Capgras Syndrome is a delusional misidentification syndrome that is characterized by a false belief that an identical duplicate has replaced someone significant to the person.

There's currently no cure for Capgras syndrome, and even treatment can be challenging.

If a person with Capgras Syndrome has another mental disorder that has been linked to the condition, treating that mental disorder can sometimes ease symptoms of Capgras syndrome.

Joseph Capgras first described this delusion and Capgras syndrome in 1923, and called it “l'illusion des sosies”.

Capgras and Reboul-Lachaux described the case of a woman who, among other psychotic symptoms, developed the delusional belief that her husband, children, neighbors, and others had been replaced by doubles.

People with Capgras syndrome experience the belief that an imposter has replaced someone they know or recognize.

It can be caused by brain injury, structural changes in the brain, or other conditions such as schizophrenia.

Treating the cause of Crapgras syndrome may help improve the symptoms.

The prevalence of Capgras syndrome among the general population is 0.12%, while in the psychiatric population rises to 1.3%.

The etiology of Capgras syndrome can be variable, being in most of the cases associated with preexistence neuropsychiatric conditions.
