"Children with sleep apnea have higher [blood pressure] compared to children with snoring. This may explain why, paradoxically, we find higher oxygen levels in children with [obstructive sleep apnea]."
"By taking into account the role of blood pressure in regulating the amount of oxygen concentration in the brain, we might have a better understanding of the relationship between sleep-disordered breathing and cognitive deficit," said Amin, who added that this research may prove important in future prevention and treatment efforts.
The study was published in the first issue for November of the American Journal of Respiratory and Critical Care Medicine.

The findings point to a new area of study, agreed Dr. David Gozal, a professor of pediatrics and director of the Kosair Children's Hospital Research Institute at the University of Louisville, who wrote an accompanying editorial.
"[The study] shows us that what is happening in children with OSA and that neurocognitive deficits are not just in the brain matter but involve the cardiovascular system as well," Gozal said.
