Methods: The clinical characteristics of 9 patients with anti-NMDAR encephalitis in Department of Neurology, Army General Hospital of Chinese PLA from October 2013 to October 2015, were retrospectively analyzed. And by literatures review, the pathogenesis, clinical feature, diagnosis, treatments and prognosis of this disease were summarized.
