As a medical professional with expertise in neurology, I can provide insight into the causes of ischemic stroke. The most common cause of ischemic stroke is a thrombotic stroke, which occurs when a blood clot (thrombus) forms within an artery that supplies blood to the brain. This clot blocks the flow of blood, leading to ischemia, which is the reduction of blood supply to a part of the body, in this case, the brain. Other causes of ischemic stroke can include embolic stroke, where a clot forms elsewhere in the body and travels to the brain, or systemic conditions that affect blood flow, such as atrial fibrillation. read more >>
