Stroke. Computer artwork of a stroke (centre) seen inside brain. Strokes (or cerebrovascular accidents,CVA) occur when a blood vessel in the brain is blocked or bursts,as here. Parts of the brain that are deprived of blood,and hence their oxygen supply,will die. Symptoms of a stroke depend on extent and location of brain damage. They vary from headaches and dizziness to paralysis and death. Strokes typically occur in the elderly and are a major cause of death | |
