Motor coordination and emotional–behavioral problems in children

Purpose of review To summarize recent research on developmental coordination disorder (DCD), with particular attention to comorbidity and related questions of etiology. Recent findings 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. Summary 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.
