Proteomic analysis of paired cerebrospinal fluid and plasma samples from 2,171 individuals drawn from multiple cohorts, including the Global Neurodegeneration Proteomics Consortium, reveals age-related changes in the ratios of proteins in the cerebrospinal fluid and plasma that are associated with cognitive function, enhancing understanding of blood–brain barrier dynamics in aging.
