Dissociative identity disorder is conceptualized as a childhood onset, posttraumatic developmental disorder in which the child is unable to consolidate a unified sense of self. Detachment from emotional and physical pain during trauma can result in alterations in memory encoding and storage. In turn, this leads to fragmentation and compartmentalization of memory and impairments in retrieving memory.2,4,19 Exposure to early, usually repeated trauma results in the creation of discrete behavioral states that can persist and, over later development, become elaborated, ultimately developing into the alternate identities of dissociative identity disorder.
