Years of research have added to our understanding of Attention Deficit Hyperactivity Disorder (ADHD). None-the-less there is still much that is poorly understood. There is a need for, and ongoing interest in, developing a deeper understanding of this disorder to optimally identify risk and better inform treatment. Here, we present a compilation of findings examining ADHD both behaviorally and using neurophysiologic markers. Drawing on early work of McIntosh and co-investigators, we examined response to sensory challenge in children with ADHD, measuring HPA activity and electrodermal response (EDR) secondary to sensory stressors. In addition, we have examined the relationship between these physiologic measures, and reports of behavioral sensory over-responsivity and anxiety. Findings suggest that sensory responsivity differentiates among children with ADHD and warrants consideration. We link these findings with research conducted both prior to and after our own work and emphasize that there a growing knowledge supporting a relationship between ADHD and sensory over-responsivity, but more research is needed. Given the call from the National Institute of Health to move toward a more dimensional diagnostic process for mental health concerns, and away from the more routine categorical diagnostic process, we suggest sensory over-responsivity as a dimension in the diagnostic process for children with ADHD.

感觉过度反应是多动症的一个附加维度。

多年的研究加深了我们对注意力缺陷多动障碍 (ADHD) 的了解。尽管如此，仍有许多问题尚不清楚。人们需要并且持续关注对这种疾病进行更深入的了解，以最佳地识别风险并更好地为治疗提供信息。在这里，我们展示了通过行为和神经生理学标记检查多动症的研究结果汇编。借鉴 McIntosh 和合作研究人员的早期工作，我们检查了 ADHD 儿童对感觉挑战的反应，测量了继发于感觉应激源的 HPA 活动和皮肤电反应 (EDR)。此外，我们还研究了这些生理测量与行为感觉过度反应和焦虑的报告之间的关系。研究结果表明，多动症儿童的感觉反应能力存在差异，值得考虑。我们将这些发现与我们自己工作之前和之后进行的研究联系起来，并强调越来越多的知识支持多动症和感觉过度反应之间的关系，但还需要更多的研究。鉴于美国国立卫生研究院呼吁对心理健康问题采取更维度的诊断过程，并远离更常规的分类诊断过程，我们建议将感觉过度反应作为多动症儿童诊断过程中的一个维度。
