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: These findings across imaging modalities underscore a broader point: the functional abnormalities we observed within and between DMN and TPNs are likely to be part of a larger picture of developmental delays of structural characteristics such as cortical thickness and white matter tracts (see ref.
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: found diffuse maturational delay in cortical thickness in ADHD, with peak delays in medial prefrontal regions in DMN. These findings across imaging modalities underscore a broader point: the functional abnormalities we observed within and between DMN and TPNs are likely to be part of a larger picture of developmental delays of structural characteristics such as cortical thickness and white matter tracts (see ref. Joint, multimodal investigation of this ensemble of structural and functional characteristics in ADHD could provide insights into the mechanisms that produce and sustain the disorder.
