A stroke occurs when blood flow is blocked to a part of the brain. Brain cells become deprived of oxygen and begin to die. As brain cells die, people experience weakness or paralysis, and some lose the ability to speak or walk.
In the United States, a stroke happens every 40 seconds, according to the American Stroke Association (ASA). It’s the leading cause of disability. The road to recovery can be lengthy and unpredictable, so it’s important to understand the risk factors of a stroke and how to prevent them from happening.
