Multiple Personality Disorder (MPD) is an outdated term for Dissociative Identity Disorder (DID), which is a rare and controversial mental health condition characterized by disassociation, or a disruption in the integrated consciousness of self, identity, memory, and perception. People with DID have two or more separate personalities, and these identities control a person’s behavior at different times. The condition can cause memory loss, delusions, or depression, and it is usually caused by past trauma. Therapy can help people manage their behaviors and reduce the frequency of identity “switches,” and it’s important for anyone with DID to have a strong support system. Its worth noting that the media often portrays people with dissociative disorders, particularly DID, as being dangerous or violent, which is a harmful and inaccurate stereotype.
