Ischemic Stroke: Understanding Causes, Symptoms, and Prevention
Ischemic stroke is the most common type of stroke, occurring when a blood clot or blockage restricts blood flow to the brain. This interruption prevents oxygen and nutrients from reaching brain cells, leading to potential damage within minutes. Common causes include atherosclerosis (narrowing of arteries), high blood pressure, diabetes, smoking, and high cholesterol levels.
Symptoms often appear suddenly and may include weakness or numbness on one side of the body, difficulty speaking, blurred vision, dizziness, and loss of coordination. Recognizing these warning signs early is critical, as immediate medical intervention can significantly reduce long-term complications. Quick response treatments, such as clot-dissolving medications or mechanical clot removal, can help restore blood flow and improve recovery outcomes.
