Galaxy phone maker Samsung will turn its Galaxy Watch into a device that detects dementia and early signs of cognitive decline.
This groundbreaking dementia diagnostic feature will be integrated in the form of a health feature called Brain Health, which will be showcased during CES 2026 in Las Vegas.
Brain Health analyzes daily data collected from Samsung smartphones and wearables, including voice patterns, gait changes and sleep behavior. By monitoring these patterns over time, the system can identify potential cognitive changes and alert users or caregivers if irregularities are detected.
Samsung’s reported primary goal of this feature is not to replace doctors, but to provide early warnings that prompt timely medical intervention.
The system will also integrate with the Samsung Health ecosystem across devices such as the Galaxy Watch and Galaxy Ring, which includes various health metrics including sleep, fitness, heart health and nutrition.
Taking privacy into account, Samsung ensures that sensitive health data is processed directly on the device, protecting personal insights and providing real-time analytics. To secure this information, Samsung Knox technology has been implemented.
Right now, Samsung has completed most of the development for Brain Health and is testing it in collaboration with medical institutions.
Although Brain Health’s exact launch date and supporting devices have not been confirmed, it is in its final stages and will be crucial to Samsung’s health strategy.
