[Clinical variants of epidemic encephalitis in Primor'e].

The authors examined 104 patients with epidemic encephalitis (48 in the acute stage and 56 in chronic). In the acute stage the following forms were distinguished: vestibular, lethargic, hyperkinetic and psychosensory. The chronic stage included postencephalitic parkinsonism, hyperkinetic and lethargic forms. The acute stage had a mild development without lethal outcomes. The specific traits of epidemic encephalitis in this region were the frequency of vestibular forms in the acute stage and hyperkinetic forms in the chronic one.
