Understanding Ischemic Stroke: Causes, Symptoms, and Prevention
Ischemic stroke is one of the most common types of stroke, occurring when a blood clot or other obstruction blocks blood flow to a part of the brain. Unlike hemorrhagic stroke, which involves bleeding in the brain, ischemic stroke results from a lack of oxygen and nutrients due to interrupted blood circulation. This deprivation can quickly damage brain cells and lead to long-term neurological impairments if not treated promptly.
The primary cause of ischemic stroke is the formation of blood clots in the arteries supplying the brain. These clots can develop in the arteries themselves, known as thrombotic strokes, or travel from other parts of the body, such as the heart, in which case they are called embolic strokes. Conditions like atherosclerosis, where the arteries become narrowed due to plaque buildup, significantly increase the risk of clot formation. Heart diseases, high blood pressure,…
