Multiple personality disorder

Re-classifications

In 1994, the fourth edition of the DSM replaced the criteria again and changed the name of the condition from "multiple personality disorder" to the current "dissociative identity disorder" to emphasize the importance of changes to consciousness and identity rather than personality. The inclusion of interpersonality amnesia helped to distinguish DID from dissociative disorder not otherwise specified (DDNOS), but the condition retains an inherent subjectivity due to difficulty in defining terms such as personality, identity, ego-state, and even amnesia. The ICD-10 classified DID as a "Dissociative [conversion] disorder" and used the name "multiple personality disorder" with the classification number of F44.81. In the ICD-11, the World Health Organization have classified DID under the name "dissociative identity disorder" (code 6B64), and most cases formerly diagnosed as DDNOS are classified as "partial dissociative identity disorder" (code 6B65).
