A stroke is the sudden onset of a sudden, painful loss of blood.
The most common cause of stroke is a blood clot.
The clot forms on a white, hard clot, called a pericardium.
A clot forms if a clot from a vein or artery is not properly blocked or blocked completely.
Strokes can be life-threatening and can be deadly.
People who are at higher risk for stroke are people who have: had a heart attack, stroke or a heart failure
