Customer question:
What is ischemic stroke? Anonymous customer's question
Pharmacist's answer:
Ischemic stroke is a type of stroke that occurs due to an interruption of blood flow to a specific part of the brain. This interruption is usually caused by a blockage or blockage of an artery that supplies blood to the brain.
Ischemic stroke is much more common than hemorrhagic stroke, which occurs due to bleeding in the brain.
The cause of an ischemic stroke is often the formation of a blood clot (thrombus) in an artery of the brain, or a clot forms elsewhere in the body (for example, in the heart) and travels to an artery of the brain (embolism). There are two main types of ischemic strokes:
- Thrombotic stroke occurs when a thrombus (clot) forms in an artery that supplies blood to the brain. It usually appears in a place where the artery has already been narrowing due to atherosclerosis.
- An embolic stroke occurs when a thrombus forms elsewhere in the body (e.g., in the heart) and travels to an artery in the brain, where it causes a blockage of blood flow.
Ischemic stroke symptoms depend on which part of the brain is affected. Some common symptoms include sudden numbness or weakness on one side of the face, arms, or legs, difficulty walking, difficulty speaking and understanding speech, dizziness, vision problems, severe headaches, etc.
