However, questions remain regarding the neural underpinnings of these impairments. To investigate novel neural mechanisms that may support these neurocognitive abnormalities, the present study applied a graph analysis to resting-state functional magnetic resonance imaging (fMRI) data collected from a national sample of 4,781 youth, ages 9-10, who participated in the baseline session of the Adolescent Brain Cognitive Development(SM) Study (ABCD Study®). Analyses were then conducted to examine the relationships among levels of CD symptomatology, metrics of global topology, node-level metrics for subcortical structures, and performance on neurocognitive assessments. Youth higher on CD displayed higher global clustering (Î2= .039, 95% CI(corrected) [.0027 .0771]), but lower Degree(subcortical) (Î2= -.052, 95% CI(corrected) [-.0916 -.0152]). Youth higher on CD had worse performance on a general neurocognitive assessment (Î2= -.104, 95% CI [-.1328 -.0763]) and an emotion recognition memory assessment (Î2= -.061, 95% CI [-.0919 -.0290]). Finally, global clustering mediated the relationship between CD and general neurocognitive functioning (indirect Î2= -.002, 95% CI [-.0044 -.0002]), and Degree(subcortical) mediated the relationship between CD and emotion recognition memory performance (indirect Î2= -.002, 95% CI [-.0046 -.0005]). CD appears associated with neuro-topological abnormalities and these abnormalities may represent neural mechanisms supporting CD-related neurocognitive disruptions.
