III. Etiology
A. Neurotransmitters
1.Serotonin. biogenic amine neurotransmitter. Serotonin depletion occurs in
depression; Some patients with suicidal impulses have low cerebrospinal
fluid (CSF) concentrations of serotonin metabolites (5- hydroxyindole acetic acid [5-
HIAA]) and low concentrations of serotonin uptake sites on platelets.
2. Norepinephrine. Abnormal levels (usually low) of norepinephrine metabolites in
blood, urine, and CSF of depressed patients.
3. Dopamine. Dopamine activity may be reduced in depression and increased in
mania. Drugs that reduce dopamine concentrations (e.g., reserpine [Serpasil]) and
diseases that reduce dopamine concentrations (e.g., Parkinson’s disease) are
associated with depressive symptoms. Drugs that increase dopamine concentrations,
such as tyrosine, amphetamine, and bupropion (Wellbutrin), reduce the symptoms of
depression.
B. Psychosocial
1. Psychoanalytic. Freud described internalized ambivalence toward a
love object (person), which can produce a pathologic form of mourning if the object is
lost or perceived as lost. Mania and elation are viewed as defense against underlying
depression. Rigid superego serves to punish person with feelings of guilt about
unconscious sexual or aggressive impulses.
2. Psychodynamics. In depression, introjection of ambivalently viewed lost objects
leads to an inner sense of conflict, guilt, rage, pain,
3. Cognitive. negative self-view (“things are bad because I’m bad”).
4. Learned helplessness. A theory that attributes depression to a person’s inability to
control events.
5. Stressful life events. Losing a parent before age 11 is the life event most associated
with later development of depression.
V. BipolarDisorder
There are two types of bipolar disorder:
1-bipolar I characterized by the occurrence of manic episodes with or without a major
depressive episode
2-bipolar II characterized by at least one depressive episode with or without a
hypomanic episode.
A. Depression(major depressive episode).
3. Associated features
a. Somatic complaints may mask depression:e.g cardiac,
gastrointestinal, and genitourinary symptoms .
b. Content of delusions and hallucinations, when present, tends to be
congruent with depressed mood;e.g guilt, poverty, Mood-incongruent delusions are
those with content not apparently related to the predominant mood (e.g., thought
insertion, broadcasting,).
4. Age-specific features.
Depression can present differently at different ages.
a. Prepubertal. Somatic complaints, agitation, phobias.
b. Adolescence. Substance abuse, antisocial behaviour .
c. Elderly. Cognitive deficits (memory loss, apathy).
D. Depressivedisorders
Major depressive disorder. Can occur alone or as part of bipolar disorder. When it .1
occurs alone it is also known as unipolar depression. Symptoms must be present for at
.:1least 2 weeks. More common in women than in men by 2

Premenstrual dysphoric disorder. It occurs about 1 week before the onset of menses .6
and is characterised by irritability,emotional , lability, headache, anxiety, and
depression. Somatic symptoms include wight gain breast pain and syncope
VIII. Treatment
.A. Depressive disorders
.Psychopharmacologic .1
.(SSRI) a. selective serotonin reuptake inhibitor
Early transient side effects include anxiety, gastrointestinal upset, and headache.
Educating patients about the self-limited nature of these effects can enhance
.compliance
Sexual dysfunction is often a persistent, common side effect that may respond to a
change in drug or dosage, or adjunctive therapy with an agent such as
.(BuSpar) or buspirone (Wellbutrin) bupropion
SSRIs may aggravate suicidal ideation and can be managed by clonazepam. Insomnia
can be managed with a benzodiazepine, zolpidem , trazodone
b. Bupropion is a noradrenergic, dopaminergic useful for depression marked by
anergy and psychomotor retardation. It is also devoid of sexual side effects. The
.average dose is 150 to 300 mg/day
c. Venlafaxine, desvenlafaxine, and duloxetine are serotonin– norepinephrine
reuptake inhibitors ,venlafaxine is 75 to 375 mg/day, desvenlafaxine is 50 to 100 mg,
.and of duloxetine is 20 to 60 mg/day
d. Mirtazapine has antihistamine, noradrenergic, and serotoninergic
actions. It specifically blocks 5-HT2 and 5-HT3 receptors, At low doses, it can be
highly sedating and cause weight gain. At higher dosages, it becomes more
noradrenergic relative to its antihistamine effects and so a more activating drug.
.Average dose is 15 to 30 mg/day
f. The tricyclics. Side effects include anticholinergic effects in addition to potential
cardiac conduction delay and orthostasis. The secondary amines, such as nortriptyline,
.are often better tolerated than the tertiary amines, such as amitriptyline
g. Augmentation strategies in treatment-resistant or partially responsive patients
.include liothyronine ,lithium, amphetamines, buspirone
h. If symptoms still do not improve, try an MAOI. An MAOI is safe with reasonable
dietary restriction of tyramine-containing substances. MAOIs must not be
administered for 2 to 5 weeks after discontinuation of an SSRI or other serotoninergic
.e.g., 5 weeks for fluoxetine) drugs
j. ECT is useful in refractory major depressive disorder and major depressive episodes
with psychotic features; or when side effects of antidepressant medications must be

Schizophrenia Spectrum and Other Psychotic Disorders
I. Introduction
-Schizophrenia is a group of disorders along a spectrum with heterogeneous etiologies and is
characterized by disturbances in cognition, emotion, perception, thinking, and behavior.
-Schizophrenia is well established as a brain disorder, with structural and functional abnormalities
visible in neuroimaging studies and a genetic component as seen in twin studies.
-The disorder is usually chronic :
a-prodromal phase.
b-an active phase.
c-a residual phase.
-The active phase has symptoms such as hallucinations, delusions, and disorganized thinking.
