Abstract
INTRODUCTION
This study assessed the association of plasma biomarkers of endothelial dysfunction with cognitive performance and decline.
METHODS
Data from 9414 individuals from eight Dutch cohorts were included (Ø age-range: 57–93 years). Plasma biomarkers of endothelial dysfunction (soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1), soluble E-selectin) were combined into a standardized composite score. Cognitive outcomes included executive function, processing speed, immediate and delayed memory, attention, and language. Linear regressions and linear mixed models were run in the individual cohorts and standardized coefficients were subsequently pooled using random-effects meta-analyses.
RESULTS
A higher endothelial dysfunction composite score was cross-sectionally associated with worse performance on executive function, processing speed, delayed memory, and attention, but not immediate memory or language (pooled β-range: −0.04, −0.02). We found no association with change in cognition over time.
DISCUSSION
This comprehensive two-step, individual participant data (IPD) meta-analysis showed a small, consistent cross-sectional association between endothelial dysfunction and worse cognitive performance across multiple domains but no support for a longitudinal association.
Highlights
Prior evidence on endothelial dysfunction (ED) biomarkers and cognition is conflicting.
This two-step, individual participant data (IPD) meta-analysis used data from eight Dutch cohorts.
ED was consistently associated with concurrent cognition.
ED was not associated with a change in cognition over time.
The association of ED with current cognition may be generic.
