[Two types of depersonalization--reconsideration from a descriptive-phenomenological view point].
The term depersonalization has been vaguely used in clinical contexts and there is confusion over its nosological positioning. Although the syndrome has been assigned a niche of its own in the European psychiatric taxonomy, the American's Diagnostic and Statistical Manual of Mental Disorders (DSM-III, IV) labeled it under the term Dissociative Disorder. The latter, which does not agree with the classical theory of Janet, seems to have no basis on traditional psychopathology and is not derived from any dissociative theories. In this paper the descriptive characteristics of depersonalization are discussed with regard to the features of "observing self" and the relationship between experiences and selves, according to which the authors distinguish two types of depersonalization: an "excessive-self-reflecting type" and an "absorbed-in-experience type". Whereas the former coinsides with the typical depersonalization neurosis, in which excessive self-reflection plays an important role in reducing the sense of reality, in the latter over-absorption in some situations leads the patient to construct a wall to block out reality. We suggest that in making a distinction between these two types, the psychopathology of depersonalization will be better clarified.

Dissociative experiences and disorders among women who identify themselves as sexual abuse survivors.
The purpose of the study was to identify dissociative experiences and disorders among women who are survivors of sexual abuse. Fifty-one women from two different centers who identified themselves as abuse survivors participated in the research interviews. The Dissociative Experiences Scale (DES) and the Dissociative Disorders Interview Schedule (DDIS) were used to collect data. The results indicated that 88.2% of the 51 women had a dissociative disorder of some type. Twenty-eight (54.9%) of the women had a DDIS diagnosis of multiple personality disorder (MPD). The women had high DES scores, a high number of secondary features of MPD, high rates of depression, borderline personality, substance abuse, somatic symptoms, Schneiderian symptoms, ESP/supernatural experiences, suicide attempts, and conversion symptoms. The vast majority of sexual abuse survivors in this sample have extensive dissociative symptomatology and related features. Therapists working with adult sexual abuse survivors should be knowledgeable about dissociation, should thoroughly assess a client's dissociative abilities, and should incorporate these findings into the therapy process.

Art and multiple personality disorder: an expressive framework for occupational therapy.
Patients with multiple personality and dissociative disorders have learned to create an alternate identity system, originally designed to protect them from experiencing the pain of inescapable, unrelieved trauma and abuse. The resulting amnesia and identity confusion cause significant dysfunction in daily living. Issues of trust and control are paramount, and occupational therapists are challenged with the task of engaging these patients in meaningful activity. Although these patients often avoid structured groups, they have generally been responsive to expressive art opportunities as an initial activity. This paper outlines an expressive framework by which occupational therapists can therapeutically manage the artwork behaviors of the patient with dissociative or multiple personality disorder. The material presented is based on clinical observation of more than a dozen patients with multiple personality disorder in various stages of recovery and of many persons with dissociative trauma who may have multiple personality disorder. These observations took place within an acute care, inpatient occupational therapy setting. Guidelines for the creation of a positive working alliance and therapeutic climate for self-expression are outlined, and a progressive model for the viewing of patients' art products is described.

Analysis of psychiatric morbidity of outpatient children in Mitford Hospital, Dhaka.
The objective of this study was to describe the pattern of psychiatric morbidity among 97 child patients who, for the first time attended the psychiatric outpatient department of Sir Salimullah Medical College & Mitford Hospital, Dhaka, in the year 1994. Dissociative disorder (Hysteria) comprised the largest group (21.65%), followed by epilepsy (19.59%). Majority of the cases were within 7-10 years age group with mean age 9.74 (+/- 2.39) years. Male outnumbered female patients and 53.61% cases came from rural background. The findings of the study indicate the need for establishment of child psychiatric treatment centres in different parts of the country including rural areas.

Relationship of parental bonding to child abuse and dissociation in eating disorders in Japan.
Parental bonding patterns were studied in 52 female Japanese eating disorder outpatients with and without histories of sexual or physical abuse and with dissociation. Instruments included the Parental Bonding Instrument (PBI), the Dissociative Experiences Scale (DES) and the Dissociative Disorders Interview Schedule (DDIS). Those with physical abuse history, but not sexual abuse history, had significantly different parental bonding scores and higher DES scores compared with subjects without physical abuse. DES scores and PBI scores were not correlated. Although the PBI was useful in discriminating between those with and those without abuse histories, it did not detect differences in degree of dissociation. Lack of association of sexual abuse to PBI and DES scores may have been due to mild abuse.

Psychogenic or dissociative fugue: a clinical investigation of five cases.
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.

