Cerebral dominance and cerebral asymmetries on computed tomogram in childhood

Hand preference assessment and computed tomography (CT) were used in 94 children to determine whether cerebral morphologic asymmetries were closely correlated with handedness, as reported for adults. We found that parent-reported hand preference and tested hand preference were highly correlated. Eighty-two percent of the CTs showed asymmetry between the hemispheres, but there was no significant correlation between hemispheric configuration and any measure of handedness. Although there may be a statistical relationship between cerebral configuration and handedness in large groups of subjects, hemispheric asymmetries found on routine CT of the head cannot serve as predictors of cerebral dominance in children.
