim is to prevent
  further damage such as disease or social function loss.
 The harm depends on: age, gender, setting, culture, genetic make-up, pattern
  of consumption and amounts in units.
EPIDEMIOLOGY
 1 unit= 8g of ethanol= half a pint of 3.5% alcohol volume bear or a glass of
  125mls, Tot of spirits
 In Spain/Australia 1 drink contains 10g ethanol, in the USA 1 drink contains
  13g ethanol.
                      % 𝑎𝑙𝑐𝑜ℎ𝑜𝑙 ×𝑣𝑜𝑙𝑢𝑚𝑒
 Units of alcohol=
                            1000
 Mosi lager units of alcohol= (4% x 375ml)/1000= 1.5 units
 Prevalence of alcohol related problems equals alcohol consumption per
  person.
 High consumption of alcohol leads to high morbidity (cirrhosis). Less
  sporadic drinking is less harmful than bout/binge drinking patterns.
 Drinking by women has gone up from the 20th century.
 Drinking is high in young age groups.
 Ethnicity and religious minorities have different drinking patterns; Hindus/
  Sikhish/ SDA/ Baptists oppose/prohibit drinking.
 In the US/UK heavy drinkers are among the Indians, Pakistanis.
 Occupations lead to heavy drinking.
   Availability of alcohol at the work place.
   Social expectations (business meetings)
   Separation from normal, social and sexual relationships
                                          97
    High income: doctors, lawyers, senior executives are all among heavy
     consumers.
DEPENDENCY/ADDICTION
 A cluster of physiological, behavioral and cognitive phenomena in which the
  use of a substance or class of substances takes on a higher priority for a given
  individual than other behavior that once had great value.
 According to the ICD for a dependency syndrome to be diagnosed 3 or more
  of the following should be present:
   Strong sense of compulsion to take substance
   Difficulty in controlling substance taking behavior in terms of onset,
      termination or level of use
   A physiological withdrawal state when substance has been ceased or
      reduced
   Evidence of tolerance
   Progressive neglect of alternative pleasure or interests
   Persistent substance use despite clear overtly harmful consequences
EFFECTS OF ALCOHOL
 Alcohol (ethanol) activates gamma-aminobutyric acid (GABA), dopamine
  and serotonin receptors in the CNS and inhibits glutamate receptor activity
  and voltage-gated calcium channels.
   GABA receptors are inhibitory and glutamate receptors are excitatory.
     Thus alcohol is a potent CNS depressant.
 Alcohol is metabolized in the following manner:
   Alcohol acetaldehyde (enzyme: alcohol dehydrogenase)
   Acetaldehyde  acetic acid (enzyme: aldehyde dehydrogenase)
 There is an upregulation of these enzymes in heavy drinkers.
 Secondary to a gene variant, Asians often have less aldehyde dehydrogenase,
  resulting in flushing and nausea, and likely reducing their risk of alcohol use
  disorder.
 Alcohol related social harm involves family relationships, economic factors,
  employment problems, crime, and drunkesnness offences.
                                       98
MANAGEMENT OF ALCOHOL RELATED PROBLEMS
 History: always take a good history inclusive of quantities, problems
  associated, dependence, withdrawal, harm, social history, personal history and
  other drug use.
 Examination- cutaneous and superficial signs
   Spider naevi, talengiectasia, facial mooning, parotid enlargement, palmer
     erytherma, dupytrens contracture, gynecomastia etc.
   Labs- blood tests (MCV increases), U&Es, albumin, LFTs, triglycerides,
     clotting time
 Pharmacotherapy
   This is medication to minimize withdrawal symptoms:
     o Admit after assessment
     o Detoxification
     o Benzodiazepines- Chlordiazepoxide 80-100mg/ day divided doses,
         Diazepam can also be used
     o Chlormethiazole effectively controls withdraw symptoms, however not
         safe for outpatient. Alcohol and Chlormethiazole interaction causes
         death- respiratory depression.
     o Patients are discharged when fits have gone, feed well and confusion is
         gone.
     o Vitamin supplementation can go on for several months.
