新诊断原发性或隐源性癫痫儿童注意功能的研究

摘要

Objective To study the character of attention in schoolchildren with newly diagnosed idiopathic or cryptogenic epilepsy . Methods A battery of tasks comprised Stroop Word-Color task, Trail making (A and B)and Letter cancellation task. Results There were significant differences in reaction time of color test and in inaccuracy of word test and color -word interference test. But children with epilepsy could not be distinguished from controls in Stroop interference effects ,Trail making and Letter cancellation task. Linear Regression estimated the coefficients of the linear equation ,involving age,gender,education level,duration,age at onset of epilepsy and seizure frequency, and age was the main factor that best predicted the value of the reaction time of word -color test. Conclusions Children with idiopathic or cryptogenic epilepsy have selective attention deficits . And the risk of attention deficits is higher when the patient is younger .%目的 研究原发性或隐源性癫痫儿童注意功能的特点.方法 采用Stroop字色干扰测试、连线测试A、B以及数字划消测试对新诊断原发性或隐源性癫痫儿童注意功能进行评定.结果 新诊断原发性或隐源性癫痫儿童组与正常儿童比较,Stroop测试的读色时间,读字和读字色的错误率存在显著性差异(P<0.05),而Stroop效应无显著性差异(P>0.05).两组儿童连线测试的反应时间、错误步数以及数字划消测试的划消效率无显著性差异(P>0.05).多元线性回归分析发现,在年龄、性别、受教育程度、病程、起病年龄和发作频率等多个变量中,年龄是影响读字色测试反应时间最主要的因素.结论 原发性或隐源性癫痫儿童具有选择性注意损害.年龄越小的患者选择注意受损的可能性大.
