This policy brief provides a strategic overview of the need to standardise risk factors associated with dementia and frailty across Europe. In the context of an ageing population and the current fragmentation of health data, the document highlights the importance of moving towards a common framework that enhances interoperability, supports the development of artificial intelligence–driven solutions, and enables more precise and effective health policymaking. Through practical recommendations, it outlines how fragmented data can be transformed into actionable insights to improve prevention and care across the European Union.
