Cotard's syndrome in psychogeriatric patients in Hong Kong

Cotard's syndrome is characterized by the presence of nihilistic delusions. A retrospective case note study of 349 Chinese psychogeriatric patients in Hong Kong showed a prevalence of 0.57% of the syndrome. The two patients identified were both females with major depression. Case vignettes of these patients were presented and the similarity of the clinical features to those described in the Western literature was discussed.
