Any disease affecting an artery in, and supplying blood to, the brain: for example, atherosclerosis (narrowing of the arteries) or defects or weaknesses in arterial walls causing aneurysm (a balloon-like swelling in an artery). The disease may eventually cause a cerebrovascular accident, which commonly leads to a stroke. Extensive narrowing of blood vessels throughout the brain can be a cause of dementia.
