[Evoked parietal spikes in the electroencephalogram and febrile convulsions].

Abstract:

:In a population of 2307 children, 69 (2.99%) showed in the EEG high-voltage evoked potentials (evoked spikes) elicited by tapping on the feet or hands. Febrile convulsions were mentioned in 226 cases, and 13 of them showed the evoked spikes in the EEG and were otherwise neurologically and psychologically normal. Association between febrile convulsions and evoked spikes was observed, mainly when EEG showed also epileptiform activity of parietal localization. These EEG features are probably of functional rather than organic nature, and with possible genetic mechanisms involved. Longitudinal studies of children with febrile convulsions and evoked spikes in the EEG are necessary to verify a possible high risk of developing epilepsy not predicted on clinical data.
