A stroke is a medical emergency that occurs when the blood supply to part of the brain is disrupted, either by a blood clot blocking a blood vessel or by a blood vessel breaking and bleeding into the brain. This disruption in blood flow can cause brain cells to die, leading to various symptoms depending on the area of the brain affected.

The most common symptoms of a stroke include:

• Sudden numbness or weakness in the face, arm, or leg, especially on one side of the body
• Sudden confusion or difficulty speaking or understanding
• Sudden difficulty seeing in one or both eyes
• Sudden difficulty walking, dizziness, or loss of balance or coordination
• Sudden severe headache with no known cause

If you suspect that someone is experiencing a stroke, it is important to seek emergency medical attention immediately. The sooner a person receives treatment for a stroke, the better their chances of recovery.
