A stroke is a kind of brain injury that may happen in various areas of the brain. It is more common in older adults, who are about 65 years-old and above. There are two types of strokeâ€”ischemic and hemorrhagic. Ischemic stroke is when the blood vessels are blocked and oxygenated blood is prevented from reaching the brain and this causes damage. Hemorrhagic stroke is when the blood vessels in the brain rupture or burst because of fragility or extreme high blood pressure. This causes damage to the brain tissues because the oxygenated blood does not circulate in the brain anymore.
