Stroke occurs due to a decrease in oxygen to the brain. A bleed or blockage in the brain’s blood supply can cause it. Immediate emergency treatment may help prevent life-threatening consequences. Stroke is the fifth leading cause of death in the world. In fact, nearly 800,000 people have a stroke each year. That equates to around one person every 40 seconds.

There are three main types of stroke: Ischemic Stroke: This is the most common type of stroke, making up 87% of all cases.
A blood clot prevents blood and oxygen from reaching an area of the brain.

Hemorrhagic Stroke: This occurs when a blood vessel ruptures. These are usually the result of aneurysms or arteriovenous malformations (AVMs).

Transient Ischemic Attack (TIA): This occurs when blood flow to a part of the brain is inadequate for a brief period of time. Normal blood flow resumes after a short amount of time, and the symptoms resolve without treatment. Some people call this a ministroke.
