Abstract

EEGs and behavioral responses were studied in two sex matched groups of 58 epileptic and 20 healthy children between 8 and 12 years of age, during the execution of a go-no go CPT (X; A-X) task to determine transitory cognitive impairment (TCI) incidence. Paroxysmal discharges were found on 87.9% and 5% of the EEGs in the epileptic and control groups respectively, with no differences related to sex. The predominant EEG findings with respect to paroxysmal discharges were the association of two or more types of paroxysms with frequency higher than 5/minute, an average duration less than 0.5 second and topographical distribution over temporal-parietal-occipital areas without significant interhemispheric differences. TCI was detected in 36.2% of epileptic children. The epileptic group showed significantly higher numbers of behavioral errors and longer reaction times (RTs) in relation to the control group. Analyzing RTs on the two blocks of the task, linear discriminant analysis showed an acceptable classification of TCI incidence between groups.

癫痫儿童在CPT任务中的短暂性认知障碍。

研究了58名8 - 12岁的癫痫儿童和20名8 - 12岁的健康儿童在执行go-no - go CPT期间的脑电图和行为反应。A-X)任务来确定短暂性认知障碍(TCI)的发生率。癫痫组发作性放电发生率为87.9%，对照组为5%，无性别差异。发作性放电的主要脑电图表现为两种或两种以上的发作相关联，发作频率高于5次/分钟，平均持续时间小于0.5秒，在颞-顶叶-枕区的地形分布无显著的半球间差异。36.2%的癫痫患儿检出TCI。与对照组相比，癫痫组表现出更多的行为错误和更长的反应时间(RTs)。通过对两组任务的RTs分析，线性判别分析显示组间TCI发生率的分类是可接受的。
