No such thing: There is no "dual personality disorder" in the mental health diagnostic system. However, there is a dissociative identity disorder -- where 2 or more alternate identity or personality states take control of a person. Each of these has its own characteristics, mannerisms, memories, and ways of experiencing -- and behaving in -- the world. It can follow from severe childhood trauma.
