Anti-NMDA Receptor Encephalitis Which Has Shown Clinical Symptoms of Schizophrenia

ABSTRACT

Encephalitis associated with antibodies to the N-methyl-D-aspartate (NMDA) receptor has variable clinical manifestations and treatment responses. Anti-NMDAR encephalitis is often associated with ovarian teratoma, but some cases without tumor have been reported. Here, we describe a patient who has shown psychiatric symptoms, memory impairment and been diagnosed as schizophrenia for one year and had anti-NMDA receptor antibody. The patient showed atypical clinical course compared to previous cases with anti-NMDA receptor encephalitis.
