Multiple Personality Disorder
Multiple Personality Disorder -- today, known as Dissociative Identity Disorder -- is a personality disorder where an individual seems to possess more than one personality. People who suffer from this disorder generally have gone through traumatic childhood experiences that have caused the formation of more than one personality in order to psychologically escape from their situation. A high percentage of people who suffer from this disorder have been sexually abused as a child. Also, many people mistakenly refer to people with MPD as schizophrenics, but they are completely different disorders.
