Less Sleep in Middle Age May Intensify Dementia Risk, Study Finds
The research, trailing thousands of people from age 50 on, believes those who sleep six hours or less a night are more likely to develop dementia in their late 70s.
Could getting too little sleep increase your chances of developing dementia?
For years, scientists have contemplated this and other queries about how sleep relates to cognitive decline. Answers have been vague because it is hard to know if insufficient sleep is a symptom of the brain changes that inspire dementia — or if it can actually help cause those changes.
Now, a large new study reports some of the most cogent findings yet to suggest that people who don’t get sufficient sleep in their 50s and 60s may be more likely to develop dementia when they are older.
The research, published Tuesday in the journal Nature Communications, has restrictions but also several strengths. It surveyed nearly 8,000 people for about 25 years, beginning when they were 50 years old. It found that those who regularly reported sleeping six hours or less on an average weeknight were about 30 percent more likely than people who regularly got seven hours sleep (defined as “normal” sleep in the study) to be diagnosed with dementia approximately three decades later.
To avoid this, it could be part of our plans as we get old to have enough sleep to avoid this health related issues older people go thought as a result of circumstances we could control.
Have a blessed weekend.
