A review of dementia-prevention efforts across eight countries found broad public campaigns usually produced only small gains in knowledge and limited changes in behavior.
Interactive programs worked better, with the strongest approach—personalized risk assessment plus structured education—improving modifiable risk-factor status by 26% over three years.
Researchers said the gap is not awareness alone: many people still see dementia as inevitable, even though the 2024 Lancet Commission estimated about half of cases could be prevented or delayed by addressing 14 risk factors.
Outside clinicians said the findings match practice, where patients often know basic risks but fail to act; one cited survey data showing knowledge as high as 95% for diet versus healthy sleep habits as low as 33%.
The study points public health efforts toward scalable but more personalized tools—online education, individual risk profiling and community programs—to turn prevention messages into sustained lifestyle change.

Preventing 45% of Dementia: Global Evidence and Strategies from LatAm-FINGERS and Multidomain Interventions
Overview
The LatAm-FINGERS trial has shown that multi-domain lifestyle interventions can improve brain health and reduce dementia risk across diverse populations, including those with different cultural backgrounds and socioeconomic status. Building on the adaptable U.S. POINTER formula, these programs combine diet, exercise, cognitive training, and social engagement, and are most effective when structured and personalized. Evidence from long-term studies like ACTIVE highlights the unique benefits of speed training for dementia prevention. To make a global impact, prevention strategies must be accessible, culturally relevant, and supported by trained personnel, community programs, and policy integration, ensuring both sustainability and support for caregivers.
