Dissociative Identity Disorder (formerly known as Multiple Personality Disorder) is a mental health state in which people have two or more distinct identities. These identities essentially have its own life as well as characteristics. According to Cleveland Clinic, DID is very rare and affects between 0.01 and 1% of the population. Furthermore, it affects anyone regardless of age and occurs in women more than men.
Symptoms of DID include amnesia, identity confusion, depersonalization or a sense of detachment from your body. DID might also occur with other psychiatric illnesses such as depression and sleep disorders. The dissociative attribute of DID is said to act as a way to manage with a person’s traumatic, violent, or painful situations that their conscious self cannot deal with.
