PTSD

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):
    1. Intrusion: Flashbacks, nightmares, or intrusive thoughts.
    2. Avoidance: Efforts to avoid trauma-related thoughts, feelings, or situations.
    3. Negative Changes: Distorted beliefs, emotional numbness, or detachment.
    4. 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)

  • Psychotherapy:
    • Cognitive-behavioral therapy (CBT): ~$100–$250/session.
    • Eye movement desensitization and reprocessing (EMDR): ~$150–$300/session.
  • Medications:
    • SSRIs (e.g., sertraline): ~$10–$50/month.
    • Prazosin for nightmares: ~$10–$30/month.

9. Advanced Treatment Options with Cost (USD)

  • Ketamine Therapy: ~$500–$1,000 per session for treatment-resistant PTSD.
  • Transcranial Magnetic Stimulation (TMS): ~$5,000–$15,000 for a full course (20–30 sessions).
  • MDMA-Assisted Psychotherapy (experimental): Costs vary, ~$10,000+ for trial-based treatments.

10. Pharmacological Treatment

  • First-line: SSRIs (e.g., sertraline, paroxetine) and SNRIs (e.g., venlafaxine).
  • Adjunctive Treatments: Prazosin for nightmares, antipsychotics for severe agitation.
  • Refractory Cases: Consider mirtazapine, trazodone, or experimental therapies like ketamine.
