Post-Traumatic Stress Disorder (PTSD)

Last reviewed Tuesday, December 31, 2024

PTSD is a trauma- and stressor-related disorder that can develop after experiencing or witnessing life-threatening events (e.g., combat, natural disaster, sexual assault). It involves intrusive memories, avoidance, negative alterations in mood/thinking, and heightened arousal.

Key Points:

  • Core Symptoms:
    1. Re-experiencing: Flashbacks, nightmares, intrusive thoughts.
    2. Avoidance: Steering clear of reminders of the trauma (places, people, thoughts).
    3. Negative Mood/Cognitions: Persistent fear, guilt, shame, distorted blame, loss of interest.
    4. Hyperarousal: Being “on edge,” startled easily, irritability, sleep difficulties.
  • Complex PTSD (C-PTSD): Often arises from prolonged or repeated trauma, featuring additional symptoms like emotion dysregulation and negative self-concept.
  • Treatment: Trauma-focused therapies (e.g., EMDR, trauma-focused CBT), medication (SSRIs, SNRIs), and supportive interventions (group therapy, service dogs).
