Abstract

OBJECTIVE: To investigate cerebellar function in autism by measuring visually guided saccades. METHODS: A visually guided saccade task was performed by 46 high-functioning individuals with autism with and without delayed language acquisition, and 104 age and IQ matched healthy individuals. RESULTS: Individuals with autism had increased variability in saccade accuracy, and only those without delayed language development showed a mild saccadic hypometria. Neither autistic group showed a disturbance in peak saccade velocity or latency. CONCLUSIONS: The observed saccadic abnormalities suggest a functional disturbance in the cerebellar vermis or its output through the fastigial nuclei, consistent with reported cerebellar histopathology in autism. The pattern of mild hypometria and variable saccade accuracy is consistent with chronic rather than acute effects of cerebellar vermis lesions reported in clinical and non-human primate studies, as might be expected in a neurodevelopmental disorder. The different patterns of oculomotor deficits in individuals with autism with and without delayed language development suggest that pathophysiology at the level of the cerebellum may differ depending on an individual's history of language development.

  • Gaze linked to cerebellar function is characteristically atypical in individuals with autistic disorder, and subtle oculomotor alterations suggest abnormalities in cortico-cerebellar connectivity.

    “Gaze linked to cerebellar function [23] is characteristically atypical in individuals with AD and the observation of subtle oculomotor alterations suggests abnormalities in cortico-cerebellar connectivity [24, 25].”
  • Findings of reduced smooth pursuit velocity, hypometric saccades, and increased trial-to-trial variability of saccade amplitude implicate vermal dysfunction in AD.

  • Takarae et al. (2004) found the ASD group had increased variability in saccade accuracy, together with mild saccadic hypometria in those without delayed language development.

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.