-The prodromal and residual phases are characterized by attenuated forms of active phase .
II. Epidemiology
A. Incidence and prevalence. In the United States, the lifetime prevalence
of the disease is about 1%, will develop the disorder during his or her lifetime. Worldwide, 2 million
new cases appear each year. In the United States.
B. Gender and age. Equally prevalent between men and women; usually onset is earlier in men. Peak
age of onset between 15 and 35 .
C. Infection and birth season. Persons born in winter are more likely to develop the disease than
those born in spring or summer ,Increased in babies born to
mothers who have influenza during pregnancy.
D. Race and religion. Jews are affected less often than Protestants and
Catholics, and prevalence is higher in non-white populations.
E. Medical and mental illness. Higher mortality rate from accidents and natural causes than in
general population. Leading cause of death in schizophrenic patients is suicide 10% and 40% abuse
drugs and alcohol. The prevalence of diabetes mellitus type II and metabolic abnormalities is higher
and treatment with atypical antipsychotics agent .
F. Socioeconomics. More common among lower rather than higher socioeconomic groups; high
prevalence among recent immigrants .
III. Etiology
- no single factor is considered causative.
- person has specific biologic vulnerability.
- triggered by stress ) schiz symptoms (.
IV. Diagnosis,Signs,andSymptoms :
- Diagnosis is based on observation and description .
-There are no pathognomonic signs or symptoms. According to the fifth edition of the Diagnostic
Statistical Manual of Mental Disorders )DSM-5( at least two of the following five signs or symptoms
must be present for at least 1 month.
)1( Hallucinations; )2( delusions; )3( disorganized speech; )4( disorganized behavior; or )5( negative
symptoms )e.g., flat affect, abulia(.
A. Overall functioning. function declines or fails to achieve the expected level.
B. Thought content. Abnormal )e.g., delusions, ideas of reference, poverty of content(.
C. Form of thought. Illogical )e.g., loosening of associations, incoherence,neologisms, echolalia(.
D. Perception. Distorted )e.g., hallucinations: visual, olfactory, tactile, and, most frequently,
auditory(.
E. Affect.Abnormal)e.g.,flat,blunted,silly,labile,inappropriate(.
F. Sense of self. Impaired )e.g., loss of ego boundaries, gender confusion(.
G. Volition. Altered )e.g., inadequate drive or motivation and marked
ambivalence(.
H. Interpersonal functioning. Impaired )e.g., social withdrawal and
emotional detachment, aggressiveness (.
I. Psychomotor behavior. Abnormal or changed )e.g., agitation vs.
withdrawal, grimacing, posturing, catatonia(.
J. Cognition. Impaired )e.g., concreteness, inattention, impaired
information processing(.
V. Types:
A. Paranoid
1. delusions of persecution or grandeur.
2. Frequent auditory hallucinations.
3. Patients tense, suspicious, guarded, and sometimes hostile or aggressive.
B. Disorganized)hebephrenia(
1. regression to primitive, disinhibited, and chaotic behavior.
2. Incoherence, marked loosening of associations
3. grimacing.
4. usually before age 25.
C. Catatonic
1. disturbance in motor function called waxy flexibility.
2.rigidity,stupor, echopraxia; Workward positions for long periods of time.
3. Purposeless excitement with risk of injury to self or others.
4. Speech echolalia or mutism.
D. Undifferentiated type
1. Prominent delusions, hallucinations, incoherence .
2. Does not meet the criteria for paranoid, catatonic .
E. Residual type
1. Absence of prominent delusions, hallucinations, incoherence .
VII. Pathophysiology
A. Neuropathology. No consistent structural defects; changes noted
include decreased number of neurons, increased gliosis, and disorganization of neuronal architecture.
There is degeneration in the limbic system, especially the amygdala, hippocampus, and the cingulate
cortex. The basal ganglia, including the substantia nigra and dorsolateral prefrontal cortex are also
involved.
B. Brainimaging
1. Computed tomography )CT(. Cortical atrophy in 10% to 35% of
patients; enlargement of the lateral and third ventricle in 10% to 50%.
2. Magnetic resonance imaging )MRI(. Ventricles in MZ twins with schizophrenia are larger than
those of unaffected siblings.
3. Magnetic resonance spectroscopy. Decreased metabolism of the dorsolateral prefrontal cortex.
4. Positron emission tomography )PET(. In some patients, decreased frontal and parietal lobe
metabolism .
5. Cerebral blood flow )CBF(. In some patients, decreased resting levels of frontal blood flow,
increased parietal blood flow, and decreased whole-brain blood flow.
IX. Treatment
Clinical management of the schizophrenic patient may include hospitalization and antipsychotic
medication in addition to psychosocial treatments, such as behavioral, family, group, individual, and
social skills and rehabilitation therapies.
A. Pharmacologic. The antipsychotics include the first-generation dopamine receptor antagonists and
the second-generation agents such as serotonin–dopamine antagonists )SDAs(, such as risperidone
)Risperdal( and clozapine )Clozaril(.
a. First-generation antipsychotics
)also known as typical antipsychotics, or dopamine receptor antagonists( High-potency agents )e.g.,
haloperidol( are more likely to cause extrapyramidal side effects such as akathisia, acute dystonia,
and pseudoparkinsonism. Low- potency agents )e.g., chlorpromazine [Thorazine]( are more sedating,
hypotensive, and anticholinergic. These agents can cause tardive dyskinesia .
