Sleep in Autism Spectrum Disorder: The trajectory and impact on daytime functioning


Sleep problems are a major concern for individuals with Autism Spectrum Disorder (ASD) and their families, with 50%–80% of those diagnosed reporting some form of sleep disturbance. My research is assessing how sleep changes over time in children with ASD. There is emerging evidence that sleep problems are more persistent across the lifespan for those with ASD than for their neurotypical peers who tend to grow out of sleep problems. We are also exploring the relationship between sleep, cognition and behaviour in ASD. Sleep problems in ASD have been linked to reduced verbal and nonverbal skills, lower school outcomes and behavioural disturbance. However, it is unclear if deficits in cognition and increased disruptive behaviours may be explained by the impact that poor sleep has on executive functioning skills.

Why my research is important

Developing a better understanding of the trajectory and impact of poor sleep in children with ASD can help to inform future interventions for sleep in this population.
