The authors review the co-occurrences of dissociative symptoms and disorders with epilepsy and pseudo-seizures and examine newer diagnostic instruments that assist in accurate diagnosis of persons with concomitant seizure behaviors and dissociative symptoms. They also review seizure behaviors and electroencephalographic findings in persons with dissociative identity disorder (DID) and dissociative disorder not otherwise specified (DDNOS) and dissociative symptoms in persons with epilepsy and with pseudoseizures. Dissociative symptoms in 15 patients with epilepsy and 15 with pseudo-seizures were examined using the Dissociative Experiences Scale (DES) and the Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D). On the SCID-D, pseudo-seizure patients had significantly higher dissociative symptom scores than epileptic patients, but DES scores did not reliably distinguish epileptic and pseudo-seizure patients. Misdiagnosis of persons with seizures and dissociative symptoms can be avoided by careful adherence to DSM dissociative disorder criteria, the use of video-EEG monitoring, and systematic assessment of dissociative symptoms with the SCID-D.

Dissociative fugue (formerly psychogenic fugue) is a rare and little understood dissociative disorder. Following a review of the pertinent literature, five cases of dissociative fugue are described. These cases were systematically studied with a comprehensive history, mental status examination, physical and neurological evaluation, review of previous medical and psychiatric records, and psychological testing including MMPI, WAIS-R, electroencephalogram, and Dissociative Experiences Scale. An unexpected finding was that, in some cases, associated criminal activity may allow the person with dissociative fugue to continue to function in spite of their loss of memory and original identity.

A wide variety of dissociative disorders, including dissociative amnesia, dissociative fugue, depersonalization disorder, dissociative identity disorder, and various forms of dissociative disorder not otherwise specified. In many instances, these disorders are either underdiagnosed or misdiagnosed secondary to the clinician's mistaken belief that dissociative disorders are rare. Recent research shows that dissociative disorders may comprise 5% to 10% of psychiatric populations. This article reviews the epidemiology and clinical symptomatology of these disorders. In addition, various screening and diagnostic instruments, such as the DES, Structured Clinical Interview for Dissociative Disorders, and MMPI, are discussed.

Research has consistently found elevated mean dissociation scores in particular diagnostic groups. In this study, we explored whether mean dissociation scores for different diagnostic groups resulted from uniform distributions of scores within the group or were a function of the proportion of highly dissociative patients that the diagnostic group contained. A total of 1566 subjects who were psychiatric patients, neurological patients, normal adolescents, or normal adult subjects completed the Dissociative Experience Scale (DES). An analysis of the percentage of subjects with high DES scores in each diagnostic group indicated that the diagnostic group's mean DES scores were a function of the proportion of subjects within the group who were high dissociators. The results contradict a continuum model of dissociation but are consistent with the existence of distinct dissociative types.

The diagnostic validity of multiple personality disorder (MPD) and its association to trauma have been questioned because corroboration of child abuse in studies of patients with MPD is scant. The purpose of this study was to determine on a retrospective basis whether external corroboration of child abuse could be found in a group of patients with MPD and dissociative disorder not otherwise specified. A group of child and adolescent psychiatric inpatients and outpatients was chosen because of the extensive number of collateral records collected on them in a tertiary care setting. This group was also chosen because of the intense interest paid by child protective services and courts to child abuse during the past 15 years. This retrospective chart review confirmed child abuse in eight of nine patients with MPD and in all 12 cases of dissociative disorder not otherwise specified. This study provides further evidence of the association of severe dissociative disorders with trauma, particularly child abuse. Future studies should be prospective and blinded to avoid the possibility of investigator bias, and should include a control group for comparison of base rate of child abuse.

MMPI special scales were repeatedly administered to several personality states of a woman alleging to have Multiple Personality Disorder. Her inability to produce a consistent response set on retesting helped to unmask a case of factitious multiple personality.