First generation:
1-Chlorpromazine tab
2-Fluphenazine Decanoate inj Long active 5-30 mg
3-Trifluoperazine)stelazine(
4-Haloperidol 5-20 mg
b. Second-generation antipsychotics :
Second-generation agents :
1-Aripiprazole )10-30(
2-Clozapine )150-600(
3-Olanzapine )10-30(
4-Quetiapine )300-800(
5-Risperidone )2-8(
)also known as atypical, novel, or SDAs(—the newer-generation antipsychotic drugs that provide
potent 5-HT2 receptor blockade and varying degrees of D2 receptor blockade, these drugs improve
two classes of disabilities: )1( positive symptoms such as hallucinations, delusions, disordered
thought, and agitation, and )2( negative symptoms such as withdrawal, flat affect, poverty of speech,
and cognitive impairment. They cause tardive dyskinesia.
B. Electroconvulsive therapy )ECT(. Can be effective for acute psychosis and catatonic subtype.
Also for refractory positive symptoms .
C. Psychosocial.
1. Behavior therapy. Desired behaviors are positively reinforced by
rewarding them with specific tokens,
2. Group therapy helpful in decreasing social isolation and increasing reality testing.
3. Family therapy. decrease relapse rates
4. Supportive psychotherapy include advice, reassurance, education, modeling .
personality disorder
I. General Introduction
A. Definition. Personality disorder is an enduring pattern of behavior and
inner experiences that deviates significantly from the individual’s cultural standards; is rigidly
pervasive; has an onset in adolescence or early adulthood;
manifests in at least two of the following four areas: cognition, affectivity, interpersonal function, or
impulse control.
B. Classification.
1. Cluster A. The odd and eccentric cluster consists of the paranoid, schizoid, and schizotypal
personality disorder. These disorders involve the use of fantasy and projection and are associated
with a tendency toward psychotic thinking.
2. Cluster B. The dramatic, emotional, and erratic cluster includes the histrionic, narcissistic,
antisocial, and borderline personality disorders. These disorders involve the use of dissociation,
denial, splitting, and acting out.
3. Cluster C. The anxious or fearful cluster includes the avoidant, dependent, and obsessive-
compulsive personality disorders. These disorders involve the use of isolation, passive aggression,
and hypochondriasis.
5. Diagnosis.
poor eye contact.
Their affect is often constricted, aloof,
avoid spontaneous speech,
Habitual pefernce
Lack of hobbies
Abssence of freinds
6. Differential diagnosis
a. Paranoid personality disorder. has a history of aggressive behavior, and projects his or her
feelings onto others.
b. Schizotypal personality disorder. The patient exhibits oddities
and eccentricities of manners, has schizophrenic relatives, and may
not have a successful work history.
Course and prognosis.
course is long lasting, but not necessarily lifelong.
8. Treatment
a. Psychotherapy. Group therpy
b. Pharmacotherapy. Small dosages of antipsychotics, antidepressants, and psychostimulants .
Serotonergic agents may make patients less sensitive to rejection. Benzodiazepines may be of use to
diminish interpersonal anxiety.
C. Schizotypal personality disorder
1. Definition.
characterized by magical thinking, peculiar notations, ideas of reference, illusions, and derealization.
2. Epidemiology
a. Theprevalenceofthisdisorderis3%.
b. The prevalence is increased in families of schizophrenic probands.
3. Etiology.
Etiologic models of schizophrenia may apply.
5. Diagnosis,
oddities of thinking, behavior, and appearance. Taking the history of such patients may be difficult
due to their bizarre way of communicating. These patients may be superstitious or claim powers of
clairvoyance and may believe that they have other special powers of thought and insight. They may
be isolated and have few friends due to their inability to maintain interpersonal relationships and
their inappropriate actions. While under stress, patients may decompensate and show psychotic
symptoms.
Course and prognosis.
Up to 10% of patients commit suicide.
Schizophrenia can develop in some patients. Prognosis is guarded.
8. Treatment
Pharmacotherapy. In dealing with ideas of reference, illusions, and other symptoms, antipsychotic
agents may be useful and can be combined with psychotherapy. Antidepressants may be used when
depression is present. Dramatic,Impulsive,andErraticCluster
A. Antisocial personality disorder
1. Definition.
Persons with antisocial personality disorder are characterized by their inability to conform to the
social norms which govern individual behavior. Such persons are impulsive, egocentric,
irresponsible, and cannot tolerate frustration. Patients with antisocial personality disorder reject
discipline and authority and have an underdeveloped conscience.
2. Epidemiology
a. The prevalence is 3% in men and 1% in women in the general population. .
b. The disorderis more common in lower socioeconomic groups.
d. Predisposing conditions include attention-deficit/hyperactivity disorder )ADHD( and conduct
disorder.
3. Etiology
a. genetic factors .
b. Brain damage or dysfunction
c. Histories of parental abandonment or abuse
5. Diagnosis.
hostility, irritability, and rage. A stress interview, one where patients are vigorously confronted with
inconsistencies in their histories, may be needed to reveal the pathology. A diagnostic workup should
include a thorough neurologic examination. Patients often show abnormal
electroencephalogram )EEG(results and soft neurologic signs suggestive of minimal brain damage in
childhood. Typical experiences beginning in childhood include lying, truancy, running away from
home, thefts, fights, substance abuse, and illegal activities. Promiscuity, spouse abuse, child abuse,
and drunk driving are common. Patients lack remorse for their actions and appear to lack a
conscience.
6. Differentialdiagnosis
a. Substance use disorders. The patient may exhibit antisocial
behavior as a consequence of substance abuse and dependence.
c. Mental retardation. The patient may demonstrate antisocial
behavior as a consequence of impaired intellect and judgment.
d. Psychoses. The patient may engage in antisocial behavior as a
consequence of psychotic delusions.
e. Adhd cognitive difficultis impulse dyscontrol are present
7. Course and prognosis. The condition often significantly improves after early or middle adulthood.
Complications include death by violence, substance abuse, suicide, physical injury, legal and
financial difficulties, and depressive disorders.
