Abstract

This article is a brief update on the cognitive bases of Attention Deficit and Hyperactivity Disorder (ADHD). We show some of our recent results in which we analyze cognitive strategies and neurophysiological effect of psychostimulants in this disorder. We sumarize a model, based on our own results and those of other laboratories, in which the attention strategy of ADHD subjects is characterized by a wide spatial frame but a narrow time window compared to controls. Finally, we suggest lines of basic-clinical research for this syndrome
