Notable Cases of Dissociative Identity Disorder
Grasping the Basics of Dissociative Identity Disorder
Notable Cases of Dissociative Identity Disorder Dissociative Identity Disorder (DID), formerly called multiple personality disorder, is a complex mental health condition involving two or more distinct identities within one person. Each identity may have its own memories, behaviors, and traits. DID commonly develops from severe, long-term childhood trauma.
People with DID often have memory gaps, struggling to recall key personal events or information. They may also show dissociative symptoms like feeling disconnected from their body or emotions, experiencing depersonalization or derealization, and losing awareness of time.
Recent studies indicate that dissociative identity disorder (DID) may be more prevalent than once believed, affecting approximately 1% to 3% of people. Although DID has existed historically, it only gained widespread recognition and understanding in the late 20th century.
