PTSD can result from any traumatic event—experiencing a natural disaster; being in a car accident; being a victim of violence, abuse, bullying, or sexual assault; seeing someone hurt or killed; or losing a friend or family member to violence. People who witness or experience such an event initially have trouble coping with their feelings but usually get better over time. If their symptoms worsen, last for a long time, or interfere with their daily lives, they likely have PTSD.

Though once considered primarily a disorder affecting military or combat veterans, PTSD can affect anyone of any age who has had a traumatic experience.
