“There’s a lot of evidence that we need to pay more attention” to sleep in seniors, she said.Īnimal studies give clues to the biology behind these changes. She recommended that people at risk of Alzheimer’s be screened for sleep disorders, especially apnea, which has effective treatment. Sleep apnea - brief interruptions of breathing that repeatedly awaken people without them realizing - caused a nearly two-fold increase in that risk, Yaffe said. Kristine Yaffe of the University of California, San Francisco. What’s the risk over time? Two sleep studies tracked nearly 6,000 people over five years, and found those who had poor sleep quality - they tossed and turned and had a hard time falling asleep - were more likely to develop mild cognitive impairment, early memory problems that sometimes lead to Alzheimer’s, said Dr. Their memories weren’t transferred properly from the brain’s short-term memory bank into longer-term storage. The more amyloid people harboured in a particular brain region, the less deep sleep they got - and the more they forgot overnight, Walker said. They were given words to memorize, and their brain waves were measured as they slept overnight. Walker’s team gave PET scans to 26 cognitively healthy volunteers in their 70s to measure build-up of that gunky amyloid. New research suggests poor sleep may increase people’s risk of Alzheimer’s disease. Miroslaw Mackiewicz of the National Institute on Aging, who wasn’t part of the new work.
