To highlight recent advances in the conceptualization of attention-deficit hyperactivity disorder (ADHD) emerging from neuroimaging and endophenotypic approaches.
We selectively reviewed recent published literature on the phenomena of resting-state functional connectivity, intrasubject variability, and diffusion tensor imaging pertaining to ADHD.
Recent advances based on the novel approach of resting-state functional connectivity appear to be highly promising and likely to link to studies of intrasubject variability.
Endophenotypic fractionation may offer a means of addressing the complex heterogeneity of ADHD on the path to testable models of pathophysiology. Such models focusing on intrasubject variability, intrinsic brain activity, and reward-related processing are progressing rapidly.
突出神经影像学和内表型方法在注意力缺陷多动障碍(ADHD)概念化方面的最新进展。
我们选择性地回顾了有关 ADHD 的静息态功能连接、个体内变异性和弥散张量成像现象的最新发表的文献。
基于静息态功能连接的新方法的最新进展似乎很有希望,并可能与个体内变异性的研究联系起来。
内表型分离可能为 ADHD 的复杂异质性提供一种途径,以建立可测试的病理生理学模型。这种关注个体内变异性、内在大脑活动和与奖励相关的处理的模型正在迅速发展。
