Post Traumatic Stress Disorder: Treatment and PreventionPost-Traumatic Stress Disorder (PTSD) is an emotional disorder characterized by exposure to life threatening traumatic events, the subsequent recollection of these events in the form of intrusive thoughts, images, nightmares and memories, the need to avoid any reminders of the trauma, and an overall experience of the world as an unsafe place. People who suffer from PTSD are often anxious and feel a need to withdraw from many-otherwise enjoyable- aspects of life.
