Signs and Symptoms in Psychiatry
Published in Mohamed Ahmed Abd El-Hay, Essentials of Psychiatric Assessment, 2018
Although they are a hallmark of psychotic disorders, delusions may be mani festations of neurologic disease, while reduplicative paramnesias are reported in schizophrenia and other psychotic disorders, they are seen commonly also in chronic or resolving amnestic syndromes. Sometimes reduplicative paramnesia occurs in the context of identifiable brain lesions; frontal, limbic, and right-hemispheric areas have all been implicated.

A 50-year-old man, after brain injury to the nondominant parietal lobe, came to believe that he has seen himself on a number of occasions while travelling to different cities in his country. He is aware of himself both inside and outside his body. He feels that his office has been copied and exists in two different cities. Which of the following statements is false? The knowledge of having a double is occasionally a delusion, or hallucination but more commonly is a variant of depersonalization.This condition can occur in other people without psychiatric illness.This condition consists of a delusion that a double of a person or place exists somewhere else.This condition is known as reduplicative paramnesia.This condition is a perceptual rather than ideational or cognitive disturbance.

Clinical lycanthropy is one of the delusional misidentification syndromes, which are characterised by patients misidentifying a person, place, or object, and also include Capgras syndrome, Fregoli syndrome, reduplicative paramnesia, and intermetamorphosis. Clinical lycanthropy is a syndrome in which the patient has the delusional belief of turning into a wolf. Lesions localised in the right hemisphere and frontal lobe are reported in lesion-related delusional misidentification syndromes, but wider networks may be involved. The authors report a 12-year-old pubescent adolescent born in France, who exhibited delusional ideas of wolf metamorphosis. He often heard werewolves telling him to ‘join the pack’. He often looked at himself in the mirror, believing that his eyes had changed colour and his teeth had lengthened. His mother had discovered deliberately torn trousers. The authors conducted a review on PubMed of cases of lycanthropy and cyanthropy (dog transformation) of adolescents aged younger than 20 years. They detected four patients ages 17–19. Diagnoses reported were schizophrenia, psychotic depression, and mania. It had not been previously reported as occurring during early adolescence.
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].
