A recent study published in Nature Medicine reveals that the risk of developing dementia may be much higher than previously estimated. Earlier research suggested that around 14% of men and 23% of women would develop dementia in their lifetimes. However, the new findings show that the risk is closer to 42% for both men and women.
Dr. Josef Coresh, the study leader and director of the Optimal Aging Institute at NYU Grossman School of Medicine, explains that the rise in dementia cases is largely due to people living longer. The number of people affected by dementia is expected to double by 2060, with the greatest increase seen among Black Americans, where the risk is predicted to triple.
The study tracked over 15,000 people in the U.S. for more than 20 years. It found that the risk of dementia for a 55-year-old is about 42%, but this increases significantly after age 85. By age 95, the risk reaches 42%. For Black Americans and women, the risk was even higher, especially in later years.
While factors like genetics and structural inequalities contribute to higher risk, lifestyle changes such as controlling high blood pressure, managing diabetes, and getting enough sleep can help reduce the chances of developing dementia. The study emphasizes that dementia is not inevitable and can be prevented in many cases with proper care.
