Para-infectious encephalopathies in childhood. EEG-aspects and familial occurrence

The authors report on infectious-allergic encephalopathy, occurring in a nine-year old boy. The clinical picture is that of a generalized myoclonic epileptic state. The EEG shows bilaterally occurring stereotyped rhythmic complexes with a short interval. The child recovered completely. The diagnostic value of periodically occurring EEG-features and the familial occurrence of para-infectious encephalopathies are discussed.
