Ischemic stroke occurs as a result of an obstruction within a blood vessel supplying blood to the brain. It accounts for 87 percent of all stroke cases.
Hemorrhagic stroke occurs when a weakened blood vessel ruptures. Two types of weakened blood vessels usually cause hemorrhagic stroke: aneurysms and arteriovenous malformations(AVMs). But the most common cause of hemorrhagic stroke is uncontrolled hypertension (high blood pressure).
TIA (Transient Ischemic Attack)
TIA (transient ischemic attack) is caused by a temporary clot. Often called a “mini stroke”, these warning strokes should be taken very seriously.
