Posttraumatic stress disorder (PTSD), once called shell shock or battle fatigue syndrome, is a serious condition that can develop after a person has experienced or witnessed a traumatic or terrifying event in which serious physical harm occurred or was threatened. PTSD is a lasting consequence of traumatic ordeals that cause intense fear, helplessness, or horror, such as a sexual or physical assault, the unexpected death of a loved one, an accident, war, or natural disaster. Families of victims can also develop PTSD, as can emergency personnel and rescue workers.

Most people who experience a traumatic event will have reactions that may include shock, anger, nervousness, fear, and even guilt. These reactions are common, and for most people, they go away over time. For a person with PTSD, however, these feelings continue and even increase, becoming so strong that they keep the person from living a normal life. People with PTSD have symptoms for longer than one month and cannot function as well as before the event occurred.
What Are the Symptoms of PTSD?

Symptoms of PTSD most often begin within three months of the event. In some cases, however, they do not begin until years later. The severity and duration of the illness vary. Some people recover within six months, while others suffer much longer.
