Abstract
● What is Trauma?
According to the American Psychological Association (APA), trauma is “an
emotional response to a terrible event.
There can be different events and experiences which can be particularly
traumatic for individuals such as :
- Physical Abuse
- Sexual Abuse
- Psychological abuse and neglect
- Natural Disasters
- Terrorism and violence
- Bullying and cyberbullying
- Community or school violence
- War and displacement
- Illness or Serious accidents
There are several types of Trauma including :
- Acute Trauma - These result from a single stressful or dangerous event
- Chronic Trauma - These result from repeated and prolonged to highly stressful
events.
- Complex Trauma - These results from the exposure of multiple stressful events
● What is the Impact of Trauma ?
- Neurobiological changes : Adolescence is a period of significant brain
development. Trauma during this critical period can disrupt normal
neurodevelopmental processes.Exposure to childhood trauma can impact
brain development over time, leading to changes in the structure and
function of multiple stress-sensitive areas, including the hippocampus,
prefrontal cortex (PFC), and the amygdala.
➢ Hippocampus:
Role:
- Memory Formation: Essential for encoding and retrieving new memories.
- Emotional Regulation: Plays a role in regulating emotional responses and stress.
- Spatial Navigation : Involved in understanding spatial environments and learning.
Alterations:
Structural Changes:
- Reduced Volume: Chronic trauma can lead to a reduction in hippocampal
volume, which may impact memory and learning abilities.
- Cell Damage: Trauma can cause stress-induced damage to hippocampal
neurons, affecting overall brain health.
Functional Changes:
- Impaired Memory: Trauma can lead to difficulties in forming and retrieving
memories, including both episodic and spatial memories.
- Altered Emotional Processing: Trauma-induced changes in the hippocampus
can disrupt its interaction with the amygdala, leading to heightened emotional
reactivity and difficulty regulating stress.
➢ Prefrontal Cortex (PFC):
Role :
- Executive Functions: Manages planning, decision-making,
problem-solving, and goal-setting.
- Impulse Control: Regulates self-control and inhibition of inappropriate
behaviors.
- Emotional Regulation: Modulates emotional responses and integrates
emotional information with cognitive processes.
- Social Behavior: Facilitates understanding and navigating social norms
and interactions.
Alterations:
Structural Changes:
- Reduced Volume: Trauma can lead to reductions in the size of the
PFC, which may impair cognitive and executive functions.
- Altered Connectivity: Trauma can affect the connectivity between
the PFC and other brain regions, such as the amygdala, leading to
difficulties in integrating emotional and cognitive information.
Functional Changes:
- Impaired Executive Functions: Trauma can disrupt the PFC’s role
in managing complex cognitive tasks, including planning and
decision-making.
- Increased Impulsivity: Damage or dysfunction in the PFC can
result in reduced impulse control and increased risk-taking
behaviors.
- Difficulty in Emotional Regulation: Trauma can impair the PFC’s
ability to regulate emotional responses, leading to increased
emotional reactivity and difficulty managing stress.
➢ Amygdala :
Role :
- Emotional Processing: Crucial for detecting and responding to emotional
stimuli, especially fear and threats.
- Fear Conditioning: Involved in learning and remembering fear-related
experiences.
- Emotional Memory: Contributes to the encoding and retrieval of
emotionally charged memories.
- Stress Response: Plays a role in initiating and regulating the body's
stress response.
Alterations :
Structural Changes:
- Increased Volume: Chronic trauma can lead to an increase in amygdala volume,
which may be associated with heightened emotional reactivity and stress
responses.
- Altered Connectivity: Trauma can affect the connectivity between the amygdala
and other brain regions, such as the prefrontal cortex, potentially disrupting
emotional regulation and cognitive control.
Functional Changes:
- Heightened Reactivity: Trauma can lead to increased amygdala activity in
response to stress and emotional stimuli, resulting in heightened fear and
anxiety.
- Impaired Emotional Regulation: Increased amygdala reactivity can interfere
with the ability to regulate emotions effectively, leading to difficulties in managing
stress and emotional responses.
- Altered Fear Processing: Trauma can affect the amygdala’s role in fear
conditioning and memory, leading to exaggerated fear responses or difficulty
distinguishing between safe and threatening situations.
● What is the difference between impact of trauma on an adult from impact
on an adolescent ?
Brain Development:
- Adolescents: The adolescent brain is still developing, particularly in areas
related to executive function, emotional regulation, and social processing.
Trauma during this period can disrupt these developmental processes,
potentially leading to more pronounced or different effects compared to
adults. For instance, trauma can interfere with the maturation of the
prefrontal cortex, affecting decision-making and impulse control.
- Adults: By adulthood, the brain has typically reached full maturation,
though it remains plastic and capable of change. While trauma can still
impact brain function and structure, the effects may be less about
disrupting developmental processes and more about exacerbating or
triggering issues that were already present.
