Dissociative Identity Disorder (DID) or multiple personality disorder is assumed to have its onset in childhood, but it is usually diagnosed in the fourth decade. It affects preponderantly women and typically runs a chronic, waxing and waning course. Comorbidities with other conditions (such as mood disorders and substance abuse) and its plethora of clinical manifestations may hinder timely diagnosing. Apart from marked impairments in the sense of identity and self (in the form of the existence of two or more distinct identities or personality states), inability to recall personal information (amnesia) is a common occurrence in DID. Currently.
