Most healthcare systems have underestimated the power of data—until now. Naval Roy reveals how he's building the world's largest, most sophisticated mental health and neurodegeneration database to revolutionise diagnosis, treatment, and prevention.

In this episode, discover how decades of hidden healthcare data can be transformed into a cutting-edge infrastructure that accelerates breakthroughs in neuroscience. Nawal shares the story of acquiring a 20-year, half-a-million patient database from Duke University—an investment of over $70 million and years of relentless engineering. This data refinery is now shaping the future of personalised medicine, enabling real-world evidence, predictive analytics, and AI-driven interventions at scale.

The stakes are enormous: mental health and neurodegenerative diseases cost trillions, yet current approaches are hamstrung by outdated models rooted in philosophy and fragmented data architectures. Nawal emphasises the importance of moving beyond the 'sick care' paradigm to proactive healthspan extension and prevention—using data to predict, prevent, and personalise care long before symptoms appear.

Key Takeaways

• Data-driven healthcare accelerates discovery by transforming entire sectors from opinion-based to evidence-based decision making.
• The true value of healthcare data lies in its ability to inform early intervention and prevention, not just treatment.
• Philosophical assumptions like Descartes’ mind-body dualism distort current biomedical models, enforcing unnecessary specialization and separation.
• The complexity of mental health and neurodegenerative disorders requires cross-disciplinary, AI-enabled modelling of multifactorial data.
• Building extensive, high-quality datasets is a multi-year, multi-million-dollar endeavour that demands patience, capital, and relentless focus on data curation.
• Democratising access to large healthcare data accelerates research and innovation by empowering a broad base of scientists, clinicians, and entrepreneurs.
• The biggest business opportunities in healthcare data are generated when multiple stakeholders—pharma, payers, governments—interact on shared, verified assets.

Why do we do things we know we’ll regret?

Why is it so hard to pause in the moment… and choose differently?

From snapping at someone you care about, to habits you keep falling back into, these split-second decisions can quietly shape the direction of your life.

In this episode, Carly unpacks what’s really happening in those moments when the impulse feels stronger than you… and a technique to stop getting pulled under by it.
