Small artery Disease: Diffuse chronic ischemic changes in the brain are often reported on MRI scans of those over 50. Diffuse: scattered through the brain. Chronic: it's been there awhile. Ischemic: not enough blood. Neuroscientists believe this is small arteries not supplying enough blood in tiny areas of brain. Some tiny brain areas stop working w/o adequate blood supply; this is seen as white dots/spots on MRI
