It's great to see more investment into this disease.
When my grandma fought Alzheimer's over the span of a decade it was very striking to see that the effect of a lack of hydration and the disease itself kind of overlapped. When she had a particularly bad day we used to give her a saline IV and you could immediately notice how she cleared up and regained her brain powers after each IV.
I'm not up to date on current research into that direction, but I think hydration plays a very big role in Alzeimer's symptoms on the elderly.
I know it sounds ridiculous, but once I'm rich enough I want to build an elderly care center/hospital with urine-based hydration monitoring for each participant so family members can be sure that their loved ones have a healthy water intake each and every day.