OBJECTIVE: The Dissociative Experiences Scale has proved a reliable and valid instrument to measure dissociation in many groups, but its capacity to distinguish patients with multiple personality disorder from patients with other psychiatric disorders has not yet been conclusively tested. METHOD: A discriminant analysis was performed to classify 1,051 subjects as having or not having multiple personality disorder. Another discriminant analysis was performed on a subgroup of 883 subjects more closely representing patients in a typical psychiatric facility in terms of base rates of dissociative disorders. A cutoff score of 30 was also used to classify subjects, and Bayes's theorem, which allows for the calculation of the positive predictive value and the negative predictive value of a screening test, was applied. RESULTS: According to discriminant analysis of the total study group, the scale's sensitivity was 76% and its specificity was also 76%; according to discriminant analysis of the more representative subgroup, the scale's sensitivity was 76% and its specificity was 85%. Use of the cutoff score of 30 produced similar results. Results of the application of Bayes's theorem showed that 17% of the subjects scoring 30 or higher would actually have multiple personality disorder and 99% of those scoring less than 30 would not have multiple personality disorder. CONCLUSIONS: These results indicate that the Dissociative Experiences Scale performs quite well as a screening instrument to identify subjects with multiple personality disorder. In addition, the consistency of responses to scale items across centers indicates that the symptoms reported by patients with multiple personality disorder are highly similar across diverse geographic centers. This consistency supports the reliability and validity of the diagnosis of multiple personality disorder across centers.

The psychiatric literature generally discourages the use of electroconvulsive therapy (ECT) to treat depression in dissociative disorder patients, but contains little data on outcome. This prospective study of ECT in three dissociative disorder patients demonstrates that ECT is indicated for severe treatment-resistant depression in such patients. Their Hamilton Depression Scale scores fell by 50%, they were remarkably clinically improved, and they maintained their gains for at least 4 months. The ECT proved helpful when depression was felt by most of the active alters rather than just by one depressed personality. Mini-Mental State Examination scores and clinical observation revealed no unusual confusion or side effects from ECT. These patients' dissociated condition was not altered by ECT, which indicates that ECT neither treats nor impairs treatment of dissociation. Electroconvulsive therapy can be helpful in the overall treatment of dissociative disorders by alleviating severe depressions which block utilization of psychotherapy.

In this article I have addressed the possibility of iatrogenesis and/or malingering of MPD in 19 individuals who were charged with homicide. Due to the fragmentary nature of most of these case reports, it is not possible to state definitively who had genuine MPD and who did not. There is a strong possibility that a substantial proportion were malingering, however, because of their rather atypical presentations. Data from other sources suggest that the use of hypnosis in individuals accused of homicide may iatrogenically produce MPD-like phenomena when coupled with the defendant's desire to escape criminal responsibility. Finally, I have offered guidelines for the forensic evaluation of homicide defendants in whom MPD is suspected. Although hypnosis should generally be avoided in such defendants if it is used, rather strict guidelines should be followed. Clinicians using hypnosis with such individuals should be forewarned that such use will be strongly challenged in court and could pose an extreme threat to the defense position.

We present the first report of multiple personality disorder (MPD) in a prelingually deaf patient and the first description of alter personalities as the source of auditory hallucinations in a nonpsychotic deaf person. This young woman's history and clinical symptoms of MPD did not differ from those of hearing patients. A hypnotic trance was induced by instructing the patient in muscle relaxation, modeling relaxation with exhalation, and having the patient focus her gaze on the hypnotist repeatedly fingerspelling R-E-L-A-X. Hypnosis facilitated automatic handwriting, allowed the first meeting with an alter personality, and speeded the diagnostic process. Fingerspelling has not previously been reported in hypnosis of the deaf. It is a practical means of induction for a therapist who lacks fluent signing skills. It provides a narrow fix of gaze and avoids induction by physical stimulation, a process that some abused patients find upsetting.

A number of previous studies have delineated Minnesota Multiphasic Personality Inventory (MMPI) characteristics in patients with multiple personality. To test the accuracy of the MMPI in identifying such patients, the authors blindly rated 63 MMPIs as being either multiple personality or not. The over-all hit rate for the entire sample was 71.4%, with a 68% hit rate for correctly identified patients with multiple personality. These hit rates compare favorably with the hit rates in similar studies of other psychiatric disorders and further demonstrate the clinical usefulness of the MMPI in the diagnosis of multiple personality.
