An Analysis of Routine-EEG-Findings with a View to Surgical Treatment of Epilepsy
EEG-investigations of epileptic patients in our laboratory usual over ten years have shown that about 50% have typical temporallobe-epilepsy and form the greatest group in the so-called symptomatic epilepsy. Most of them (about 2/3) had general pathological bioelectric activity. One or more foci with different functional correlation were found in 70% of our cases. Typical epileptic activity with spikes, spike-waves or high-amplitude sharp-waves was recorded very rarely on the scalp, particularly during the intervall. The most common localisation of epileptic foci was in the sensomotoric area and in the temporal lobe. Sometimes two or more foci occurred with corresponding bioelectric activity, althrough generally the foci were independent.
