Abstract

Dynapenia is the age-related loss of muscle strength. Decreased muscle strength, including handgrip strength, is associated with cognitive impairment in older adults, possibly due to weakening of the neuromuscular system. However, changes in muscle strength and cognitive function may occur simultaneously and reflect aging. We aimed to investigate the relationship between repeated measures of muscle strength and changes in cognitive function and new-onset mild cognitive impairment (MCI) in middle-aged and older adults.

Research summary

The paper investigates the relationship between changes in muscle strength and cognitive function in middle-aged and older adults. This research is relevant as it explores the interplay between physical and cognitive decline, which are critical aspects of aging and longevity.
