[Electroencephalographic changes in patients with acute encephalitis].

EEG was used to examine 118 patients aged 17-60 with different types of acute encephalitis. In addition to EEG, clinical and laboratory methods, special (virological, serological, etc) ones were used for disease etiology specification. Necrotic (herpetic) encephalitis was diagnosed in 18 patients. EEG changes differed in their characteristics and correlated with the status gravity. Hypersynchronous slow activity was marked in the most grave patients. In acute encephalitides, EEG was considered to be a sufficiently informative differential-diagnostic and prognostic method of patients' examination.
