How common is post-traumatic stress disorder (PTSD)?

As many as 7% to 12% of people will have post-traumatic stress disorder (PTSD) at some point in their lives. Among people who experience traumatic events, its incidence varies according to the event. The highest rates are found among survivors of rape, military combat or captivity, and ethnically or politically motivated imprisonment or genocide.

More than one million Vietnam veterans -- roughly 20% to 30% -- were diagnosed with PTSD, a percentage similar to that found among survivors of Hurricane Katrina in New Orleans. And 300,000 Iraq and Afghanistan vets -- that's almost 20% -- experienced symptoms of PTSD or major depression, according to a Research and Development (RAND) Corporation study.

This disorder is not only prominent among soldiers, but also firefighters, police officers, and victims of sexual assault. Between 8% and 10% of Americans will experience post-traumatic stress during their lifetimes; women are twice as likely to experience PTSD than men.
