While Ms. Steinberg's book will certainly bring a great deal of much-needed attention to a severely neglected area of psychology, much of what I had hoped to gain from the book at the outset was ignored in favor of an exhaustive and nearly exclusive look at Dissociative Identity Disorder (DID). It is my impression that DID, a topic whose sensational aura has proven irresistible to both the media and researchers, has been examined far more than the rest of the spectrum of dissociative disorders. What is frustrating about this book is how Ms. Steinberg begins by telling us how dissociation, in ALL of its manifestations, is widely ignored and far more common than the public realizes. She goes on to discuss Derealization, Depersonalization and Amnesia alone for a chapter or two. The rest of the book looks at them ONLY in the context of DID. It's as if she too has fallen for the romance and mystery that surrounds DID at the expense of much-needed focus to the other disorders. While their illnesses lie on the continuum of dissociation that is nicely detailed by the author, sufferers of Depersonalization (DP) and Derealization (DR) are probably among the most misdiagnosed, mistreated and misunderstood patients in the American Health Care system. DP and DR are extremely devastating to the patient's psyche, and can ruin one's life, but because they seem outwardly functional patients are often treated as low priorities. It never ceases to amaze me when a psychologist, psychiatrist or physician has never even heard of these disorders and doesn't know the first thing about treating them. If it is her opinion that treatment for these disorders is identical to treatment for DID, she must make this clear.
