APOE ε4 allele, cognitive dysfunction, and obstructive sleep apnea in children

APOE epsilon4 allele is more frequent in children with obstructive sleep apnea and particularly in those who develop neurocognitive deficits, suggesting that the APOE epsilon4 allele is associated with not only increased odds of having sleep-disordered breathing, but also with an increased risk for neurocognitive dysfunction.
