Post Traumatic Stress Disorder - PTSD

Post traumatic stress disorder (PTSD) is an anxiety disorder that can develop after exposure to a terrifying event or ordeal in which grave physical harm occurred or was threatened. Traumatic events that can trigger PTSD include violent personal assaults such as rape or mugging, natural or human-caused disasters, accidents, or military combat. PTSD can be extremely disabling.
Military troops who served in the Vietnam and Gulf Wars; rescue workers involved in the aftermath of disasters like the terrorist attacks on New York City and Washington, D.C.; survivors of the Oklahoma City bombing; survivors of accidents, rape, physical and sexual abuse, and other crimes; immigrants fleeing violence in their countries; survivors of the 1994 California earthquake, the 1997 North and South Dakota floods, and hurricanes Hugo and Andrew; and people who witness traumatic events are among those at risk for developing PTSD. Families of victims can also develop the disorder. 
Fortunately, through research supported by the National Institute of Mental Health (NIMH) and the Department of Veterans Affairs (VA), effective treatments have been developed to help people with PTSD. Research is also helping scientists better understand the condition and how it affects the brain and the rest of the body.
