本研究调查了两组儿童的脑电图差异注意缺陷多动障碍，混合型，有阅读障碍（ADHD + RD）或没有（ADHD）和典型的控制参与者。每组包括20名参与者。AE参与者年龄在8至12岁之间，年龄和性别匹配。在闭眼静息状态下记录21个单极导联的脑电（EEG），并将其分成9个区域进行分析。对EEG进行傅立叶变换，以提供δ、θ、α和β频带的绝对和相对功率估计值。还计算了theta/alpha和theta/beta比率的比率系数。与对照组相比，临床组表现出ADHD文献中常见的慢波活动增加和快波活动减少。ADHD + RD组比ADHD组有更多的相对θ，更少的相对α，以及更高的θ/α比值。在δ和α带中也发现了一些半球差异。这些结果表明，在ADHD + RD组中发现的一些EEG分歧代表与阅读障碍相关的电生理成分，其独立于在ADHD中发现的EEG分歧。
This Study investigated electroencephalographic differences between two groups of children with attention-deficit/hyperactivity disorder, combined type, with reading disabilities (ADHD + RD) or without (ADHD) and typical control participants. Twenty participants were included in each group. AE participants were between the ages of 8 and 12 years, and groups were matched on age and gender. The electroencephalographic (EEG) was recorded during an eyes-closed resting condition from 21 monopolar derivations, which were clustered into nine regions for analysis. The EEGs were Fourier-transformed to provide absolute and relative power estimates for the delta, theta, alpha, and beta bands. Ratio coefficients were also calculated for the theta/alpha and theta/beta ratios. Compared with controls, the clinical groups demonstrated the increased slow-wave and reduced fast-wave activity commonly reported in the ADHD literature. The ADHD + RD group had more relative theta, less relative alpha, and a higher theta/alpha ratio than the ADHD group. A number of hemispheric differences were also found in the delta and alpha bands. These results suggested that some of the EEG divergences found in the ADHD + RD group represent an electrophysiological component associated with the reading disability that is independent of the EEG divergences found in ADHD.
