Relationship Between Sarcopenia and Cognitive Function in Community-Dwelling Older Adults

Objectives: Sarcopenia, known as muscle bulk and strength loss, along with cognitive impairment, are frequently observed in the aging population. Although both conditions are prevalent, their potential interplay has not yet been clearly defined. It was aimed to explore the link between sarcopenia and cognitive functions in the older adult population.Materials and Methods: Fifty-five older adults with an average age of 73.34 ± 6.65 participated in the study. While cognitive functions were examined using the Mini-Mental State Examination (MMSE), the risk of sarcopenia was determined using the Sarcopenia Screening Questionnaire (SARC-F). Additionally, functional mobility and hand grip strength were measured using the “Timed Up and Go (TUG)” test and the “Four-Meter Walk Test”.Results: Of the participants, 56.4% exhibited cognitive impairment, and 52.7% were at risk of sarcopenia. Correlation analysis revealed significant relationships between MMSE scores and SARC-F (r=-0.741), dominant (r=0.577) and non-dominant grip strength (r=0.549), the TUG test (r=-0.714), and the Four-Meter Walk Test (r=-0.752) (p
