The implication that the change in nomenclature from “Multiple Personality Disorder” to “Dissociative Identity Disorder” means the condition has been repudiated and “dropped” from the Diagnostic and Statistical Manual (DSM) of the American Psychiatric Association is false and misleading. Many if not most diagnostic entities have been renamed or have had their names modified as psychiatry changes in its conceptualizations and classifications of mental illnesses. When the DSM decided to go with “Dissociative Identity Disorder” it put “(formerly multiple personality disorder)” right after the new name to signify that it was the same condition. It’s right there on page 526 of DSM-IV-R. There have been four different names for this condition in the DSMs over the course of my career. I was part of the group that developed and wrote successive descriptions and diagnostic criteria for this condition for DSM-III-R, DSM–IV, and DSM-IV-TR.While some patients have been hurt by the impact of material that proves to be inaccurate, there is no evidence that scientifically demonstrates the prevalence of such events. Most material alleged to be false has been disputed by someone, but has not been proven false.Finally, however intriguing the idea of encouraging forgetting troubling material may seem, there is no evidence that it is either effective or safe as a general approach to treatment. There is considerable belief that when such material is put out of mind, it creates symptoms indirectly, from “behind the scenes.” Ironically, such efforts purport to cure some dissociative phenomena by encouraging others, such as Dissociative Amnesia.
The case of a patient with dissociative identity disorder follows:Cindy, a 24-year-old woman, was transferred to the psychiatry service to facilitate community placement. Over the years, she had received many different diagnoses, including schizophrenia, borderline personality disorder, schizoaffective disorder, and bipolar disorder. Dissociative identity disorder was her current diagnosis.Cindy had been well until 3 years before admission, when she developed depression, "voices," multiple somatic complaints, periods of amnesia, and wrist cutting. Her family and friends considered her a pathological liar because she would do or say things that she would later deny. Chronic depression and recurrent suicidal behavior led to frequent hospitalizations. Cindy had trials of antipsychotics, antidepressants, mood stabilizers, and anxiolytics, all without benefit. Her condition continued to worsen.Cindy was a petite, neatly groomed woman who cooperated well with the treatment team. She reported having nine distinct alters that ranged in age from 2 to 48 years; two were masculine. Cindy’s main concern was her inability to control the switches among her alters, which made her feel out of control. She reported having been sexually abused by her father as a child and described visual hallucinations of him threatening her with a knife. We were unable to confirm the history of sexual abuse but thought it likely, based on what we knew of her chaotic early home life.Nursing staff observed several episodes in which Cindy switched to a troublesome alter. Her voice would change in inflection and tone, becoming childlike as ]oy, an 8-year-old alter, took control. Arrangements were made for individual psychotherapy and Cindy was discharged.At a follow-up 3 years later, Cindy still had many alters but was functioning better, had fewer switches, and lived independently. She continued to see a therapist weekly and hoped to one day integrate her many alters.
Readers acquainted with the recent literature on human sexuality will be familiar with what we call the standard narrative of human sexual evolution, hereafter shortened to the standard narrative. It goes something like this:1. Boy Meets girl, 2. Boy and girl assess one and others mate value, from perspectives based upon their differing reproductive agendas/capacities. He looks for signs of youth, fertility, health, absence of previous sexual experience and likelihood of future sexual fidelity. In other words, his assessment is skewed toward finding a fertile, healthy young mate with many childbearing years ahead and no current children to drain his resources. She looks for signs of wealth (or at least prospects of future wealth), social status, physical health and likelihood that he will stick around to protect and provide for their children. Her guy must be willing and able to provide materially for her (especially during pregnancy and breastfeeding) and their children, known as "male parental investment". 3. Boy gets girl. Assuming they meet one and others criteria, they mate, forming a long term pair bond, "the fundamental condition of the human species" as famed author Desmond Morris put it. Once the pair bond is formed, she will be sensitive to indications that he is considering leaving, vigilant towards signs of infidelity involving intimacy with other women that would threaten her access to his resources and protection while keeping an eye out (around ovulation especially) for a quick fling with a man genetically superior to her husband. He will be sensitive to signs of her sexual infidelities which would reduce his all important paternity certainty while taking advantage of short term sexual opportunities with other women as his sperm are easily produced and plentiful. Researchers claim to have confirmed these basic patterns in studies conducted around the world over several decades. Their results seem to support the standard narrative of human sexual evolution, which appears to make a lot of sense, but they don't, and it doesn't.
