The Relationship Between Handgrip Strength and Cognitive Ability in the Elderly with Early-Stage Dementia

(1) Background: Alzheimer’s disease is a common neurodegenerative disease which mainly affects the elderly. The aim of the study is to investigate the relationship between handgrip strength and cognitive ability in a geriatric population with early-stage dementia. There are only a few studies that associate handgrip strength with cognitive ability in a population with early-stage dementia. (2) Methods: The present study consists of a sample of 60 individuals with early-stage dementia and was conducted at the Alzheimer’s Association of Athens. Participants’ ages ranged from 65 to 93 years (M = 80 years, SD = 6.05). Specific inclusion and exclusion criteria of the sample were defined. Handgrip strength was assessed using a digital handheld dynamometer, while cognitive ability was measured using the Mini-Mental State Examination Test (MMSE). (3) Results: Descriptive statistics showed that the mean handgrip strength of the dominant upper limb was 144.45 ± 50.47 Newtons, and the mean cognitive score was M = 21.75 (SD = 1.97) (0–30 points). In a multivariable regression analysis adjusted for age, sex, and education, handgrip strength was not significantly associated with MMSE score (B = 0.056, 95% CI: −0.054 to 0.166, p = 0.314). (4) Discussion: There are few studies that correlate cognitive ability with handgrip strength in a population with early-stage dementia; thus, further studies are needed to investigate the present results, possibly with a larger sample size or using different cognitive function measurement tools. (5) Conclusions: Handgrip strength may appear not to be associated with cognitive ability when elderly patients are in early-stage dementia. More research should be conducted to confirm the present findings.
