Frontal White Matter Microstructural Differences Predict Cognitive and Behavioral Impulsivity in ADHD

This study examined ADHD-control group differences in white matter (WM) in a large sample of well-characterized pre-adolescent children. We hypothesized widespread WM alterations in ADHD and that alterations in frontal WM connections would correlate with behavioral and cognitive impulsivity. Results confirm this, thus clarify the nature of ADHD WM differences.
