Can Sleeping Too Long Cause Dementia?
Here’s an interesting study that supports my explanation for how untreated sleep apnea can cause or aggravate Alzheimer’s. In this month’s issue of the European Journal of Neurology, researchers from Spain followed over 3000 volunteers for about 3 years on average, and found that people who reported sleep duration longer than 9 hours had over 2x the risk of developing dementia. They found increased risks as well for short sleepers (< 5 hours), but after adjusting for other factors, the risks was only slightly raised.
