What artery is mostly affected in stroke?
The middle cerebral artery (MCA) is the most common artery involved in stroke. It supplies a large area of the lateral surface of the brain and part of the basal ganglia and the internal capsule via four segments (M1, M2, M3, and M4).
Do different types of strokes have different symptoms?
The different stroke types cause similar symptoms because each affects blood flow in your brain. The only way to determine what type of stroke you may be having is to seek medical attention.

- Loss of ability to understand or express speech.
When is a stroke not a stroke?
A transient ischemic attack has the same origins as that of an ischemic stroke, the most common type of stroke. In an ischemic stroke, a clot blocks the blood supply to part of your brain. In a transient ischemic attack, unlike a stroke, the blockage is brief, and there is no permanent damage.
What is considered a mild stroke?
Mild strokes are usually quick, occurring when there is a brief blockage of blood flow to the brain. Mild stroke symptoms are similar to those of a regular stroke but last for only a few minutes up to 24 hours. People who experience a mild stroke shouldn’t ignore the symptoms and need to seek immediate medical help.
What is ICA stroke?
A complete occlusion of the internal carotid artery (ICA) is an important cause of cerebrovascular disease. A never‐symptomatic ICA occlusion has a relatively benign course, whereas symptomatic occlusion increases future risk of strokes.
