When we think about The Retired Life, a pretty common theme. But now that bubble has burst 바카라 게임 웹사이트 and we're going to be keeping a closer eye on how much time we spend in dreamland, too: Consistently sleeping more than nine hours a night is linked to an increased , according to new research published in Neurology.
For their , researchers at the Boston University School of Medicine analyzed data collected from 2,457 adults enrolled in the Framingham Heart Study. Men and women were asked how many hours of sleep they typically get each night, and then were observed for 10 years to .
The researchers ultimately found that participants who each night were six times more likely to develop dementia than those participants who slept for less than nine hours a night. Participants who slept longer were also found to have smaller brain volumes.
But don't start regulating bedtimes just yet: "We're not suggesting you go wake up Grandpa," Sudha Seshadri, MD, senior study author and professor of neurology at Boston University School of Medicine, . "We think this might be a marker for the risk of dementia, not a cause."
If that's the case and oversleeping is actually a symptom and , it could help doctors detect in patients and make faster diagnoses.
But why would dementia cause people to sleep more? Dr. Seshadri can't say for sure, but he hypothesizes that prolonged sleep might be the brain's way of trying to remove the , which are associated with Alzheimer's.
