An Investigation of Sleep Characteristics, EEG Abnormalities and Epilepsy in Developmentally Regressed and Non-regressed Children with Autism
Abstract
This study investigated sleep of children with autism and developmental regression and the possible relationship with epilepsy and epileptiform abnormalities. Participants were 104 children with autism (70 non-regressed, 34 regressed) and 162 typically developing children (TD). Results suggested that the regressed group had higher incidence of circadian rhythm disorders than non-regressed children. The regressed group showed higher Children's Sleep Habits Questionnaire Bedtime Resistance, Sleep Onset Delay, Sleep Duration and Night-Wakings scores. Epilepsy and frequent epileptiform EEG abnormalities were more frequent in regressed children. Past sleep disorders and a history of developmental regression were significantly associated with sleep disorders. This study is an initial step in better understanding sleep problems in regressed children with autism, further studies are necessary to better investigate these aspects.

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.
