Ischemic stroke occurs when a blood clot blocks or narrows an artery leading to the brain. Blocked or narrowed blood vessels are caused by fatty deposits that build up in blood vessels or by blood clots or other debris that travel through your bloodstream and lodge in the blood vessels in your brain.
Also to know is, what is the major cause of cerebrovascular accidents?
Cerebrovascular disease can develop from a variety of causes, including atherosclerosis, where the arteries become narrow; thrombosis, or embolic arterial blood clot, which is a blood clot in an artery of the brain; or cerebral venous thrombosis, which is a blood clot in a vein of the brain.
Similarly, what is a ischemic cerebrovascular accident? Cerebrovascular accident: The sudden death of some brain cells due to lack of oxygen when the blood flow to the brain is impaired by blockage or rupture of an artery to the brain. A CVA is also referred to as a stroke. Symptoms of a stroke depend on the area of the brain affected.
Furthermore, what is the most common cause of ischemic stroke?
Ischemic stroke can be caused by several different kinds of diseases. The most common problem is narrowing of the arteries in the neck or head. This is most often caused by atherosclerosis, or gradual cholesterol deposition. If the arteries become too narrow, blood cells may collect and form blood clots.
What are the two main direct causes of a cerebrovascular accident?
There are two main types of cerebrovascular accident, or stroke: an ischemic stroke is caused by a blockage; a hemorrhagic stroke is caused by the rupture of a blood vessel. Both types of stroke deprive part of the brain of blood and oxygen, causing brain cells to die.

How does cerebrovascular accident affect the nervous system?
When a stroke occurs, nerve cells in the brain tissue become injured. As a result of this injury, nerve cells cannot communicate with other cells, and functions are impaired. If a stroke occurs on the right side of the brain, the left side of the body is affected, and vice versa.
