注意缺陷多动障碍儿童定量脑电图特征研究

目的探讨注意缺陷多动障碍(attention-deficit hyperactivity disorder,ADHD)儿童脑电图的改变。方法对37例临床诊断为ADHD儿童及30例年龄匹配的健康儿童进行定量脑电图分析。记录安静闭目状态下的脑电图,经傅里叶转换得到α1、α2、α3、β、θ频段绝对及相对功率,以及αL/αR、θ/α等。结果 ADHD组较对照组θ活动增加,α、β活动在不同的脑区结果不同,θ/α升高,αL/αR于额部降低。结论 ADHD患儿的脑电图与正常儿童存在着差异。

Study on quantitative electroencephalography characteristics of children with attention-deficit hyperactivity disorder

Objective To investigate the change of quantitative electroencephalography(QEEG) in children with attention-deficit hyperactivity disorder(ADHD). Methods A total of 37 children with ADHD and 30 age-matched controls were included.EEG was recorded during eyes-closed resting condition and Fourier transformed to provide estimates for absolute and relative power in alpha-1,alpha-2,alpha-3,beta,theta frequency bands and alpha-L/alpha-R,theta/alpha,theta/beta. Results Compared with controls,ADHD group was found to have more theta and delta activity,alpha and beta activity were different in different brain region,ADHD groups had higher beta/alpha and higher theta/alpha,control group was found to have higher alpha-L/alpha-R in frontal area. Conclusion There are differences on electroencephalography between ADHD children and controls.
