[Acute necrotic encephalitis in children (clinico-electroencephalographic study)].

Twenty-five children aged 3 months to 13 years were examined electro-encephalographically. Most of the patients (20 of the 25) were young children (under 3 years of age) with the diagnosis of acute necrotic encephalitis. The characteristic changes of the EEG expressed in the form of cyclically arising asymmetric giant slow waves were established. The nature of the EEG was shown to correlate with the gravity of the clinical course. The data obtained may be used both diagnostically and prognostically.
