Recent mathematical modeling has allowed for the delineation of arterial stiffness caused by structural remodeling (S) and blood pressure, termed \u201cload-dependent\u201d stiffening (LD). While we recently demonstrated that S-PWV and LD-PWV are differentially associated with risk for cognitive decline and AD\/ADRD brain imaging biomarkers, the associations between paired measures of S-PWV and LD-PWV with cognitive function, AD\/ADRD brain imaging biomarkers, and plasma AD biomarkers have not been assessed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>To conduct a comprehensive analysis combining cross-sectional data from the Wake Forest Alzheimer's Disease Research Center.
