Capgras syndrome, Fregoli syndrome, reduplicative paramnesia, and intermetamorphosis illusion are classified under the misidentification syndromes. The common characteristic of the delusional misidentification syndromes is individuals identification of people, objects or events as disguised. Among these syndromes, the most common one is the Capgras syndrome. The main feature of this syndrome is a delusional belief that the closest people around the individual, such as the spouse, mother or father, are not genuine but in fact impostors. This belief can be temporary, repetitive or persistent. In some cases places, animals or objects as well as people can be misidentified. This paper presents a case with Capgras syndrome comorbid in a patient, who is followed up with the diagnosis of paranoid schizophrenia and displays aggressive behavior against the family members. The case is presented with the consideration that it may provide contributions to the literature as it is a rarely seen disorder, which may be overlooked in the clinical practice of psychiatry.
Key words: Capgras syndrome, paranoid schizophrenia, antipsychotics, delusions
