A Clinical Study on Japanese Encephalitis with Psychiatric Manifestations

ABSTRACT

Twenty-one patients of the adult Japanese encephalitis, who had been admitted in National Medical Center during recent two years, were investigated to evaluate their epidemiological features and clinical courses. Male patients were more frequently affected than female, and forty-three percepts of patients were third decade. The peripheral leukocytosis and mild pleocytosis and non specific inflammatory findings in cerebrospinal fluid were observed, all case had positive titer in hemoagglutination inhibition test. The incidence of neuropsychiatric sequelas of Japanese encephaltis was about 67%, and among them speech disturbance was most frequent. Further epidemiological and microbiological studies should be necessary to evaluate the tendency of recent increment in incidence of adult type of Japanese encephalitis.
