Increasing Risk Of Dementia

People who sleep for more than nine hours a day are increasing their risk of dementia, according to a study. Research has discovered that those who sleep the longest could be twice as likely to develop memory loss, dementia and Alzheimer’s disease in old age. The study, published last week in the European Journal of Neurology, found that even once the results were adjusted for smoking and drinking habits, age and level of education, those who reported sleeping and napping for more than nine hours every day were 2.18 times more likely to end up with a degenerative condition. People who got the least amount of sleep – categorized as less than five hours a night – could also expect a slightly increased risk. However, the neurologists said sleeping longer may be an early symptom of undiagnosed dementia.
