Sulpiride treatment of Cotard's syndrome in schizophrenia

A 33-year-old male suffering from schizophrenia developed the typical symptoms of Cotard's syndrome, i.e., various delusions of negation and severe depressive symptoms. Atypical symptoms such as delusions of persecution and control related to body parts were also observed. These symptoms gradually improved by the treatment with sulpiride 300 mg/day. In the course of improvement of Cotard's syndrome, the patient developed Capgras syndrome. This report suggests that sulpiride is effective for Cotard's syndrome in schizophrenia. It also suggests that the symptoms of Cotard's syndrome are modified according to basic disorders, and this syndrome has a close connection with Capgras syndrome.
