Stroke is the rapid loss of brain functions when there is an interruption of the blood supply to the brain. It can be due to ischemia caused by blockage, or a hemorrhage. Ischemic stroke currently accounts for 80 percent of all strokes.

It is important for people to recognize the early signs of stroke and seek immediate treatment without delay.

All strokes happen fast, and symptoms appear suddenly. It's common for people to get more than one symptom at the same time, though not everyone gets all of the signs.

These are the signs to watch out for:

Sudden numbness or weakness of the face, arm or leg, especially on one side of the body.

Sudden confusion, trouble speaking or understanding.

Sudden trouble seeing in one or both eyes.

Sudden trouble walking, dizziness, loss of balance or coordination.

Sudden severe headache with no known cause.
