DID Fact Sheet
What Is Dissociative Identity Disorder (DID)?
Dissociative identity disorder (DID), previously referred to as multiple personality disorder, is a dissociative disorder involving a disturbance of identity in which two or more separate and distinct personality states (or identities) control an individual’s behavior at different times. When under the control of one identity, a person is usually unable to remember some of the events that occurred while other personalities were in control. The different identities, referred to as alters, may exhibit differences in speech, mannerisms, attitudes, thoughts and gender orientation. The alters may even present physical differences, such as allergies, right-or-left handedness or the need for eyeglass prescriptions. These differences between alters are often quite striking.
A person living with DID may have as few as two alters or as many as 100. The average number is about 10. Often alters are stable over time, continuing to play specific roles in the person’s life for years. Some alters may harbor aggressive tendencies, directed toward individuals in the person’s environment or toward other alters within the person.
At the time a person living with DID first seeks professional help, he or she is usually not aware of their condition. A very common complaint in people affected by DID is episodes of amnesia, or time loss. These individuals may be unable to remember events in all or part of a proceeding time period. They may repeatedly encounter unfamiliar people who claim to know them, find themselves somewhere without knowing how they got there or find items that they don’t remember purchasing among their possessions.
What Are The Symptoms Of DID?
Often people living with DID are depressed or even suicidal and self-mutilation is common in this group. Approximately one-third of individuals affected complain of auditory or visual hallucinations.
While the causes are unknown, statistics show that DID occurs in 0.01 to 1 percent of the general population. DID is a serious mental illness that occurs across all ethnic groups and all income levels. It affects women nine times more than men.
In addition to experiencing separate identities, individuals living with DID may also experience many other symptoms. Some of these symptoms include:
- Depression.
- Suicidal tendencies.
- Anxiety, panic attacks.
- Alcohol and drug abuse.
- Confusion.
- Memory problems.
- Delusions.
- Headaches.
- Flashbacks.
- Eating disorders.
- Personality change.
- Selective loss of memory.
- Disorientation.
