    Delusional misidentification syndrome and other unusual delusions in advanced Parkinson's disease.

    Parkinsonism Relat Disord 2013 Aug 14;19(8):751-4. Epub 2013 May 14.
    Movement Disorders Unit, Neurology Service, Hospital de Clínicas, Federal University of Paraná, Curitiba, PR, Brazil.
    Background: Unusual delusional syndromes are rare protean diseases with speculative etiopathogenic mechanisms.

    Methods: Seven consecutive patients with advanced PD were evaluated over a 15-year period at the Movement Disorders Unit in the Neurology Service, Hospital de Clínicas, Federal University of Paraná, and the Paraná State Parkinson's Patients Association.

    Results: We describe advanced Parkinson's disease patients presenting with unusual delusional syndromes, including cases of Ekbom, Othello, Capgras' and Diogenes syndromes, reduplicative paramnesia and mirrored-self misidentification.

    Conclusion: There are a few isolated reports of unusual neuropsychiatric disorders in patients with PD. We believe that these syndromes associated with advanced PD in elderly patients presenting with cognitive impairment and polypharmacy are probably often underestimated. Neurologists should be aware for these rare and treatable conditions.

    Delusional misidentification syndromes and dementia: a border zone between neurology and psychiatry.
    Am J Alzheimers Dis Other Demen 2013 Nov 27;28(7):671-8. Epub 2013 Oct 27.

    The delusional misidentification syndromes (DMSs) are psychopathologic phenomena in which a patient consistently misidentifies persons, places, objects, or events. Although often described in relation to psychotic states including schzofrenia, it is, nevertheless, widely considered that these syndromes have an anatomical basis because of their frequent association with organic brain disease; studies have pointed to the presence of identifiable lesions, especially in the right frontal lobe and adjacent regions, in a considerable proportion of patients. The purpose of this article is to examine the phenomenon in people with dementia. Read More
    The delusional misidentification syndromes in patients with and without evidence of organic cerebral disorder: a structured review of case reports.
    Biol Psychiatry 1993 Jan;33(1):22-32
    Maudsley Hospital, London, UK.
    Two series, each of 50 cases of delusional misidentification reported in the literature, were analyzed in order to study the interaction between organic and functional mental processes. The details of the time course of the development of the delusional misidentification and related mental symptoms, the phenomenology, and evidence of cognitive impairment and/or cerebral damage were recorded. The first series of cases included delusional misidentification either of place, and/or of persons; the second series was limited to cases, published since 1977, with delusional misidentification of person, who had had an electroencephalogram (EEG) and/or computerised tomographic (CT) brain scan.

    Delusional gross replacement of inanimate objects.
    Br J Psychiatry 1994 May;164(5):693-6
    Three cases of a misidentification syndrome are presented. In this syndrome, which may be Capgras' or a new syndrome that we refer to as delusional gross replacement of inanimate objects, patients believe that their new possessions are replaced by inferior copies of the original objects by identified individuals. The patients believe that these individuals want to enhance themselves at the patients' expense, and feel persecuted by them. Read More
    Psychiatric, neurological and medical aspects of misidentification syndromes: a review of 260 cases.
    Psychol Med 1991 Nov;21(4):905-10
    Section of Old Age Psychiatry, Institute of Psychiatry, London.
    Two hundred and sixty case reports of misidentification syndromes were evaluated. One hundred and seventy-four patients had a Capgras syndrome misidentifying other persons, 18 a Fregoli syndrome, 11 intermetamorphosis, 17 reduplicative paramnesia and the rest had other forms or combinations of mistaken identification. Schizophrenia (127 cases), mostly of paranoid type, affective disorder (29), and organic mental syndromes including dementia (46) were the most common diagnoses in patients who misidentified others or themselves.
