Abstract

BACKGROUND: Social impairments are central to the syndrome of autism. The neuropeptide oxytocin (OT) has been implicated in the regulation of social behavior in animals but has not yet been examined in autistic subjects. METHODS: To determine whether autistic children have abnormalities in OT, midday plasma samples from 29 autistic and 30 age-matched normal children, all prepubertal, were analyzed by radioimmunoassay for levels of OT. RESULTS: Despite individual variability and overlapping group distributions, the autistic group had significantly lower plasma OT levels than the normal group. OT increased with age in the normal but not the autistic children. Elevated OT was associated with higher scores on social and developmental measures for the normal children, but was associated with lower scores for the autistic children. These relationships were strongest in a subset of autistic children identified as aloof. CONCLUSIONS: Although making inferences to central OT functioning from peripheral measurement is difficult, the data suggest that OT abnormalities may exist in autism, and that more direct investigation of central nervous system OT function is warranted.

  • Innocuous somatosensory stimulation such as touch, warm temperature, vibration, and electroacupuncture increase oxytocin levels in plasma and cerebrospinal fluid.

    “Innocuous somatosensory stimulation such as touch, warm temperature, vibration, and electroacupuncture increase oxytocin levels in plasma and cerebrospinal fluid [91, 92].”
  • Lower levels of plasma oxytocin have been reported in populations with ASD.

    “Lower levels of plasma oxytocin [185] and abnormal serotonin concentrations in the brain and tissues outside the blood-brain barrier have been reported in populations with ASD [186,187].”

    From Vitamin D and Autism Spectrum Disorder: A Literature Review (2016) · cites this paper as [185]

  • Plasma levels of OT vary with autism spectrum disorder, parenting styles, and major depression.

    “For example, plasma levels of OT appear to vary with autism spectrum disorder (Modahl et al., 1998), parenting styles (Feldman et al., 2007;Gordon et al., 2010) and major depression (Parker et al., 2010).”
  • OT plasma concentration is significantly lower in patients with ASD than in healthy subjects.

    “Studies in our lab and others have found that OT plasma concentration is significantly lower in patients with ASD than in healthy subjects (Andari et al. 2010; Modahl et al. 1998).”

    From A precision medicine approach to oxytocin trials (2017) · cites this paper as Modahl et al. 1998

  • A subgroup of ASD affected children appeared to have lower plasma OT levels.

    “A subgroup of ASD affected children also appeared to have lower plasma OT levels (Modahl et al., 1998).”

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.
