Cambridge Cognition Holdings, based in Cambridge, UK, has announced a collaboration with Oura to conduct a significant brain health study that will integrate cognitive evaluations with physiological data collected from Oura's smart ring. The study, which has received approval from an institutional review board, aims to enroll up to 45,000 members of Oura. Participants will complete brief cognitive assessments through the Oura app, while the ring continuously monitors sleep, activity, stress, and other physiological metrics. This observational research program will extend until 2026 and will utilize Cambridge Cognition's cognitive assessments, including CANTAB Pathway, CANTAB One, and CANTAB Insight, as short tasks within the app. The study will explore the relationships between behavioral, biometric, and cognitive measures over time. Rob Baker, CEO of Cambridge Cognition, emphasized the collaboration's role in expanding the reach of cognitive assessments into health and consumer applications beyond traditional clinical and research settings.
