Dissociative Identity Disorder (DID)

Dissociative identity disorder (DID), formerly referred to as multiple personality disorder, is the existence in an individual of two or more distinct identities or personalities, each with its own pattern of perceiving and interacting with the environment. At least two of these personalities are considered to routinely take control of the individual's behavior, and there is also some associated memory loss, which is beyond normal forgetfulness. This memory loss is often referred to as "losing time". These symptoms must occur independently of substance abuse or a general medical condition.

Recent studies of mental health professionals demonstrate widespread skepticism of the validity of this diagnosis. In addition, the underlying theory of dissociative amnesia is the most contentious, disputed and debunked mental health notion of the past 50 years.

While dissociation is a demonstrable psychiatric condition that is tied to several different disorders, specifically those involving early childhood trauma and anxiety, multiple personality remains controversial. Despite the controversy, some mental health institutes, such as McLean Hospital, have wards specifically designated for dissociative identity disorder.
