Hypertension's underestimated role in dementia

Our recalculations of current evidence suggest that hypertension's role in dementia could be eight times higher than previous estimates when accounting for the role of stroke, underscoring the urgent need for enhanced global prevention strategies. Hypertension's high lifetime risk, widespread prevalence, frequent underdiagnosis, and inadequate management offer the single greatest opportunity for delaying, allaying, or preventing stroke, heart disease, and dementia.
