The Personalized Multi-Domain Digital Platform for Dementia Prevention (PM(DP)*2) is a conceptualized evidence-based initiative designed to reduce dementia burden through tailored interventions. By collecting and analyzing multidimensional data on modifiable risk factors, including lifestyle, cardiovascular health, and environmental exposures, the platform creates individualized risk profiles and recommends personalized prevention strategies. Machine learning models and generative AI enhance the platform's ability to offer dynamic, evidence driven recommendations.
