Tissue- and compartment-resolved brain age reveals vascular-metabolic and neurodegenerative aging

Brain aging reflects heterogeneous vascular-metabolic and neurodegenerative processes, yet brain age is often reduced to a gray matter (GM)-dominant estimate. Emerging evidence suggests that subtle “dirty-appearing” T2-FLAIR abnormalities may mark diffuse white matter (WM) vulnerability that precedes or extends beyond...

Genome-wide analysis of subcortical aging identifies a spatially structured pattern of genetic associations.

This work presents the first genome-wide association study (GWAS) of subcortical LBA, estimated using a deep neural network applied to T1-weighted MRI scans from 41,957 cognitively normal participants in the UK Biobank, and identifies 14 significant single-nucleotide polymorphisms across nine independent loci.
