OBJECTIVE We examined differences between those with and without ADHD symptoms on resting state electroencephalography (EEG) indices and unique relations with sluggish cognitive tempo (SCT) symptoms. METHOD Children with ADHD symptoms ( n = 21) and healthy controls ( n = 20) were assessed using rating scales, a neuropsychological task measuring sustained attention and inhibitory control, and EEG activity during a resting state period. Between-group, correlational, and regression analyses were conducted. RESULTS Large differences (particularly for theta/beta ratio in frontal and frontocentral regions) were found on EEG measures between those with and without ADHD symptoms. While ADHD and SCT symptoms both related to sustained attention on a computerized task, only ADHD symptoms were related to frontal and frontocentral theta/beta ratio. CONCLUSION Results support the conclusion that ADHD symptoms are strongly associated with theta/beta ratio in frontal and frontocentral regions. Future studies should explore unique neurophysiological correlates of SCT.

对患有和不患有ADHD症状的儿童进行的EEG研究：组间差异和与缓慢的认知节奏症状相关。

目的我们研究了静息状态脑电图（EEG）指数上有和没有ADHD症状的人之间的差异，以及与迟钝的认知节奏（SCT）症状的独特关系。方法使用评定量表，测量持续注意力和抑制控制的神经心理学任务以及静息状态下的脑电图活动来评估患有ADHD症状（n = 21）和健康对照组（n = 20）的儿童。进行了组间，相关和回归分析。结果在有和没有ADHD症状的人之间，脑电图测量结果存在较大差异（特别是额叶和额中部区域的θ/β比）。尽管ADHD和SCT症状都与持续关注计算机任务有关，但只有ADHD症状与额叶和额中央θ/β比有关。结论结果支持以下结论：ADHD症状与额叶和额中部区域的θ/β比值密切相关。未来的研究应探索SCT独特的神经生理相关性。
