Milich、Balentine 和 Lynam 认为注意力不集中型 ADHD 是一种与组合型不同且无关的疾病，这一观点值得仔细研究。在评论了验证综合症和疾病的最佳方法后，我同意 Milich 等人的观点。根据目前的定义，注意力不集中类型既包括处于组合类型阈值以下的儿童，也包括表现出认知速度缓慢和活动不足的儿童。很可能，只有后一个亚组在任何定性意义上都可能与当前的多动症概念不同。然而，对于一个关键的标准变量，即认知处理/神经心理功能，目前几乎没有明确的证据可以明确区分。在分类学允许更好的表型区分（包括更广泛的症状来指示注意力不集中）之前，研究将继续混淆这两个亚组，排除它们之间可能的遗传、心理生物学、神经心理学、认知、家族、发育和治疗相关的区别方面的进展。米利奇等人。促进了对发展精神病理学这一关键方面的诊断重新制定和外部验证的必要研究。
The contention of Milich, Balentine, and Lynam that the inattentive type of ADHD is a disorder distinct from and unrelated to the combined type bears scrutiny. After commenting on the optimal means of validating syndromes and disorders, I concur with Milich et al. that, under current definitions, the inattentive type subsumes both children who are subthreshold for the combined type and those who display sluggish cognitive tempo and underactivity. In all probability, only the latter subgroup may be distinct, in any qualitative sense, from current conceptions of ADHD. Yet with respect to a key criterion variable, cognitive processing/neuropsychological functioning, there is currently little definitive evidence for clear differentiation. Until nosologies allow for better phenotypic differentiation, which includes broader sets of symptoms to index inattentiveness, research will continue to confound these two subgroups, precluding advances regarding possible genetic, psychobiologic, neuropsychologic, cognitive, familial, developmental, and treatment-related distinctions between them. Milich et al. have prompted needed research on diagnostic reformulations and external validation regarding this crucial aspect of developmental psychopathology.
