Types of Ischemic Stroke
There are two types of ischemic stroke:
- Thrombotic strokes, which are caused by a blood clot that forms in an artery that supplies blood to your brain.
- Embolic strokes. They happen when a clot forms somewhere else in your body and travels through the blood vessels to your brain. It gets trapped there and stops the flow of your blood.
Causes
Most Ischemic Strokes are caused by atherosclerosis. Besides atherosclerosis, some other causes of ischemic stroke are:
- Irregular heartbeat

- Problem with your heart's valves