The role of childhood interpersonal trauma in depersonalization disorder.
OBJECTIVE: In contrast to trauma's relationship with the other dissociative disorders, the relationship of trauma to depersonalization disorder is unknown. The purpose of this study was to systematically investigate the role of childhood interpersonal trauma in depersonalization disorder. METHOD: Forty-nine subjects with DSM-IV depersonalization disorder and 26 healthy comparison subjects who were free of lifetime axis I and II disorders and of comparable age and gender were administered the Dissociative Experiences Scale and the Childhood Trauma Interview, which measures separation or loss, physical neglect, emotional abuse, physical abuse, witnessing of violence, and sexual abuse. RESULTS: Childhood interpersonal trauma as a whole was highly predictive of both a diagnosis of depersonalization disorder and of scores denoting dissociation, pathological dissociation, and depersonalization. Emotional abuse, both in total score and in maximum severity, emerged as the most significant predictor both of a diagnosis of depersonalization disorder and of scores denoting depersonalization but not of general dissociation scores, which were better predicted by combined emotional and sexual abuse. The majority of the perpetrators of emotional abuse were either or both parents. Although different types of trauma were modestly correlated, only a few of these relationships were statistically significant, underscoring the importance of comprehensively considering different types of trauma in research studies. CONCLUSIONS: Childhood interpersonal trauma and, in particular, emotional abuse may play a role in the pathogenesis of depersonalization disorder. Compared to other types of childhood trauma, emotional maltreatment is a relatively neglected entity in psychiatric research and merits more attention.

Dissociation in alternative healers and traditional therapists: a comparative study.
Nineteen psychiatry residents were compared to 12 community-based alternative healers on the Dissociative Experiences Scale and the Dissociative Disorders Interview Schedule. Neither group showed evidence of extensive psychopathology. However, the alternative healers reported more Schneiderian symptoms, extrasensory experiences, and secondary features of multiple personality disorder. Among the healers, these experiences did not seem to be indicative of psychopathology, and were in fact valued and sought after. Dissociative experiences are not necessarily indicators of psychiatric disorder in nonclinical groups.

One brain, two selves.
Having a sense of self is an explicit and high-level functional specialization of the human brain. The anatomical localization of self-awareness and the brain mechanisms involved in consciousness were investigated by functional neuroimaging different emotional mental states of core consciousness in patients with Multiple Personality Disorder (i.e., Dissociative Identity Disorder (DID)). We demonstrate specific changes in localized brain activity consistent with their ability to generate at least two distinct mental states of self-awareness, each with its own access to autobiographical trauma-related memory. Our findings reveal the existence of different regional cerebral blood flow patterns for different senses of self. We present evidence for the medial prefrontal cortex (MPFC) and the posterior associative cortices to have an integral role in conscious experience.

Dissociative experiences and psychopathology in conversion disorders.
The concepts of dissociation and conversion are historically linked with the first psychodynamic ideas on hysteria. However, the abolition of "hysterical neurosis" from current nosology has led to independent developments of these theoretical models. Recent studies found a high degree of somatization in dissociative disorders. However, little is known about dissociation in conversion disorders. We assessed 72 patients with conversion disorders for their dissociative and general psychopathology using the German version of the Dissociative Experience Scale (DES) and the Symptom Check List (SCL-90-R). They were compared with a control group of 96 psychiatric patients suffering from various neurotic disorders, who were matched for gender and age. Dissociative symptoms were significantly more frequent in conversion disorder patients than in controls. There were no differences in the SCL-90-R scores between the two groups. Our findings support the theory of similar psychological processes underlying conversion and dissociative disorders despite their descriptive differences.

Childhood sexual abuse and psychosomatic symptoms in irritable bowel syndrome.
Irritable bowel syndrome is characterized by chronic gastrointestinal symptoms without a demonstrable physical cause. In a subgroup of patients, irritable bowel syndrome may be part of a cluster of psychosomatic symptoms related to childhood sexual abuse. To investigate this possibility, the Dissociative Disorders Interview Schedule (DDIS), the Dissociative Experiences Scale (DES) and the Symptom Checklist-90 (SCL-90) were administered to 105 subjects with either irritable bowel syndrome, inflammatory bowel disease (Crohn's disease or ulcerative colitis), or other gastrointestinal disorders. The subjects in the three groups did not differ on the DES, the SCL-90 or most sections of the DDIS. However, subjects with irritable bowel syndrome reported much higher rates of childhood sexual abuse and psychosomatic symptoms.

