Alzheimer's is not about dehydration - it happens because of accumulation of "plaques" between nerve cells. There are various theories about why this happens, and the most popular one is that the processes that are responsible for preventing the accumulation break down somehow.
There are things that are correlated with not getting alzheimers - regular exercise, and regular mental activity both show up. I'm not aware of any that say anything about dehydration.
So, basically, I think this is at best, pseudo-science.
