Stroke, conceptual image. Coloured angiogram (blood vessel X-ray) of the cerebral arteries. A stroke, or cerebrovascular accident (CVA), is where the brain is damaged by hypoxia (lack of oxygen). This is usually due to an interruption of, or other damage to, the blood supply, such as a burst blood vessel (haemorrhagic stroke) or a clot (ischaemic stroke) blocking the blood flow to the brain. | |
