A thrombus is caused by the build-up of fatty deposits in the artery walls, causing the artery to become narrower therefore reducing the blood flow. Eventually the artery becomes completely blocked restricting the blood from reaching the brain. This causes the functions controlled in the area where the stroke attacks to be damaged or die.