Childhood trauma and dissociative symptoms in panic disorder.
OBJECTIVE: Childhood trauma has been associated with increased risk for both panic disorder and dissociative symptoms in adulthood. The authors hypothesized that among individuals with a primary diagnosis of panic disorder, those experiencing depersonalization/derealization during panic attacks would be more likely to have a history of childhood trauma. METHOD: Rates of traumatic events were compared between panic disorder patients with (N=34) and without (N=40) prominent depersonalization/derealization during panic attacks. Symptom severity in the two groups was also examined. RESULTS: Contrary to the authors' hypothesis, no evidence was found that depersonalization/derealization during panic attacks was associated with childhood trauma. Minimal differences in severity of illness were found between patients with dissociative symptoms and those without such symptoms. CONCLUSIONS: This finding is consistent with a multifactorial model of dissociation. Factors other than childhood trauma and general psychopathology may underlie vulnerability to dissociative symptoms in panic disorder.

Relationship of personality to dissociation and childhood trauma in borderline personality disorder.
BACKGROUND: Dissociation is a prominent feature in some individuals with borderline personality disorder (BPD), yet our understanding of the meanings and implications of prominent dissociation in BPD remains limited. The purpose of this study was to investigate the relationship between dissociation and childhood trauma in BPD and to explore the relationships of dissociation and trauma to various personality features of BPD. METHODS: Twenty BPD subjects and 24 healthy comparison subjects of similar age and gender were administered the Dissociative Experiences Scale, the Childhood Trauma Questionnaire-short form, the Tridimensional Personality Questionnaire, the Defense Style Questionnaire, the Relationship Style Questionnaire, and the Schema Questionnaire. RESULTS: The BPD group exhibited greater dissociation and childhood trauma, as well as greater pathology in most personality variables, compared with the healthy group. Dissociation in BPD was not significantly related to total childhood trauma, but only to emotional neglect, which accounted for 23% of the variance in dissociation scores. CONCLUSION: Within the BPD group, dissociation was associated with fearful attachment and immature defenses, while total childhood trauma and emotional neglect were associated with overconnection and disconnection schemata. This is a preliminary study with a small sample size, yet the correlates of dissociation in BPD merit further investigation.

Basal norepinephrine in depersonalization disorder.
In contrast to the noradrenergic dysregulation described in PTSD, little is known regarding noradrenergic function in dissociative disorders. The purpose of this preliminary study was to investigate basal norepinephrine in depersonalization disorder (DPD). Nine subjects with DSM-IV DPD, without lifetime PTSD, were compared to nine healthy comparison (HC) subjects. Norepinephrine was measured via 24-h urine collection and three serial plasma determinations. Groups did not differ significantly in plasma norepinephrine levels. Compared to the HC group, the DPD group demonstrated significantly higher urinary norepinephrine, only prior to covarying for anxiety. The DPD group also demonstrated a highly significant inverse correlation between urinary norepinephrine and depersonalization severity (r=-0.88). Norepinephrine and cortisol levels (reported in a prior study) were not intercorrelated. We concluded that although dissociation accompanied by anxiety was associated with heightened noradrenergic tone, there was a marked basal norepinephrine decline with increasing severity of dissociation. The findings are in concordance with the few reports on autonomic blunting in dissociation and merit further investigation.

Dissociation as complex adaptation.
In this article the general theory of complex adaptive systems, substantiated by non-linear dynamics, will be used to put the dissociative disorders into a theoretical framework and clarify their genesis and presentation. When a system is far out of equilibrium, dissipative structures may be formed ('order out of chaos', as Prigogine (1) has put it). These structures provide the starting point for further evolution and co-evolution of competing groups of functional schemata divided on a bifurcation surface. Complex adaptation is almost inevitable in a complicated system (such as the brain) driven by non-linear dynamics. Dissociation is thus regarded as a consequence of adaptation to a chaotic environment rich in contrasts. In a sufficiently complex environment a person with dissociative identity disorder is more adapted and thus more likely to occur than a 'normal' monopersonality individual.

Affective predictors of dissociation. II: Shame and guilt.
As a contribution to an understanding of the psychodynamics of dissociative disorders this study investigated proneness to shame and to guilt as predictors of dissociative tendencies. One hundred and three Australian university students completed self-report measures of dissociative tendencies, proneness to shame and to guilt, gender, and age. Proneness to shame, proneness to guilt, and age were found to contribute significantly to the prediction of dissociative tendencies. The data provide further support for the view that common affective consequences of childhood trauma may mediate between such trauma and the development of a dissociative coping style.
