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: This analysis revealed statistically significant negative correlations for all three networks [DMN-DMN (r=-0.18; P = 0.05), DMN-FPN (r=-0.14; P = 0.02), and DMN-VAN (r=-0.21; P = 0.01); all P values from permutation tests].
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: or Conners' Rating Scale, 3rd Edition (39) was available for 180 (ADHD = 77) of the 421 participants in the present analysis (other participants had either different measures of ADHD symptom severity or none at all). This analysis revealed statistically significant negative correlations for all three networks [DMN-DMN (r=-0.18; P = 0.05), DMN-FPN (r=-0.14; P = 0.02), and DMN-VAN (r=-0.21; P = 0.01); all P values from permutation tests]. This result supports the hypothesis that with greater severity of inattention, there is correspondingly greater lag in maturation of DMN and its interconnections with TPNs.
