Multiple Personality Disorder: Legal Definition and Implications

Definition & Meaning

Multiple personality disorder, now officially known as dissociative identity disorder (DID), is a mental health condition characterized by the presence of two or more distinct identities or personality states within a single individual. These identities can take control of the person's behavior and consciousness at different times, leading to gaps in memory and a disconnection from one's sense of self.
