Alzheimer's disease affects millions of Americans, and the numbers are expected to grow. New research suggests there may be a link between prolonged sleep and the risk of dementia.

New research suggests those who sleep for more than 9 hours each night are at a higher risk of developing dementia.

Over 46 million people are living with dementia worldwide, and the number is expected to almost triple by 2050.

This is pretty much the opposite of what I read elsewhere. That article said not sleeping a full 8 hours a night would lead to Alzheimers.

Maybe it's just like "climate change" and can't be affected by human activity, no matter how hard we try.
