A stroke is sometimes called a "brain attack." Most often, stroke occurs when blood flow to the brain stops because it is blocked by a clot. The brain cells in the immediate area begin to die because they stop getting the oxygen and nutrients they need to function. Although doctors can sometimes intervene to reduce stroke damage, in many cases the brain cells served by these blood vessels become starved and begin to die off. After the stroke, the resulting damage may impair behavior or body functions controlled by the affected parts of the brain. There are two kinds of stroke. The most common kind of stroke, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind of stroke, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. Stroke damage in the brain can affect the entire body - resulting in mild to severe disabilities. These include paralysis, problems with thinking, problems with speaking, and emotional problems.

a stroke or CVA, cardiovascular accident is where there is a blockage of blood to the brain thru the carotid arteries. a MI, is a myocardial infarction where blood flow is obstructed with the heart.
When a person has a stroke or CVA it damages the lobe of the brain effected by the blocked carotid artery or smaller arteries in the brain; as in right or left sided. The result being weakness or immobility of the opposite side of the body. Example=right sided CVA effects the left side of the body and vice versa. They usually will have limited orientation to who, where, when and be confused. After they are stabilized, the patient will begin a rehab program to adapt to life with the lingering effects of the stroke.
There is a med in the ER's now, that if you can get a patient in immediately after the stroke, that will bust the clot and improve the patient prognosis significantly.

a stroke is the result of decreased bloodflow to the brain. It can be caused by a blocked or clotted artery, as well as an anuerism (bursting of a blood vessel).
Due to the makeup of the brain and the circulatory system that supplies it blood, it's not uncommon for only one side of the brain to be effected by stroke. That's why one of the signs of stroke is sagging/drooping/decreased function on just one side of the body.
The results of a stroke can range from brief symptoms that go away on their own (some very minor strokes aren't even noticed for what they are... people literally 'walk them off', so to speak), to coma and death. Once again, due to the complexity of the brain, the results of a stroke are very unpredictable.
The same problems that set one person up for heart failure (narrowing of the blood vessels) also set one up for strokes.

A stroke is when a clot of blood forms in a vein a piece of the clot breaks away and hits the brain causing a stroke,It is nothing to do with the heart..

A stroke, also known as cerebrovascular accident (CVA),[1] is an acute neurological injury in which the blood supply to a part of the brain is interrupted. That is, a stroke involves the sudden loss of neuronal function due to disturbance in cerebral perfusion. This disturbance in perfusion is commonly arterial, but can be venous.
It has to do with an injury in the brain as a result of a blood clot or burst vessel cutting off oxygen to the brain.

A stroke is refered to as a "brain attack". A stroke
occurs when blood flow to the brain is stopped,
usually by a blood clot. It is very serious.

From Wikipedia:
The term "brain attack" is starting to come into use in the United States for stroke, just as the term "heart attack" is used for myocardial infarction, where a cutoff of blood causes necrosis to the tissue of the heart. Many hospitals have "brain attack" teams within their neurology departments specifically for swift treatment of stroke.

A stroke is when a large vein or artery bursts in the brain, like a brain aneurysm.

you could have a stroke when you have high blood pressure & you are not taking anything for it. If you have headaces or your cheeks are red you should get checked out by a doctor.A stroke itself is when a blood vessel breaks in the brain.Sometimes you lose use of your left side of your body.Sometimes you regain the useage sometimes you don't depending on how serious the stroke was.I have high blood pressure & i'm on 3 pills a day so I know what I'm talking about...If you have any symptions please get it checked out.
