TRAUMA AND THE BRAIN 2
Trauma and the Brain
The brain has a significant role in enhancing positive aspects of people's development.
Trauma is likely to affect the brain, which may later affect cognitive functions. Traumatic events
may lead to stress, which may lead to other health problems. These effects may affect how an
individual is interacting with each other in the society. The productivity and performance of
people are also affected because of traumatic stress. Stress can affect brain functions, which is
directly linked to how people think. The normal development of the brain is affected when an
individual experiences traumatic events. Adverse events may be experienced when the traumatic
stressors are prolonged. This essay will critically discuss trauma and the brain.
Development of the Brain
Brain development continues from childhood to adulthood, where critical aspects change.
The bulk of brain development happens in the utero development and may continues after birth
(Bremner, 2006),. Ttherefore, the mother must plays a critical role in the development of the
brain. The first five years of life are essential because the brain volume expands (Bremner,
2006). The expansion of the brain may vary in different people based on their personal
characteristics. Human brain development starts in the third gestation week with the
differentiation of the neural progenitor cells (Stiles & Jernigan, 2010). These processes may
continue throughout the adolescent life or even the rest of life. However, the early stages are
critical, and an individual should embrace aspects that are not stressful. This may help overcome
TRAUMA AND THE BRAIN 3
adverse outcomes likely to be experienced when an individual faces traumatic events.
The brain structures are affected by trauma, which may later affect the learning process.
Early adversity affects the nucleus accumbens and inhibits the prefrontal cortex, which critical
for impulse control and executionof the function (Harris, 2014). The prefrontal cortex is a brain
area that is critical for learning, and disturbances may affect memory. Therefore, children may
experience challenges in schools because of past traumatic events. High doses of childhood
trauma may affect the amygdala, the brain's fear response center (Harris, 2014). Therefore,
individuals who experience trauma in childhood are likely to engage in risk behaviors. The
behaviors may lead to adverse impacts on their health.
The environment affects brain development because it influences how an individual
thinks. Stiles and Jernigan (2010) argued that alteration of gene expression and environment
affects neural outcomes. Therefore, the environment should be conducive to ensure positive
results are achieved in healthcare settings. Cortical and subcortical brain structures develop in
fetal development and at the end of the gestation period (Stiles & Jernigan, 2010). The authors
further argued that the major gray and white matter compartments continue to develop from
childhood to adolescence. The environment may affect how an individual behaves and relate
with each other. The social aspects of people influence the environmental influences where some
critical aspects may be adjusted.
Adolescent Brain Development
Adolescents are likely to face challenges that affect the development of the brain. The
challenges they face may lead to traumatic stress, which may influence their behavior. Cerebral
TRAUMA AND THE BRAIN 4
transformation occurs during adolescents and may be affected by the environment
(Balvin&Banati, 2017). However, many adolescents are likely to engage in risky activities and
are vulnerable to problematic activities. Some of these aspects are likely to affect how an
individual behaves and executes the required activities. Individuals from poor backgrounds are
likely to face challenges in physical and mental health (Balvin&Banati, 2017). Brain
development is affected by economic challenges that may cause stress. Young people may not
embrace the changes, thus affecting how their productivity.
Stressors during adolescents are likely to affect how an individual relates to the
environment. Balvin and Banati (2017) argued that the adolescent brain is prone to stress, and
chronic production of stress may affect memory, learning, mental health, and emotional
processing. Therefore, adolescents should be equipped with skills and knowledge to overcome
stress. Resilience programs may help unlearn negative behavior, minimize risks, and build life
skills (Balvin&Banati, 2017). Such programs are critical and may help enhance the development
of the brain. However, the adolescents must embrace self-approaches that may help overcome
the stressor. Personal responsibilities are recommended to ensure positive goals are achieved.
They may help enhance positive brain development towards enhancing positive aspects in life.
