What is Capgras syndrome or the delusion?

Capgras syndrome, also called Capgras delusion, is a rare neuropsychiatric disorder in which a person believes that a close friend, family member, or other well-known person has been replaced by an imposter. The person with Capgras syndrome may believe that the impostor looks and sounds like the real person but lacks the original person's personality, memories, and emotions.

Capgras syndrome is thought to be caused by damage to the brain's right hemisphere, which is involved in facial recognition and emotional processing. It can also be caused by psychiatric illnesses, such as schizophrenia and dementia.

Capgras syndrome can be a very distressing disorder for both the person who experiences it and their loved ones. The person with Capgras syndrome may become withdrawn and suspicious, and they may refuse to interact with the people they believe to be impostors. This can lead to social isolation and relationship problems.

There is no cure for Capgras syndrome, but there are treatments that can help to manage the symptoms. These treatments may include medication, psychotherapy, and social support.
