5. Is Multiple Personality Disorder Hereditary?
While schizophrenia, depression, anxiety, and many other mental health disorders are often genetic to some extent, multiple personality disorder is not thought to have a hereditary component. However, there is not much known about why some people develop DID after traumatic situations and others don’t.
Trauma remains the main known cause of multiple personality disorder. While it is possible for dissociative disorders to develop in adulthood, it is most common for DID to have an early onset in childhood as children struggle to process abuse and similar traumas and use imagination as a coping tool.
