Brain imaging showed that in older adults taking memory tests, more years of education were associated with more active frontal lobes – the opposite of what happened in young adults. It appears possible that education strengthens the ability to "call in the reserves" of mental prowess found in that part of the brain. "It 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." More than anything, the study opens up avenues of inquiry for investigating the perplexing link between SDB and cognitive deficits in children. Understanding the source of that association will be key in future efforts to treat or prevent it.
