Capgras Syndrome is a psychological condition where a person believes that someone they know, usually a family member or close friend, has been replaced by an identical impostor.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 syndrome is thought to arise from a disconnect between facial recognition and emotional response, leading to confusion and misinterpretation of familiar faces. Individuals with Capgras Syndrome may feel a sense of fear or distrust towards the person they believe is an impostor, which can significantly impact their relationships and daily life.
