This note re-examines a finding by Crow et al. [Crow, T. J., Crow, L. R., Done, D. J., & Leask, S. (1998). Relative hand skill predicts academic ability: Global deficits at the point of hemispheric indecision
Abstract:
This note re-examines a finding by Crow et al. [Crow, T. J., Crow, L. R., Done, D. J., & Leask, S. (1998). Relative hand skill predicts academic ability: Global deficits at the point of hemispheric indecision. Neuropsychologia, 36(12), 1275-1281] that equal skill of right and left hands is associated with deficits in cognitive ability. This is consistent with the idea that failure to more...

The aim of this study was to examine the association of methionine allele of the COMT polymorphism which impairs prefrontal cognition in children and adolescents with attention-deficit hyperactivity disorder
Abstract:
ADHD is a highly heritable psychiatric disorder of childhood. A functional polymorphism (Val158Met) of the catechol-O-methyltransferase (COMT) gene has attracted interest as a candidate gene for ADHD. The high-activity valine variant of this polymorphism degrades prefrontal dopamine three to four times more quickly than the low-activity methionine variant and could therefore contribute more...
