599. ADHD药物的作用真相:清醒与奖赏而非专注

from 知为谁 · host 知为谁

最新的研究揭示了 ADHD(注意力缺陷多动障碍)药物 的运作机制可能与传统认知完全不同。虽然这些药物通常被认为能增强大脑的专注力,但神经影像学显示,它们实际上是通过刺激大脑的奖赏与觉醒系统来发挥作用的。这种变化让患者感到更加警觉和充满动力,从而使原本乏味的任务变得更具吸引力。值得注意的是,这些药物产生的效果与充足的睡眠极为相似,甚至能掩盖长期睡眠不足带来的负面表现。因此,研究人员建议在诊断 ADHD 时应优先评估患者的睡眠质量,以避免误诊或过度用药。这一发现提示我们,提高表现并不一定等同于修复了注意力系统,而可能是增强了对任务的投入感和精神活力。内容来源:https://www.sciencedaily.com/releases/2025/12/251225235942.htm
