Autism & sleep problems: Effects

This is part 3 of a 4-part series on autism and sleep problems

Autism & sleep problems: Solutions


Research shows that sleep problems worsen autism symptoms across most core domains[1]The relationship between sleep and behavior in autism spectrum disorder (ASD): a review—particularly in the social domain[2]Sleep problems as possible predictors of intensified symptoms of autism—and were the highest predictor of challenging behaviors in autism.[3]Sleep, anxiety and challenging behaviour in children with intellectual disability and/or autism spectrum disorder


Correlations with dysfunctions

Autistic children without intellectual disability (i.e. high-functioning autism) experience more sleep-related anxiety, night waking, parasomnias, sleep-disordered breathing, and daytime sleepiness than neurotypicals.[4]Sleep and Executive Functioning Among High-IQ School-Aged Children with Autism

Certain sleep problems were found to correlate with certain dysfunctions:[5]Sleep and Executive Functioning Among High-IQ School-Aged Children with Autism

  • Sleep duration and resistance to falling asleep correlated with behavioral regulation and executive dysfunction.
  • The ability to fall asleep quickly correlated with working memory.
  • The ability to remain asleep through the night correlated with accuracy and efficiency of inhibiting conflicting information.

Sleep disorders

A study from 2015 that investigated the correlation between sleep disorders and the behavior of autistic people found correlations between sleep disorders and thinking- and behavioral problems:[6]Influence of sleep disorders on the behavior of individuals with autism spectrum disorder

  • Disorders of arousal (sleepwalking, sleep terrors, and confusional arousals) were correlated with thinking problems.
  • Disorders of excessive somnolence (i.e. desire to sleep) were correlated with thinking and behavioral problems.

The high frequency of sleep disorders was found to correlate with some of the behavioral traits that autistic people already exhibit (see below).[7]Influence of sleep disorders on the behavior of individuals with autism spectrum disorder


Behavioral traits

The behavioral profiles of autistic people were characterized by behavioral problems such as social anxiety & depression; withdrawal; and somatic, thought, attention, delinquency, aggression, internalizing, and externalizing.

In the diagram below you can see how autistic people compare to neurotypicals on these behavioral problems.[8]Influence of sleep disorders on the behavior of individuals with autism spectrum disorder

So it’s these areas that are likely predominantly affected by sleep problems. Speaking from personal experience, my aggression and volatility, as well as my anxiety certainly go up, whereas cognitive functions decrease.


Sleep & challenging behaviors

Studies exploring the relationship between sleep and challenging behaviors in autism found:[9]The relationship between sleep and behavior in autism spectrum disorder (ASD): a review
