Therefore, this study investigated how sleep problems are associated with…

Children with autism spectrum disorder are often reported to have more sleep deficits and poorer sleep quality compared with children with typical development. However, most previous studies have serious methodological limitations, such as varying sample sizes in the comparison groups, wide age range of participants, and body mass index not…

Hahn, Michael; Joechner, Ann-Kathrin; Roell, Judith; Schabus, Manuel; Heib, Dominik P. J.; Gruber, Georg; Peigneux, Philippe; Hoedlmoser, Kerstin – Developmental Science, 2019
Sleep spindles are related to sleep-dependent memory consolidation and general cognitive abilities. However, they undergo drastic maturational changes during adolescence. Here we used a longitudinal approach (across 7 years) to explore whether developmental changes in sleep spindle density can explain individual differences in sleep-dependent…

Tse, Choi Yeung Andy; Lee, Hong Paul; Chan, Ka Shing Kevin; Edgar, Veronica Bordes; Wilkinson-Smith, Alison; Lai, Wing Him Elvis – Autism: The International Journal of Research and Practice, 2019
Sleep disturbance and executive dysfunction have been widely reported in children with autism spectrum disorder. While the positive impacts of physical activity on sleep quality and cognition are documented in children with typical development, similar studies in children with autism spectrum disorder are scarce. The objective of this study was to…

Intellectual abilities were assessed by the Wechsler Intelligence Scale for Children (4th edition) and sleep variables by questionnaires, actigraphy, and sleep diaries. Correlation…
