摘要

目的:探讨成人注意缺陷多动障碍(ADHD)的脑电位指标。方法:为了开发客观的、基于实验室的测试,以帮助建立ADHD诊断,对一组成年人的大脑分神指标进行了调查。我们在一个强迫选择的视觉任务中使用了事件相关脑电位(ERPs)和表现测量。结果:ADHD组行为异常注意力不集中显著增高。在分心的三个ERP成分:N1增强、P300 (P3a)和重新定向负性(RON)中,ADHD和匹配对照组在RON的振幅上存在显著差异。我们使用非参数随机化测试,使我们能够在统计上验证组间差异。结论:我们这项可行性研究的主要结果表明,在与听觉分心相关的其他ERP成分中,RON反应是有希望的指标,可以作为成人ADHD患者注意力重新定向缺陷的潜在生物标志物。

Deficiency in Re-Orienting of Attention in Adults with Attention-Deficit Hyperactivity Disorder.

Objective: To characterize potential brain indexes of attention deficit hyperactivity disorder (ADHD) in adults. Methods: In an effort to develop objective, laboratory-based tests that can help to establish ADHD diagnosis, the brain indexes of distractibility was investigated in a group of adults. We used event-related brain potentials (ERPs) and performance measures in a forced-choice visual task. Results: Behaviorally aberrant distractibility in the ADHD group was significantly higher. Across three ERP components of distraction: N1 enhancement, P300 (P3a), and Reorienting Negativity (RON) the significant difference between ADHD and matched controls was found in the amplitude of the RON. We used non-parametric randomization tests, enabling us to statistically validated this difference between-group. Conclusions: Our main results of this feasibility study suggest that among other ERP components associated with auditory distraction, the RON response is promising index for a potential biomarker of deficient re-orienting of attention in adults s with ADHD.
