Book 03 / Brain health & prevention

Outrunning Alzheimer’s

Mark A. Smith

The expanded edition: reporting from public Rapamycin News discussions, refreshed through October 2026 and checked against scientific literature and trial records — including the semaglutide EVOKE trials, blood-pressure prevention evidence, and the arrival of the anti-amyloid antibodies. Evidence is graded by kind, with intervention dossiers, biomarker worksheets, and a watch list rather than a treatment protocol.

  • The evidence lanes & grades
  • What the trials now say
  • Dossiers, biomarkers & worksheets

Read with context

A library, not a treatment protocol.

These books are works of reporting, education, and scientific interpretation—not medical advice. They do not establish that rapamycin extends human lifespan or that any intervention reliably prevents Alzheimer’s disease. Discuss individual treatment decisions with a qualified clinician; trial results and regulatory status can change.
