A stroke—a decrease in blood flow to the brain due to a clot or bleeding—is a medical emergency. And doctors often say “time is brain,”. So don’t waste time wondering if you should go to the hospital. If you or someone you know has the following symptoms, call 911.
Trouble seeing or blurry vision. Stroke can cause double vision, blurred vision or loss of vision in one eye. But it may not be as well recognized as facial weakness, arm weakness, and speech problems.
