Can policy lower dementia risk at scale? Who isn't interested in this question? The Nottingham consensus just weighed in. A modified Delphi process is a structured method that brings experts together (through multiple rounds of questions and answers) to reach agreement on complex topics, especially when evidence is evolving. Demnitz-King and colleagues describe in a new paper in Nature Reviews Neurology how an international expert panel reached consensus on actionable dementia risk reduction policies to try to move evidence into real world public health action. Key Points: - The panel reached consensus on 56 policy recommendations spanning public health messaging, individual level interventions, population level interventions and research priorities. - A central theme was that dementia risk reduction must address health inequalities in order to avoid widening existing gaps. - Clear consistent messaging should emphasize reducing dementia risk rather than preventing or stopping dementia. My take: This paper shifts the conversation from what individuals should do, to what systems must do. Dementia risk reduction will only succeed if policy aligns science equity and sustained investment across the life course. Here are 5 points that resonated w/ me: 1- Dementia risk reduction is possible, however it requires coordinated policy not just individual behavior change. 2- Messaging matters and words like ‘reduce risk’ are more accurate and trustworthy than absolute promises. 3- Population level actions on air pollution education, hearing loss and cardiovascular health may deliver the biggest gains. 4- Addressing social and economic inequities will be essential if we want prevention to reach all folks. 5- The future of dementia prevention depends on sustained research, funding, data infrastructure and cross government commitment. https://www.nature.com/articles/s41582-025-01173-9 #parkinson #michaelokun #dementia #alzheimer
