title: Capgras syndrome in siblings.
abstract: The hallmark of the Capgras Syndrome is delusional misidentification of persons, objects or animals. It can occur in organic syndromes and in functional disorders. Hence there are adherents of organic as well as dynamic factors in the genesis of this disorder. The authors report the occurrence of the Capgras Syndrome in a brother and sister and elaborate on the interplay of both genetic and dynamic factors in the etiology.
