Decreased functional concordance in male children with autism spectrum disorder / Sha WANG ; Zaifa XUE ; Jing LIU ; Xiaoxia NIU ; Le GAO ; Xiaonan GUO in Autism Research, 16-12 (December 2023)

Titre : Decreased functional concordance in male children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Sha WANG, Auteur ; Zaifa XUE, Auteur ; Jing LIU, Auteur ; Xiaoxia NIU, Auteur ; Le GAO, Auteur ; Xiaonan GUO, Auteur Article en page(s) : p.2263-2274 Index. décimale : PER Périodiques Résumé : Abstract Autism spectrum disorder (ASD) is an early-onset neurodevelopmental condition with altered function of the brain. At present, a variety of functional metrics from neuroimaging techniques have been used to explore ASD neurological mechanisms. However, the concordance of these functional metrics in ASD is still unclear. This study used resting-state functional magnetic resonance imaging data, which were obtained from the open-access Autism Brain Imaging Data Exchange database, including 105 children with ASD and 102 demographically matched typically developing (TD) children. Both voxel-wise and volume-wise functional concordance were calculated by combining the dynamic amplitude of low-frequency fluctuations, dynamic regional homogeneity, and dynamic global signal correlation. Furthermore, a two-sample t-test was performed to compare the functional concordance between ASD and TD groups. Finally, the relationship between voxel-wise functional concordance and Autism Diagnostic Observation Schedule subscores was analyzed using the multivariate support vector regression in the ASD group. Compared with the TD group, we found that ASD showed decreased voxel-wise functional concordance in the left superior temporal pole (STGp), right amygdala, and left opercular part of the inferior frontal gyrus (IFGoper). Moreover, decreased functional concordance was associated with restricted and repetitive behaviors in ASD. Our results found altered brain function in the left STGp, right amygdala, and left IFGoper in ASD by functional concordance, indicating that functional concordance may provide new insights into the neurological mechanisms of ASD.
