Abstract

Autism spectrum disorder (ASD) is consistently associated with alterations in brain connectivity, but there are conflicting results as to where and when individuals with ASD display increased or reduced functional connectivity. Such inconsistent findings may be driven by atypical neurodevelopmental trajectories in ASD during adolescence, but no longitudinal studies to date have investigated this hypothesis. We thus examined the functional connectivity of three neurocognitive resting‐state networks—the default mode network (DMN), salience network, and central executive network (CEN)—in a longitudinal sample of youth with ASD (n = 16) and without ASD (n = 22) studied during early/mid‐ and late adolescence. Functional connectivity between the CEN and the DMN displayed significantly altered developmental trajectories in ASD: typically developing (TD) controls—but not youth with ASD—exhibited an increase in negative functional connectivity between these two networks with age. This significant interaction was due to the ASD group displaying less negative functional connectivity than the TD group during late adolescence only, with no significant group differences in early/mid‐adolescence. These preliminary findings suggest a localized age‐dependency of functional connectivity alterations in ASD and underscore the importance of considering age when examining brain connectivity.

Lay Summary: Brain connectivity may develop differently during adolescence in youth with autism spectrum disorder (ASD). We looked at changes in brain connectivity over time within individuals and found that, for some brain regions, adolescents with ASD did not show the same changes in brain connectivity that typically developing adolescents did. This suggests it is important to consider age when studying brain connectivity in ASD.

  • In resting state functional connectivity MRI studies, evidence has emerged of both hyper-connectivity and hypo-connectivity in short-range and long-range connections throughout the brain in ASD.

    From Autism spectrum disorder (2020) · cites this paper as [81]

    The Introduction (page unavailable) reports that resting-state functional connectivity studies in ASD have found both hyperconnectivity and hypoconnectivity. It does not establish the claim’s further specificity that both occur in short-range and long-range connections throughout the brain; the paper focuses on selected resting-state networks.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
