We used a mass spectrometry-based technique to quantify proteins in LDL isolated from plasma collected at the ARIC Visit 5. Linear or logistic regression was applied to evaluate the associations between individual LDL protein or LDL-C and (1) brain amyloid deposition (yes or no), (2) temporal-parietal meta-ROI brain volume (a biomarker of AD-related neurodegeneration), or (3) WMH volume, adjusting for covariates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Participants' average age was 76.3 years with a standard deviation of 5.4, and females comprised 53.8% (35 out of 65). The estimated effect sizes of many LDL protein's associations with these neuroimaging measures were larger than that of LDL-C. The strongest association was higher LDL apolipoprotein C1 (apoC1) and lower WMH volume.
