Descriptive Information
Brief Title  ICMJE Effect of Omega-3 Fatty Acid on Cortical Function in ADHD
Official Title  ICMJE Docosahexaenoic Acid Augmentation of Cortical Attention Networks in ADHD
Brief Summary The study hypothesis is that DHA is more effective than placebo in increasing brain activation and reducing symptoms in psychostimulant-free children with ADHD.
Detailed Description This study aims to determine the effects of 10-week dietary supplementation with the long-chain omega-3 fatty acid docosahexaenoic acid (DHA) or placebo on prefrontal cortical structural and functional connectivity using several neuroimaging techniques: DTI (Diffusion Tensor Imaging), 1H MRS(Proton Magnetic Resonance Spectroscopy), and fMRI (Functional Magnetic Resonance Imaging) in psychostimulant-free children with attention deficit hyperactivity disorder (ADHD). It is postulated that DHA supplements will increase brain activation and reduce ADHD symptomatology.
