A generalizable connectome-based marker of in-scan sustained attention in neurodiverse youth

Abstract: Difficulty with attention is an important symptom in many conditions in psychiatry, including neurodiverse conditions such as autism. There is a need to better understand the neurobiological correlates of attention and leverage these findings for individuals in healthcare settings. Nevertheless, it remains unclear if it is possible to build robust dimensional predictive models of attention in neurodiverse populations. Here, we use five datasets to identify and validate functional connectome-based markers of at… Show more

“…There is some literature showing FC differences between HC males and females (Weis et al, 2020), and there are some sex-based differences in the functional correlates of addiction (Nicolas et al, 2022;Smith et al, 2023). Similar effects of neurodiversity and socioeconomic status on FC have been reported (Horien et al, 2023;Sripada et al, 2021;Yaple & Yu, 2020). Therefore, future work should endeavour to include representation of male and female participants, as excluding the consideration of clinically relevant factors from research negatively impacts the clinical relevance of findings (Johnson et al, 2014).…”

“…Edges from connectivity matrices for each subject per scan were correlated to the three aforementioned memory performance measures, totaling to seven connectivity matrices and three memory scores per subject (21 total correlated matrices). Motion and age covariates were also included in the CPM analyses to account for in-scanner head motion, age, and their interaction in our predictions, as previously done (Scheinost et al ., 2021; Dufford et al ., 2022; Horien et al ., 2022).…”

“…To visualize sex differences at the network level, we first split the aforementioned consensus matrix into two binarized matrices (a “positive” matrix containing edge with significant positive correlations to memory and the other “negative” matrix of edges with significant negative correlations to memory) for each predictive model. Categorization of nodes by functional network was determined using the 10-network parcellation of the Shen 268-node atlas (Horien et al ., 2022). In this network grouping, the medial frontal (MF) network also includes some temporal and frontal nodes which often cluster with the DMN.…”
