Dissociative identity disorder (DID, also known as multiple personality disorder) is a psychiatric diagnosis. According to the DSM its essential feature "…is the presence of two or more distinct identities or personality states…that recurrently take control of behavior."
The diagnosis requires that at least two personalities (one may be the host) routinely take control of the individual’s behavior with an associated memory loss that goes beyond normal forgetfulness.Memory loss will occur in those with DID when an alternate part of the personality becomes dominant. DID is less common than other dissociative disorders, occurring in approximately 10% of dissociative disorder cases and .5-1% of the general population.Women tend to outnumber men in this disorder, resulting in about a 9:1 ratio.
