Rudy Tanzi says he may be nearing a cheap, safe Alzheimer’s prevention pill

Rudolph Tanzi has spent decades pursuing a way to stop Alzheimer’s disease before it starts. As a leading researcher, he has long spoken about the need for a simple, widely accessible solution.

Tanzi’s vision is a tiny white pill that would be inexpensive and safe enough to be added to everyday water supplies. He has described it as a public‑health tool that could reach anyone, regardless of income.

Recent indications suggest he believes the science is finally aligning with that goal, hinting that a breakthrough may be on the horizon.
