This study aims to describe the 24-hour activity rhythm in adults with attention-deficit/hyperactivity disorder (ADHD). A total of 18 ADHD patients and 37 healthy controls (HCs) wore an actigraph for 7 days. ADHD patients showed higher motor activity than HCs at 4:00, 6:00, 15:00 and 16:00 hour. Within the theoretical framework of the two-process model of sleep regulation, the observed data may be explained by lower homeostatic sleep pressure in ADHD. This could lead to an increase in motor activity in the second half of the night, when sleep need decreases more rapidly, and in the first half of the afternoon, when patients do not experience the typical post-lunch dip.
本研究旨在描述注意缺陷多动障碍（ADHD）成人患者的24小时活动节律。共有18名ADHD患者和37名健康对照者（HCs）佩戴活动记录仪7天。ADHD患者在4:00、6:00、15:00和16:00时的运动活动高于HCs。在睡眠调节双过程模型的理论框架内，观察到的数据可能是由于ADHD患者较低的稳态睡眠压力所致。这可能导致在下半夜睡眠需求下降更快时以及在下午上半叶患者未经历典型的午餐后嗜睡时运动活动增加。
