@MarkFreedom Interesting. Thanks for sharing!
OK: don't overdo it on protein intake. On it. 
For anyone wanting a quick overview, here's a snippet from the Newsweek article:
"An experimental treatment completely reversed Alzheimer’s disease in mice by reducing the levels of a single enzyme in the animals' brains. The results further bolster the theory that amyloid plaques are at the root of this mysterious brain disease, and that addressing these plaques could lead to an eventual cure for Alzheimer's.
The study, published February 14 in the Journal of Experimental Medicine, found that slowly reducing levels of the enzyme BACE1 in mice as they aged either prevented or reversed the formation of amyloid plaques in the brain, a hallmark sign of Alzheimer’s disease.

Amyloid plaques, formed when bits of protein clump together in the brain, are found in high amounts in Alzheimer’s patients. BACE1 is a protein that naturally forms in the brain and helps produce beta-amyloid peptide, a protein also involved with brain plaque formation."
