What's the Recommended Treatment Plan for Dissociative Identity Disorder?
While there's no "cure" for dissociative identity disorder, long-term treatment is very successful, if the patient stays committed. Effective treatment includes talk therapy or psychotherapy, medications, hypnotherapy, and adjunctive therapies such as art or movement therapy.
Because oftentimes the symptoms of dissociative disorders occur with other disorders, such as anxiety and depression, dissociative disorder may be treated using the same drugs prescribed for those disorders. A person in treatment for a dissociative disorder might benefit from antidepressants or anti-anxiety medication.

What is dissociative identity disorder?
Dissociative identity disorder (DID) is a mental illness that involves the sufferer experiencing at least two clear identities or personality states, also called alters, each of which has a fairly consistent way of viewing and relating to the world. Some individuals with DID have been found to have personality states that have distinctly different ways of reacting, in terms of emotions, pulse, blood pressure, and even blood flow to the brain. This disorder was formerly called multiple personality disorder (MPD) and is often colloquially referred to as split personality disorder.
Statistics regarding this disorder indicate that the incidence of DID is about 1% of all adults (general population) in the United States, from 1%-20% of patients in psychiatric hospitals and is described as occurring in girls equally to boys and up to nine times more often in women compared to men. However, this female preponderance may be due to difficulty identifying the disorder in males. Disagreement among mental-health professionals about how this illness appears clinically and controversy about whether DID even exists adds to the difficulty of estimating how often it occurs.
Some professionals continue to be of the opinion that DID does not exist. The nature of this skepticism is sometimes due to questions about why many more individuals who have endured the stress of terrible abuse as young children do not develop the disorder, why more children are not diagnosed as having DID, and why some DID sufferers have no history of significant trauma. One explanation for what some believe to be these inconsistencies is that given the highly complex and unknown nature of the human brain and psyche, many of those whom one would expect to develop dissociative identity disorder are spared due to their resilience. Another concern about the diagnosis of DID involves having to rely on the traumatic memories of those who suffer from this disorder. That DID is significantly more often assessed in individuals in North America compared to the rest of the world, for the most part, leads some practitioners to believe that DID is a culture-based concoction rather than a true condition. As with many other mental health issues, symptoms of the same disorder in children look very different than symptoms in adults. Studies that verify the presence of DID using multiple resources add credibility to the diagnosis. Research on individuals with DID that have little to no media exposure to information on the illness lends further credibility to the reliability of the existence of this mental health condition.
Although there was a case study of DID as early as 1906, movies about DID first became well known in the United States in the 1950s. The 1953 movie The Three Faces of Eve tells the story of Chris Sizemore, a real-life woman with the disorder. She was thought to develop DID in reaction to witnessing several terrible accidents at a young age. That movie described three personalities that were successfully merged or integrated into one within one year. More accurately, the person depicted in that movie reportedly had to contend with 22 personalities that took more than 45 years to be able to coexist in a functional way. A television miniseries about DID was Sybil. The character of Sybil Dorsett portrayed the life story of Shirley Ardell Mason, who experienced severe physical, emotional, and sexual abuse that was inflicted by her mother. She was thought to develop 16 distinct identities. As with the diagnosis in general, the veracity of the story of Sybil remains a controversy, with claims that the illness in general, and Sybil specifically, is a hoax.
How do health-care professionals diagnose dissociative identity disorder?
There is no specific definitive test, like a blood test, that can accurately assess that a person has dissociative identity disorder. Therefore, mental-health practitioners like psychiatrists, psychoanalysts, or clinical psychologists conduct a mental-health interview that gathers information, looking for the presence of the signs and symptoms previously described.
The diagnostic criteria for dissociative identity disorder are as follows:
- The presence of two or more distinct identities or personality states (each with its own relatively persistent pattern of perceiving, relating to, and thinking about him or herself and the world)
- At least two of the identities or personality states repeatedly take control of the person's behavior.
- An inability to recall important personal information that is too severe to be explained by ordinary forgetfulness
- The illness is not the result of the direct physiological effects of a substance (for example, blackouts or other abnormal behavior during alcohol or other drug intoxication) or a general medical condition (for example, seizures). In children, the symptoms are not caused by imaginary playmates or other fantasy play.
