A NYU longitudinal study of 12,409 adults found that the absence of three midlife vascular risk factors—high blood pressure, type‑2 diabetes and smoking—was associated with about 13 extra years of dementia‑free life compared with participants who had all three. The research highlighted a more than two‑fold increase in dementia risk for those with all three factors and noted demographic differences in dementia‑free longevity. A follow‑up analysis of the same ARIC cohort confirmed these results. Over an average 26‑year follow‑up of participants (mean age 56), 3,008 developed dementia while 5,238 died without it. Those without any of the three risk factors remained dementia‑free for roughly 30 years, versus about 17.5 years for those with all three—a gap of nearly 13 years. Having all three risk factors more than doubled dementia risk (hazard ratio ≈ 2.7) and increased non‑dementia mortality by over fivefold. Women and White participants consistently outlived men and Black participants across risk groups. Researchers stressed the findings show association, not proven causation, and underscored the public‑health benefit of controlling vascular risk factors in midlife. The following day, a separate analysis of a large lifestyle‑intervention program reported that structured behavioral changes not only cut the risk of advanced chronic kidney disease by up to 62 % but also echoed the NYU findings, showing that maintaining cardiovascular health and addressing the same three risk factors could extend dementia‑free years by up to 13. Both reports underscore the potential of non‑pharmacological, midlife health strategies to substantially delay dementia onset while also reducing other age‑related disease risks.
