abstract = {Blood-derived microRNAs (miRNAs) are potential candidates
for detecting and preventing subclinical cognitive
dysfunction. However, replication of previous findings and
identification of novel miRNAs associated with cognitive
domains, including their relation to brain structure and the
pathways they regulate, are still lacking.We examined
blood-derived miRNAs and miRNA co-expression clusters in
relation to cognitive domains, structural magnetic resonance
imaging measures, target gene expression, and genetic
variants in 2869 participants of a population-based
cohort.Five previously identified and 14 novel miRNAs were
associated with cognitive domains. Eleven of these were also
associated with cortical thickness and two with hippocampal
volume. Multi-omics analysis showed that certain identified
miRNAs were genetically influenced and regulated genes in
pathways like neurogenesis and synapse assembly.We
identified miRNAs associated with cognitive domains, brain
regions, and neuronal processes affected by aging and
neurodegeneration, making them promising candidate
blood-based biomarkers or therapeutic targets of subclinical
cognitive dysfunction.We investigated the association of
blood-derived microRNAs with cognitive domains. Five
previously identified and 14 novel microRNAs were associated
with cognition. Eleven cognition-related microRNAs were also
associated with cortical thickness. Identified microRNAs
were linked to genes associated with neuronal functions.
Results provide putative biomarkers or therapeutic targets
of cognitive aging.},
