News Finding: "It is particularly noteworthy that the networks we found to have lagging maturation in ADHD are linked to the very behaviors that are the symptoms of ADHD," he says.
Paper Finding: We found prominent maturational lag in DMN interconnections with VAN, with a concentration of lagged connections involving anterior insula, a key hub in VAN.
News Context: These networks, and the connections between them, mature throughout early childhood all the way to young adulthood. "It is particularly noteworthy that the networks we found to have lagging maturation in ADHD are linked to the very behaviors that are the symptoms of ADHD," he says. "The results of this study set the stage for the next phase of this research, which is to examine individual components of the networks that have the maturational lag," he says.
Paper Context: Our results thus add to this network regulation model of ADHD by suggesting a developmental explanation for the observed pattern of network and regional abnormalities. We found prominent maturational lag in DMN interconnections with VAN, with a concentration of lagged connections involving anterior insula, a key hub in VAN. These observations suggest that lagged maturation in anterior insula could contribute to several forms of inattention in ADHD.
