Treatable sleep disorder common in people with thinking and memory problems: Study
MINNEAPOLIS - Obstructive sleep apnea is when breathing is repeatedly interrupted during sleep. Research has shown people with this sleep disorder have an increased risk of developing cognitive impairment and Alzheimer's disease. Yet, it is treatable. A preliminary study released today, February 28, 2021, has found that obstructive sleep apnea is common in people with cognitive impairment. The study will be presented at the American Academy of Neurology's 73rd Annual Meeting being held virtually April 17 to 22, 2021.
Cognitive impairment includes memory and thinking problems that affect concentration, decision making and learning new things. The risk of cognitive impairment increases as people age.
"Better sleep is beneficial to the brain and can improve cognitive skills. Yet in our study, we found that over half of the people with cognitive impairment had obstructive sleep apnea," said study author Mark I. Boulos, M.D., of the University of Toronto in Canada and member of the American Academy of Neurology. "We also found that those with the sleep disorder had lower scores on thinking and memory tests. Fully understanding how obstructive sleep apnea affects this population is important because with treatment, there is potential to improve thinking and memory skills as well as overall quality of life."
