Recent research indicates that reduced muscle strength and slower movement in older adults may be linked to a higher risk of late-life dementia. Simple, inexpensive muscle function tests, such as grip strength and timed-up-and-go (TUG) tests, could be critical in identifying individuals at risk for dementia and implementing preventive measures. A study conducted by Edith Cowan University analyzed data from over 1,000 women with an average age of 75, revealing that those with lower grip strength and slower TUG performance were significantly more likely to experience dementia-related events.
Specifically, women with the weakest grip strength were more than twice as likely to encounter dementia compared to those with stronger grips. Additionally, a decline in grip strength and TUG performance over five years corresponded with a greater risk of dementia. For example, participants with significant declines in TUG performance were more than four times more likely to suffer dementia-related deaths. Researchers emphasize that grip strength may serve as a proxy for brain health, as cognitive decline and motor function impairments are interconnected. Incorporating these tests into clinical practice could enhance dementia screening and identify high-risk individuals, allowing for early intervention through lifestyle changes. Further research is encouraged to explore this area.
