Answer: E. Fregoli syndrome describes where a familiar person (his wife) is falsely identified in strangers. This is in contrast to Capgras’ syndrome (where the familiar person is supplanted by a stranger who is their exact double). Sosia illusion describes where, along with the spouse in Capgras, other people have been replaced with doubles. Intermetamorphosis is where the exchange of individuals is reciprocal, with the process involving physical and psychological character istics. Subjective doubles involve the double of oneself, i.e. a person believes that another individual has been transformed into his own self. [F. p. 85]

Delusional misidentification in Parkinson’s disease: report of two cases and a review
Published in Postgraduate Medicine, 2018
The following misidentification syndromes have been described in association with PD. All of these syndromes were initially reported in patients with diseases other than PD. Capgras syndrome. The most common DMS, a person with Capgras syndrome believes a familiar person, often a spouse, has been replaced by an impostor, a substitute who physically appears to be the familiar person, but is not that person. This delusion of reduced familiarity has also been observed in the perception of places, animals, and objects [16,17]. To date, Capgras syndrome has been reported in a total of 30 patients with PD [14,18–20].Fregoli syndrome. This consists of the delusion that a familiar person, usually someone malevolent, appears disguised as another person, or other people. To my knowledge, only one case of Fregoli syndrome has been reported in a patient with PD [21].Intermetamorphosis. This delusion has been regarded as a combination of both the Capgras and Fregoli syndromes, in that a familiar person is thought to take both the physical appearance and the psychology of another person or other people. Rarely reported in PD, two cases of intermetamorphosis in patients with PD dementia have been formally characterized as such in the medical literature [15]. One subject intermittently mistook her daughter for her mother, and another persistently believed his wife to be his sister.Reduplicative syndromes. This is the delusion that a person, place, or event has been duplicated perhaps in several copies, and coexists with the original. When the duplication is of a place that coexists in a different location this is referred to as reduplicative paramnesia [22]. Reports of reduplicative paramnesia and reduplication of a person are uncommon in PD, but two cases of the former and one of the latter were identified in the above referenced DMS prospective study [15].
