Delusional misidentification syndromes include a group of delusional disorders involving a belief that the person(s)/ object(s)/ or place(s) around the patient have changed or have been changed. Those disorders can develop on the basis of mental or neurological disorders. In this paper, a case with Capgras syndrome, intermetamorphosis and reduplicative paramnesia is presented. The patient was a fourty-three years old female and her complaints had been continuing for five years. She displayed reduplicative paramnesia, intermetamorphosis and Capgras syndrome in her history. Her mental status examination scores was 100 for Positive and Negative Symptoms Scale (PANSS, positive signs: 26, negative signs: 20, general psychopathology: 54) and 23 for Mini Mental Test. No pathology could be found in Bender Gestalt test. Because her physical and neurological examinations, as well as laboratory results and imaging findings were unremarkable, she was thought to fulfill the diagnosis criteria for Schizophrenia-Paranoid Type (Continuous Course) and she was given 10 sessions of electroconvulsive therapy. The patient was presented in this case report because she had a comorbidity consisting of Capgras syndrome, reduplicative paramnesia and intermetamorphosis and she responded favorably to electroconvulsive treatment.
