A stroke is a sudden loss of brain function that occurs when the flow of blood to the brain is stopped by a blood clot (ischemic stroke) or the rupture of blood vessels in the brain (hemorrhagic stroke). This interruption of blood flow damages brain cells. Depending on which area of the brain was damaged, as well as how much damage occurred, a stroke can impact a person’s ability to move, see, feel, speak, understand and remember.