8. Treatment
a. Psychotherapy.
b. Pharmacotherapy. Pharmacotherapy is used to deal with symptoms such as anxiety, anger, and
depression, but drugs must be used judiciously due to the risk of substance abuse. If the patient
exhibits evidence of ADHD, psychostimulants such as methylphenidate )Ritalin( may be useful.
B. Border line personality disorder
1. Definition.
Patients with borderline personality disorder are literally
on the border between neurosis and psychosis. They exhibit extraordinarily unstable mood, affect,
behavior, object relations, and self-image. Suicide attempts and acts of self-mutilation are common
occurrences among borderline patients. These individuals are very impulsive, and suffer from
identity problems as well as feelings of emptiness and boredom. Borderline personality disorder has
also been called ambulatory schizophrenia,
2. Epidemiology
a. The prevalence of borderline personality disorder is about 2%
b. Itismorecommoninwomenthaninmen.
c. Of these patients, 90% have one other psychiatric diagnosis, and 40% have two.
d. The disorder is five times more common among relatives , borderline personality disorder is
increased in the mothers of borderline patients.
3. Etiology
a. Brain damage may be present and represent perinatal brain injury,
encephalitis, head injury, and other brain disorders.
b. Histories of physical and sexual abuse, abandonment,
5. Diagnosis.
Patients with borderline personality disorder are marked by their pervasive and excessive instability
of affects, self-image, and interpersonal relationships and their distinct impulsivity. They tend to
have micropsychotic episodes, often with paranoia or transient dissociative symptoms. Self-
destructive, self-mutilating, or suicidal gestures, threats, or acts occur frequently.
6. Differential diagnosis
a. Psychoticdisorder.Impairedrealitytestingpersists.
b. Mood disorders. sustained episodes of depression,
c. Personality change secondary to a general medical condition.
Results of testing for medical illness are positive.
d. Schizotypal personality disorder. The affective features are less
severe.
e. Antisocial personality disorder. The defects in conscience and
attachment ability are more severe.
f. Histrionic personality disorder. Suicide and self-mutilation are
less common. The patient tends to have more stable interpersonal
relationships.
g. Narcissistic personality disorder. Identity formation is more
stable.
h. Dependentpersonalitydisorder.Attachmentsarestable.
i. Paranoid personality disorder. Suspiciousness is more extreme and consistent.
Course and prognosis. .7
; some improvement may occur in later years. Suicide, self-injury, mood disorders, somatoform .8
disorders, psychoses, substance abuse, and sexual disorders are possible complications.
8. Treatment.
a. Psychotherapy. Behavior therapy may be useful to control impulses and angry outbursts and to
reduce sensitivity to criticism and rejection. Social skills training is useful to improve their
interpersonal behavior. Dialectical behavior therapy may be used in cases of parasuicidal behavior
such as frequent cutting.
b. Pharmacotherapy. Antipsychotics are useful in controlling anger, hostility, and brief psychotic
episodes. Antidepressants are useful in improving depressed mood. Monoamine oxidase
inhibitors )MAOIs( may be effective in modulating impulse behavior. Benzodiazepines, particularly
alprazolam )Xanax(, can be helpful with anxiety .
C. Histrionic personality disorder
1. Definition.
Characterized by the flamboyant, dramatic, excitable and
overreactive behavior, persons with histrionic person personality disorder are intent on gaining
attention. They tend to be immature, dependent, and are often seductive.
2. Epidemiology
a. The prevalence of histrionic personality disorder is 2% to 3%.
b. The prevalence is greater in women than in men,
c. This disorder may be associated with somatization disorder, mood
disorders, and alcohol use.
3. Etiology
a. Early interpersonal difficulties may have been resolved by
dramatic behavior.
b. Distant or stern father with aseductive mother may be apattern.
4. Psychodynamics
a. Fantasy in “playing a role,” with emotionality and a dramatic style,
b. Fixation at the early genital level
c. Fear of sexuality, despite overt seductiveness.
Diagnosis.
Patients with histrionic personality disorder are often cooperative and eager to be helped. Gestures .5
and dramatic punctuation in their conversation are common and their language is colorful. Cognitive
test results are usually normal; however, a lack of perseverance may be shown on arithmetic or
concentration tasks. Emotionality may also be shallow or insincere and patients may be forgetful of
affect-laden material. They tend to exaggerate thoughts and feelings to get attention,
IV. Anxiousor Fearful Cluster
A. Obsessive- compulsive personality disorder
1. Definition.
Characterized by perfectionism, orderliness, inflexibility, stubbornness, emotional constriction, and
indecisiveness. Also called anancastic personality disorder.
2. Epidemiology
a. The prevalence is 1% in the general population
b. The prevalence is greater in men than in women.
c. Familialtransmissionislikely.
d. Theconcordanceisincreasedinmonozygotictwins.
3. Etiology.
Patients may have backgrounds characterized by harsh
discipline.
Diagnosis .6
. Patients with obsessive-compulsive personality disorder have a stiff, formal, and rigid demeanor. .7
In an interview, patients may be anxious about not being in control and their answers to questions are
unusually detailed.
B. Avoidance personality disorder
1. Definition.
Patients have a shy or timid personality and show an intense sensitivity to rejection. They are not
asocial and show a great desire for companionship; however, they have a strong need for reassurance
and a guarantee of uncritical acceptance. They are sometimes described as having an inferiority
complex.

5. Nystagmus
6. Impairment in attention or memory
7. Stupor or coma
8. Double vision
F. Withdrawal:-
A substance-specific syndrome that occurs after stopping or reducing the amount of the drug or
substance that has been used regularly over a prolonged period of time. The syndrome is
characterized by physiologic signs and symptoms in addition to psychological changes such as
disturbances in thinking, feeling, and behavior.
