Purpose of Study 

This double-blind crossover study aims to compare cognitive performance (e.g., working memory, selective attention and cognitive flexibility) of children ages 6-18 years diagnosed with ADHD of the combined type (ADHD-C) or inattentive-type (ADHD-IA) and currently on > 20 mg/day of psychostimulants (psychostimulants) on: a) their current dose of psychostimulants, vs. b) a lower-dose of psychostimulants (half of their current dose).

The investigators hypothesize that the lower-dose psychostimulants will result in better cognitive performance than moderate-to-high doses of psychostimulants.
