Beware of silent stroke
What if a stroke had attacked someone, but did not realize it? If you've never heard the term silent stroke, you are not alone. Scientists have also recently realized the importance of vigilance against the presence of these silent strokes.

Although the term silent is a bit wrong, but the title is out because of brain regions that have suffered a stroke does not cause a change in one's motor functions. That is, do not cause paralysis, speech dysfunction, pain, or even a touch of flavor disturbance.

Symptoms are subtle at all. So most people think aging is normal and nothing to do with brain damage resulting from stroke. For example, associated with the function of thinking, remembering, and the atmosphere, so the symptoms are difficult to detect silent stroke. In addition to functions related to thinking earlier, other symptoms of silent stroke is decreased balance, loss of bladder control, mood and personality changes, and loss of cognitive abilities. All of that also includes the most common symptoms of the disease in the elderly. So this is where the word 'silent' is present, which makes the patient did not realize it.

So, what exactly is a silent stroke? He is the blockage of small blood vessels, deep in the brain that cause real damage, but do not show obvious symptoms. Therefore, the stroke in this region is called as silent.

Silent strokes occur in the brain depends on a single small blood vessels to get oxygen and nutrients flow. This brain area, said Silvia, such as frontal cortex and white substansia located deeper. Because of a lack of blood flow, then the alternative route had blocked the withdrawal of small vessels
Globally, about ten percent of middle-aged healthy people estimated to have a silent stroke without realizing it. And he is almost five times more often than usual clear stroke symptoms. In the United States alone, every year about 11 million people are estimated to have experienced a silent stroke. Healthy people usually do not think they might have a little silent stroke. As a result, millions of people literally do not know they have had a stroke.

It is recommended that the community has a consciousness and awareness of this silent stroke. Because people who've been there, at higher risk for subsequent stroke, and will experience a rapid decline in cognitive skills abilities. Silent stroke may also increase the likelihood of stroke is more serious and ultimately fatal.
