Post-Traumatic Stress Disorder (PTSD)

Post-Traumatic Stress Disorder (PTSD) is a mental health condition triggered by experiencing or witnessing a traumatic event. Such events might include natural disasters, serious accidents, terrorist acts, war/combat, rape or other violent personal assaults. While many people experience short-term distress after a traumatic event, PTSD occurs when the symptoms last for more than a month and are severe enough to interfere with daily life.

What are the Symptoms of Post-Traumatic Stress Disorder?

PTSD symptoms are generally grouped into four types:

Intrusive Memories

Unwanted distressing memories of the traumatic event, flashbacks, reliving the event as if it were happening again and severe emotional distress or physical reactions to reminders of the trauma.


Avoiding thinking or talking about the traumatic event, avoiding places, activities or people that remind you of the trauma.

Negative Changes in Thinking and Mood

Negative thoughts about yourself, other people, or the world, hopelessness about the future, memory problems, including not remembering important aspects of the traumatic event, difficulty maintaining close relationships, feeling detached from family and friends, lack of interest in activities once enjoyed and difficulty experiencing positive emotions.

Changes in Physical and Emotional Reactions

Being easily startled or frightened, always being on guard for danger, self-destructive behavior such as drinking too much or driving too fast, trouble sleeping, trouble concentrating, irritability, angry outbursts, or aggressive behavior and overwhelming guilt or shame.

How to Know if You Have Post-Traumatic Stress Disorder

Determining if you have PTSD involves looking for the above symptoms, especially if they persist for more than a month after the traumatic event. A formal diagnosis must be made by a mental health professional, who will use tools such as the PTSD Checklist (PCL-5) or conduct structured clinical interviews.

Can Post-Traumatic Stress Disorder Cause Memory Loss?

Yes, PTSD can cause memory problems, including difficulty remembering parts of the traumatic event, and in some cases more generalized memory issues. Stress hormones released during trauma can affect brain regions like the hippocampus, which is crucial for memory formation.

How Does Post-Traumatic Stress Disorder Affect the Brain?

PTSD can lead to structural and functional changes in the brain, particularly in areas like the amygdala (involved in fear responses), prefrontal cortex (responsible for executive functions and regulating emotions), and hippocampus (important for memory and learning). These changes can result in heightened fear responses, difficulty regulating emotions, and memory problems.

What Factors Play a Role in Post-Traumatic Stress Disorder?

Several factors can influence the development and severity of PTSD:

  • Severity and Proximity of Trauma: More severe and closer exposure to the traumatic event increases the risk.
  • History of Previous Trauma: Individuals with past trauma experiences may be more susceptible.
  • Mental Health History: Pre-existing mental health conditions can exacerbate PTSD symptoms.
  • Support Systems: Lack of social support can hinder recovery, while strong support systems can be protective.
  • Biological Factors: Genetic predispositions and differences in brain structure and function can also play a role.

How to Treat Post-Traumatic Stress Disorder

PTSD can be treated through various therapies and medications:


Cognitive Behavioral Therapy (CBT), particularly Trauma-Focused CBT, Eye Movement Desensitization and Reprocessing (EMDR), and Exposure Therapy.


Antidepressants such as SSRIs (e.g., sertraline, paroxetine) and SNRIs (e.g., venlafaxine) are commonly prescribed. Other medications might include Prazosin for reducing nightmares.

Self-Care and Support

Regular physical activity, maintaining a healthy diet, adequate sleep, and joining support groups can also help.

The Bottom Line

Understanding PTSD and its impact is crucial for those affected and their loved ones. Early intervention and appropriate treatment can significantly improve the quality of life for individuals with PTSD.
