What is stroke?
A stroke occurs when the blood supply to part of the brain is suddenly interrupted or when a blood vessel in the brain bursts, spilling blood into the spaces surrounding brain cells. Brain cells die when they no longer receive oxygen and nutrients from the blood or there is sudden bleeding into or around the brain. The symptoms of a stroke include:
- sudden numbness or weakness, especially on one side of the body;
- sudden confusion or trouble speaking or understanding speech;
- sudden trouble seeing in one or both eyes;
- sudden trouble with walking, dizziness, or loss of balance or coordination;
- or sudden severe headache with no known cause.
