Overview: Understanding PTSD
Post-traumatic stress disorder develops after exposure to actual or threatened death, serious injury, or sexual violence. PTSD involves intrusive memories, avoidance, negative mood changes, and hyperarousal. Trauma affects the brain, body, and emotional regulation. Recovery is possible with appropriate treatment .
PTSD is not a sign of weakness; it's a normal response to abnormal events that continues longer than expected.
PTSD symptoms cluster into four categories: intrusive symptoms (flashbacks, nightmares), avoidance (avoiding reminders), negative cognitions and mood (guilt, emotional numbness), and arousal (hypervigilance, startled easily). Symptoms must persist for over one month and cause functional impairment.
Trauma Responses
Flashbacks make past trauma feel present. Nightmares disturb sleep. Avoidance of trauma reminders limits activities and relationships. Hypervigilance keeps the nervous system in constant threat detection. Depression, anger, and emotional numbness occur frequently. Some experience dissociation or depersonalization.
