What are the different types of post-traumatic stress disorder symptoms?

Post-traumatic stress disorder (PTSD) symptoms occur after a person experiences or witnesses a traumatic or extreme stressor, such as a life-threatening event, a natural disaster, or an assault. Symptoms fall into three categories: reliving the event, avoidance, and hyperarousal.

A person may relive the event through flashbacks, dreams, or intrusive thoughts. Avoidance often comes in the form of withdrawing from people or certain situations, or having difficulty remembering important aspects of the trauma. Common symptoms of hyperarousal include having trouble sleeping, being unusually vigilant, and startling easily. The symptoms must last more than a month to be considered signs of PTSD.
