Capgras syndrome is a delusional misidentification disorder where individuals believe a close person has been replaced by an imposter.
A 65-year-old male believes that an imposter has replaced his wife. He states this started 4 weeks ago and is unsure who the ‘imposter’ is and their purpose or aim. He has not been engaging with his wife and has attempted to contact the police numerous times. On discussion, he refuses to accept evidence that his wife is the same person, including information that only his wife would know. The patient has a background of schizophrenia and takes olanzapine, although his wife is unsure of how compliant he is with his medication.
