A case of Fregoli syndrome in schizophrenia

Syndromes of delusional misidentification and reduplication are among the many neuropsychiatric conditions that affect both brain and behaviour and pose great challenges to mental health professionals. Fregoli syndrome belongs to the group of delusional misidentification syndromes with the belief that a familiar person is disguised as a strange person by taking different physical appearance but remains the same person psychologically. Though this he syndrome has been associated with organic cerebral dysfunction particularly of the right hemisphere, most cases occur in the setting of schizophrenia. Here we report a schizophrenic patient who developed Frégoli syndrome.
