What is an ischemic stroke?

An ischemic stroke occurs when blood flow to a part of the brain is blocked, typically due to a blood clot or a buildup of fatty deposits in the arteries, known as atherosclerosis. This blockage prevents oxygen and nutrients from reaching brain cells, leading to cell damage or death if not resolved quickly.

Recognizing the characteristics of an ischemic stroke is crucial for prompt treatment, as restoring blood flow is essential to minimizing brain damage and preserving neurological function. The focus on blood flow blockage distinguishes ischemic strokes from other types of strokes, such as hemorrhagic strokes, which involve bleeding inside or around the brain.

Understanding this definition helps provide clarity on the nature of ischemic strokes and emphasizes the importance of addressing blood flow disturbances in the brain to mitigate their serious consequences.
