Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a double-blind, placebo-controlled study using daily doses of up to 1.3 mg/kg/day of Concerta in the treatment of adults with the DSM-IV diagnosis of attention deficit hyperactivity disorder (ADHD) (childhood onset). We hypothesize ADHD symptomatology in adults with DSM-IV ADHD will be responsive to Concerta treatment and Concerta-associated response of ADHD symptomatology in adults will be sustained over time.
