Post-Traumatic Stress Disorder (PTSD) is an anxiety disorder that may develop after exposure to a terrifying event or ordeal in which severe physical harm occurred or was threatened.

Traumatic events that may trigger PTSD include violent personal assaults, natural or unnatural disasters, accidents, or military combat.

Many people with PTSD tend to re-experience the ordeal that set the disease in motion, especially when they are exposed to events or objects reminiscent of the trauma.

People who have suffered childhood abuse or other previous traumatic experiences are more likely to develop the disorder. And people who experience emotional distancing may be more prone to PTSD.
