Capgras Syndrome

Guide Note: Sufferers of Capgras Syndrome, also known as Capgras Delusion, believe that a person or people close to them have been replaced with duplicates. In some cases, the afflicted may doubt their own identity, and question whether they, in whole or in part, have been replaced with an impostor.

Although the syndrome is most common among schizophrenics, it can also occur as a result of severe brain injury or dementia, and its effects may be acute, chronic, or transient. Unlike many other delusions associated with schizophrenia, those who suffer from Capgras do not believe that the impostors are out "to get them," but neither can they explain why their loved one has been replaced.

The delusions center around one of the senses—most often sight—and remain localized to that one sense. For example, a man afflicted with Capgras may recognize his wife's voice on the phone, yet believe her to be an impostor upon seeing her in person.
