New study finds dementia risk declines each generation

A new study indicates that the risk of developing dementia is declining with each successive generation, offering a hopeful outlook despite rising global dementia cases. Researchers analyzed health survey data from the US, Europe, and England, finding that younger birth cohorts showed lower dementia prevalence rates, particularly among women. The study compared age-specific dementia rates across different age groups. While the study's findings may not apply to all populations, the results suggest that the percentage of people affected by dementia could decrease, impacting healthcare planning and long-term care policies.
