A stroke can occur when poor blood flow to the brain causes cells to die. It is the fifth leading cause of death in America and the leading cause of disability. There are two types of stroke: ischemic, which results from narrowing or blockage of the arteries leading to the brain, and hemorrhagic, which results from decreased blood flow.
When a blood vessel carrying nutrients to the brain ruptures or is blocked by a clot, part of the brain can’t get the blood and oxygen it needs to function, causing cells to die. The brain is a complex organ that controls many functions in the body. So when a stroke occurs and blood flow to a specific part of the brain is reduced, a part or parts of the body not controlled by the affected part of the brain are able to function properly.
