Cerebrovascular disease refers to
a group of conditions, diseases, and disorders that affect the blood vessels
and blood supply to the brain. If a blockage, malformation, or hemorrhage
prevents the brain cells from getting enough oxygen, brain damage can result.
Cerebrovascular disease can develop from a variety of causes, including
atherosclerosis, where the arteries become narrow; thrombosis, or embolic
arterial blood clot, which is a blood clot in an artery of the brain; or
cerebral venous thrombosis, which is a blood clot in a vein of the brain.
Cardiovascular disease is a
disease of the blood vessels in the heart, and cerebrovascular disease is a
disease of the blood vessels in the brain. The same risk factors cause them.
Cerebrovascular diseases include
stroke, transient ischemic attack (TIA), aneurysm, and vascular malformation.
