![]() ![]() ![]() As a result of motor skill impairments, children with DCD have poorer academic achievement, and reduced participation in self-care, social, and leisure activities ( Zwicker et al., 2013 Izadi-Najafabadi et al., 2019). DCD significantly impairs a child’s ability to learn motor skills and to perform everyday activities, such as getting dressed, tying shoelaces, or riding a bicycle ( Zwicker et al., 2012). Given the cerebellum’s involvement in internal models of movement, results of this study may help to explain why children with DCD struggle to learn motor skills.ĭevelopmental Coordination Disorder (DCD) is a neurodevelopmental disorder that affects ∼450,000 Canadian children, or roughly 1-to-2 children in every classroom ( American Psychiatric Association, 2013 Statistics Canada, 2020). These findings indicate that reductions in cerebellar grey matter volume are associated with poorer motor skills. Further, Pearson correlations revealed significant positive associations between the total motor percentile score on the Movement Assessment Battery for Children-2 and regions that had reduced grey matter volume in our cohort (brainstem, left crus I, right VIIb, and right VIIIa). Results revealed that children with DCD had reduced grey matter volume in several regions, namely: the brainstem, right/left crus I, right crus II, left VI, right VIIb, and right VIIIa lobules. Forty-six children (12 typically-developing and 34 with DCD) were investigated using high resolution T1-weighted images, which were then processed using the spatially unbiased atlas template of the cerebellum and brainstem (SUIT) toolbox for a region of interest-based examination of the cerebellum. Using voxel-based morphometry, we assessed cerebellar morphology in children 8–12 years of age. The purpose of our study was to examine cerebellar differences in children with DCD compared to typically-developing children. While the cerebellum has been hypothesised to be involved in developmental coordination disorder, no studies have specifically examined cerebellar structure in this population. The cause of DCD is unknown however, evidence suggests that children with DCD have altered brain structure and function. 5Department of Pediatrics, The University of British Columbia, Vancouver, BC, Canadaĭevelopmental coordination disorder (DCD) is a neurodevelopmental disorder that significantly impairs a child’s ability to learn motor skills and to perform everyday activities.4Department of Occupational Science and Occupational Therapy, The University of British Columbia, Vancouver, BC, Canada.3Department of Radiology, The University of British Columbia, Vancouver, BC, Canada.2Brain, Behaviour, and Development Theme, British Columbia Children’s Hospital Research Institute, Vancouver, BC, Canada.1Department of Rehabilitation Sciences, The University of British Columbia, Vancouver, BC, Canada. ![]()
