We analyzed the effect of task dimensions (information processing demand; duration of the test; input modality) on the occurrence and cognitive impact of epileptiform EEG discharges (EEDs) or subtle epileptic seizures.
One hundred ninety-nine children, aged 6-17 years, were included consecutively in a prospective standardized study. All children were assessed with EEG, which was synchronized with a computerized cognitive FePsy test system.
No association was found between the occurrence of EEDs or subtle epileptic seizures and the three task dimensions introduced in our study. The Computerized Visual Searching Task (CVST) appeared to be particularly sensitive to direct cognitive effects of EEDs. The CVST and the three memory tests--Corsi's Block Tapping and recognition of words/figures--were sensitive to the cognitive effects of subtle epileptic seizures.
Our results do not indicate a distinctive effect of information processing demand, duration of the test, or input modality on the occurrence of EEDs or subtle epileptic seizures. Effects on the impact on cognition are found when these three factors are combined.
我们分析了任务维度（信息处理需求；测试持续时间；输入方式）对癫痫样脑电图放电（EEDs）或轻微癫痫发作的发生及其认知影响。
199 名年龄在 6-17 岁的儿童连续纳入一项前瞻性标准化研究。所有儿童均接受脑电图检查，并与计算机化认知 FePsy 测试系统同步。
EEDs 或轻微癫痫发作的发生与我们研究中引入的三个任务维度之间没有关联。计算机视觉搜索任务（CVST）似乎对 EEDs 的直接认知影响特别敏感。CVST 以及三个记忆测试——科里斯的块敲击和单词/图形识别——对轻微癫痫发作的认知影响敏感。
我们的结果表明，信息处理需求、测试持续时间或输入方式对 EEDs 或轻微癫痫发作的发生没有独特的影响。当这三个因素结合起来时，会发现对认知的影响。