Diagnosis of Substance Withdrawal:-
1. Substance-specific syndrome develops after stopping or decreasing prolonged use
2. Syndrome leads to impaired functioning.
3. Not caused by a known general medical condition
G. Tolerance.:-
Phenomenon in which, after repeated administration, a given dose of a drug produces a decreased
effect or increasingly larger doses must be administered to obtain the effect observed with the
original dose.
IV. Specific Substance-Related Disorders:-
A. Alcohol-related disorders:-
the disorders associated with alcoholism generally can be divided into three groups: )1( disorders
related to the direct effects of alcohol on the brain )intoxication, withdrawal, withdrawal delirium,
and hallucinosis(
)2( disorders related to behavior associated with alcohol ) )alcohol abuse and dependence(
)3( disorders with persisting effects )persisting amnestic disorder, dementia, Wernicke’s
encephalopathy, and Korsakoff’s syndrome(
6. Diagnosis,signs,andsymptoms:-
a. Alcohol dependence:-
. Tolerance is a phenomenon in the drinker, who with time requires greater amounts of alcohol to
obtain the same effect. The development of tolerance, especially marked tolerance, usually indicates
dependence.
b. Alcohol abuse:-
Chronic use of alcohol that leads to dependence, tolerance, or withdrawal.
C. Alcohol intoxication:-
1. Definition:-
Alcohol intoxication, also called simple drunkenness, is the recent ingestion of a sufficient amount of
alcohol to produce acute maladaptive behavioral changes.
2. Diagnosis, signs, and symptoms:-
-Whereas mild intoxication may produce a relaxed, talkative, euphoric, or disinhibited person,
-severe intoxication often leads to more maladaptive changes, such a aggressiveness, irritability,
labile mood, impaired judgment, and impaired social or work functioning, among others.
-Persons exhibit at least one of the following: slurred speech, incoordination, unsteady gait,
nystagmus, memory impairment, stupor. Severe intoxication can lead to withdrawn behavior,
psychomotor retardation, blackouts, and eventually obtundation, coma, and death.
-Common complications of alcohol intoxication include motor vehicle accidents, head injury, rib
fracture, criminal acts, homicide, and suicide.
4. Treatment:-
a. Usually only supportive.
b. May give nutrients)especially thiamine,vitaminB12,folate(.
c. Observation for complications )e.g., combativeness, coma, head injury, falling( may be required.
d. Alcoholic idiosyncratic intoxication is a medical emergency that requires steps to prevent the
patient from harming others or self. Lorazepam )Ativan( 1 to 2 mg by mouth or intramuscularly or
haloperidol )2 to 5 mg by mouth or intramuscularly( can be used for agitation. Physical restraints
may be necessary.
Alcohol withdrawal:-
. Begins within several hours after cessation of, or reduction in, prolonged )at least days( heavy
alcohol consumption. At least two of the following must be present: autonomic hyperactivity, hand
tremor, insomnia, nausea or vomiting, transient illusions or hallucinations, anxiety, grand mal
seizures, and psychomotor agitation.
F. Alcohol withdrawal delirium )delirium tremens :-
Usually occurs only after recent cessation of or reduction in severe, heavy alcohol use in medically
compromised patients with a long history of dependence.
2. Medical workup:-
a. Complete history and physical.
b. Laboratory tests—complete blood cell count with differential;
measurement of electrolytes, including calcium and magnesium; blood chemistry panel; liver
function tests; measurement of bilirubin, blood urea nitrogen, creatinine, fasting glucose,
Treatment:-
a. Take vital signs every 6hours.
b. Observe the patient constantly.
c. Decrease stimulation.
d. Correct electrolyte imbalances
e. If the patient is dehydrated,hydrate.
f. Chlordiazepoxide )Librium(: 25 to 100 mg orally every 6 hours
in the geriatric patient, lorazepam )Ativan( 1 to 2 mg by mouth, intravenously, or intramuscularly
every 4 hours
g. Thiamine:100mg orally one to three times a day.
h. Folicacid
i. multivitamin
j. Magnesium sulfate: 1 g intramuscularly every 6 hours for 2 days
I.antipsychotics
Alcohol-induced persisting amnestic disorder:-
1. Wernicke’s encephalopathy:-)also known as alcoholic encephalopathy(.
-An acute syndrome caused by thiamine deficiency. Characterized by nystagmus, abducens and
conjugate gaze palsies, ataxia, and global confusion. Other symptoms may include confabulation,
lethargy, indifference, mild delirium, anxious insomnia, and fear of the dark.
-Treat with 100 to 300 mg of thiamine per day until ophthalmoplegia resolves.
-The syndrome may clear in a few days or weeks or progress to Korsakoff’s syndrome.
2. Korsakoff’s syndrome )also known as Korsakoff’s psychosis(:-
-A chronic condition, Characterized by retrograde and anterograde amnesia. The patient also often
exhibits confabulation, disorientation, and polyneuritis.
In addition Twenty-five percent of patients recover fully, and 50% recover partially with long-term
oral administration of 50 to 100 mg of thiamine per day
Stimulant-related disorders:-
-Amphetamines and amphetamine-like substances effect by releasing catecholamines, primarily
dopamine, from presynaptic stores, from the ventral tegmentum to the cortex and the limbic areas.
Legitimate indications include attention-deficit disorders, and narcolepsy, but are also used in the
treatment of obesity, dementia, fibromyalgia, and depression.
-Methylphenidate )Ritalin( less addictive than other amphetamines, possibly because it has a
different mechanism of action )inhibits dopamine reuptake(.
