Stroke occurs due to a decrease in oxygen to the brain. A bleed or blockage in the brain’s blood supply can cause it. Immediate emergency treatment may help prevent life-threatening consequences.
A stroke is your brain’s equivalent of a heart attack, happening when there’s an issue with blood flow to part of your brain. This can happen when blood vessels are blocked or because of bleeding in your brain. Strokes are a life-threatening emergency, and immediate medical attention is critical to prevent permanent damage or death.
