Posttraumatic stress disorder affects Veterans across different eras and conflicts, with rates shaped by combat exposure, repeat deployments, and related conditions such as traumatic brain injury. The burden is not evenly distributed: female Veterans face higher risk, and many people report symptoms such as nightmares, flashbacks, avoidance, and hyperarousal that can persist when not treated. On this page, you’ll explore how PTSD prevalence varies by where and when Veterans served, which factors raise the odds, and how PTSD influences outcomes including suicide risk, homelessness, and employment. You’ll also review the evidence on therapies and medications that reduce symptoms and support recovery.
