Local functional connectivity suggests functional immaturity in children with attention‐deficit/hyperactivity disorder
Previous studies have associated Attention‐Deficit/Hyperactivity Disorder (ADHD) with a maturational lag of brain functional networks. Functional connectivity of the human brain changes from primarily local to more distant connectivity patterns during typical development. Under the maturational lag...

| description | Previous studies have associated Attention‐Deficit/Hyperactivity Disorder (ADHD) with a maturational lag of brain functional networks. Functional connectivity of the human brain changes from primarily local to more distant connectivity patterns during typical development. Under the maturational lag hypothesis, we expect children with ADHD to exhibit increased local connectivity and decreased distant connectivity compared with neurotypically developing (ND) children. We applied a graph‐theory method to compute local and distant connectivity levels and cross‐sectionally compared them in a sample of 120 children with ADHD and 120 age‐matched ND children (age range = 7–17 years). In addition, we measured if potential group differences in local and distant connectivity were stable across the age range considered. Finally, we assessed the clinical relevance of observed group differences by correlating the connectivity levels and ADHD symptoms severity separately for each group. Children with ADHD exhibited more local connectivity than age‐matched ND children in multiple brain regions, mainly overlapping with default mode, fronto‐parietal and ventral attentional functional networks (p |
