Older adults with a weaker hand grip were more likely to be cognitively impaired than those with a stronger grip, according to an NIA-funded study in the Journal of Alzheimer’s Disease. The findings suggest that hand grip strength may be a potential low-cost, easy way to help detect cognitive impairment and, in combination with other measures, to identify people who may benefit from early interventions.
A team led by researchers from North Dakota State University looked at data over an eight-year period from almost 14,000 people, age 50 or older, in the NIA-supported Health and Retirement Study. A handheld instrument called a dynamometer was used to assess hand grip strength, and a modified screening tool from the Mini-Mental State Examination was used to measure cognitive function every two years. Of the 13,828 participants who were assessed, 1,309 had some degree of cognitive impairment. Continue reading
