Does Cognitive Health actually make a difference, or is it overhyped?

This topic has unusually strong randomized-trial evidence for a behavioral field: the landmark FINGER trial (Lancet, 2015) showed a 2-year multidomain intervention combining diet, exercise, cognitive training and vascular risk management improved cognitive function in at-risk older adults, with benefit holding regardless of baseline characteristics, and this has now been extended by the large US POINTER randomized trial (JAMA, 2025) comparing structured and self-guided versions of the same approach. Weighing the data: Cognitive Health looks well-supported and consequential — the evidence is rated strong (87/100) and its estimated impact on longevity is also rated highly (81/100), making it one of the more solidly-backed choices on Vitaebase.
