Study Notes
- Ischemic strokes are caused by a lack of oxygen in vital tissues, most commonly due to a blood clot.
- Thrombotic stroke is the most common type of ischemic stroke, and it usually occurs when an artery to the brain is blocked by a thrombus.
- Embolic stroke is the second most common type of ischemic stroke, and it occurs when a blood clot lodges in an artery in the brain.
- Lacunar stroke is a type of ischemic stroke that is caused by small vessel strokes.
- Transient ischemic attacks are mini-ischemic strokes that typically occur due to tiny emboli.
- Most symptoms of ischemic stroke resolve within a day, but a transient ischemic attack is often considered to be a warning signal of an ischemic stroke.
