Attention Deficit Disorder With Hyperactivity Clinical Trial
Official title:
Cortical Excitability: Phenotype and Biomarker in ADHD Therapy
The purpose of this study is to find out if children with attention-deficit, hyperactivity disorder (ADHD) have a difference in how their brain cells "fire" or react. The investigators also want to find if brain cell "firing" can tell us how severe of symptoms a child has from ADHD. Finally, the investigators want to see if giving an ADHD medication called atomoxetine can make the ADHD symptoms in a child better and if the improvement shows a change in brain "firing".
This study will evaluate Short Interval Intracortical Inhibition (SICI) measured by pTMS as a marker of the hyperactive-impulsive dimension in 120 ADHD 7-12 years, medication-free children. This study will characterize the effects of a single dose of atomoxetine compared to placebo on cognitive correlates of SICI change. Participants will be randomized 2:1 to either atomoxetine or placebo. The study will also characterize the effects of four weeks of atomoxetine treatment on cortical inhibition and will correlate SICI change with clinical outcomes. ;