Professionals usually gather information about the individual's childhood and ask questions to explore whether the symptoms that the client is suffering from are not better accounted for by another mental-health condition, dissociative or otherwise. Other types of dissociative disorders include depersonalization disorder (feeling detached from themselves or surroundings), dissociative amnesia (memory problems associated with a traumatic experience), dissociative fugue (abandonment of familiar surroundings and memory lapse for the past), and dissociative disorder, not otherwise specified (episodes of dissociation that do not qualify for one of the specific dissociative disorders just described). As part of the assessment, mental health professionals also usually ask about other mental conditions and ensure that the person has recently received a comprehensive physical examination and any appropriate medical tests so that any physical conditions that may mimic symptoms of DID are identified and addressed.
Dissociation, a major symptom of DID, is known to occur in a number of other mental illnesses. For example, an individual with this disorder may seek to relieve overwhelming memories of trauma by engaging in the self-mutilation and other forms of self-harm and self-destructive behaviors that tends to be found in those with borderline personality disorder. Also, feelings and behaviors that may appear to be caused by dissociation, but are not, make it all the more difficult to distinguish DID from other conditions. Somatization disorder, psychogenic amnesia, psychogenic fugue, conversion disorder, and schizophrenia are just a few such disorders. Rape and other adult trauma victims have been found to be quite vulnerable to developing dissociative symptoms. The controversy about whether DID exists, as well as the overlap of symptoms it has with a number of other conditions, sometimes results in misdiagnosis.
Symptoms of some other mental disorders may be mistaken for dissociation. The apparent impulsivity of bipolar disorder or wide mood swings associated with bipolar disorder or with narcissistic personality disorder when triggered by minor slights are two such examples. Blackouts that can be related to substance use disorders are other instances of an individual being unaware of his or her surroundings that mimics dissociation.
DID often co-occurs with other emotional conditions, including posttraumatic stress disorder (PTSD), borderline personality disorder (BPD), and a number of other personality disorders, as well as conversion disorder. DID is sometimes feigned by individuals who may be seeking attention, as in Munchausen's syndrome. It has also been appropriately diagnosed as well as feigned in individuals involved in the criminal justice and civil or family court systems (for example, forensic cases). Adding to the diagnostic difficulty is that people like pedophiles and other sex offenders, as well as people with antisocial personality disorder, may legally stand to gain from having DID. While some of those individuals may feign the diagnosis in an effort to benefit legally, others genuinely suffer from significant dissociative symptoms, as well as full-blown DID. In cases where there may be an ulterior motive for being diagnosed with DID, studies show that using a screening test or structured interview may be the best way to determine if the person truly suffers from this condition.
What are the treatment methods for dissociative identity disorder?
Psychotherapy is generally considered to be the main component of treatment for dissociative identity disorder. In treating individuals with DID, therapists usually try to help clients improve their relationships with others and to experience feelings they have not felt comfortable being in touch with or openly expressing in the past. This may be done using individual, family, and/or group psychotherapy. It is carefully paced in order to prevent the person with DID from becoming overwhelmed by anxiety, risking a figurative repetition of their traumatic past being inflicted by those very strong emotions. Dialectical behavior therapy is a form of cognitive behavior therapy that emphasizes mindfulness and works on helping the DID sufferer soothe him- or herself by decreasing negative responses to stressors.
Mental health professionals also often guide clients in finding a way to have each aspect of them coexist, and work together, as well as developing crisis-prevention techniques and finding ways of coping with memory lapses that occur during times of dissociation. The goal of achieving a more peaceful coexistence of the person's multiple personalities is quite different than the reintegration of all those aspects into just one identity state. While reintegration used to be the goal of psychotherapy, it has frequently been found to leave individuals with DID feeling as if the goal of the practitioner is to get rid of, or "kill," parts of them.
Hypnosis is sometimes used to help increase the information that the person with DID has about their symptoms/identity states, thereby increasing the control they have over those states when they change from one personality state to another. That is said to occur by enhancing the communication that each aspect of the person's identity has with the others. In this age of insurance companies regulating the health care that most Americans receive, having time-limited, multiple periods of psychotherapy rather than intensive long-term care provides what may be another effective treatment option for helping people who are living with DID.
Eye movement desensitization and reprocessing (EMDR), a type of treatment that integrates traumatic memories with the patient's own resources, is being increasingly used in the treatment of people with dissociative identity disorder. It has been found to result in enhanced information processing and healing.
Medications are often used to address the many other mental health conditions that individuals with DID tend to have, like depression, severe anxiety, anger, and impulse-control problems. However, particular caution is appropriate when treating people with DID with medications because any effects they may experience, good or bad, may cause the sufferer of DID to feel like they are being controlled, and therefore traumatized yet again. As DID is often associated with episodes of severe depression, electroconvulsive therapy (ECT) can be a viable treatment when the combination of psychotherapy and medication does not result in adequate relief of symptoms.
