ICD-9 | 300.14 |
Dissociative identity disorder (DID), is a mental disorder. Its old name was multiple personality disorder.[1] It is listed in the mental health diagnosis manual DSM IV.[2]
The main symptom of DID is a person showing two or more "identities" or "personality states". The person behaves differently depending on which identity is in control. The second important symptom is when a person forgets important, personal things which people normally do not forget.
A person is not diagnosed with DID if the symptoms are caused by drugs, illness, or (with children) pretending to play with imaginary friends.[2] Doctors or psychologists must also rule out pretending to have DID for some personal gain or attention (malingering).[2][3] Most patients with DID are also diagnosed with other mental disorders.
