Brain development in ADHD.

Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder with underlying brain anatomical and functional measures, as well as familial/genetic factors that are major foci of neuropsychiatric research. Advances in imaging technology have shown structural and functional brain differences between individuals with and without ADHD. Longitudinal studies have enabled the elucidation of differences in developmental course. Studies comparing persisting and remitting cases of ADHD are particularly promising. Therapeutic doses of psychostimulants normalize many measures of brain anatomy and function.
