About two-thirds of children with sleep-disordered breathing (SDB) — snoring or obstructive sleep apnea (OSA) — have some degree of cognitive deficit, but the severity of the cognitive deficit has been notoriously difficult to correlate to the severity of the sleep-disordered breathing, suggesting that other important issues may be at play, or that the right factors were simply not being measured.
A study published in the American Journal of Respiratory and Critical Care Medicine opens the door to understanding the complex relationship between sleep, breathing and brain function in a whole new way.
