Depersonalization is discussed and a brief outline of the primary symptoms is presented. The relationship between obsessionalism and depersonalization is reviewed in the literature, and subsequent similarities are presented. The intellectual obsessive depersonalization syndrome is postulated as a variant, and also as an exposition of what might occur in many other cases of depersonalization. Finally, a picture is presented which takes into account a strong component of obsessionalism in both the etiology and course of depersonalization.

A transient depersonalization syndrome was identified in nearly one third of persons exposed to life-threatening danger (accident victims) and close to 40% of a group of hospitalized psychiatric patients. Although the syndrome was similar in these populations, mental clouding developed more commonly among patients and alertness was more prominent among accident victims. Anxiety was significantly associated with the development of depersonalization among psychiatric patients and was almost certainly a factor in its appearance among accident victims. The findings suggest that this syndrome is a specific response to extreme danger or its associated anxiety.

Depersonalization disorder is classified in DSM-III-R (APA 1987) as a dissociative disorder characterized by altered perception or experience of the self. To date, there are no known reports of the neurobiological features of this disorder. We report clinical and biological correlates in a patient with depersonalization disorder previously unresponsive to a variety of anticonvulsant, monoamine oxidase inhibitor, and tricyclic antidepressant trials, but for whom fluoxetine partially reduced depersonalization symptoms, but not associated anxiety and depression. Neurophysiological, neuroanatomical and neuropsychological findings revealed left hemispheric frontal-temporal activation and decreased left caudate perfusion. These findings suggest a similarity to the neuropsychiatric data reported in obsessive-compulsive disorder patients.

Eight patients with depersonalization disorder or with depersonalization symptoms in association with obsessive-compulsive and panic disorders were treated with serotonin reuptake blockers. There was clinical overlap of depersonalization disorder with obsessive-compulsive disorder, and the co-occurrence of obsessive-compulsive and panic features with depersonalization in these patients was associated with a favorable treatment outcome. The chronicity of illness and lack of prior response to a variety of treatments in these patients highlights the positive outcome with this treatment. In addition, issues are raised regarding the current hierarchical exclusion of depersonalization disorder in the presence of obsessive-compulsive and panic disorders.

From a review of the literature on meditation and depersonalization and interviews conducted with six meditators, this study concludes that: 1) meditation can cause depersonalization and derealization; 2) the meanings in the mind of the meditator regarding the experience of depersonalization will determine to a great extent whether anxiety is present as part of the experience; 3) there need not be any significant anxiety or impairment in social or occupational functioning as a result of depersonalization; 4) a depersonalized state can become an apparently permanent mode of functioning; 5) patients with Depersonalization Disorder may be treated through a process of symbolic healing--that is, changing the meanings associated with depersonalization in the mind of the patient, thereby reducing anxiety and functional impairment; 6) panic/anxiety may be caused by depersonalization if catastrophic interpretations of depersonalization are present.

Primary depersonalization disorder is believed to be resistant to treatment. However, we report the successful treatment of a case with desipramine and suggest that, because there is a link between depersonalization and anxiety disorders, tricyclic antidepressants may prove effective for depersonalization.

Depersonalization is a subjective sense of unreality regarding various aspects of the self, experienced as disconnectedness from one's own body, mentations, feelings, or actions. When episodes of depersonalization are recurrent or persistent and lead to distress or dysfunction, the diagnosis of depersonalization disorder is made. Certain similarities in phenomenology, comorbidity, neurochemistry, and treatment response suggest a relationship to the obsessive-compulsive spectrum. However, depersonalization is a very poorly studied condition, and any conclusions must be viewed tentatively. Self-injurious behaviors are defined as intentionally self-inflicted bodily injuries without lethal intent. Basic categories are briefly described. Subsequently, the phenomenology and biology of both impulsive and compulsive self-injurious behaviors, and their relationship to the obsessive-compulsive spectrum, are discussed.

The comparison of psychopathological and age characteristics of depersonalization was made for 114 schizophrenic patients. It has been concluded that depersonalization syndrome may be viewed as a developmental or dysontogenetic disorder of self-consciousness. In the majority of the cases depersonalization arises in adolescence which is the most critical period in the development of self-consciousness. Typical psychopathological features of depersonalization correspond to typical features of puberty identity crisis.

Using the criteria of the Structured Clinical Interview for DSM-III-R Dissociative Disorders (SCID-D), we assessed the incidence of feelings of unreality among a sample of 70 persons who had sustained head injuries. Among those whose head trauma could be classified as mild, more than 60% complained of a depersonalization syndrome. Among those with a significant period of unconsciousness, only 11% had similar complaints. There was a high comorbidity with post-traumatic stress disorder and vertigo. Feelings of unreality were not associated with cognitive impairment or elevated personality test scores, nor were there significant relationships with gender or involvement in litigation. A conservative estimate of incidence of depersonalization among persons with minor head trauma is 13%, while, at the upper end, as many as 67% of persons who sustain mild head injury may experience feelings of unreality.

Depersonalization disorder comprises one of the four major dissociative disorders and yet remains poorly studied. There are no reports describing the application of dissociation scales to this population. Our goal was to investigate the applicability of four such scales to depersonalization disorder and to establish screening criteria for the disorder. Two general dissociation scales and two depersonalization scales were administered to 50 subjects with DSM-III-R depersonalization disorder and 20 healthy control subjects. The depersonalization disorder group scored significantly higher than the normal control group in all scales and subscales. Factor analysis of the Dissociative Experiences Scale (DES) yielded three factors as proposed previously, absorption, amnesia, and depersonalization/derealization. A DES cutoff score of 12, markedly lower than those previously proposed for the screening of other dissociative disorders, is required for the sensitive detection of depersonalization disorder. Alternatively, the DES pathological dissociation taxon (DES-taxon) score recently generated in the literature appears more sensitive to the detection of depersonalization disorder and is better recommended for screening purposes. The other three scales were fairly strongly correlated to the DES, suggesting that they may measure similar but not identical concepts, and cutoff scores are proposed for these scales also. General implications for the screening and quantification of depersonalization pathology are discussed.
