What is a common sign of a stroke?

A common sign of a stroke is sudden numbness or weakness in one side of the body. This is often indicative of a disruption in blood flow to the part of the brain responsible for motor control and sensation. When a stroke occurs, it can affect the left side of the brain, leading to numbness or weakness on the right side of the body, or vice versa. Recognizing this sign is critical for prompt medical intervention, which can significantly improve recovery outcomes.

While other options such as sudden headaches, difficulty breathing, and blurry vision can also be associated with various medical conditions, they are not as specific or universally recognized as acute symptoms of stroke as sudden numbness or weakness. The focus on one side of the body is a key characteristic that separates stroke symptoms from other potential health issues.
