Evolution and posttraumatic stress

"This book is the first to examine PTSD from an evolutionary perspective. Beginning with a review of conventional theories, Chris Cantor provides a clear and succinct overview of the history, clinical features and epidemiology of PTSD before going on to introduce and integrate evolutionary theory." "This original presentation of PTSD as a defensive strategy describes how the use of evolutionary theory provides a more coherent and successful model for diagnosis and treatment, greatly improving understanding of usually mystifying symptoms. It will be of great interest to psychiatrists, psychologists, psychotherapists, sociologists and anthropologists."--BOOK JACKET.
