本研究探讨了两种亚型的注意缺陷多动障碍（ADHD）儿童和正常对照组之间的脑电图差异。在闭眼休息条件下记录EEG，并进行傅立叶变换，以提供δ、θ、α和β频带的绝对和相对功率估计值，并计算每个频带的平均频率。还计算了频带之间的比率系数。在所有三组之间的θ、α和β带中发现了平均组差异。同样，三组之间的θ/α和θ/β比值以及总EEG的平均频率也存在差异。这些结果支持ADHD的模型是由发育偏差而不是中枢神经系统的成熟滞后引起的。临床组之间额叶活动的差异表明不同的神经解剖系统参与了ADHD的不同亚型。
This study investigated EEG differences between children with two subtypes of Attention-Deficit/Hyperactivity Disorder (ADHD) and normal control subjects. EEG was recorded during an eyes-closed resting condition and Fourier transformed to provide absolute and relative power estimates for the delta, theta, alpha, and beta bands, and the mean frequency for each band was calculated. Ratio coefficients were also calculated between frequency bands. Mean group differences were found in the theta, alpha, and beta bands between all three groups. Similarly, differences were found between all three groups for the theta/alpha and theta/beta ratios and for the mean frequency of the total EEG. These results support a model of ADHD resulting from a developmental deviation rather than a maturational lag in the central nervous system. Differences between the clinical groups in frontal activity suggest that different neuroanatomical systems are involved in the different subtypes of ADHD.
