Differences in Brain Structural Covariance Network Characteristics in Children and Adults With Autism Spectrum Disorder / Suping CAI in Autism Research, 14-2 (February 2021)
[article]
Titre : Differences in Brain Structural Covariance Network Characteristics in Children and Adults With Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Suping CAI, Auteur ; Xuwen WANG, Auteur ; Fan YANG, Auteur ; Dihui CHEN, Auteur ; Liyu HUANG, Auteur Article en page(s) : p.265-275 Langues : Anglais (eng) Mots-clés : autism spectrum disorder brain development graph theoretical analysis sliding window analysis structural magnetic resonance neuroimaging structure covariance network Index. décimale : PER Périodiques Résumé : Systematically describing the structural topological configuration of human brain during development is an essential task. Autism spectrum disorder (ASD) represents a powerful challenge for psychiatry and neuroscience researchers. In this study, we investigated variations in the structural covariance network properties of 441 patients with ASD ranging in age from 7 to 45?years and in 426 age-matched healthy controls (HCs) using structural magnetic resonance neuroimaging from the ABIDE database. We applied a sliding window approach to study topological variation during development using comprehensive graph theoretical analysis. The main findings are as follows: (1) Cross-sectional trajectories of the network characteristics exhibited inverted U-shapes in both HCs and participants with ASD, with the latter exhibiting a 7-year delay in reaching the maximum value, (2) network resilience to targeted attacks peaked at 18' and 19' in the HCs and at 25' in the participants with ASD, and the weakest resilience occurred at age 7', (3) the HCs and participants with ASD exhibited normalized mean degree differences in the right amygdala, and (4) significant differences in the network characteristics were observed in the 18' age group at most of the densities analyzed. We used cross-sectional analysis to infer distinct neurodevelopmental trajectories in ASD in the brain structural connectome. Our findings are consistent with the notion that adolescence is a sensitive period of brain development with strong potential for brain plasticity, offering opportunities for environmental adaptation and social integration and for increasing vulnerability. ASD may be a product of susceptibility. LAY SUMMARY: We used cross-sectional analysis to preliminarily infer distinct neurodevelopmental trajectories in ASD in the brain structural connectome.
