Frégoli syndrome after cerebral infarction

Abstract

A case of a rare form of delusional misidentification, the Frégoli syndrome, is described. Although usually occurring in the setting of primary or secondary schizophrenic psychoses, delusional misidentification has been reported in affective, neurological, and toxic-metabolic disorders. In this instance a diagnosis of paranoia (delusional disorder) secondary to predominantly right hemisphere pathology, rather than schizophrenia, seemed more appropriate.
