Cerebral vascular disease Definition of term The term cerebrovascular disease designates any abnormality of the brain resulting from a pathologic process of the blood vessels. Sudden loss of neurological function is the hallmark of cerebrovascular disease Cerebrovascular disease is the third most common cause of death and the most common disabling neurologic disorder in western civilized countries where an increasing proportion of people survive to old age. Shanghai is entering the aging society Its incidence increases with age and is somewhat higher in men than in women

I Cerebral ischaemia and infarction Anatomy and pathology The principal pathological process under consideration here is the occlusion of arteries supplying the brain. The two internal carotid arteries and the basilar artery form the Circle of willis at the base of the brain, which acts as an efficient anatomotic device in the event of occlusion of arteries proximal to it
