  Purpose

Minimum 24 subjects aged 8-12 with a diagnosis of ADHD will be prescribed extended release guanfacine (Intuniv) to assess impact, if any, on working memory. Pre and post testing using a standardized battery of tests for effect on symptoms of ADHD and working memory will be administered and assessed.
