Understanding Ischemic Stroke: Causes, Symptoms, and Prevention
Ischemic stroke is one of the most prevalent forms of stroke, occurring when a blood clot or other obstruction blocks blood flow to a part of the brain. This interruption in circulation deprives brain tissue of oxygen and nutrients, causing cells to die within minutes. Prompt medical attention is critical, as timely intervention can significantly reduce long-term damage and improve recovery outcomes.
Causes of Ischemic Stroke
The primary cause of ischemic stroke is the obstruction of blood vessels supplying the brain. This can happen due to:
Thrombosis: Formation of a blood clot within one of the brain’s arteries, often due to atherosclerosis, where fatty deposits narrow the vessels.