Additionally, the transitioning from childhood to adulthood may require approaches to
deal with challenges. Adolescence is the psychological transitioning from child to adult,
accompanied by structural remodeling and neuronal reconfiguring of the brain (Balvin&Banati,
2017). These changes may enhance adult-level reasoning that may affect the mental capabilities
of an individual. Sexual and cerebral changes may influence the emotions of wanting to fit into
society (Balvin&Banati, 2017). Societal and peer expectations are likely to affect how an
individual behaves and interact with each other. Adolescents may engage in social learning that
TRAUMA AND THE BRAIN 5
may help adjust to the environmental condition (Balvin&Banati, 2017). Some of these changes
may be influenced by brain development that is directly affected by the environment.
Childhood Trauma
Childhood trauma affects brain development and may lead to psychological dysfunction.
Long-term effects are likely to be experienced because of the adverse impacts on the brain. Early
childhood trauma can cause the brain's neurobiological functions that directly affect cognitive
and physical functioning (Dye, 2018). An individual may not behave as expected because of the
negative aspects of the trauma. Some of the long-term effects of trauma include substance abuse,
psychiatric problems, and incarceration (Dye, 2018). These effects are likely to be experienced in
later stages of life. However, guidance and follow-ups may help address some of these long-term
effects of childhood trauma.
Childhood trauma affects cognitive development, and a child may face challenges when
relating with each other in the environment. The complexity of a child's experiences in society
may lead to traumatic events. Exposure to trauma in childhood affects children's cognition, self-
identity, and language (McLean, 2016). These challenges are directly linked to the disruption of
the brain's development. Trauma and adversity lead to the hyper-arousal of the hypothalamic-
pituitary-adrenal axis (HPA axis), which directly changes brain development (McLean, 2016).
These effects may affect the stress hormone system that may cause adverse impacts.
Hippocampus is affected when the stress hormone system is disrupted (McLean, 2016).
Therefore, the development of the key brain structures is affected where negative aspects are
likely to be experienced. Memory loss may be experienced where an individual may experience
challenges in the learning experiences
TRAUMA AND THE BRAIN 6
Additionally, children exposed to trauma are likely to be associated with low IQ and
delays in cognitive and language development (McLean, 2016). Cognitive and language
development are directly involved in brain functions. Trauma may have adverse impacts on the
learning experiences because language development is a critical aspect of learning. Adults with a
history of trauma have small volume hippocampal and low memory functions (McLean, 2016).
The hHippocampusal is affected by past traumatic events that are likely to affect brain structures'
development. Therefore, childhood experiences may affect how an individual interacts and
behave when interacting with each other. Children experiencing abuse may have challenges in
the management of social and emotional information (McLean, 2016). Emotional processing of
social information is affected by traumatic environments. Therefore, adverse events are likely to
be experienced when regulating the emotions of an individual.
How Childhood Trauma Affects Health Across Lifetime
Childhood trauma affects the health of an individual because of the changes in behavior
and relationship with people. McLean (2016) argued that adverse childhood outcomes affect
physical and mental health. Adverse mental health outcomes are likely to be experienced because
of the challenges in brain development. Traumatic events are likely to affect how an individual
behaves because of the challenges in management. Stress hormones are likely to affect emotional
processing that affects mental health (Balvin & Banati, 2017).Emotional processing is a critical
aspect that is affected by the harsh environment. Adverse mental health outcomes are likely to be
experienced because of the challenges faced in the environment.
Additionally, adverse outcomes are likely to be experienced when children experience
traumatic events. Childhood trauma is the seventh out of 10ten leading causes of death in
America because of the impact on health (Harris, 2014). It may affect the immune system and
TRAUMA AND THE BRAIN 7
hormonal systems that are critical towards enhancing positive aspects of life. High exposure to
childhood trauma may lead to heart disease and lung cancer (Harris, 2014). These diseases may
affect life expectancy because of the challenges in the immune system. Some of these diseases
may be experienced in adulthood because of the changes in brain development. The exposure to
childhood trauma is hardly diagnosed and screened by doctors (Harris, 2014). The lack of
training may lead to diseases that are experienced when an individual grows up.
