The reactivity of rolandic spikes (RS) and the occurrence of transitory cognitive impairment (TCI) during RSs were assessed in 33 children with benign childhood epilepsy with centrotemporal spikes (BECTS). The children were assessed simultaneously with EEG and computerized neuropsychological testing in a visual discrimination between words and pseudowords task (DWPT). In 20 (60.6%) children, there were insufficient RS to assess the occurrence of TCI. Of 13 children with RS between stimulus presentation and response, only 2 (15.4%) made a significantly greater proportion of errors during RS than during RS-free periods, characterizing the occurrence of TCI. The RS appear to be easily inhibited by the DWPT. TCI occurred in a limited number of cases and did not impair school performance. There is a need to study other tasks and search for other factors influencing cognitive abilities in children with BECTS.
在33例伴有中央颞区棘波的儿童良性癫痫（BECTS）患儿中，评估了中央颞区棘波（RS）的反应性以及RS期间短暂性认知障碍（TCI）的发生情况。在一项单词与假词视觉辨别任务（DWPT）中，同时通过脑电图（EEG）和计算机化神经心理学测试对这些患儿进行评估。20例（60.6%）患儿的RS不足，无法评估TCI的发生情况。在13例刺激呈现与反应之间出现RS的患儿中，只有2例（15.4%）在RS期间出现的错误比例明显高于无RS期间，这表明出现了TCI。RS似乎很容易被DWPT抑制。TCI仅在少数病例中出现，且未影响学业成绩。有必要研究其他任务，并寻找影响BECTS患儿认知能力的其他因素。
