TL;DR: This large-scale longitudinal pediatric neuroimaging study confirmed linear increases in white matter, but demonstrated nonlinear changes in cortical gray matter, with a preadolescent increase followed by a postadolescent decrease.

TL;DR: Maturation to progress in a similar manner regionally in both children with and without ADHD, with primary sensory areas attaining peak cortical thickness before polymodal, high-order association areas, and there was a marked delay in ADHD in attainingpeak thickness throughout most of the cerebrum.

TL;DR: Developmental trajectories for all structures, except caudate, remain roughly parallel for patients and controls during childhood and adolescence, suggesting that genetic and/or early environmental influences on brain development in ADHD are fixed, nonprogressive, and unrelated to stimulant treatment.

TL;DR: Findings provide evidence for a gradual maturation, during late childhood and adolescence, of fiber pathways presumably supporting motor and speech functions.

TL;DR: This largest longitudinal pediatric neuroimaging study reported to date demonstrates the importance of examining size-by-age trajectories of brain development rather than group averages across broad age ranges when assessing sexual dimorphism and finds robust male/female differences in the shapes of trajectories.
