Mehta, Mitul A.; Goodyer, Ian M.; Sahakian, Barbara J. – Journal of Child Psychology and Psychiatry, 2004
Objective: Catecholamine stimulant drugs are highly efficacious treatments for attention deficit/hyperactivity disorders (AD/HD). Catecholamine modulation in humans influences performance of numerous cognitive tasks, including tests of attention and working memory (WM). Clear delineation of the effects of methylphenidate upon such cognitive…
