Changes of Visual Networks at Resting State in Children with Attention Deficit Hyperactivity Disorder

Attention deficit hyperactivity disorder (ADHD) characterized by hyperactive, impulsive, and/or inattentive behaviors is one of the most common childhood disorder. ADHD has frequently been associated with changes in resting-state functional connectivity. In last two decades, blood oxygen level dependent (BOLD) fMRI has become an important neuroscientific tool because of ability to image brain function. In this current study, we examined functional connectivity within various visual networks occuring at resting state in children with and without ADHD. It is performed by independent component analysis within group analysis. We found four independent components (ICs) which are included of visual networks. Significant differences were obtained in activation regions of visual networks. The study aimed to contribute to the characterization of ADHD by identifying the specific changes that occur in the visual networks which include of resting state networks.
