45% OF DEMENTIA CASES ARE PREVENTABLE. 5 WARNING signs you can’t ignore

45% of all dementia cases are not written into your DNA — that is not an estimate, it is the conclusion of the 2024 Lancet Commission report, the largest dementia review of the decade. Nearly half of every diagnosis that will be made twenty years from now does not have to happen. The window to act is open right now, today, and almost nobody is using it. Most people whose brains are already beginning to change have no idea it is happening. The five warning signs are quiet, measurable, and almost always blamed on age — when they shouldn't be. This video walks through all five warning signs Dr. Thomas Grant sees most often in his patients over sixty — how each one works inside the body, what the research actually shows, and what to ask your doctor about this month. Covered in full: untreated hearing loss raising dementia risk by 50%, cataract surgery cutting it by 29%, sarcopenia and the 2025 study linking muscle loss directly to cognitive decline, the glymphatic system and why broken sleep lets beta amyloid and tau pile up in brain tissue, visceral fat driving the insulin resistance some researchers now call "brain diabetes," plus the gum-disease connection most family doctors still miss. The evidence is clear — the earlier these signs are addressed, the stronger the protection. Three specific tests to request at your next appointment (an audiogram, a fasting lipid panel with LDL broken out, and hemoglobin A1c), the free SAGE self-assessment developed at Ohio State, the truth about why "slowing down" in your seventies is the opposite of what protects the brain — all of it is here, explained plainly.
