摘　　要：【目的】探讨儿童注意缺陷多动障碍(attention deficit hyperactivity disorder,ADHD)三个亚型儿童及正常对照组儿童脑电活动的特征。【方法】将门诊符合DSM-Ⅳ诊断标准的110例ADHD儿童分为注意缺陷为主型(PI)49例,多动或冲动为主型(HI)19例,混合型(CT)42例,对照组儿童35例,对其进行脑电图检查并进行比较。【结果】ADHD组儿童脑电频率明显慢于正常对照组(P<0.05)。三个亚型ADHD患儿中HI型脑电频率最慢,PI型频率最快,三个亚型间两两比较差异有非常显著性(P<0.01)。HI型内右前额、右额部及右枕部的脑电频率明显慢于左半球(P<0.05)。三个亚型在右枕部的脑电频率均慢于左半球。【结论】ADHD存在有一定的神经生理基础,其发病机制可能与大脑发育不成熟有关。[Objective] To study the brain electrical activity between subtypes of attention deficit hyperactivity disorder（ADHD） and normal children. [Methods] 110 children with ADHD （PI type：49,HI type：19,CT type：42） diagnosed by DSM-Ⅳ and 35 normal children as control group. EEG measure was done in each study object and was compared. [Results] Brain wave [requency in ADHD group was obvious slower than that o[ control group（P〈0.05）. Between three subtypes of ADHD,brain wave frequency of HI type was the slowest,of the PI type was the fastest（P〈0.01）. The brain wave frequency of the right forehead,the right brow part and the right pillow part were obvious slower than that of left hemishere （P＇~0.05）. [Conclusion] ADHD exists the certain nerve physiology basic, its pathogenesis might have something to do with brain cortex growth not mature.
