A stroke is characterized by significant disruption of the blood flow to the brain which may lead to a decrease in the incoming blood supply. When this happens the brain tissue will be deprived of oxygen and the necessary nutrients. After short while, brain cells will be progressively killed. The brain is a very complex organ controlling the entire body functions and senses. Any disruption with the brain will cause the other areas of the body to function erratically or cease to function.

If the cerebellum is involved, you may have loss of coordination and balance. If the TIA occurs at the base of the brain, you may have drop attacks, where you suddenly fall or lose consciousness. If the occipital lobe is affected, you will experience sudden loss of vision or blurred vision.

Many people suffer emotional disturbances after a stroke, even a mild one. They can become emotionally labile, for example laughing or crying at inappropriate times. This can be very distressing both for the person and their carers, family or relatives. According to neurologists, if a stroke can be immediately recognized and medial attention made available within three hours, it is normally possible to reverse the effects, often completely. The problem is that strokes are often unrecognized since most people are unaware of the symptoms. But when the brain stops functioning completely - brain death - the other organs have nothing control them and gradually die also.

Among patients who survive a stroke there is usually some improvement in the first month and the extent of this improvement can be a guide to expected future improvement. The brain is an amazingly adaptable organ. While dead brain cells can never recover, partly damaged ones may make a partial recovery over time. If you or someone you know has one or more of these symptoms you need to act fast. Stroke damage occurs when the blood flow is cut off from the brain. In addition to recognizing the symptoms, it is important to be proactive in your life and do your best to prevent a stroke before it ever happens. If you are in the high risk category you need to reverse your lifestyle.

symptoms to appear within seconds, whereas a narrowed artery will take minutes, hours, or maybe even days to appear. If any of the symptoms of strokes mentioned above suddenly appear, emergency medical response should be sought. The affected person should lie flat to promote an optimal blood flow to the brain.
