The brain is the commander center of the body that controls virtually all bodily functions, from breathing to the beating of our hearts to our ability to think and speak .

Like other organs of the body, the brain requires a steady flow of blood and oxygen to function normally. When the supply of blood and oxygen is impaired, it can cause a stroke, a sudden malfunction of the brain. If oxygen levels in the brain drop low enough, there can be permanent neurological damage.

Not all strokes are the same. some are so slight the victim may not even be aware he is having one. In some cases, the person experiencing a stroke may simply feel a slight numbness in his face or arm, or may have difficulty speaking or thinking clearly for a brief period of time. For other people, the stroke is so devastating that it can cause permanent paralysis or even death.

Although all strokes are a result of the reduction in blood flow to the brain, that trigger is not always set of by the same thing. Common causes of stroke include atherosclerosis, blood clots, hemorrhage, and aneurysms.

Atherosclerosis, or the narrowing or blockage of an artery due to fatty deposits, accounts for slightly more than half of all strokes. With proper diet, the right supplements, and a healthy lifestyle, atherosclerosis is a preventable disease.

In some cases, a stroke will occur if the artery delivering blood to the brain becomes blocked by a blood clot. There are several supplements that can help to prevent blood clots.

In addition, a weakening in the cerebral artery, called an aneurysm, could cause an artery to break, thus causing a hemorrhage. Although some aneurysms are genetic, maintaining normal blood pressure can help to prevent arterial weakness that can lead to the formation of an aneurysm. Not smoking also substantially decreases your risk of both aneurysm and stroke.

In many cases, however, strokes can e avoided simply by preventing the underlying medical conditions that leave us vulnerable to them.
