We aim to investigate the association of cerebral deep medullary veins (DMVs) with white matter microstructural integrity and regional brain atrophy in MRI. In a community-based cohort of 979 participants, DMVs were identified on susceptibility-weighted imaging. Brain structural measurements, including gray matter and hippocampus volumes and diffusion tensor metrics, were evaluated. A smaller number of DMVs was related to lower fractional anisotropy and higher mean diffusivity in multiple voxels on the white matter skeleton. Fewer DMVs were significantly associated with lower gray matter and hippocampal fractions. A significant correlation between DMVs’ reduction and cortical atrophy was observed in the bilateral occipital, temporal, hippocampal, and frontal lobes.
