Post-traumatic stress disorder in Vietnam veterans is shaped by combat exposure and by risk factors that extend beyond the battlefield, including pre-military adversity and family psychiatric history. NVVRS data estimate lifetime PTSD prevalence at 27.9% among Vietnam theater veterans and show notable differences by sex, along with current PTSD prevalence in men. This page also covers linked conditions, symptom patterns such as nightmares, avoidance, and hyperarousal, and reviews evidence-based treatments and remission rates.
