[EEG in offspring of epileptic mothers].

In a group of 134 children of epileptic mothers abnormal EEG tracings were found in 39.6% of cases, 7 of these children (5.2%) had epileptic seizures. In 92% of cases EEG changes had the character of paroxysmal dysrythmia, and they were significantly more frequent in children aged 5 to 14 years and significantly more frequent in the children of mothers who had had epilepsy before the age of 20 years. Pathological EEG changes were more frequent in daughters than in sons, and in the daughters generalized discharges of centrencephalic type were significantly more frequent. In all families with more than two children at least one child had pathological EEG tracings.
