[Study on focalized EEG paroxysms in children (author's transl)].

The authors studied 111 children whose EEG showed paroxysmal foci on the lateral areas of the skull, often on the rolandic and temporal areas, but also on occipital, parietal and frontal areas. In 60% of the cases there was no clinical epileptic manifestation. In 25% of the cases those foci were responsible for epileptic seizures with good prognosis; in 15% of the cases they were associated with other epileptogenic processes responsible for epileptic fits of unfavorable evolution. The past history of these children had been studied in particular: hyperthermic convulsions and lateralisation difficulties were very frequent, but organic lesions were also found, which, although they did not seem to be directly responsible for the foci, were related to the organic lesion by a reactional or 'functional' factor.
