Accounts of the major DMSs are given using theoretical models of the functional components underlying recognition of familiar people. Thus, Capgras' syndrome is suggested to involve impairment of processes that can support ‘covert’ recognition of familiar faces in prosopagnosia. It therefore forms a potential ‘mirror image’ of the impairments underlying prosopagnosia, and earlier attempts to link the two conditions directly are questioned. Frégoli syndrome and intermetamorphosis are explained… 
Facial processing and the delusional misidentification syndromes
Research indicates that the delusional misidentification syndromes (DMS) are linked to right hemisphere dysfunction. However, the extent and nature of any underlying processing impairment in patients
Delusion of inanimate doubles: Description of a case of focal retrograde amnesia
TLDR
Data suggest that M.P. did ‘perceive’ the actual differences between doubles and originals rather than ‘confabulate’ them, and the cognitive profile, characterized by retrograde episodic amnesia, but neither object processing impairment nor confabulations, supports this hypothesis.
Towards an Understanding of Delusions of Misidentification: Four Case Studies
Four detailed cases of delusions of misidentification (DM) are presented: two cases of misidentification of the reflected self, one of reverse intermetamorphosis, and one of reduplicative paramnesia.
Delusional misidentification of inanimate objects: a literature review and neuropsychological analysis of cognitive deficits in two cases.
TLDR
It is proposed that an extension of Ellis and Young's (1990) account of Capgras delusion can explain the cognitive impairments in case of DID.

We provide a battery of examples of delusions against which theoretical accounts can be tested. Then we identify neuropsychological anomalies that could produce the unusual experiences that may lead,

The Defensive Function of Persecutory Delusions
TLDR
Depressed and normal subjects showed similar causal inferences for both attributional measures, but deluded subjects showed a marked shift in internality, attributing negative outcomes to external causes on the transparent Attributional Style Questionnaire but, on the more opaque Pragmatic Inference Task, showing a cognitive style resembling that of the depressed group.

Delusions, dreams, and the nature of identification
Delusional misidentification is commonly understood as the product of an inference on the basis of evidence present in the subject's experience. For example, in the Capgras delusion, the patient sees

Face Recognition Dysfunction and Delusional Misidentification Syndromes (DMS)
TLDR
Capgras’ syndrome is a typical case of dysfunction of face recognition following brain damage, with the postulation of imaginery differences and the further expressed belief that the real person has been replaced by a double.
The Delusion of Inanimate Doubles
TLDR
Evidence that the Capgras delusion has long been held to be specific for close personal relationships is presented and the implications for accepting psychodynamic explanations of the phenomenon are discussed.

TLDR
Critical analysis of postmortem and CT scan data indicates that prosopagnosia is associated with bilateral lesions of the central visual system and those lesions are functionally symmetric.

Prosopagnosia is usually characterised by a sudden loss in ability to recognise faces of familiar people. Sufferers typically have then to rely on voices or dress for identifying spouse, family,

TLDR
The English and French literature on Capgras' syndrome yielded 315 patients, 212 of whom provided the basis for review, and classes of single and multiple forms of the delusion with either functional or organic etiology were compared.
