LOCKLEY, Auteur Année de publication : 2018 Article en page(s) : p.391-403 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Increased severity of problematic daytime behavior has been associated with poorer sleep quality in individuals with autism spectrum disorder. In this work, we investigate whether this relationship holds in a real‐time setting, such that an individual's prior sleep can be used to predict their subsequent daytime behavior. We analyzed an extensive real‐world dataset containing over 20,000 nightly sleep observations matched to subsequent challenging daytime behaviors (aggression, self‐injury, tantrums, property destruction and a challenging behavior index) across 67 individuals with low‐functioning autism living in two U.S. residential facilities. Using support vector machine classifiers, a statistically significant predictive relationship was found in 81% of individuals studied (P < 0.05). For all five behaviors examined, prediction accuracy increased up to approximately eight nights of prior sleep used to make the prediction, indicating that the behavioral effects of sleep may manifest on extended timescales. Accurate prediction was most strongly driven by sleep variability measures, highlighting the importance of regular sleep patterns. Our findings constitute an initial step towards the development of a real‐time monitoring tool to pre‐empt behavioral episodes and guide prophylactic treatment for individuals with autism. Autism Res 2018, 11: 391–403. © 2017 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary We analyzed over 20,000 nights of sleep from 67 individuals with autism to investigate whether daytime behaviors can be predicted from prior sleep patterns. Better‐than‐chance accuracy was obtained for 81% of individuals, with measures of night‐to‐night variation in sleep timing and duration most relevant for accurate prediction. Our results highlight the importance of regular sleep patterns for better daytime functioning and represent a step toward the development of ‘smart sleep technologies' to pre‐empt behavior in individuals with autism.

The developmental trajectory of parent-report and objective sleep profiles in autism spectrum disorder: Associations with anxiety and bedtime routines / Fay E. FLETCHER in Autism, 21-4 (May 2017)  

Public ISBD [article]  inAutism > 21-4 (May 2017) . - p.493-503 Titre : The developmental trajectory of parent-report and objective sleep profiles in autism spectrum disorder: Associations with anxiety and bedtime routines Type de document : texte imprimé Auteurs : Fay E. FLETCHER, Auteur ; Mistral D FOSTER-OWENS, Auteur ; Russell CONDUIT, Auteur ; Nicole J. RINEHART, Auteur ; Deborah M. RIBY, Auteur ; Kim CORNISH, Auteur Article en page(s) : p.493-503 Langues : Anglais (eng) Mots-clés : actigraphy  anxiety  autism spectrum disorder  bedtime routines  school-age children  sleep problems Index. décimale : PER Périodiques Résumé : The present study compared the course of parent-report and actigraphy-derived sleep profiles over a 1-year period, in school-age children with autism spectrum disorder and typically developing children. The Children’s Sleep Habits Questionnaire and 14 nights of actigraphy were used to assess sleep profiles. Parents also completed the Spence Children’s Anxiety Scale, the Social Worries Questionnaire and the Bedtime Routines Questionnaire. Between-group differences in parent-reported sleep problems were less pronounced at follow-up compared to baseline. The course of objective sleep was comparable between groups, with a significant reduction in sleep duration over time in both groups. Children with autism spectrum disorder were further characterised by significantly more night-to-night variability in sleep quality, across both time points. Reductions over time in parent-reported sleep problems were significantly associated with reduced anxiety. Reductions in actigraphy-derived sleep efficiency were associated with an increased frequency of maladaptive activities in the hour before bedtime, in both children with and without autism spectrum disorder.

The relationship between sleep and behavior in autism spectrum disorder (ASD): a review / Simonne COHEN in Journal of Neurodevelopmental Disorders, 6-1 (December 2014)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 6-1 (December 2014) . - p.44 Titre : The relationship between sleep and behavior in autism spectrum disorder (ASD): a review Type de document : texte imprimé Auteurs : Simonne COHEN, Auteur ; Russell CONDUIT, Auteur ; Steven W. LOCKLEY, Auteur ; Shantha M.W. RAJARATNAM, Auteur ; Kim CORNISH, Auteur Article en page(s) : p.44 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Low-functioning autism  Sleep difficulties in ASD  Treating sleep in ASD Index. décimale : PER Périodiques Résumé : Although there is evidence that significant sleep problems are common in children with autism spectrum disorder (ASD) and that poor sleep exacerbates problematic daytime behavior, such relationships have received very little attention in both research and clinical practice. Treatment guidelines to help manage challenging behaviors in ASD fail to mention sleep at all, or they present a very limited account. Moreover, limited attention is given to children with low-functioning autism, those individuals who often experience the most severe sleep disruption and behavioral problems. This paper describes the nature of sleep difficulties in ASD and highlights the complexities of sleep disruption in individuals with low-functioning autism. It is proposed that profiling ASD children based on the nature of their sleep disruption might help to understand symptom and behavioral profiles (or vice versa) and therefore lead to better-targeted interventions. This paper concludes with a discussion of the limitations of current knowledge and proposes areas that are important for future research. Treating disordered sleep in ASD has great potential to improve daytime behavior and family functioning in this vulnerable population.
