A major new analysis of over 62,000 individuals aged 70 and above across the U.S., England, and Europe indicates that people born in more recent decades face significantly lower risk of developing dementia at a given age than previous generations .

For instance, among those aged 81 to 85, 25.1% of individuals born between 1890 and 1913 had dementia, compared to just 15.5% of those born between 1939 and 1943  .

Experts credit this encouraging trend to improvements in education—especially for women—as well as better cardiovascular health, smoking reductions, and advanced medical treatments for risk factors like hypertension and diabetes.

However, they caution that the total number of dementia cases will still climb due to aging populations. Continued public health initiatives aimed at education, disease prevention, and environmental improvements will be essential to maintain and build upon this momentum  .