   Disulfiram: inhibits aldehyde dehydrogenase and leads to accumulation of
     alcohol metabolites i.e. acetaldehyde.
     o Dosage- 200mg-800 mg per day
     o Acetaldehyde accumulates in blood and causes discomfort: flushing,
         headache, nausea, hypotension, labored breath.
                                      99
     o It should be given when alcohol breath test is zero and cannot be given
        to persons with: heart disease, suicidal tendencies, hypotension
        treatment and active liver disease.
   Acamprosate: this is a GABA agonist and Glutamate antagonist
     o More tolerable
     o Dose: 666mg TDS 6/12 or 2g divided doses
     o It causes diarrhea, irregular heartbeat, head aches
     o It is not indicated in patient above 65 years.
   Naltrexone: this is a GABA agonist and glutamate antagonist as well as an
     opiate antagonist
     o It blocks euphoric effects
     o It is not dose dependent
     o This drug limits the amounts one can drink then it gives nausea,
        dizziness, headache, insomnia
   Nelmefene/nelmetrene/silincro: similar effects to naltrexone.
   Antidepressants: fluoxetine, fluvoxamine.
   Note: after detox insomnia is experienced and patients may relapse as such
     give trazedone a GABA agonist and muscle relaxant.
 Psychological management:
   Social skills training
   CBT
   Group therapy
   Co joint and family therapy
   Community and reinforcement
   Approach social network behavioral therapy
   Alcohol advice center
   Employment policies
   Alcoholics anonymous
   Specialized centers.
INTOXICATION
CLINICAL PRESENTATION
 Absorption and elimination rates of alcohol are variable and dependent on
  many factors including age, sex, body weight, chronic nature of use, duration
  of consumption, food in the stomach and the state of nutrition and liver health.
 The effects of ethanol also depend on blood alcohol level (BAL).
   Serum alcohol level or an expired air breathalyzer can determine the extent
      of intoxication.
                                       100
 Effects of alcohol:
   Decreased fine motor control
   Impaired judgement and coordination
   Ataxic gait and poor balance
   Lethargy, difficulty sitting upright, difficulty with memory, nausea/
     vomiting
   Rigidity of thought
   Coma in the novice drinker
   Respiratory depression and death
                                          101
TREATMENT OF INTOXICATION
 History and examination
 Laboratory investigations-
   Serum: blood glucose, urea and electrolytes, LFTs
   Imaging: MRI/CT scan, note any white matter cortical atrophy or
     ventricular enlargement
 Monitor: airway, breathing, circulation.
   Severely intoxicated patient may require mechanical ventilation with
     attention to acid-base balance, temperature and electrolytes while he or she
     is recovering.
 Give thiamine (to prevent Wernicke’s encephalopathy) and folate.
 Naloxone may be necessary to reverse effects of co-ingested opioids.
 Computed tomographic (CT) scan of the head may be necessary to rule out
  subdural hematoma or other brain injury.
 The liver will eventually metabolize alcohol without any other interventions.
 Gastrointestinal evacuation (e.g. gastric lavage, induction of emesis and
  charcoal) is not indicated in the treatment of alcohol (Ethanol) overdose unless
  a significant amount of alcohol was ingested within the preceding 30-60
  minutes.
 Alcohol detoxification- disulfiram (when alcohol breath is zero), acamprosate,
  naltrexone
                                       102
    Delirium tremens is present in 5% of cases
    Onset 24-48 hours after stopping heavy prolonged drinking
    It is characterized by
     o Coarse tremors in the limbs
     o Restlessness
     o Loss of contact with reality: visual hallucination, persecutory and
         paranoid delusions with persecutory
     o Fear and agitation sometimes aggression
     o Delirium and clouding of consciousness with disorientation
     o Seizures
     o Autonomic disturbance (sweating, fever, tachycardia, hypertension)
     o Insomnia
     o Dehydration and electrolyte disturbance
     o Shock
     o Wernicke’s encephalopathy
     o Hypoglycemia
    These symptoms lasts 3-4 days, followed by exhaustion and patchy
     amnesia for the episode
TREATMENT
 Benzodiazepines        (Chlordiazepoxide     [Librium],     diazepam       or
  lorazepam[Ativan]) should be given in sufficient doses to keep the patient
  calm and lightly sedated, then tapered down slowly.
