Sleep quality affects cognitive performance of autistic, NT

Sleep quality influences cognitive performance of autistic, neurotypical children

One night of poor sleep significantly decreases performance on intelligence tests in children with autism spectrum disorder (ASD) and also in neurotypical children (without ASD). This is the conclusion made by researchers at the Hôpital Rivière-des-Prairies, affiliated with the Institut universitaire en santé mentale de Montréal and Université de Montréal.

For a paper published in the International Journal of Psychophysiology, the researchers observed the EEG measures of 13 autistic children and 13 neurotypical children (children with a mean age of 10 years old without an intellectual deficiency or sleep problem and who were not on medication) and found that disruptions in protective brain waves during sleep are associated with lower results on verbal IQ tests.

The brain waves demonstrating good sleep consolidation in these children were measured in a laboratory. These markers of light sleep known as "sleep spindles" occur during a sleep phase that repeats throughout the night in which body metabolism slows and the brain rests (contrary to rapid eye movement sleep, when the brain is active and dreams).