Emotional and Cognitive Processing
- Adolescents: Trauma during adolescence can profoundly affect
emotional and cognitive development. Adolescents are developing their
self-identity and coping mechanisms, so trauma can interfere with this
process, potentially leading to issues like emotional instability, identity
confusion, or difficulty forming healthy relationships.
- Adults: Adults generally have more established coping mechanisms and
life experiences.Adults may have more developed strategies for managing
and processing trauma compared to adolescents.
Psychological and Behavioral Responses :
- Adolescents: The psychological impact of trauma on adolescents can include
heightened vulnerability to mood disorders, behavioral issues, and risky
behaviors as they explore boundaries and test limits. Trauma can also lead to
disruptions in the development of social skills and self-regulation.
- Adults: Adults might experience trauma as exacerbations of existing mental
health issues, or as triggers for new conditions. Their responses might include
avoidance, substance use, or difficulty in maintaining relationships. Adult trauma
can also impact their ability to function effectively in their personal and
professional lives.
● What are some real life examples of adolescents getting affected by
trauma?
- Child Abuse:
Example: A teenager who has experienced physical or emotional abuse at home might
struggle with trust issues, emotional instability, and difficulties in forming healthy
relationships. They may also exhibit academic decline and behavioral problems, such
as aggression or withdrawal.
- Witnessing Violence:
Example: An adolescent who witnesses domestic violence or community violence may
develop symptoms of PTSD, including flashbacks, nightmares, and heightened anxiety.
This can lead to difficulties in school, such as concentration problems or avoidance
behaviors.
- Bullying:
Example: A teenager who is bullied at school may experience significant emotional
distress, leading to depression, anxiety, and low self-esteem. They may also show signs
of self-harm or suicidal ideation as a result of the ongoing emotional trauma.
- Loss of a Parent:
Example: Adolescents who lose a parent to death or separation might struggle with grief
and adjustment issues. This loss can affect their academic performance, social
interactions, and mental health, leading to depression or difficulties in maintaining
friendships.
- Natural Disasters:
Example: Teens who experience natural disasters such as hurricanes or earthquakes
might develop trauma-related symptoms like hypervigilance, nightmares, or difficulty
concentrating. Their sense of safety and security can be profoundly shaken, affecting
their daily functioning.
- Sexual Assault:
Example: A teenager who is a victim of sexual assault may experience severe
emotional and psychological distress, including PTSD, depression, and anxiety. They
might struggle with issues of self-worth and have difficulties in trusting others or
engaging in healthy relationships.
- Family Separation:
Example: Adolescents who are separated from their families due to immigration issues
or foster care placement can experience significant trauma. This separation can lead to
feelings of abandonment, instability, and difficulties in adjusting to new environments or
caregivers.
- Exposure to Substance Abuse :
Example: Teens who grow up in environments with high levels of substance abuse may
face emotional neglect or abuse, leading to developmental issues, substance use
problems, and difficulties in forming stable relationships.
● What are long term effects ?
The emotional effects of a trauma can last a long time. Sometimes people react in ways
that cause more stress or self-harm, like cutting, running away, or abusing drugs and
alcohol. It can be hard to move on.
For some people, trauma can lead to a mental health condition called post traumatic
stress disorder (PTSD). This is a type of stress that's so intense it overwhelms the
ability to cope.
● What do teens suffering from PTSD experience ?
teens with PTSD experience the following symptoms:
- Re-living: The child may experience flashbacks and severe emotional
reactions to the traumatic events. They may experience fear, guilt, or
sadness. Reactions are sometimes physical and manifest as shaking,
chills, or palpitations.
- Intense emotions: The child may feel disproportionately irritable and
angry or experience ongoing fear and sadness. In addition, the child may
be unable to feel or express positive emotions.
- Avoidance: The child may avoid people, places, and activities they once
enjoyed if it reminds them of the traumatic event.
-
● How to heal from trauma ?
- Acknowledge the event : not acknowledging the event and slipping into
denial will slow down the process of healing
- Accept support : except support from either your parents , pears ,
teachers etc.
- Find the right help : Find help which is the right fit for you , be it either a
therapist , school counselor , a support group or just someone to vent to.
- Practice self care (Do things you enjoy) : Put yourself first , enjoy self
care.Conduct simple practices like a long bath , exercising , eating a good
meal, watching your favorite series, reading a book , meditating etc.
- Connect with society : Join social groups or a community you associate
yourself with , make friends and connect with different people.
- Practice Mindfulness and Meditation : Start being mindful of your
emotions and the situation around you , which will make you come in tune
with your feelings and help you respond appropriately
- Avoid Addictions : Turning to addictions might give you temporary relief
but would cause long - term problems . Instead have healthy practices like
journaling , drawing , dancing basically anything that helps express or deal
with the feelings you are going through
