Cerebrovascular Disease. The word cerebrovascular is made up of two parts â cerebro which refers to the large part of the brain, and vascular which means arteries and veins. Together, the word cerebrovascular refers to blood flow in the brain. The term cerebrovascular disease includes all disorders in which an area of the brain is temporarily or permanently affected by ischemia or bleeding and one or more of the cerebral blood vessels are involved in the pathological process.
A cerebrovascular accident is also called a CVA, brain attack, or stroke. It occurs when blood flow to a part of the brain is suddenly stopped and oxygen cannot get to that part. This lack of oxygen may damage or kill the brain cells. Death of a part of the brain may lead to loss of certain body functions controlled by that affected part.
