Stroke is a condition characterized by reduced blood flow to the brain. It is also known as a cerebrovascular accident or cerebrovascular insult.
Ischaemic strokes are the most common form of stroke, accounting for 80-90% of strokes overall. They are when the blood flow is obstructed by a blood clot, they can be caused by atherosclerosis (which causes 15-25% of strokes overall, they are usually large-artery strokes) or they can be clots from the heart that travel up into the brain (cardioembolic strokes, accounting for 14-30% of ischaemic strokes) and small-vessel strokes (accounting for 19-33% of strokes overall).
