1. Introduction
- Definition: Post-traumatic stress disorder (PTSD) is a mental health condition triggered by exposure to a traumatic event, leading to persistent emotional distress, intrusive thoughts, and behavioral changes.
- Epidemiology: PTSD affects approximately 3.5% of the global population annually, with higher prevalence in women and individuals exposed to combat, violence, or disasters.
- Significance: PTSD significantly impairs quality of life, relationships, and productivity and increases the risk of comorbidities such as depression and substance use disorders.
2. Causes and Risk Factors
- Causes:
- Experiencing or witnessing traumatic events (e.g., accidents, assaults, war).
- Prolonged exposure to trauma (e.g., domestic violence, abuse).
- Risk Factors:
- Pre-existing mental health conditions.
- Lack of social support.
- Genetic predisposition.
- Childhood trauma or adversity.
3. Pathophysiology
- Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, increased amygdala activity, and decreased prefrontal cortex regulation lead to heightened fear response, memory intrusion, and emotional dysregulation.
4. Symptoms and Features
- Core Symptoms (DSM-5 Criteria):
- Intrusion: Flashbacks, nightmares, or intrusive thoughts.
- Avoidance: Efforts to avoid trauma-related thoughts, feelings, or situations.
- Negative Changes: Distorted beliefs, emotional numbness, or detachment.
- Hyperarousal: Irritability, hypervigilance, insomnia, or exaggerated startle response.
- Duration: Symptoms lasting for more than one month after the trauma.
5. Complications
- Chronic anxiety and depression.
- Substance use disorders.
- Suicidal ideation or self-harm.
- Difficulty maintaining relationships or employment.
6. Diagnosis
- Clinical Assessment: Detailed history of trauma and symptom evaluation.
- Screening Tools:
- PTSD Checklist (PCL-5).
- Clinician-Administered PTSD Scale (CAPS-5).
7. Management Overview
- Goals: Reduce symptom severity, improve functioning, and prevent relapse.
- Approach: Psychotherapy as the cornerstone of treatment, often combined with pharmacotherapy.
8. Treatment Options with Cost (USD)

- Cognitive-behavioral therapy (CBT): ~$100–$250/session.
