Launch of brain health study with Oura

Cambridge Cognition and Oura launch large-scale brain health study integrating cognition with wearable sleep and physiological data

Cambridge, UK, 28 May 2026: Cambridge Cognition Holdings plc (AIM: COG), the neuroscience technology company whose digital cognitive assessments drive scientific discovery, accelerate drug development and improve patient care, announces a collaboration with ŌURA, maker of the world's leading smart ring, on a new institutional review board (IRB)-approved brain health study. Conducted through Oura Labs, an experimental innovation platform within the Oura App, the study pairs Cambridge Cognition's scientifically validated digital cognitive assessments with Oura's continuous physiological data. Rather than focusing only on diagnosed disease, this work explores how everyday patterns in rest, stress, and behaviour may relate to cognitive function and performance over time.

Oura has established one of the world's leading consumer health platforms, with sensing technology spanning sleep, activity, stress, cardiovascular and metabolic health and more, alongside partnerships with more than 1,200 leading organisations across health, wellness, and commercial brands.

Cambridge Cognition's scientifically validated digital cognitive assessments from CANTAB Pathway™ have been integrated into the Oura platform as short in-app tasks, specifically CANTAB One and CANTAB Insight. As part of this large-scale remote observational research programme running through 2026, up to 45,000 participating Oura members will complete these brief assessments alongside continuous monitoring of their sleep, activity, stress and physiological measurements captured by Oura Ring.

The study is intended to explore relationships between behavioural, biometric and cognitive measures over time, helping advance understanding of how factors such as sleep, recovery and activity may influence brain health and cognition. The programme is also designed to assess user engagement with consumer-integrated cognitive assessments alongside wearable-derived and self-reported health data. Insights generated from these combined datasets are expected to help inform future product development and scalable brain health applications.

The collaboration builds on the recent expansion of CANTAB Pathway™ across healthcare and consumer markets and reflects Cambridge Cognition's strategy of making its cognitive assessments more accessible through scalable digital platforms. Building on previous programmes including Project Intuition, a 23,000-participant remote cognitive assessment study conducted with Biogen and Apple, this demonstrates the Company's ability to deploy validated cognitive measurement at scale and generate rich longitudinal insight into cognitive function.

Rob Baker, CEO, Cambridge Cognition said, "Oura combines strong scientific credibility with significant consumer reach, making them an ideal partner on this study as we seek to expand CANTAB Pathway™ into broader healthcare and consumer applications. Bringing together trusted cognitive science with wearable-derived physiological data is a powerful way to support scalable approaches to brain health measurement, and to extend the reach of our technology beyond traditional clinical and research environments."

"Cognitive health is one of the least understood frontiers in preventive medicine," said Shyamal Patel, Ph.D., Senior Vice President of Science at Oura. "By pairing validated cognitive assessments with continuous sleep, activity, and physiological sensing, this Brain Health Study allows us to rigorously explore how everyday biometrics and behaviors relate to cognitive performance over time, laying a scientific foundation for future tools that can help people understand and support their long-term brain health."
