Stroke is a disease affecting the blood flow to and through your brain. A stroke occurs when a blood vessel carrying oxygen and nutrients to the brain is blocked by a clot or the vessel ruptures. As a result, your brain, or a section of it, cannot get the blood and oxygen it needs. If it is not treated quickly, brain cells and tissues needed to maintain your body’s functions and movement can die.
