What type of stroke occurs due to blocked arteries?

The type of stroke that occurs due to blocked arteries is known as an ischemic stroke. This condition arises when there is a disruption in blood flow to a part of the brain, typically caused by a blockage in the arteries that supply blood to that region. The blockage can be due to a blood clot or the narrowing of arteries, often related to atherosclerosis—a buildup of fatty deposits in the artery walls.

Ischemic strokes account for the majority of all strokes, making it critical to recognize the symptoms early for timely treatment. The brain cells receive insufficient oxygen and nutrients as a result of the disrupted blood flow, leading to potential brain damage.

Other types of strokes, such as hemorrhagic strokes, occur due to ruptured blood vessels rather than blockages. Transient strokes, often referred to as transient ischemic attacks (TIAs), are temporary and do not result in permanent damage, while cardiac strokes typically refer to those stemming from heart-related issues, which could lead to embolic strokes but are not classified in the same category as ischemic strokes.
