Post-traumatic stress disorder: the history of a recent concept.

This review describes the history of PTSD in relation to military psychiatry, physiology, and crisis theory. It appears that the consequences of psychic trauma are often underestimated and mental health services often fail to provide adequate care. PTSD may be explained as an initially adequate reaction to danger, which becomes pathological if it does not disappear after the danger is gone. The authors argue in favour of better psychiatric intervention after traumatic events and better care for trauma victims.
