Document Summary
Capgras syndrome: rare disorder on its own, but it seems to be one of the accompaniments to alzheimer s syndrome, and so is sometimes observed among the elderly. It can also result from various injuries to the brain. Someone with capgras syndrome is fully able to recognize the people in her world (husband, parents, friends) but she is utterly convinced that these people are not who they appear to be. Real husband or son has been kidnapped, and the person standing before them is not the real article, but a well-trained imposter. In the extreme, the capgras sufferer may murder the imposter in an attempt to end the charade and find the genuine character. Facial recognition involves two separate systems in the brain, one of which leads to a cognitive appraisal and the other to a more global, somewhat emotional appraisal. Emotional processing is disrupted, leading to intellectual identifiable without the familiarity response.
