					<description><![CDATA[A two-year study of 506 older adults in the COSMOS cohort found that plasma biomarkers of neurodegeneration, including NT1, NfL, and oAβ, largely failed to predict declines in walking speed, grip strength, and physical performance, with only changing NT1 levels tracking concurrent grip strength changes.]]></description>
