Objective: We sought to determine the associations of cognitive impairment consistent with dementia (CICD) diagnosis status on handgrip strength, gait speed, and functional disability in older adults. Methods: The analytical sample included 8,383 adults aged \u226565-years without history of stroke, cancers, neurological conditions, or brain damage who participated in at least one-wave of the 2010\u20132016 waves of the Health and Retirement Study. A handgrip dynamometer measured handgrip strength. Men with handgrip strength &lt;26\u200akg and women &lt;16\u200akg were weak. Gait speed was timed across a 2.5-m course and those with slowness had gait speed &lt;0.8\u200am\/s. Participants with difficulty or an inability in completing any basic activities of daily living had a functional disability. The adapted Telephone Interview of Cognitive Status evaluated cognitive function. Persons with scores &lt;7 had a CICD. Healthcare provider dementia-related diagnosis was self-reported. Undiagnosed CICD was defined as no reported dementia-related diagnosis but had CICD, while diagnosed CICD was classified as reporting a dementia-related diagnosis. Covariate-adjusted logistic models were used for the analyses. Results: Persons with undiagnosed CICD had 1.37 (95% confidence interval (CI): 1.04\u20131.80) greater odds for weakness and 2.02 (CI: 1.39\u20132.94) greater odds for slow gait speed. Older adults with diagnosed CICD had 2.29 (CI: 1.32\u20133.97) greater odds for slowness and 1.85 (CI: 1.19\u20132.90) greater odds for functional disability. Conclusion: Screening for CICD could be recommended when defects in physical function are observed in older adults.<\/jats:p>","DOI":"10.3233\/jad-220257","type":"journal-article","created":{"date-parts":[[2022,7,26]],"date-time":"2022-07-26T13:29:51Z","timestamp":1658842191000},"page":"473-482","source":"Crossref","is-referenced-by-count":2,"title":["Undiagnosed
