Trauma memory, hyperarousal and avoidance — how threat learning overgeneralises and how evidence-based care supports recovery.
Key takeaways
PTSD can follow exposure to actual or threatened death, serious injury or sexual violence. Core features include intrusions, avoidance, negative alterations in cognition/mood and hyperarousal lasting beyond a month and impairing life. Not everyone exposed to trauma develops PTSD. Biology, prior adversity, social support and care access shape risk. Trauma-focused therapies have strong evidence; this page is educational, not treatment. Educational neuroscience context only — not medical advice, diagnosis or a substitute for emergency or clinical care. If you are in crisis, seek local emergency services or a licensed clinician.