   Carbamazepine or valproic acid can be used in mild withdrawal.
 Antipsychotics (be careful of lowering seizure threshold) and temporary
  restraints for severe agitation.
 Thiamine (vitamin B1), folic acid and a multivitamin to treat nutritional
  deficiencies (“banana bag”).
 Electrolyte and fluid abnormalities must be corrected.
 Monitor withdrawal signs and symptoms with Clinical Institute Withdrawal
  Assessment (CIWA) scale.
 Careful attention must be given to level of consciousness and the possibility
  of trauma should be investigated.
 Check for signs of hepatic failure (e.g. ascites, jaundice, caput medusa,
  coagulopathy).
 Seizure management:
   Admission
   Ensure safety of room
   Dimly lit and well spread lighting
                                     103
      Use benzodiazepines- Clordiazepoxide 100mg-150 mg/ day, Diazepam 50-
       100mg per day orally
       o Titrate benzodiazepine to not more than 14 days
      Parenteral Vitamins-Vitamin B complex
      Haloperidol 10mg/ day
      Balance electrolytes and monitor sugar
      On recovery consider counselling/relative/family etc.
      Long term management
    A 42-year-old man has routine surgery for a knee injury. After 72 hours in
    the hospital he becomes anxious, flushed, diaphoretic, hypertensive and
    tachycardic
    What most likely can account for this patient’s symptoms?
        Alcohol withdrawal
    Treatment?
        Benzodiazepine taper (Chlordiazepoxide [Librium] or Lorazepam
         [Ativan] are considered the drugs of choice)
    What are you most concerned about?
        Seizures, delirium, hypertension and arrhythmias.
METABOLIC COMPLICATIONS
    Include hypoglycemia, alcoholic stupor, acute renal failure.
    Always screen for RFT/DM
    Give dextrose intravenously
    Consider diuresis if completely deranged renal function tests (RFT) with loss
     of consciousness.
                                         104
WERNICKE’S ENCEPHALOPATHY
 An acute encephalopathy presenting with delirium (confusion), ataxia,
  nystagmus and opthalmoplegia occurring in the severely alcohol dependent
  usually in the context of withdrawal.
 Patients dying show hemorrhage in brain stem and thalamus.
 These are associated changes in the peri-aqueduct and ventricular areas.
 It is due to thiamine deficiency (Vitamin B1) and requires urgent treatment.
 It may progress to Korsakoff’s syndrome, which presents with cognitive
  deficits and confabulation.
 Management:
   Admit
   Withdraw alcohol
   Parenteral thiamine urgent- Pabrinex 2-4 ampoules TDS for 3 days then
      daily for 3 days
   Dilute each ampoule in 50-100mls of NS or DNS of 5% and given in 30
      minutes.
   Watch for complications- anaphylactic shock, delirium tremens.
   NB: it is importance to give Pabrinex parenterally to malnourished
      alcoholics for 3 days once or twice even to those that have vomiting and
      diarrhea or intercurrent illness or those with peripheral neuropathy or those
      undergoing detoxification.
   Disturbance of consciousness in alcohol can be caused by traumatic
      subdural hematoma, hypoglycemia, hepatic encephalopathy and dementia.
      They will have initial incontinence, generalized weakness, slurred speech,
      ataxia, cerebellar degeneration (gait and stance ataxia).
GASTROINTESTINAL COMPLICATIONS
 Liver disease- obesity, fatty liver, and cirrhosis
 Alcoholic liver cirrhosis and its associated complications (bleeding disorders)
SEXUAL IMPAIRMENT
   Increased arousal
   Impaired erectile function pharmacologically
   Anxiety after impairment ensure decrease in erection
   Direct toxicity on leydig cells of testis, decrease testosterone, decreased
    spermatogenesis, infertility, testicular atrophy.
