Dissociative Identity Disorder

Overview

Description

Dissociative Identity Disorder (DID) is characterized by the presence of two or more distinct personality states or identities, which may be experienced as distinct selves or as an alteration in sense of self. These states are accompanied by recurrent gaps in recall of everyday events, personal information, and/or traumatic events, inconsistent with ordinary forgetting. The condition is closely linked to severe, chronic trauma, often beginning in early childhood.

Prevalence

Estimated prevalence in the general population is about 1–1.5%, higher in clinical populations, especially those with histories of severe trauma.

Age of Onset

Symptoms typically begin in early childhood, but diagnosis often occurs in adulthood.
