Molecular hydrogen bonding appears to have a medically-interesting effect on cell permeability in the brain, and I'm sure other things. But most hydrogen bond effects are pretty short-lived, while amyloid plaques build up over a long time as the brain fails to remove them as waste. This is obviously hugely preliminary, but it sounds possible that whatever disruption is being caused is at least shorter-term or less destructive than the benefits of counteracting a slow-moving process like Alzheimer's.
