At CES next month, where it’s holding a product launch in its own standalone exhibition space, Samsung is now rumored to be demonstrating a new Brain Health feature that detects early signs of dementia.
This will work by analyzing various metrics, and will join Samsung’s many other preventative healthcare features, which include blood pressure monitoring, ECG, and irregular heart rhythm notifications.

The new Brain Health feature will use data collected by Samsung smartphones and smartwatches, including gait patterns, changes in a user’s voice, and sleep status. Based on analysis of this data, it will identify cognitive decline and early signs of dementia.
If it does, then it will provide guidance on preventative measures (which, it would seem, would be too late) as well as a customized “brain training” program to help improve cognitive abilities (if it works). This feature was reportedly developed in-house by the Korean company and it is now conducting clinical validation trials in partnership with medical institutions. It’s unclear when Brain Health will actually be released.
