摘要:

The editors first describe the principal symptoms of the Capgras delusion, the Frégoli delusion, the delusion of intermeta-morphosis and the delusion of subjective doubles before developing the argument that it would be appropriate for international psychiatric diagnostic systems to include these disorders. Furthermore the similarity between them, the reduplicative paramnesias and déjà and jamais vu are pointed out. By stressing a symptom-based approach it is possible to examine psychiatric, neurological and medical cases as arising from the same underlying disturbance in cognition function. The relationship between delusions of misidentification and other delusions is also touched upon.

摘要:

Since the publication of the seminal paper by Capgras and Reboul-Lachaux more than a dozen varieties of delusional misidentification have been reported in the psychiatric and neurological literature. Although subjected to increasingly sophisticated scrutiny, continuing confusion and disagreement over terminology, delineation of phenomenology and nosology hamper the systematic study of these phenomena.

摘要:

The delusional misidentification syndromes are characterized by a belief in duplicates and replacements. They can be classified as forms of reduplication expressed in the modalities of person, place, time and event, objects, parts of the body and the self. Common features are selectivity, coexistence of forms, intact recognition and faulty identification, depersonalization, and symbolic representation of the patient’s feelings, experiences and problems. A neural substrate of altered connectivity of multimodal cortical association areas and paralimbic and limbic structures resulting in a cognitive-perceptual-affective dissonance is suggested.

摘要:

The term ‘delusional misidentification syndromes’ (DMS) encompasses disparate clinical phenomena. This lack of agreement has resulted in a proliferation of definitions and classifications and impeded progress in aetiological research. It is suggested here that one reason for such confusion lies in current overemphasis on the content of such phenomena and a consequent neglect of their form. Research directed at clarifying the protean forms in which misidentifications manifest themselves should help to delineate more stable clinical phenomena and identify causal mechanisms.

摘要:

A case study of a schizophrenic patient with differing forms of experiences of inappropriate familiarity is described. Reduplicative paramnesia is redefined as a delusion of familiarity related to a reduplication of time, place or person. The author proposes the concept of a continuum of positive and negative misidentifïcation symptoms. The positive pole of the continuum ranges from the minor form of déjà vu experience to reduplicative paramnesia. The negative pole ranges from depersonalisation to nihilistic delusions. Differentiation is based on the severity of the disturbance of reality testing. The argumentation is based on the fact that both déjà vu experiences and depersonalisation occurring in pathological as well as non-pathological conditions are phenomenologically uniform.

摘要:

The prevalence of delusional misidentification syndromes (DMS) in a consecutive sample of 195 inpatient admissions with functional psychosis was found to be 4.1%. It is argued that DMS symptoms are more common than previously supposed.

摘要:

Delusional misidentification syndromes (DMS) are beginning to be well described clinically but little is known about their epidemiology. To try and obtain an estimate of their prevalence, a survey was performed of all admissions to a locked psychiatric inpatient unit from April 1983 to June 1984. 26 patients satisfied clinical criteria for DMS during this time and overall 835 patients were admitted to the unit. Thus, a crude prevalence of 3.1% was found. The median age of the patients was 29 years. The overwhelming majority had a principal psychiatric diagnosis of paranoid schizophrenia and only 2 of an affective disorder. By a small margin, most patients were male. The implications and limitations of these findings are discussed.

摘要:

Over the last eight decades a plethora of psychodynamic explanations have been invoked to account for the Capgras delusion. While often ill-founded and convoluted, these formulations have, until recently, dominated many theoretical approaches to the phenomenon. Generally post hoc and ideological in nature, they postulate motives that are not intro-spectable and defence mechanisms that cannot be observed, measured or refuted. While psychosocial factors can and often do play a part in the development, content and course of the Capgras delusion in individual patients it remains to be proven that such factors are necessary and sufficient to account for delusional misidentification in general and the Capgras delusion in particular.
