Analysis of scalp electroencephalogram (EEG) findings is indispensable to investigation of epilepsy surgery candidates. Maxima of slowing and epileptiform spiking on interictal EEG reflect gross localization of core epileptogenic regions within a network. Important negative scalp EEG findings are those associated with deep foci. Ictal EEG is important in confirming concordance with interictal EEG and other ancillary data. Generalized interictal and ictal EEG findings may occur in epilepsies that are otherwise focal. Detailed individual analyses of scalp EEG features are prelude to a more global synthesis, whose coherence in suggesting plausible network hypothesis presage a subsequently successful scalp EEG evaluation.
分析头皮脑电图(EEG)发现对于癫痫手术候选者的研究是不可或缺的。发作间期 EEG 上的慢波和癫痫样尖波的最大值反映了核心致痫区域在网络内的大体定位。重要的负性头皮 EEG 发现与深部病灶有关。发作期 EEG 对于确认与发作间期 EEG 和其他辅助数据的一致性非常重要。在其他方面为局灶性的癫痫中,可能会出现发作间期和发作期的全身性 EEG 发现。头皮 EEG 特征的详细个体分析是更全面综合的前奏,其在提出合理的网络假说方面的一致性预示着随后成功的头皮 EEG 评估。
