PTSD

Robjant, K. & Fazel, M. (2010).  The emerging evidence for Narrative Exposure Therapy:  A review.  Clinical Psychology Review, 30, 1030-1039.

"The three core symptoms of PTSD are:

• Firstly the re-experiencing of intrusive vivid memories of traumatic events both during sleep and in the day, when the individual often has a sense they are re-living the event.
• Secondly, the active avoidance of anything that may trigger these memories, with associated emotional numbing, derealisation and depersonalisation.
• The final symptom is persistent hyperarousal and an exaggerated startle response, reflecting the readiness of the body's fight or flight response."
