Capgras Delusion is a psychological condition where a person believes that someone they know, often a family member or close friend, has been replaced by an identical impostor. This delusion can occur in various mental health disorders, including schizophrenia and dementia. The individual may express strong emotions about the perceived impostor, leading to confusion and distress. The exact cause of Capgras Delusion is not fully understood, but it is thought to involve a disconnect between facial recognition and emotional response. This disconnect may result from brain injuries or neurological conditions affecting areas responsible for processing familiar faces, such as the fusiform gyrus.
