title: [EEG analysis and prognosis in 125 cases of non-hyperpyretic seizures occurring in children under three (author's transl)].
abstract: Between 1955 and 1970 recordings were made from 125 children aged 1-36 months who had had a first epileptic seizure (non-hyperthermic). 100 of these children were followed up for from 5 to 20 years: 35 had had their first seizure before 1 year of age and 65 between the age of 1 and 3. Hypsarrythmia was more frequent under 1 year of age, whereas short diffuse spike and wave bursts were observed only after 1 year. However, localized spikes, asymmetrical or slow tracings as well as normal tracings were observed in both groups, without significant difference. A fatal outcome is more frequent when the first seizure took place before the age of 1 year. However, in our sample the intellectual development of the surviving children does not depend on the time of the first seizure. In any case the prognosis is unfavorable, since only 31 of the children followed up developed normally.
