Why is stroke considered as a dangerous act?

A healthy life is vital if you want to achieve a lot in your lifetime. Whatever you eat and drink will affect the well being of your body. Aside from facing the daily challenges of work, you have to be on constant guard against diseases, adverse health conditions, and accidents. Stroke, also called brain attack, is one of the deadliest medical conditions. For this reason, it is considered a dangerous act.

The World Health Organization defines stroke (http://www.who.int/topics/cerebrovascular_accident/en/) as a Cerebrovascular accident, which means that it is “…caused by the interruption of the blood supply to the brain, usually because a blood vessel bursts or is blocked by a clot.” This leads to brain tissue damage or brain cell deaths as a consequence of the brain’s supply of oxygen and nutrients being cut off. When blood flow to the brain stops, brain cells begin to die within minutes. Stroke will eventually follow.

According to The Stroke Center (http://www.uhnj.org/stroke/stats.htm) at University Hospital in Newark, New Jersey, stroke is the second leading cause of death in the world. Each year, about 4.4 million or 9 percent of the total 50.5 million deaths are due to stroke. Over the course of a lifetime, four out of five families will experience stroke.

A stroke can be caused by an obstacle in the flow of blood, such as a blood clot lodged in a blood vessel or traveling debris in the bloodstream. A sudden rupture of an artery that feeds blood to the brain may also cause stroke. A reduction of blood flow to all parts of the body or a locally increased venous pressure, as well as intracerebral hemorrhage due to hypertension can result to stroke.

There are two kinds of stroke. The first and more common kind is the ischemic stroke, which is caused by a blood clot that obstructs a blood vessel in the brain. The second kind is the hemorrhagic stroke, which is caused by a blood vessel that breaks and then bleeds in the brain.

How do you detect a stroke? Symptoms of strokes normally start suddenly in over a second to a couple of minutes. The common symptoms include the following:

Your face, arm, or leg suddenly becomes numb or weak. This happens particularly on one side your body.
You suddenly become confused. You have trouble speaking or understanding any conversation.
You suddenly have trouble seeing in one or both eyes.
You suddenly have trouble walking. You feel dizzy, lose balance or coordination. You may also suddenly faint or lose consciousness.
You feel severe headaches with no particular cause.

The effects of stroke to your body depend on two things: Which part of the brain is injured and how severe the damage is. Some people survive multiple strokes over a period of time. A severe stroke may prove lethal since it may lead to sudden death. To read more about stroke, do a visit site to the WHO website and follow it with more research.
