Abstract
<p>Anti-NMDA-receptor encephalitis is a relatively rare disease which often demonstrates characteristic psychiatric symptoms similar to schizophrenia. Clinical improvement can be expected when both an early diagnosis and early treatment can be achieved. We herein report a possible case of anti-NMDA-receptor encephalitis. The patient was a67-year-old man. He had been hospitalized due to the onset of acute enteritis. Eight weeks later, he started to demonstrate abnormal behavior, such as removing excrement out from his anus with his fingers and frequently going back and forth between the restroom and his bed. He also became delusional and feared that he might be beaten when he went outside, and that his wife was not his real wife. He showed various types of cognitive impairment and his MMSE score was 18/30. In a spinal fluid test, anti-glutamate receptor antibody was positive.According to these findings, anti-NMDA-receptor encephalitis was suspected and steroid treatment was thereforestarted for him. The subsequent improvement in his psychiatric symptoms and cognitive impairment was remarkable and his MMSE score improved to 25/30. Cases of anti-NMDA receptor encephalitis which develop in association with infectious diseases, including the enteritis, have been reported. As a result, when cases suddenly develop psychiatric symptoms and cognitive impairment after infection, then the possibility of anti-NMDA receptor encephalitis should therefore be included in the differential diagnosis.</p>
