Samsung Unveils New ‘Brain Health’ Feature for Early Dementia Detection

The feature is currently undergoing clinical review with specialised institutions in South Korea and other countries.

Samsung has unveiled a new ‘Brain Health’ feature that uses data from its wearables and smartphones to identify early signs of dementia, positioning everyday consumer devices as tools for early cognitive risk detection.

The new service has been designed to help detect early signs of dementia by analysing subtle behavioural and physiological changes captured through Galaxy wearables and connected smartphones, reinforcing the growing role of wearable health technology in everyday life.

The announcement builds on Samsung’s expanding digital health ecosystem, which already includes sleep tracking, heart rhythm monitoring, and sleep apnea detection. With Brain Health, the company is extending its focus beyond physical health into cognitive wellbeing.

Dementia currently affects tens of millions of people worldwide, with cases expected to rise sharply as populations age. Early detection is widely recognised as critical for slowing progression and improving quality of life, yet traditional screening often happens late and requires clinical settings. By contrast, wearable health tools offer continuous, passive monitoring in familiar environments, making early signals easier to capture.

Praveen Raja, Vice President and Head of Digital Health at Samsung, noted that wearables can pick up subtle behavioural changes that often go unnoticed in daily life.

Samsung has also said the Brain Health service will eventually support personalised exercise and sleep coaching, using insights from connected devices to help users reduce the risk of chronic diseases linked to cognitive decline. This aligns with broader trends in digital health, where wearables are increasingly used not only to track health metrics but to guide preventive lifestyle changes.

The feature is currently undergoing clinical review with specialised institutions in South Korea and other countries. Samsung plans to launch Brain Health in beta in select markets, allowing the company to refine the system based on real-world feedback before a wider rollout.

Privacy and data protection remain central considerations, with Samsung emphasising secure data handling and user consent.