-Amphetamines are usually taken orally a less rapid euphoria and consequently is less addictive
Amphetamines can induce a paranoid psychosis similar to paranoid schizophrenia.
-Intoxication usually resolves in 24 to 48 hours. Amphetamine abuse can cause severe hypertension,
cerebrovascular disease, and myocardial infarction and ischemia
-Neurologic symptoms range from twitching to tetany to seizures, coma, and death as doses escalate.
Tremor, ataxia, bruxism, shortness of breath, headache, fever, and flushing are common but less
severe physical effects.
2. Drugs:-
a. Major amphetamines:Amphetamine, dextroamphetamine
)Dexedrine(, methamphetamine )Desoxyn, “speed†(, and methylphenidate )Ritalin(.
b. Related substances:-. Ephedrine, phenylpropanolamine )PPA(, khat, and methcathinone
)“crank†(.
c. Substituted )designer( amphetamines )also classified as
hallucinogens(. These have neurochemical effects on both serotonergic and dopaminergic systems
D.Ice:-Pure form of methamphetamine )inhaled, smoked, or injected(
Diagnostic Criteria for Stimulant Intoxication:- A. Behavioral and physical signs and symptoms of
stimulant use. B. Characteristic effects of elation and euphoria. C. Perceived improvement in mental
and physical tasks. D. Agitation and irritability.
E. Dangerous sexual behavior and. aggression.
F. Tachycardia, hypertension, andmydriasis.
Stimulant intoxication delirium:-
In general, result from high doses and sustained use.
c. Stimulant-induced psychotic disorder. Presence of paranoid delusions and hallucinations.
Formication )sensation of bugs crawling under the skin(
d. Stimulant-induced mood disorder. This includes the stimulant- induced bipolar and depressive
disorders.
e. Stimulant-induced anxiety disorder.
g. Stimulant-induced sexual dysfunction. Amphetamines can be used to reverse sexual side effects of
serotonergic agents like fluoxetine )Prozac(. They are often misused to enhance sexual experience
and high and long-term use may lead to erectile and sexual dysfunction
4. Treatment. Symptomatic. Benzodiazepines for agitation. Fluoxetine )Prozac( or bupropion
)Wellbutrin( has been used for maintenance therapy after detoxification.
Cannabis-related disorders:-
Cannabis is the most widely used illegal drug in the world, with an estimated 19 million users in
2012. Cannabis sativa is a plant from which cannabis or marijuana is derived. All parts of the plant
contain psychoactive cannabinoids of which Δ-9- tetrahydrocannabinol )THC( is the main active
euphoriant )many other active cannabinoids are probably responsible for the other varied effects(.
Sometimes, purified THC also is abused. Cannabinoids usually are smoked but also can be eaten
a. Cannabis use disorder:-
. People who use cannabis daily over weeks to months are most likely to become dependent.
b. Cannabis intoxication:-
When cannabis is smoked, euphoric effects appear within minutes, peak in 30 minutes, and last 2 to
4 hours. Motor and cognitive effects can last 5 to 12 hours. -Symptoms include euphoria or
dysphoria, anxiety, suspiciousness, inappropriate laughter, time distortion, social withdrawal,
impaired judgment, and the following objective signs:
1(conjunctival injection, increased appetite, dry mouth, and tachycardia. It also causes a dose-
dependent hypothermia and mild sedation. Often used with alcohol, cocaine, and other drugs. Can
cause depersonalization and, rarely, hallucinations. More commonly causes mild persecutory
delusions, which seldom require medication. In very high doses, can cause mild delirium with panic
symptoms or a prolonged cannabis psychosis )may last up to 6 weeks(. Long-term use can lead to
anxiety or depression
. Chronic respiratory disease and lung cancer are long-term risks secondary to inhalation of
carcinogenic hydrocarbons. Results of urinary testing for THC are positive for up to 4 weeks after
intoxication.
c. Cannabis intoxication delirium:-It is characterized by marked impairment on cognition and
performance tasks.
d. Cannabis withdrawal:-Cessation of daily cannabis use results in withdrawal symptoms within 1 to
2 weeks of cessation. These include irritability, nervousness, anxiety, insomnia, disturbed or vivid
dreaming, decreased appetite, weight loss, depressed mood, restlessness, headache, chills, stomach
pain, sweating, and tremors.
e. Cannabis-induced psychotic disorder:-Cannabis-induced psychotic disorder is rare; transient
paranoid ideation is more common.
f. Cannabis-induced anxiety disorder:-. This disorder is a common diagnosis for acute cannabis
intoxication.
4. Treatment:-
-Treatment abstinence and support.
-Treatment of intoxication usually is not required.
-Anxiolytics may be useful for anxiety
-antipsychotics for hallucinations or delusion
Obsessive Compulsive Of Related Disorder
1)Obsessive Compulsive Disorder:-
*represented by a diverse group of symptoms
* includes:-
A(intrusive thoughts B(rituals. C( preoccupations. D(compulsions
*Obsession is a recurrent and intrusive thought, feeling, idea, or sensation.
*Compulsion is a conscious recurrent behavior, such as counting checking, or avoiding.
A)Epidemiology:-
*Life time prevalence 1-3%
*fourth most common psychiatric diagnosis
*men to woman1:1
*boys are more common than girls
*The mean age of onset is about 20 years
B)Etiology:-
a.Neurotransmitters:-
support the hypothesis that dysregulation of serotonin
b. Brain-imagingstudies:-
increased activity in the frontal lobes, the basal ganglia and the cingulum of patients with OCD.
*)CT(& )MRI( studies have found bilaterally smaller caudates in patients with OCD.
c. Genetics:-
High in ralative with OCD than control probands
C)Psychsocial Factors:-
OCD differs from Obsessive Compulsive Personality which is concern for details, perfectionism
D)Diagnosis and clinical features:-
*Sign and symptoms:-
1(Must have obsessions, compulsions, or both.
