“Ischemic stroke is to the brain what a heart attack is to the heart. In fact, it is sometimes referred to in layman’s terms as a “brain attack.” It is commonly caused by atherosclerosis, or hardening of the arteries, which results from a build up of fat, cholesterol, calcium and other substances that leave little space for blood flow. This is known as a thrombosis. When the thrombosis clogs the already narrow passage, an ischemic stroke occurs, resulting in the death of brain cells in the area deprived of blood. It can also be caused by a blood clot that travels to the brain from another part of the body, which is a type of ischemic stroke known as an embolism.

Hemorrhagic stroke, on the other hand, occurs when a weakened artery in the brain bursts, causing bleeding within the brain that is often very difficult to manage. The weakened artery walls that are a hallmark of this condition are typically the result of uncontrolled high blood pressure or an aneurysm.”
