Of course, in this day and age, with technology making a popular vote of the President much more practical, many people advocate the abolishment of the Electoral College. They argue that the popular vote should elect the President, rather than the people who elect the President.
Lack of blood flow to the brain, from blood clots or broken blood vessels, causes a stroke. In some cases, bleeding in the brain can also cause a stroke. Without a good blood supply, brain cells cannot get enough oxygen and begin to die. (Source: excerpt from HEART AND CARDIOVASCULAR DISEASE: NWHIC)
TIA (Transient Ischemic Attack). Ischemic stroke occurs as a result of an obstruction within a blood vessel supplying blood to the brain. It accounts for 87 percent of all stroke cases. Hemorrhagic stroke occurs when a weakened blood vessel ruptures. Two types of weakened blood vessels usually cause hemorrhagic stroke: aneurysms and arteriovenous malformations (AVMs). But the most common cause of hemorrhagic stroke is uncontrolled hypertension (high blood pressure). TIA (transient ischemic attack) is caused by a temporary clot.
