Study Identifies 3 Factors to Potentially Delay Dementia for 13 Years
Researchers found that normal blood pressure, no diabetes and not smoking were linked to nearly 13 more dementia-free years.
- On August 5, 2026, researchers published findings in Neurology Open Access linking midlife vascular health—specifically blood pressure, diabetes, and smoking—to dementia onset timing and dementia-free lifespans.
- Data from the ARIC study, tracking 12,409 adults for 26 years, found that avoiding type 2 diabetes, high blood pressure, and smoking can delay dementia onset by about 13 years.
- "Our findings argue that people need to actively avert these factors in midlife as a strategy for preserving brain health for more than a decade," said Dr. Josef Coresh, director of the Optimal Aging Institute at NYU Langone.
- Research identified health disparities: women remained dementia-free longer than men, while White participants lived 19.6 years without dementia compared to 16 years for Black participants.
- Vascular health is crucial for preserving brain function, as damage to blood vessels reduces oxygen delivery to the brain, underscoring the importance of managing these risk factors during middle age.
