People with this disorder must endure psychological disturbance that is attributed to the experience of a major traumatic event. First recognized as a disorder in the 1970s in the aftermath of the Vietnam war. Often seen after harrowing war experiences, after a rape or assault, a severe automobile accident, a natural disaster, or the witnessing of someone's death. Symptoms include re-experiencing the event in the form of nightmares and flashbacks, emotional numbing, alienation, problems in social relations, an increased sense of vulnerability, and elevated arousal, anxiety, anger and guilt.
