Ischemic stroke is a serious medical condition that occurs when blood flow to a part of the brain is blocked or reduced, depriving brain cells of oxygen and nutrients. This interruption in blood supply can lead to permanent brain damage, disability, or even death if not treated promptly. It is the most common type of stroke, accounting for nearly 85% of all stroke cases worldwide.
The primary cause of ischemic stroke is the obstruction of blood vessels supplying the brain. This blockage often results from a blood clot (thrombus) forming in a brain artery or a clot traveling from another part of the body, such as the heart, to the brain (embolism). Conditions like atherosclerosis, which leads to the narrowing and hardening of arteries, significantly increase the risk of developing ischemic stroke. Other contributing factors include high blood pressure, diabetes, high cholesterol, smoking,…
