Heightened motor activity is a hallmark of attention-deficit/hyperactivity disorder (ADHD), yet high activity levels are also often reported in young children with autism spectrum disorder (ASD). It is currently unclear whether increased motor activity represents a distinct versus shared early predictor of ASD and ADHD; no prior studies have directly examined this prospectively. We investigated differences in longitudinal patterns of objectively measured motor activity during early development.

患 ASD 的婴儿客观测量的运动活动模式和对 ADHD 的关注

运动活动增加是注意力缺陷/多动障碍 (ADHD) 的标志，但在患有自闭症谱系障碍 (ASD) 的幼儿中也经常报告高活动水平。目前尚不清楚增加的运动活动是否代表了 ASD 和 ADHD 的独特或共同的早期预测因子；之前没有研究直接对此进行前瞻性检查。我们调查了早期发育过程中客观测量的运动活动纵向模式的差异。
