To summarize recent research on developmental coordination disorder (DCD), with particular attention to comorbidity and related questions of etiology.
Although a general consensus on the disorder definition exists, case identification in research studies remains problematic. Despite this, recent research has reported high levels of attention deficit/hyperactivity disorder and internalizing disorders among children with poor motor coordination. These findings offer some support for the longstanding view that DCD may be one facet of a broader syndrome that includes learning difficulties and deficits in attention. 'Pure' cases are common, however, and other work suggests that DCD and attention deficit/hyperactivity disorder have distinct causes. There is also some evidence that internalizing disorder may be a consequence of DCD.
Measurement issues in DCD persist, whereas findings on comorbidity have both illuminated the nature of the disorder and heightened debate on its usefulness as a distinct diagnostic entity.
总结发育性协调障碍（DCD）的最新研究，特别关注共病及相关病因问题。
尽管对该疾病的定义已经达成共识，但在研究中确定病例仍存在问题。尽管如此，最近的研究报告称，运动协调能力差的儿童中，注意力缺陷/多动障碍和内化障碍的发病率很高。这些发现为长期存在的观点提供了一些支持，即 DCD 可能是包括学习困难和注意力缺陷在内的更广泛综合征的一个方面。然而，“纯”病例很常见，其他研究表明，DCD 和注意力缺陷/多动障碍有不同的病因。也有一些证据表明，内化障碍可能是 DCD 的结果。
DCD 中的测量问题仍然存在，而关于共病的研究结果既阐明了该疾病的性质，也加剧了关于其作为一个独立诊断实体的有用性的争论。
