Sleep Disturbances Increase the Impact of Working Memory Deficits on Learning Problems in Adolescents with High-Functioning Autism Spectrum Disorder.

Bellon-Harn et al. (2020) asked teens with high-functioning autism to fill out three short surveys. One asked about sleep trouble. One tested working memory. One asked about school learning problems.

The team then used statistics to see if bad sleep made the link between weak working memory and school problems even stronger.

Teens who slept poorly showed a bigger gap between low working-memory scores and learning problems.

In plain words, bad sleep turned small memory slips into big homework headaches.

Lai et al. (2017) pooled many earlier studies and found that kids with HF-ASD already score half a step below peers on most memory tests. L et al. add the new point that sleep loss widens that gap.

Rosa et al. (2017) showed weaker working memory predicts lower daily living skills in the same age group. L et al. move the story forward by naming sleep as a dial that turns that link up or down.

Gandhi et al. (2022) later tried a short computer memory-training game and saw gains. Their pilot hints that fixing sleep first (L et al.) could make such training work even better.

You now have a quick rule: if an HF-ASD teen struggles to learn, check sleep before you write a new goal. A five-item sleep screener plus parent log may save weeks of extra tutoring.
