Dissociative identity disorder (DID), previously known as multiple personality disorder (MPD),[1] is a mental disorder on the dissociative spectrum characterized by at least two distinct and relatively enduring identities or dissociated personality states that alternately control a person's behavior, and is accompanied by memory impairment for important information not explained by ordinary forgetfulness. These symptoms are not accounted for by substance abuse, seizures, other medical conditions, nor by imaginative play in children.[2] Diagnosis is often difficult as there is considerable comorbidity with other mental disorders. Malingering should be considered if there is possible financial or forensic gain, as well as factitious disorder if help-seeking behavior is prominent.[2][3][4][5]

DID is one of the most controversial psychiatric disorders with no clear consensus regarding its diagnosis or treatment.[3] Research on effectiveness of treatment has been concerned primarily with clinical approaches and case studies. Dissociative symptoms range from common lapses in attention, becoming distracted by something else, and daydreaming, to pathological dissociative disorders.[6] No systematic, empirically-supported definition of "dissociation" exists.[7][8]

Although neither epidemiological surveys nor longitudinal studies have been done, it is thought DID rarely resolves spontaneously. Symptoms are said to vary over time.[6] In general, the prognosis is poor, especially for those with co-morbid disorders. There are few systematic data on the prevalence of DID.[4] The International Society for the Study of Trauma and Dissociation states that the prevalence is between 1 and 3% in the general population, and between 1 and 5% in inpatient groups in Europe and North America.[5] DID is diagnosed more frequently in North America than in the rest of the world, and is diagnosed three to nine times more often in females than in males.[4][7][9] The prevalence of DID increased greatly in the latter half of the 20th century, along with the number of identities (often referred to as "alters&quot claimed by patients (increasing from an average of two or three to approximately 16).[7] DID is also controversial within the legal system[3] where it has been used as a rarely successful form of the insanity defense.[10][11] The 1990s showed a parallel increase in the number of court cases involving the diagnosis.[12]

not to be confused with schizophrenia

1. Not to make light of it, but this seems to be an affliction that conveniently affects many

politicians. Vote for one person, then they turn into someone quite different when they get to Stepford, er, Washington, or just into office.

2. As I read the definition in the first paragraph the words "distinct personalities" struck me as a

pretty good definition of my brother who has been diagnosed with bi-polar. His mood swings last quite long and so he is either the biker or the preacher. Two distinct personalities. Any relationship?

Co-morbid disorders[edit]

Most dissociative disorder cases have co-morbid mental disorders, with an average of 8 axis I and 4.5 axis II DSM diagnoses.[7] The psychiatric history frequently contains multiple previous diagnoses of various disorders and treatment failures.[24] The most common presenting complaint of DID is depression, with headaches being a common neurological symptom. Co-morbid disorders can include substance abuse, eating disorders, anxiety, posttraumatic stress disorder (PTSD) and personality disorders.[25] A majority of those diagnosed with DID meet the criteria for DSM axis II personality disorders such as borderline personality disorder;[19] a significant minority meet the criteria for avoidant personality disorder and other personality disorders.[26] Further, data supports a high level of psychotic symptoms in DID, and that both individuals diagnosed with schizophrenia and DID have histories of trauma.[27] Individuals diagnosed with DID also demonstrate the highest hypnotizability of any clinical population.[22] The large number of symptoms presented by individuals diagnosed with DID has led to some clinicians to suggest that, rather than being a separate disorder, diagnosis of DID is actually an indication of the severity of the other disorders diagnosed in the patient.[7]
