Abstract

The authors describe the frequency and characteristics of Cotard syndrome among neurological and psychiatric inpatients at a tertiary referral center. All inpatients from the National Institute of Neurology of Mexico (March 2007-May 2009) requiring neuropsychiatric consultation were reviewed. Among 1,321 inpatient consultations, 63.7% had neurological disease and one (0.11%) had viral encephalitis and Cotard syndrome. Of inpatients, 36.2% had pure psychiatric disorders and three (0.62%) had Cotard syndrome, associated with psychotic depression, depersonalization, and penile retraction (koro syndrome). This review discusses potential mechanisms for Cotard syndrome, including the role of a perceptual-emotional dissociation in self-misattribution in the deliré des negations.
