The essential feature of the Dissociative Disorders is a disruption in the usually integrated functions of consciousness, memory, identity, or perception of the environment. The disturbance may be sudden or gradual, transient or chronic. The following disorders are including in this section:
Dissociative Amnesia is characterized by an inability to recall important personal information, usually of a traumatic or stressful nature, that is too extensive to be explained by ordinary forgetfulness.
Dissociative Fugue is characterized by sudden, unexpected travel away from home or one's customary place of work, accompanied by an inability to recall one's past and confusion about personal identity or the assumption of a new identity.
Dissociative Identity Disorder (formerly Multiple Personality Disorder) is characterized by the presence of two or more distinct identities or personality states that recurrently take control of the individual's behavior accompanied by an inability to recall important personal information that is too extensive to be explained by ordinary forgetfulness.
Depersonalization Disorder is characterized by a persistent or recurrent feeling of being detached from one's mental processes or body that is accompanied by intact reality testing.
Dissociative Disorder Not Otherwise Specified is included for coding disorders in which the predominant feature is a dissociative symptom, but that do not meet the criteria for any specific Dissociative Disorder. (p. 477)
