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.
在2307名儿童中，69名（2.99%）在脑电图中显示出由轻拍脚部或手部诱发的高电压诱发电位（诱发棘波）。226例提及有热性惊厥，其中13例脑电图显示有诱发棘波，且在神经和心理方面其他情况正常。观察到热性惊厥与诱发棘波之间存在关联，主要是当脑电图还显示顶叶定位的癫痫样活动时。这些脑电图特征可能是功能性而非器质性的，且可能涉及遗传机制。对脑电图有热性惊厥和诱发棘波的儿童进行纵向研究，对于验证根据临床数据无法预测的癫痫发作高风险是必要的。
