Post Traumatic Stress Disorder

Post traumatic stress disorder (PTSD) is a type of anxiety disorder that occurs after an experience causing real or perceived serious harm. The condition is characterized by four kinds of symptoms: Intrusional memories. Patients re-live the event through flashbacks and nightmares. The memory may be triggered by a sound or sight, like a car backfiring (representing gun fire or an explosion) or news of a crash or assault. The memories may be quite vivid and elicit the same sights, sounds, smells and feelings as the original event. (More)
