“…His neuropsychological profile is consistent with brain-imaging data: (i) dysexecutive and apatheticakinetic syndromes usually reflect bilateral frontal damage; (ii) retrograde episodic amnesia (Kopelman, 2002) presumably reflects the focal right temporal lesion (Markowitsch, 2003). These neuro-imaging findings are consistent with those described in other cases of misidentification syndrome, which showed bilateral frontal and right temporo-parietal hemisphere damage (Doran, 1990;Luzzatti & Verga, 1996;Devinsky, 2009). …”

“…The DMS are considered pathological conditions of decreased (or increased) familiarity (Devinsky, 2009). Several neurological patients with delusions described in the literature presented bilateral frontal and right temporo-parietal lesions (Devinsky, 2009;Doran, 1990;Luzzatti & Verga, 1996). It has been suggested that right temporal lesions impair familiarity processing, causing familiar people, places, and body parts to appear foreign, and that the bilateral frontal dysfunction impairs the ability to monitor the appropriateness of the sense of familiarity emerging from the familiarity processing.…”

This paper reports the case of a patient, M.P., who developed delusion of inanimate doubles, without Capgras syndrome, after traumatic brain injury. His delusional symptoms were studied longitudinally and the cognitive impairments associated with delusion were investigated. Data suggest that M.P. did 'perceive' the actual differences between doubles and originals rather than 'confabulate' them. The cognitive profile, characterized by retrograde episodic amnesia, but neither object processing impairment nor confabulations, supports this hypothesis. The study examines the nature of object misidentification based on Ellis' and Staton's account and proposes a new account based on concurrent unbiased retrieval of semantic memory traces and biased recollection of episodic memory traces.

“…In more recent studies, the delusion has served as the focus for an etiological debate supported by investigators who believe that the disorder has organic causes (Christodoulou, 1977;Collins et al, 1990;F6rstl, 1990;Joseph, 1986aJoseph, , 1986bJoseph et al, 1990;Luaut6 et al, 1990;Spier, 1992) and by investigators who are convinced that it is caused by psychodynamic factors (Berson, 1983;Christodoulou, 1977;Enoch and Trethowan, 1991;Koritar and Steiner, 1988;O'Reilly and Malhotra, 1987;Shraberg and Weitzel, 1979;Sinkman, 1983;Spier, 1992). McAllister (1992), Critchley (1989), Cutting (1991), Doran (1990), F6rstl (1990), and Koritar and Steiner (1988) have suggested that Capgras delusion stems from a coalescence of organic and psychodynamic factors. Signer (1992) reported that one-third of 488 cases of this so-called rare disorder and its variants showed a neurologic tendency.…”

Can we learn from the clinically significant face processing deficits, prosopagnosia and capgras delusion?

This review describes two clinically significant face processing deficits, prosopagnosia and Capgras delusion, and provides new knowledge about the face recognition process by a convergence of empirical findings. These empirical findings are structured around two questions that are reviewed from the perspectives of the two deficits. First is the question of hemispheric specificity, which inquires into the degree of each hemisphere's contribution to the face recognition process. Second is the question of dual neural pathways, which addresses the possibility that the face recognition process proceeds along two parallel pathways in the brain. Findings from the hemispheric specificity studies reinforce the current view that right hemispheric involvement is necessary for face recognition while left hemispheric involvement is minimal. Findings from the dual neural pathways studies reinforce the plausible but yet unproven hypothesis that two neural pathways pass information from the visual association cortex in the occipital lobe toward the temporal lobes and limbic system when faces are seen and recognized. These findings, which also indicate that each of the dual neural pathways carries different, nonredundant information, could be instrumental in showing that the pathways play different roles in the manifestations of the clinically significant face processing deficits, prosopagnosia and Capgras delusion.

“…The original Ellis and Young hypothesis included all sense modalities , but the fact they specifically used the visual processing of the face to argue their case appears to have led to a split in the literature. Some researchers predominately define the Capgras delusion as being specific to people (Bourget & Whitehurst: 2004;Brighetti et al 2007;Coltheart: 2007;Dietl, Brunner & Friess: 2003;Doran: 1990;Josephs: 2007;Tamam et al: 2003;Young, G. : 2008), whilst others extend the syndrome to include inanimate objects such as household furniture (Ellis et al: 1996;Nejad & Toofani: 2006) and animals, particularly pets ( Ellis et al: 1996;Rosler et al: 2001).…”
