Abstract:	Silent brain infarcts (s) are highly prevalent in the aged population and relate to the occurrence of further stroke and dementia. Serum N-glycome levels have been previously associated with aging and they might be related as well to the presence of s and age-related white matter hyperintensities. We determined the serum N-glycome profile in a cohort study comprising 972 subjects and evaluated the relationship between N-glycome levels and the presence and number of s and with age-related white matter hyperintensities grades, assessed by brain magnetic resonance imaging. Decreasing concentrations of bigalacto core-α-1,6-fucosylated biantennary glycan and increasing concentrations of branching α-1,3-fucosylated triantennary glycan remained as independent predictors of s (odds ratio 0. 4, 95% 0. 3-0. 7 and odds ratio 1. 8, 95% 1-3. 2, respectively), after controlling for the presence of age and classic vascular risk factors. A similar pattern was found to be related to an increasing number of s and white matter hyperintensities grade. N-glycome levels might be potentially useful as biomarkers for the presence of silent cerebrovascular disease.
