Global Collaborative Research on Establishing a Korean Cognitive Aging Cohort
This observational study is tracking how daily emotional stress affects memory and thinking over time in Korean adults aged 60 and older. Participants use a smartphone app for real-time mood and cognition check-ins, wear a Galaxy Watch, and give blood samples to measure inflammation markers. Researchers will follow them at 6 months and 1 year. This is a cohort study, not a clinical trial testing a treatment — it is designed to build knowledge, not test an intervention.
