“The DSM concept of pathological dissociation has evolved from the early inclusive concept of a dissociative reaction in DSM-I to five distinct dissociative disorders in DSM-IV: dissociative amnesia, dissociative fugue, depersonalization disorder, DDNOS, and MPD/DID [Dissociative Identity Disorder]. The first four disorders are rarely challenged, but the existence of MPD/DID has been more or less continually under attack for more than a century. I perceive many of these attacks as misdirected at a mass media stereotype that does not resemble the actual clinical condition.”
