Supported by Horizon Europe, the DORIAN GRAY initiative stands as a compelling example of how the Innovative Health Initiative (IHI), previously the Innovative Medicines Initiative (IMI), vision—placing patients at the centre of health innovation—is being translated into concrete action. Dedicated to the prevention of cognitive decline in individuals with cardiovascular disease, the project combines advanced technology with deep patient engagement to deliver truly meaningful solutions. 

The core idea revolves around the use of AI-driven digital twins, virtual models that simulate each patient’s evolving clinical profile by integrating medical, behavioural, and biometric data. These personalised models allow for early identification of cognitive risks, opening the door to timely and tailored interventions. 

Yet the technological ambition is only part of the story. What truly defines the project is its commitment to co-creation. From the very beginning, people living with cardiovascular conditions and early cognitive challenges have been actively involved in shaping the digital tools being developed. Their input has helped guide the design of a gamified avatar platform, which blends physical exercise with cognitive training in a way that is accessible, engaging, and aligned with users’ needs. 

This approach reflects a growing awareness that patient experience is essential to effective innovation. Instead of offering solutions designed in isolation, the project listens to those it aims to help—ensuring that tools are not only scientifically sound, but also usable and relevant in everyday life. 

The importance of this philosophy is also underlined in a recent IHI article, “Patients as partners – how IHI and IMI engage patients in health research”, which highlights how involving patients from the earliest stages of research is vital to creating innovations that are both effective and practical. The DORIAN GRAY project embodies this principle, showing how the IHI commitment to ‘patients as partners’ can move beyond rhetoric and become a living part of European health research. 

By merging artificial intelligence with real-world insight, this initiative demonstrates how complex technologies can be made human, empathetic, and empowering—paving the way for healthcare solutions that truly improve lives.
