Motor competence and balance control also appear to be differentially affected between children with ADHD and FASD. Although both clinical groups of children show similar levels of impairment on tasks targeting complex motor skills and static balance, children with ADHD are more likely than children with FASD to show severe impairment on basic cerebellar motor control functions (Kooistra, et al., 2009). These findings suggest that children with ADHD exhibit problems with both basic and complex motor and balance skills, while children with FASD have relatively intact basic motor skills but struggle to integrate these functions into coordinated, complex motor skills.
