That’s unclear yet. It’s not obvious how to revert brain cells without losing important information, which is a potential way this treatment could fail. Hopefully there’s a way to do it, or else the brain can survive getting turned into stem cells by parts, but that’s a clear obstacle.
My guess is that rejuvenation of the rest of the body [esp kidney/liver] will maybe give the brain an extra 2 decades [but this is an imprecise estimate]. 8 years is an important number in longevity b/c it corresponds to “mortality rate doubling time”.
What about in neurons/post-mitotic brain cells?