Child abuse may include abuse and neglect that affect the psychology of the people. High
adverse childhood experiences are lead to worse health outcomes (Harris, 2014). The
relationship between drug response and adverse childhood experiences is likely to affect how
people view childhood outcomes. Childhood trauma may lead to depression, hepatitis,
suicidality, and chronic obstructive pulmonary disease (Harris, 2014). These diseases cause
adverse outcomes because of the negative aspects of the diseases. Individuals who had a rough
childhood are likely to engage in smoking and drinking activities (Harris, 2014). These activities
are likely to ruin the health of an individual during adulthood. An individual will engage in such
activities to console themselves or revenge for such actions. These changes are likely to affect
the immune system, and an individual may experience infections.
Stress
Stress response mechanisms may be effective in coping with challenging situations.
However, long-lasting stress is likely to affect the brain processes, which may later affect the
behaviors. Stressors affect social behavior that directly impacts how people relate in society
(Sandi & Haller, 2015). Reduction of sociability may be experienced because an individual may
experience negative aspects. Early stressors may increase aggressiveness based on the
environment's interactions (Sandi & Haller, 2015). These challenges are likely to affect how
TRAUMA AND THE BRAIN 8
individuals perform in the workplace. Changes in social brain systems are likely to be affected
by stressors that influence the brain's normal processes (Sandi & Haller, 2015). Social cognition
of tasks is a critical aspect that may help enhance positive aspects of life.
Additionally,prenatal and early postnatal stress impinge brain development, while
childhood and adulthood stress affects social learning (Sandi & Haller, 2015). This argument is
based on how the individual develops and interacts in the environment. Individuals tend to learn
and discover new aspects during adolescence or early adulthood. Therefore, stressors are likely
to affect how an individual captures new concepts of life. Mediobasal hypothalamus and dorsal
aspects of the periaqueductal gray are affected by the social challenges that elicit aggressiveness
(Sandi & Haller, 2015). Some of these aspects may trigger negative social behaviors that affect
people's activity. Poverty, poor housing, family structure changes, social marginalization, and
isolation are causes of stress (Miller & Rasmussen, 2010). These challenges may affect brain
functions because an individual will always think about ways to avoid the challenges.
How Stress Affects the Brain
Stress is often characterized by feelings of isolation, irritability, and forgetting some
aspects. Chronic stress may affect the brain structure, function, and size, especially when an
individual cannot control it (Murgia). These effects may be experienced when an individual faces
conditions that make an individual unable to control them. Stressful conditions are likely to
trigger the HPA axis to produce cortisol, which may later cause havoc on the brain (Murgia).
These effects are likely to affect how an individual interacts and participates in the activities in
society. High levels of cortisol deteriorate the hippocampus's electronic signals, which are
associated with memory, learning, and stress control (Murgia). These challenges may be
experienced when an individual faces stressful conditions. High exposure to stress during
TRAUMA AND THE BRAIN 9
childhood may later lead to diseases in adulthood. This is because of the changes in the normal
development of the brain.
Disturbances of the brain structure and functions may affect the control of stress.
Increased cortisol levels may cause a shrink of the brain size and a loss of synaptic connections
between the neurons (Murgia). The brain is affected, and adverse impacts are likely to be
experienced because of the decrease in brain size. Shrinking of the prefrontal cortex affects
behaviors of decision-making, judgment, and concentration (Murgia). These perspectives are
likely to trigger the memory, making an individual have difficulties in memory. Chronic stress
affects the memory where negative aspects are likely to be experienced. Effects of stress may be
directed to the brain's DNA (Murgia). Therefore, offsprings are likely to experience stress effects
if the mothers had experienced high levels of stress.
Traumatic stressors are likely to have lifelong effects that involve the brain processes.
Bremner (1999) argued that patients with posttraumatic disorder (PSTD) had challenges in the
hippocampal. The neuropsychological functions are likely to be affected where negative results
are likely to be experienced. The dysfunctions of the hippocampus indicate that an individual
may have challenges in cognitive, neurohormonal, and neurochemical responses (Bremner,
1999). The challenges in dealing with stress may cause adverse impacts when an individual faces
challenges. Prenatal exposure to glucocorticoid may lead to hippocampal damage, which may
later affect the learning experiences (Bremner, 1999). Prenatal exposures are likely to affect
adulthood.
