A brand new research finds older adults who obtained constructive airway stress remedy prescribed for obstructive sleep apnea may be much less prone to develop Alzheimer’s illness and other forms of dementia.

Researchers from Michigan Medicine’s Sleep Disorders Centers analyzed Medicare claims of greater than 50,000 Medicare beneficiaries ages 65 and older who had been identified with OSA. In this nationally consultant research, they examined if these individuals who used constructive stress remedy have been much less prone to obtain a brand new prognosis of dementia or over the subsequent 3 years, in comparison with individuals who didn’t use constructive airway stress.

“We found a significant association between positive airway pressure use and lower risk of Alzheimer’s and other types of dementia over three years, suggesting that positive airway pressure may be protective against dementia risk in people with OSA,” says lead writer Galit Levi Dunietz, Ph.D., M.P.H., an assistant professor of neurology and a sleep epidemiologist.

The findings stress the affect of sleep on cognitive perform. “If a causal pathway exists between OSA treatment and dementia risk, as our findings suggest, diagnosis and effective treatment of OSA could play a key role in the cognitive health of older adults,” says research principal investigator Tiffany J. Braley, M.D., M.S., an affiliate professor of neurology.

Obstructive sleep apnea is a situation during which the higher airway collapses repeatedly all through the night time, stopping regular respiratory throughout sleep. OSA is related to quite a lot of different neurological and cardiovascular situations, and lots of are at excessive risk for OSA.

And can also be prevalent, with roughly 5.8 million Americans presently dwelling with it, Braley says.
