grip strength predicts all-cause mortality and dementia risk
In plain terms: Does hand-grip strength predict death and dementia?
Part of: • Cardiorespiratory Fitness & Strength
Yes — grip strength is a robust, reproducible predictor of mortality and dementia risk, but it is a low-cost proxy/marker of overall health, not a proven causal lever you can train to change outcomes.

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
Educational only, not medical advice. Grades and scores reflect published evidence weighted by study design and quality; see the methodology.
