Abstract

Cognitive decline is a common aspect of aging, and identifying modifiable lifestyle factors-such as physical activity and sleep-are crucial for promoting healthy brain aging. While both are individually linked to cognition, few studies have simultaneously assessed their independent and combined effects using objective wearable-based data, particularly in older Asian populations.

Research summary

The paper claims that both sleep and physical activity, as measured by wearables, are associated with memory performance in older adults. This research is relevant as it explores modifiable lifestyle factors that could contribute to healthier brain aging, addressing the root causes of cognitive decline in the aging population.
