What are the causes of the obstruction of blood flow to the brain?
Obstruction in the blood flow to the brain maybe caused by clogging of the blood vessels due to fatty deposits or by a wandering blood clot that forms outside the brain and is then carried to the brain in the blood stream. This clot may plug the blood vessels. A weak point in a blood vessel or high blood pressure may cause a rupture of a blood vessel in the brain, resulting in Stroke.
