“…Capgras syndrome consists of a delusion in which the affected person believes that others exhibit radical changes in psychological identity with no changes in physical appearance [7][8][9][10][11], Fregoli syndrome consists of a delusion in which the affected person believes that another experiences radical changes in physical ap pearance without change in psychological identity [10,12] . The central delusion associated with the syndrome of intermetamorphosis is the belief that others have experienced radical changes in both their physical and psychological identities [1,2,10].…”

Approaching Delusional Misidentification Syndromes as a Disorder of the Sense of Uniqueness

Co-occurrence of the different types of delusional misidentification syndromes (DMS) implies a common pathogenetic substrate. Until now, theoretical explanations have strained to produce a collective approach, but have been trammeled by the initial definition of the syndromes (Capgras/Fregoli) that originated from the attribution of causal significance to the element of familiarity towards the misidentified object. In this article, we present two cases illustrating the co-occurrence of the syndromes and we attempt to propose a new approach to DMS. We hypothesize that a common potential pathogenetic factor underlying DMS could be a disorder of the sense of uniqueness. The ability to attribute uniqueness to the self and to surrounding people, objects, or places is a principal property of the adaptable mind that acts as a matrix for the identification process. We propose that although the term ‘identity’ encompasses the concept of uniqueness, this must be accomplished somewhere in a model of semantic processing of identity. Our approach is questioning the current view that this sequential stage is the PIN stage in the functional model of face recognition by Bruce and Young, and we attempt to see the disordered sense of uniqueness within the evolved form of the model of face recognition and delusional misidentification introduced by Ellis and Lewis. We propose that such a disturbance could result in an unstable identification process, vulnerable to discrepancies in perceptual, emotional, or memory input caused by psychotic or organic mental states, thus resulting in a breakdown of the identification process that inevitably leads to a delusion of denial of identity, or to a delusion of ‘doubles’.

“…Most cases occur in patients suffering from a paranoid psychosis but four cases have been described in English language literature (6,8,9) in which the symptom was part of an affective psychosis, in one instance occurring in both the manic and depressed phases of a manic-depressive illness (8). However, even in these affective psychoses, a strong paranoid feature was noted.…”

“…This syndrome of non-recognition or delusional misidentification is usually associated with a paranoid psychosis, although it has been reported in cases of affective psychosis (6,8,9). Invariably, the phenomenon dominates the symptomatology of the illness and greatly influences the behaviour of the patient.…”

Capgras' Syndrome: the Illusion of Doubles

Bankier

1966

Canadian Psychiatric Association Journal

View full text Add to dashboard Cite

The Capgras illusion is a rare symptom occurring in patients suffering from a psychotic illness having strong paranoid features. The patient misidentifies a close relative and believes instead that a double of the relative has been created. A brief review of the literature is given, followed by a detailed account of one unusual case recently observed by the author. The various theories concerning the ætiology of the symptom are discussed.