2(Obsessions are thoughts or urges that are so pervasive and undesirable they prompt some
suppressive thought or action
3(Compulsions are behaviors that an individual feels he or she must perform in a particular manner
to reduce stress
*OCD symptoms in adult:
A(Contamination:- obsession of contamination followed by washing or avoidance
B( pathological doubt:-obsession and doubt followed by compulsion of checking
C( Intrusive thought:-there are intrusive obsessional thought without compulsion e.g suicidal idea
D(Symmetry:-symmetry or precision lead to compulsionof slowness)pts:take hours to eat meal and
shave their face(
E( Other symptoms:-compulsive hair pulling and nail biting are behavioral patterns related to
OCD )masturbation may also be compulsive(
E)Differential Diagnosis:-
1.Medical condition:-
OCD frequently develops before age 30 years, and new-onset OCD in an older individual should
raise questions about potential neurologic contributions and basal ganglia diseases, such as
Sydenham’s chorea and Huntington’s disease
2. Tourette’s disorder:-
About 90% of persons with Tourette’s disorder have compulsive symptoms
3. Other psychiatric conditions
OCD resemblance to obsessive–compulsive personality disorder
Psychotic symptoms :-often lead to obsessive thoughts and compulsive behaviors.
4.Course and prognosis:-
More than half of patients with OCD have a sudden onset of symptoms. 50% to 70% occurs after a
stressful event, such as a pregnancy, a sexual problem, or the death of a relative.
The course is usually long but variable; some patients experience a fluctuating course, and others
experience a constant one.
*SUICIDE IS RISK FOR OCD pt
F) Treatment:-
1. Pharmacotherapy
Initial effects are generally seen after 4 to 6 weeks of treatment, although 8 to 16 weeks are usually
needed to obtain maximal therapeutic benefit.
**** )SSRI( or clomipramine
A. Selectiveserotoninreuptakeinhibitors
1(fluoxetine )Prozac(, 2(fluvoxamine 3(paroxetine 4(sertraline 5(citalopram
-Higher dosages have often been necessary for a beneficial effect, such as 80 mg a day of fluoxetine.
-SSRIs can cause sleep disturbance, nausea and diarrhea, headache.
-these adverse effects are often transient
B. Clomipramine
-Of all the tricyclic and tetracyclic drugs, clomipramine is the most selective for serotonin reuptake
versus norepinephrine reuptake.
-Dose must be titrated upward over 2 to 3 weeks to avoid gastrointestinal adverse effects and
orthostatic hypotension.
c. Otherdrugs
1(clomipramine or an SSRI:- unsuccessful, many therapists augment the first drug by the addition
of :-
1(valproate 2(lithium 3(carbamazepine )Tegretol(
4(atypical antipsychotic such as risperidone
2. Behaviortherapy
Desensitization, thought-stopping, flooding.
3. Othertherapies
Family therapy reduce marital discord resulting from the disorder
group therapy For extreme cases, electroconvulsive therapy
Other Specified Obsessive Compulsive or Related Disorder:-
A. Olfactoryreferencesyndrome
Olfactory reference syndrome is characterized by a false belief by the patient that he or she has a foul
body odor that is not perceived by others. The preoccupation leads to repetitive behaviors such as
washing the body or changing clothes
B. Body dysmorphic disorder:-
1. Definition:-Imagined belief )not of delusional proportions( that a
defect in the appearance of all or a part of the body is present.
2. Epidemiology:-Onset from adolescence through early adulthood.
*Men and women are affected equally.
3. Etiology:-Unknown
4.Diagnosis, signs, and symptoms:-Patient complain)e.g., wrinkles, hair loss, small breasts or penis,
age spots, stature(.
-Complaint is out of proportion to objective abnormality. If a slight physical anomaly is present, the
person’s concern is grossly excessive.
5.Differential diagnosis:-Distorted body image can also occur in schizophrenia, mood disorders,
anorexia nervosa, OCD, gender identity disorder.
6.Course and prognosis:-Chronic course with repeated visits to doctors, plastic surgeons, or
dermatologists. Secondary depression may occur.
-In some cases, imagined body distortion progresses to delusional belief.
7.Treatment:-
a. Pharmacologic:-Serotoninergic drugs )e.g., fluoxetine ,clomipramine )effectively reduce
symptoms in at least 50% of pts(
b. Psychological
Hair-PullingDisorder(Trichotillomania)
a chronic disorder characterized by repetitive hair pulling that leads to variable hair loss
-The lifetime prevalence ranges from 0.6% to as high as 3.4% in general population
-A childhood type of hair-pulling disorder occurs approximately equally in girls and boys.
Excoriation(Skin-Picking)Disorder
characterized by the compulsive and repetitive picking of the skin.
-It can lead to severe tissue damage
. It was also known , emotional excoriation, epidermotillomania

-Other common sites are legs, arms, hands, fingers, and scalp.
-Many report picking as a means to relieve stress, tension, and other negative feelings
-15% report suicidal ideation due to their behavior and about 12% have attempted suicide
Treatment:-
SSRIs. fluoxetine )Prozac( , naltrexone , lamotrigine )Lamictal( ,CBT)Cogentive Behavior Therapy
Psychopharmacological Treatment
V. Antipsychotic Drugs:-
These are classified into first-generation )conventional( antipsychotics or second-generation
antipsychotics )SDAs, novel or atypical( antipsychotics. Historically, conventional antipsychotics
were efficacious for treating the positive symptoms of schizophrenia with worsening of negative,
cognitive, and mood symptoms. Atypical antipsychotics have been suggested to show improvement
in )1( positive symptoms such as hallucinations, delusions,disordered thoughts, and agitation and )2(
negative symptoms such as withdrawal, flat affect, anhedonia, poverty of speech, catatonia, and
cognitive impairment
Second-generation antipsychotic drugs )SDAs, atypical antipsychotic drugs(:-
-include risperidone )Risperdal(, risperidone consta olanzapine, quetiapine ,ziprasidone,aripiprazole
)Abilify(, paliperidone )Invega(, and clozapine.
