Abstract

Single-measure sleep duration has been extensively studied in association to cognitive impairment. However, this approach overlooks the potential impact of long-term sleep duration trajectories on cognitive function. The present study aims to identify distinct long-term sleep duration trajectories and prospectively assess their association with the risk of cognitive impairment in Chinese elderly individuals.

Research summary

The paper claims that distinct long-term sleep duration trajectories are associated with the risk of cognitive impairment in elderly individuals. This study is relevant as it explores the relationship between sleep patterns and cognitive decline, which are critical factors in understanding aging and age-related diseases.
