Recently conducted research indicates that people born more recently are at a reduced risk of dementia compared to earlier generations, a trend particularly notable among women. The study, analyzing data from 62,437 participants aged 70 and above across the US, UK, and Europe, found that while dementia prevalence rises with age, younger cohorts are less likely to develop it at the same age as their predecessors. However, experts caution that the overall dementia burden will still increase as populations age, with ongoing disparities by gender and socioeconomic factors.
In the US, among people aged 81 to 85, 25.1% of those born between 1890-1913 had dementia, compared to 15.5% of those born between 1939-1943.
The overall burden of dementia will still grow as populations age, and significant inequalities remain especially by gender, education, and geography.
