Abstract

Autism spectrum disorders are characterised by severe deficits in socialisation, communication, and repetitive or unusual behaviours. Increases over time in the frequency of these disorders (to present rates of about 60 cases per 10,000 children) might be attributable to factors such as new administrative classifications, policy and practice changes, and increased awareness. Surveillance and screening strategies for early identification could enable early treatment and improved outcomes. Autism spectrum disorders are highly genetic and multifactorial, with many risk factors acting together. Genes that affect synaptic maturation are implicated, resulting in neurobiological theories focusing on connectivity and neural effects of gene expression. Several treatments might address core and comorbid symptoms. However, not all treatments have been adequately studied. Improved strategies for early identification with phenotypic characteristics and biological markers (eg, electrophysiological changes) might hopefully improve effectiveness of treatment. Further knowledge about early identification, neurobiology of autism, effective treatments, and the effect of this disorder on families is needed.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Biological abnormalities have been reported in eye tracking, neuroanatomical pathway connectivity, brain regional volumes, cortical activation during social and communication tasks, serotonin levels, and other biological assays, but not with sufficient consistency to constitute uniform diagnostic biomarkers.

    “Biological abnormalities have been reported in eye tracking, neuroanatomical pathway connectivity, brain regional volumes, cortical activation during social and communication tasks as measured with functional magnetic resonance imaging and magnetoencephalography, serotonin levels, and other biological assays, but not with sufficient consistency for these to constitute uniform diagnostic biomarkers”
  • Co-morbid traits such as depression, anxiety, or inattention/hyperactivity are often associated with ASD and affect general reward processing and intervention response.

    “co-morbid traits, such as depression, anxiety, or inattention/hyperactivity, are often associated with ASD [212], and are known to affect general reward processing [213,214] and intervention response [215].”

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.
