abstract = {Background: Autism spectrum disorder (ASD) is a common
neurodevelopmental diagnosis showing substantial phenotypic
heterogeneity. A leading example can be found in verbal and
nonverbal cognitive skills, which vary from elevated to
impaired compared with neurotypical individuals. Moreover,
deficits in verbal profiles often coexist with normal or
superior performance in the nonverbal domain.Methods: To
study brain substrates underlying cognitive imbalance in
ASD, we capitalized categorical and dimensional IQ profiling
as well as multimodal neuroimaging.Results: IQ analyses
revealed a marked verbal to nonverbal IQ imbalance in ASD
across 2 datasets (Dataset-1: 155 ASD, 151 controls;
Dataset-2: 270 ASD, 490 controls). Neuroimaging analysis in
Dataset-1 revealed a structure-function substrate of
cognitive imbalance, characterized by atypical cortical
thickening and altered functional integration of language
networks alongside sensory and higher cognitive
areas.Conclusion: Although verbal and nonverbal intelligence
have been considered as specifiers unrelated to autism
diagnosis, our results indicate that intelligence
disparities are accentuated in ASD and reflected by a
consistent structure-function substrate affecting multiple
brain networks. Our findings motivate the incorporation of
cognitive imbalances in future autism research, which may
help to parse the phenotypic heterogeneity and inform
intervention-oriented subtyping in ASD.},
