Background: Sleep concerns are common in children with autism spectrum disorders (ASD). The impact of poor sleep on cognitive performance in ASD children is not well-established. We investigated the possible correlation between sleep quality in ASD children and cognitive performance. The Cambridge Neuropsychological Test Automated Battery (CANTAB) was administered to examine specific components of non-verbal cognition. Methods: The Children’s Sleep Habits Questionnaire (CSHQ) and actigraphy-measured data from 18 children with diagnosis of ASD were evaluated. Motor planning task (MOT), simple reaction time task (SRT) and the intradimensional/extradimensional shift (IED) of CANTAB were administered. Results: ASD good sleeper (ASD-GS) showed significant better response time for SRT task as compared to ASD poor sleeper (ASD-PS) based on CSHQ score. Parameters of bedtime resistance (r = 0.531, p = 0.023), sleep anxiety (r = 0.474, p = 0.047) from CSHQ and actigrapgy dependent (wake after sleep onset (WASO) (r = 0.430, p = 0.024) were significantly correlate with response time of SRT task. Conclusion: We conclude that some signs reflecting the presence of poor sleep in ASD correlate with various aspects of motor output on non-verbal performance tasks. The question is raised whether poor sleep in non-complaining persons with autism should be treated.
IntroductionADHD is one of the most common neuropsychiatric disorders in children. The worldwide prevalence is estimated to be between 2–18%. The exact cause of ADHD is still unknown, but some factors have been found to increase the risk of having ADHD like increase TV exposure time and video games.ObjectivesTo study the association between time spent on computer tablets (iPads or Android tablets) by children and ADHD.MethodsThis cross sectional study targeted children from 3 to 12 years old who use computer tablets. Two non-random sampling techniques were used to distribute self-administered questionnaires to one of the caregivers of 275 children, 36 of them installed an application in their children's computer tablets that measures the actual time spent by the children. The questionnaire contains demographics, validated Arabic ADHD rating scale and questions to assess the parental attitude. The SPSS package was used for statistical analysis.ResultsThe results showed that the overall prevalence of ADHD is 22.2% and it is higher in males. There is no statistically significant association between ADHD and all variables except for the time spent on computer tablets, which showed that children using computer tablets more than the average time have an increased chance of having ADHD with an odds ratio of 1.9 with 95% confidence interval from 1.08 to 3.40.ConclusionThis study shows an association between time spent on computer tablets by children and ADHD. There is need for longitudinal studies to demonstrate the temporality and to confirm the association.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
