Digital Biomarkers and the Future of Longitudinal Brain Health
Researchers at the UCSF Neuroscape research center and Samsung are launching the Technology for Aging Health – Digital Approaches (TAH-DA) study, a longitudinal effort to identify biometric predictors of cognitive decline. By pairing Samsung’s Galaxy Watch and Galaxy Tab A9 with Neuroscape’s proprietary software, the study aims to track cognitive health across the adult lifespan in real-world settings rather than static laboratory environments.
How the TAH-DA Study Tracks Cognitive Function
The study recruits 200 adults from each decade of life between ages 40 and 89 to monitor health metrics over a 12-month period. According to Neuroscape, the goal is to determine which passive biometric measures—such as heart rate, ECG, blood pressure, and sleep patterns—correlate with cognitive performance.
Participants utilize the Galaxy Watch for continuous data collection, while the Galaxy Tab A9 serves as a platform for digital cognitive assessments and interventions. These interventions consist of cognitively challenging games developed by Neuroscape. Researchers measure performance at three key intervals: before the intervention, immediately after, and nine months post-intervention.
The Role of Wearable Technology in Preventive Healthcare
The collaboration is part of Samsung’s Open Innovation Initiative, which seeks to integrate consumer electronics into the digital health ecosystem. Praveen Raja, Vice President of Digital Health at Samsung Research America, stated that the company aims to use biometric data to identify behavioral and physiological predictors of cognitive decline.
Mobile devices capture subtle routine changes with high sensitivity, providing researchers with a rich, longitudinal dataset. Adam Gazzaley, executive director of Neuroscape, described the partnership as the most technologically ambitious remote trial the team has attempted. By combining Samsung’s hardware with Neuroscape’s software, the project aims to generate new insights into how cognitive function shifts as people age.
Future Directions for Remote Clinical Trials
The TAH-DA study represents a shift toward remote, technology-driven clinical research. Theodore Zanto of Neuroscape noted that the team hopes to raise the bar for remote trials by pushing the bounds of neurotechnology. The ultimate objective is to develop deployable algorithms that can track changes in brain health, potentially leading to new digital treatments for cognitive health.