-lower risk of extrapyramidal symptoms and eliminate the need for anticholinergic drugs. Second-
generation drugs are also effective for the treatment of bipolar disorder and mood disorders with
psychotic or manic features. A few are also approved for the treatment of bipolar depression, major
depressive disorder )MDD(, and will also have an indication in generalized anxiety disorder.
1. Pharmacologic actions:-
a. Risperidone:-About 80% of risperidone is absorbed from the GI tract, and the combined half-life
of risperidone averages 20 hours
so that it is effective in once-daily dosing.
b. Olanzapine:-Approximately 85% of olanzapine is absorbed from the GI tract, and its half-life
averages 30 hours.in a once daily dose
e. Clozapine:-Clozapine is absorbed from the GI tract. Its half-life is 10 to 16 hours and is taken
twice daily.
f. Aripiprazole:-It has a long half-life of about 75 hours and can be given as a single daily dose.
g. Paliperidone:-Paliperidone has a peak plasma concentration of approximately 24 hours after
dosing.
*Sustenna( reaches higher concentration in the deltoid muscle with a half-life of 25 to 49 days.
*Trinza( has even longer duration of action and is given once every 3 months.
a. Baseline monitoring:-
)1( Personal and family history of obesity, diabetes, dyslipidemia,
hypertension, and cardiovascular disease.
)2( Weight and height
)3( Waist circumference
)4( Blood pressure.
)5( Fasting plasma glucose.
)6( Fasting lipid profile.
Clozapine risk evaluation and mitigation strategy)REMS(:-
-Patients will be monitored for neutropenia using the absolute neutrophil count )ANC( and WBC.
-Treatment will be interrupted if the ANC drops below 1,000 cells/μL
-During the first 6 months, weekly ANC counts are indicated to monitor for the development of
agranulocytosis. If the ANC count remains normal, the frequency of testing can be decreased to
every 2 weeks.Patients exhibiting symptoms of chest pain, shortness of breath, fever, or tachypnea
should be immediately evaluated for myocarditis or cardiomyopathy, an infrequent but serious
adverse effect ending in death. Serial CPK-MB )creatine phosphokinase with myocardial band
fractions(, troponin levels, and EKG studies are recommended, with immediate discontinuation of
clozapine.
All second-generation drugs:-
)1( Neuroleptic malignant syndrome:-
-The development of neuroleptic malignant syndrome is considerably rare with second-generation
drugs than with dopamine receptor antagonists. This syndrome consists of muscular rigidity, fever,
dystonia, akinesia, mutism, oscillation between obtundation and agitation, diaphoresis, dysphagia,
tremor, incontinence, labile blood pressure, leukocytosis, and elevated creatine phosphokinase.
Clozapine, especially if combined with lithium, and risperidone have been associated with
neuroleptic malignant syndrome.
)2( Tardive dyskinesias:-
Second-generation drugs are significantly less likely than dopamine receptor antagonists to be
associated with treatment-emergent tardive dyskinesias.
Dopamine receptor antagonists:-
The dopamine receptor antagonists are presently second-line agents for the treatment of
schizophrenia and other psychotic disorders. Because of their immediate calming effects, however,
dopamine receptor antagonists are often used for the management of acute psychotic episodes
Antidepressants:-
a. Pharmacokinetics:-
-All SSRIs are well absorbed after oral administration and reach their peak concentrations in 4 to 8
hours.
-Fluoxetine has the longest half-life, 2 to 3 days.
-The half-life of sertraline is 26 hours.
- citalopram )2-3days(and escitalopram)35hours(, fluvoxamine. )15hours(
B.Pharmacodynamics:-
The clinical benefits of SSRIs are attributed to the relatively selective inhibition of serotonin
reuptake, with little effect on the reuptake of norepinephrine and dopamine.
1( Choice of drug.:-
-. A number of reports indicate that more than 50% of people who respond poorly to one SSRI will
respond favorably to another.
)2( Comparison with tricyclic antidepressants:-
-Some degree of nervousness or agitation, sleep disturbances, GI symptoms, and perhaps sexual
adverse effects are more common in persons treated with SSRIs than in those treated with tricyclic
drugs.
b. Suicide:-
-SSRIs reduce the risk. Some persons become especially anxious and agitated when given fluoxetine.
The appearance of these symptoms in a suicidal person could conceivably aggravate the seriousness
of their suicidal ideation.
c. Depression during and after pregnancy:-
The use of fluoxetine during pregnancy is not associated with increases in perinatal complications,
congenital fetal anomalies, learning disabilities, language delays, or specific behavioral problems.
Emerging data for sertraline, paroxetine, and fluvoxamine indicate that these agents are probably
similarly safe when taken during pregnancy.
d. Depression in the elderly and medically ill:-
All SSRIs are useful for elderly.
e. Chronic depression:-
Because discontinuation of SSRIs within 6 months after a depressive episode is associated with a
high rate of relapse, a person with chronic depression should remain on SSRI therapy for several
years.
Premenstrual dysphoric disorder:-
-SSRIs reduce the debilitating mood and behavioral changes that occur in the week preceding
menstruation in women with premenstrual dysphoric disorder. Scheduled administration of SSRIs
either throughout the cycle or only during the luteal phase )the 2-week period between ovulation and
menstruation(.
