A handgrip dynamometer measured handgrip strength. Men with handgrip strength &lt;26 kg and women &lt;16 kg were weak. Gait speed was timed across a 2.5-m course and those with slowness had gait speed &lJournal of Alzheimer's disease : JADUndiagnosed Dementia Is Associated with Poor Physical Function in Older Adults.PMC10171085U01 AG009740K01 AG065420Robinson-Lane SGMcCourt MEHamm JMKlawitter LParker KRhee YHackney KJMcGrath RfalseUndiagnosed Dementia Is Associated with Poor Physical Function in Older Adults.<h4>Background</h4>Older adults with a cognitive impairment, including those not yet diagnosed, may have deficits in their physical function.<h4>Objective</h4>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.<h4>Methods</h4>The analytical sample included 8,383 adults aged ≥65-years without history of stroke, cancers, neurological conditions, or brain damage who participated in at least one-wave of the 2010-2016 waves of the Health and Retirement Study.
