Prolonged Sleep May Predict Future Risk of Dementia, Study Shows
Sleeping for more than nine hours each night may predict the risk of developing dementia, and people who sleep a lot tend to have smaller brains. Those are among the findings in a new study, “Prolonged sleep duration as a marker of early neurodegeneration predicting incident dementia," that appeared recently in the journal Neurology. Evidence from past studies have hinted at associations between both long and short sleep duration and an increased risk of dementia. However, it remains unclear if sleep duration is a risk factor or a marker for dementia. Sleep may provide a restorative fu

This could explain why sleeping longer periods of time is associated with higher Alzheimer’s rates. It could be a causal connection, related to sleep position. Head elevation may help.

      Thank you for that info and your research in this field. While this is all still preliminary it does shed a little bit of light on Alzheimer’s.
