Background: Delusional misindentification syndromes are divided into Capgras syndrome, Fregoli syndrome, subjective double syndrome and intermetamorphosis syndrome. The main feature is a failure to identify itself and/or others. These phenomena are relatively rare, etiologically heterogeneous and occur mainly in the setting of schizophrenic disorder, affective disorders and organic diseases.
Aims: Present a case report of a patient with three delusional misindentification syndromes and review the etiology and psychopathology of these conditions.
Methods: Clinical case and a non-systematic review in English through research in PubMed was conducted with the expressions: “delusional misidentification syndromes”, “Capgras Syndrome”, “Fregoli Syndrome”, “Double Subjective Syndrome”. A literature review of the theme was shortly performed.
Results and Conclusions: We reporte a case of a man with paranoid schizophrenia with three delusional misidentification syndromes associated (Capgras syndrome, Fregoli syndrome and subjective double syndrome). It seems that they are underdiagnosed phenomena and their active research may allow a more complete understanding of the clinical conditions in which
they arise.
