post-traumatic stress disorder (ptsd)
An anxiety disorder associated with serious traumatic events and characterized by such symptoms as guilt about surviving or reliving the trauma in dreams or numbness and lack of involvement with reality or recurrent thoughts and images.

Posttraumatic stress disorder is also characterized by aversive anxiety-related experiences, behaviors, and physiological responses that develop after exposure to a psychologically traumatic event (sometimes months after). Its features persist for longer than 30 days, which distinguishes it from the briefer acute stress disorder and are disruptive to all aspects of life. It has three sub-forms: acute, chronic, and delayed-onset.

Diagnostic symptoms for PTSD include re-experiencing the original trauma(s) through flashbacks or nightmares, avoidance of stimuli associated with the trauma, and increased arousal -- such as difficulty falling or staying asleep, anger, and hypervigilance. Formal diagnostic criteria (both DSM-IV-TR and ICD-10) require that the symptoms last more than one month and cause significant impairment in social, occupational, or other important areas of functioning.
