PTSD II

This echoes my past post on PTSD. I'm no expert, but this guy is. From the NYTimes:

 

What others view as a mental disorder — post-traumatic stress disorder, that is — Dr. Shay prefers to see as a psychological injury of war. Initially, when a service member returns from war, he or she often retain the behaviors that they adopted for their own survival while in a combat zone, he says.

"Most of it really boils down to the valid adaptations in the mind and body to the real situation of other people trying to kill you,'' he said.
