- Recent generations are less likely to develop dementia at the same age compared to earlier generations.
- Women show a more pronounced decline in dementia risk, possibly due to increased access to education in the mid-20th century.
- The study analyzed data from 62,437 people aged 70+ across the US, England, and Europe.
- Dementia prevalence increases with age but is lower in more recent birth cohorts.
- Factors like education, smoking bans, and medical improvements may contribute to the decline in dementia risk.
- The study has limitations, including reliance on algorithmic assessments rather than clinical diagnoses.
- Experts caution that the trend may not continue, as major health improvements may have already occurred.
- Nearly half of dementia cases could be prevented or delayed by addressing key risk factors like smoking and air quality.