                                       105
FOETAL ALCOHOL SYNDROME
 Heavy drinkers have spontaneous abortion.
 Intrauterine growth restriction (IUGR).
 Foetal alcohol syndrome:
   Developmental and growth restriction/retardation
   Facial and neurological abnormalities
   Brain development impairment
   Behavioral difficulties
   NB: antenatal should screen for alcohol use i.e. use of 1-2 drinks per week.
                                       106
DEPRESSION AND ANXIETY
 Alcohol releases inhibitions making it easier to express sadness or self-
  destruction impulse.
 The problems that were overcome/overshadowed during drinking suddenly
  come back especially during hangover.
 Depression due to alcohol is more common in females.
 It is important not to make diagnosis of anxiety in an alcoholic consuming
  person until at least 3 weeks of abstinence since alcohol withdrawal can mimic
  anxiety.
 Manage the anxiety or depression and alcohol use.
                                      107
REVISION
CASE STUDIES
CASE ONE: MR JAMES MPUNDU A RETIRED SOLDIER
Mr James Mpundu male and by his NRC which he carries is 70 years old, a well-
known resident of Kabanana, who has been living in a partially completed
building on the allocated plots of Kabanana.
He is loved by his community for his generosity and good cheer. He usually
dishes out money to whoever asks without counting. He loves singing and would
tell loudly stories of the war of 1945 when he was a young man. He would relish
his story especially to the youth and accompanied by small bottles of scotch
whiskey which he produces from pockets of his green army jacket.
The neighborhood had no knowledge of Mr Mpuundu’s visitors, neither did
anyone know where he came from, he does not talk about that. Since you live in
his neighbourhood, one day you meet him as he sat with his usual youthful friends
and you decide to join in their social chat. He welcomes you as he stares directly
at you and offers you where to sit.
‘Oh welcome great sir, do you also live here in Kabanana?’
And you respond, ‘yes sir’
He continues, ‘you know I don’t think my real name is James but that is what is
written on this document, I look at this document, I don’t think that’s my face.
Do you want something to drink, Whisky?’ You answered, ‘Whisky would be
fine’
He fetched a small bottle from his jacket and offered it to you.
He continues, ‘you know I can’t find sleep until I have found enough of these
bottles, previously I would sleep with just one, now I take four to sleep, at some
point I took too much, maybe six, I passed out, when I looked, I was in hospital,
my neighbor was there for me’. ‘I would do anything to find a good beer.’ I also
noticed of late my urine color had gotten deep yellow and I have difficulties
finding myself in the morning, my hands shake but the moment I drink one bottle,
all is well.”
I have had bad dreams of late and even when am alone, the same dreams and
things happen, a man approaches me and asks me to follow him to heaven, he
tells me he is my uncle, do you believe in heaven sir?”

CASE NINE: A 27 YEAR-OLD YOUNG MALE ADULT
Johanis Milimo is a 27-year-old male living in Avondale Lusaka who recently
moved back in with his parents after his fiancée was killed by a drunk driver 3
months ago. His fiancée, a beautiful young woman he had been dating for the past
4 years, was walking across a busy road intersection in Cairo Road of Lusaka to
meet him for lunch one day. He still vividly remembers the horrific scene as the
drunk driver ran the red light, hitting down his fiancée right before his eyes.
He raced to her side, embracing her crumpled, bloody body as she died in his
arms in the middle of the crosswalk. No matter how hard he tries to forget, he
frequently finds himself reliving the entire incident as if it was happening all over.
Since the accident, Milimo has been plagued with nightmares about the accident
almost every night. He had to quit his job because his office was located in the
building right next to the little café where he was meeting his fiancée for lunch
the day she died. The few times he attempted to return to work were unbearable
for him. He has since avoided that entire area of the Lusaka Town.
Normally an outgoing, fun-loving gentleman, Milimo has become increasingly
withdrawn, “jumpy”, and irritable since his fiancé’s death. He has stopped
working out, playing his guitar, or playing basketball with his friends – all
activities he once really enjoyed. His parents worry about how detached and
emotionally flat he has become.
