Putnam demystifies multiple personality disorder (now known as dissociative identity disorder or DID) and places it in the context of current knowledge about the effects of childhood trauma. The book promises a synthesis of ideas, techniques, and treatment philosophies regarding MPD (DID) and not only fulfills this promise but also offers much more: it presents the disorder in its historical context, significantly contributing to the expansion of our understanding of the nature of human consciousness. Additionally, it can help us today to learn more about the psychobiological connections between mind and body. The clear and highly detailed presentation of all conceivable aspects of complex therapy aids all clinicians treating patients with MPD/DID and other dissociative disorders in achieving a balanced perspective.
