Ischemic Stroke (Clots): Occurs when a blood vessel supplying blood to the brain is obstructed. It accounts for 87 % of all strokes.
Hemorrhagic Stroke (Bleeds): Occurs when a weakened blood vessel ruptures. The two types of weakened blood vessels that usually cause hemorrhagic stroke are aneurysms and arteriovenous malformations (AVMs). The most common cause of hemorrhagic stroke is uncontrolled high blood pressure.
TIA (Transient Ischemic Attack): Called a mini-stroke, it’s caused by a serious temporary clot. This is a warning sign stroke and should be taken seriously.
Cryptogenic Stroke: In most cases, a stroke is caused by a blood clot that blocks the flow of blood to the brain. In some instances, despite testing, the cause of a stroke can’t be determined. This is called a cryptogenic stroke.
