Three Factors Tied to 13 Additional Dementia-Free Years

A recent study examining the impact of three key health factors during midlife on dementia-free survival has found that maintaining normal blood pressure, no diabetes, and not smoking can add nearly 13 additional dementia-free years to an individual's life. The research, conducted on 12,000 people in the U.S., showed that those who met these criteria at age 55 lived an average of 30.1 more years dementia-free.

Conversely, individuals who smoked, had hypertension, and had diabetes at age 55 had dementia-free survival of only 17.5 years. The study, published in Neurology Open Access, underscores the importance of actively avoiding these risk factors in midlife to preserve brain health for more than a decade.
