Understanding Ischemic Stroke: Causes, Symptoms, and Emerging Treatments
Ischemic stroke is one of the leading causes of death and long-term disability worldwide, accounting for nearly 85% of all stroke cases. It occurs when the blood flow to a part of the brain is obstructed, depriving brain tissue of oxygen and nutrients. Within minutes, brain cells begin to die, making immediate medical attention critical. Despite the devastating impact, advances in medical technology, preventive care, and rehabilitation have improved outcomes for stroke patients significantly over the past decade.
Causes and Risk Factors
The primary cause of an ischemic stroke is a blockage in an artery that supplies blood to the brain. This blockage can be due to a thrombus (blood clot) forming within a brain artery or an embolus, a clot that forms elsewhere in the body and travels to the brain. Common conditions that increase the risk include atherosclerosis, where fatty…
