Shared and disorder‐specific prefrontal abnormalities in boys with pure attention‐deficit/hyperactivity disorder compared to boys with pure CD during interference inhibition and attention allocation

Abstract

This study shows shared dysfunction in both patients groups in right hemispheric temporal and parietal brain regions during interference inhibition and in right dorsolateral prefrontal cortex during attention allocation. Ventrolateral prefrontal dysfunction, however, was specific to ADHD and not observed in patients with CD in the context of attention allocation. The findings suggest that the typically reduced functional activation in patients with ADHD in ventrolateral prefrontal cortex may be specific to the disorder, at least when compared to patients with CD.
