The relation of Cotard's syndrome to delusional misidentification

A case of Cotard's syndrome with face processing deficits is described. The phenomenology of Cotard's syndrome may be an expression of underlying visual processing deficits, including abnormalities in face perception processing. Phenomenologic and neurobiologic characteristics of this case are similar to those found among delusional misidentification syndromes. This similarity suggests areas for further study that may lead to a better understanding of the relation of phenomenology to neurobiology in Cotard's syndrome.
