[The Capgras syndrome]

Abstract

The Capgras syndrome is one of delusional-like misidentification syndrome in which a person holds a delusion that one or several his/her friends or relatives have been replaced by an identical-looking impostor. As any other delusional disorder, the Capgras syndrome is characterized by stability despite the indisputable arguments against fault views. Initially, this syndrome was considered as a presentation of schizophrenia but later it has been described in brain organic disorders, primarily in elderly patients with dementia.
