A generic HIV drug shows promise for reducing age-related inflammation in mice. Could it treat Alzheimer's disease?

"...this study shows that sleep disruption causes the damaging protein tau to increase rapidly and to spread over time."

The test could one day also detect other neurodegenerative conditions such as multiple sclerosis, traumatic brain injury, or stroke.

Daytime napping alone is significantly associated with high levels of tau, a sign of Alzheimer’s disease.

"Without a complete understanding of the illness, we're not going to be able to develop therapies that work for all people."

And the number of people living with dementia could more than double again by 2050, researchers say.

When proteins don't fold into the right shape, they don't work right. New research digs into how cells decide to save or scrap the misfolded proteins.
