Millions of older adults have tiny brain hemorrhages called cerebral microbleeds, which are strongly associated with dementia, cognitive decline, and stroke.

Researchers at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have created one of the largest reference models ever developed for the human brain, using diffusion MRI scans from more than 54,000 people to chart how the brain's communication pathways develop, mature, and decline across the lifespan.
