Attention lapses due to sleep deprivation due to flushing fluid from brain

What I want to know is: can we trigger these flushes? My grandfather died of/with Alzheimer’s, and I’d prefer not to follow in his footsteps. If we determine that these flushes are key to good brain health, and there were a way either through a pill or even a treatment to up the frequency of these flushes, that would be awesome.