Effects of Childhood Trauma on the Brain
Childhood trauma affects the brain structures, leading to high levels of stress, which may
alter an individual's emotions. An increase in stress levels may affect the heart rates and
TRAUMA AND THE BRAIN 10
elevation of stress hormones (Purnomo, 2020). Some of these effects are likely to affect how an
individual interacts and relate with each other. An increase in heart rates may increase the risk of
heart diseases that are likely to be experienced in adulthood. Toxic stress may affect the anterior
cingulate cortex and prefrontal cortex (Purnomo, 2020). Childhood trauma is likely to influence
how an individual manages stress. The dysfunctions of the brain structures may lead to
complications in later stages of life. An individual may face difficulties when managing stressful
environments that affect people's performance.
Additionally, childhood trauma affects the behavioral responses of an individual to
external stimuli. Cortisol hormone increases blood pressure, respiration, heart rate respiration,
and muscle tension (Purnomo, 2020). The hormone may increase when the regulation
mechanism system is affected by traumatic stresses. These effects are likely to affect the
behavior of an individual towards the environment.
Solving Trauma
Interventions toward trauma should enhance long-term effects because traumatic events
have memories. Imipramine, amitriptyline, and phenelzine are effective drugs that can be used in
the treatment of PTSD (Bremner, 2006). The effects of the drugs may vary in different patients,
where positive aspects should be enhanced. Antidepressant promotes nerve development of the
hippocampus through enhancing the uptake of inhibitors (Bremner, 2006). These changes will
require a physician or nurse to enhance pharmacological treatment. However, the negative aspect
may be achieved when the patients are involved in the treatment plan. Individuals facing
traumatic events
Overcoming trauma may require aspects that can help enhance positive attitudes towards
an activity or environment. Purnomo (2020) suggested that an individual should build confidence
TRAUMA AND THE BRAIN 11
towards a common goal. Confidence may help address some of the negative aspects in life that
make an individual be stressed. Building trust and a sense of community may help a child
overcome toxic stress (Purnomo, 2020). The community may involve family members and
friends who may help enhance the child's self-esteem and confidence. Positive aspects can be
realized in society when a sense of community can be embraced in society. Overcoming trauma
may involve including aspects that affect the people. The negative aspects that lead to stress
should be avoided towards embracing positive aspects in life.
Additionally, a collaborative approach may be effective in overcoming trauma. The
approach may involve family members, friends, and individuals within the environment.
Eradicating the traumatic stressor is an effective aspect that may help enhance positive results
among the children.Drug therapy may also be effective in addressing the stress levels that affect
the brain structure. Bremner (1999) suggested that phenytoin, tianeptine, and
dihydroepiandrosterone can be used to reverse the stress that affects the hippocampus. Therefore,
positive outcomes can be realized through the incorporation of agents that will help control the
stress levels. The agents modulate excitatory amino acid-induced neurotoxicity, which directly
impacts the hippocampal (Bremner., 1999). The author further suggested reversibility is possible
even after neural death. However, healthcare professionals must be involved in enhancing
positive outcomes are achieved.
Conclusion
Traumatic events are likely to affect brain structures and functions. An individual may
experience challenges when addressing the stressors because of the adverse outcomes. Some of
the brain regions affected include the prefrontal cortex and hippocampus. The disruption of the
brain functions and system may cause diseases because some of the critical aspects are controlled
TRAUMA AND THE BRAIN 12
by the brain organs. Childhood trauma may cause suicidality, depression, lung cancer, and heart
diseases. The trauma may cause adverse impacts because an individual may have negative
memories of the events. Trauma may be treated through pharmacological treatment such as
antidepressants. Non-pharmacological treatment may include therapy and social support to
enhance positive aspects. The treatment may help in enhancing positive aspects and restructuring
of the damaged brain structures.
