SEPs were performed in 44 children with benign partial epilepsy with rolandic spikes (BERS). High-amplitude mid- or long-latency SEPs were recorded in 17 patients (38%). These giant responses showed normal latency values but reached an exceedingly high amplitude (up to 200 microV). They showed the same reactivity characteristic of normal long-latency SEPs. In a 3-year follow-up study, the giant responses were shown to disappear in some patients and to shift from side to side in others. Our study demonstrates that giant SEPs are relatively common in BERS and give further support to the concept of a functional nature of rolandic foci.
对44例伴中央颞区棘波的儿童良性部分性癫痫（BERS）患者进行了体感诱发电位（SEP）检查。17例患者（38%）记录到高波幅的中或长潜伏期SEP。这些巨大反应潜伏期值正常，但波幅极高（可达200微伏）。它们表现出与正常长潜伏期SEP相同的反应特性。在一项为期3年的随访研究中，一些患者的巨大反应消失，另一些患者的巨大反应则在两侧之间转换。我们的研究表明，巨大SEP在BERS中相对常见，进一步支持了中央颞区病灶具有功能性的概念。
