The Neuropsychology of Attention Deficit Hyperactivity Disorder.

A literature search at the end of 2003 revealed more than 200 published studies that compared groups with and without attention deficit hyperactivity disorder (ADHD) on neuropsychological measures. This rapid accumulation of new knowledge illustrates the potential utility of neuropsychological methods as a tool to refine our understanding of the pathophysiology of ADHD. Yet these studies also underscore the complexity of the neuropsychology of ADHD, and clearly demonstrate how much remains to be learned. [ABSTRACT FROM AUTHOR]
