Posttraumatic Stress Disorder

The first formal psychiatric diagnosis in modern medicine defined to occur as a result of exposure to a traumatic event or experience. Current formulation consists of four symptom clusters: re-experiencing (e.g. nightmares, intrusive memories); avoidance of trauma-related thoughts, feelings and reminders; negative cognitions and mood; and arousal and reactivity.
