“…However, exactly this presentation was reported in Capgras and Reboul-Lachaux’s ( 1994 ) original case study where Madame M. believed her family had been replaced by impostors but also believed residents of Paris and the “whole world” had been replaced. It has also been reported as a minority presentation of Capgras delusion in the literature since (see reviews in Berson, 1983 ; Pandis et al ., 2019 ) although the extent to which Capgras delusion solely presents as non-familiar person misidentification, or is accompanied by non-familiar person misidentification, has been difficult to assess systematically.…”

Introduction:Although important to cognitive neuropsychiatry and theories of delusions, Capgras delusion has largely been reported in single case studies. Bell et al. [2017. Uncovering Capgras delusion using a large scale medical records database. British Journal of Psychiatry Open, 3(4), 179–185] previously deployed computational and clinical case identification on a large-scale medical records database to report a case series of 84 individuals with Capgras delusion. We replicated this approach on a new database from a different mental health service provider while additionally examining instances of violence, given previous claims that Capgras is a forensic risk.Methods:We identified 34 additional cases of Capgras. Delusion phenomenology, clinical characteristics, and presence of lesions detected by neuroimaging were extracted.Results:Although most cases involved misidentification of family members or partners, a notable minority (20.6%) included the misidentification of others. Capgras typically did not present as a monothematic delusion. Few cases had identifiable lesions with no evidence of right-hemisphere bias. There was no evidence of physical violence associated with Capgras.Conclusions:Findings closely replicate Bell et al. (2017). The majority of Capgras delusion phenomenology conforms to the “dual route” model although a significant minority of cases cannot be explained by this framework.

“…The Capgras delusion has usually been recognized in the contextual relationship of psychiatric disorders and often occurs in conjunction with paranoia, derealization, and depersonalization [6]. The Capgras syndrome may represent a delusional evolution of the phenomena of depersonalization and derealization [25]. Nonspecific, derealization-depersonalization experiences are frequent, especially in psychotic disorders, and are considered a significant core symptom of CS [7].…”

Capgras delusion is a complex psychopathological phenomenon that presents in a wide range of psychiatric and neurological disorders with differing patterns dependent on the main etiology. An underlying neurological disease should be suspected where the delusion concerns a spouse or inanimate objects and is associated with visual hallucinations, while a functional disorder is suggested by multiple imposters, strangers, additional delusions, and auditory hallucinations. Misidentifications in Capgras syndrome (CS) are fixed false beliefs and, therefore, represent true delusions. Even if when patients are confronted over and over with the illogical nature of the delusion, they keep their beliefs. Surprisingly, patients may show implicit or explicit awareness of their true situation. Some research suggests that a considerable number of patients with CS have some awareness of the bizarre nature of the misidentification delusions and therefore tend not to report them, especially during initial interviews when they are less likely to be confident with the clinician. Specific questions and interventions may assist clinicians in successfully identifying patients with CS. In a series of interviews with these patients, some focus on identifying CS, rather than a single interview which is likely to increase the detection of the delusional misidentification. The clinician should always be mindful of the risk of aggression and homicide in CS.

“…Neben frühen psychodynamischen ätiologischen Modellen (z. B. Ablehnung oder inzestuöses Begehren von Familienangehörigen [19]), verweist bereits Capgras eigener Erklärungsversuch des von ihm beschriebenen Wahns, es komme dabei zu einem "Verlust der affektiven Vertrautheit für Gesichter während der initialen Gesichtserkennung" [1] auf spätere neuropsychologische Erklärungsmodelle [11,[20][21][22]. Seit den Arbeiten von Ellis [23,24] wird angenommen, dass ein Missverhältnis von kognitivem und affektivem Erkennen von Gesichtern besteht.…”

“…Während manche Autoren bereits seit den späten 1980er-Jahren über ein erhöhtes Risiko von Gewalttätigkeit bei WM berichten [2,3,25,26], betonen neuere Arbeiten hierbei einen möglichen Bias durch Einzelfallpublikationen [21,27]. So findet Pandis in seiner aktuellen systematischen Nachuntersuchung von 255 publizierten Fällen mit Capgras-Wahn bei gut einem Drittel der Patienten fremdaggressives Verhalten (bei 4 % sogar mit Tötungsdelikten) und interpretiert dies entweder als möglichen Hinweis für die Gefährlichkeit von WM oder als Ausdruck eines Publikations-Bias [19].…”

Zusammenfassung Einleitung und Methode Anhand von 3 Kasuistiken werden der Zusammenhang zwischen Wahnhafter Missidentifikation (WM) und fremdaggressivem Verhalten dargestellt und sowohl präventive Maßnahmen als auch die Handhabung dadurch bedingter gewalttätiger Übergriffe diskutiert. Ergebnisse und Schlussfolgerung WM kann eine Ursache für fremdaggressives Verhalten von Patienten mit psychischen Erkrankungen sein und sowohl zu Gewalttätigkeit gegenüber nahen Bezugspersonen als auch gegenüber nicht vertrauten Menschen, wie z. B. Mitarbeitern psychiatrischer Einrichtungen, führen. Als eigenständiger Risikofaktor für fremdaggressives Verhalten sollte WM sowohl bei der stationär-psychiatrischen Aufnahme eines Patienten als auch im weiteren Verlauf exploriert werden. Außerdem könnte bei Patienten mit WM erwogen werden, mittels strukturierter Fragebögen weitere Risikofaktoren für aggressives Verhalten zu erfassen und ggf. präventive Sicherheitsmaßnahmen (z. B. Behandlung im Wachbereich, Medikation) durchzuführen.
