In the last week, an analysis was presented in “International Stroke Conference” of the “American Stroke Association”.  That was a little study what adds the further proof to what the most of sleep experts know already - that “Obstructive sleep apnea” or OSA is actually linked with the high level of risk of getting the silent strokes.

OSA or Obstructive Sleep Apnea is very much common appearance of the sleep apnea, in line with the organization of “National Institutes of Health”.  In excess of twelve million Americans now are believed in suffering from this type of sleep disorder. Many of the people with the sleep apnea generally stop breathing just for ten  to twenty  seconds or else longer than that and it  can cause in any case twenty  to thirty times in one hour.

In the new study, the researchers at the Dresden University which is in Germany, normally looked at the silent strokes as well as the occurrence of the OSA in fifty six patients who actually had been then hospitalized for the major stroke. Now, what is the major difference between this kind of stroke and the silent stroke?  Usually the silent strokes are detected only by imaging brain with the  MRI or/and CT scan what can show the areas of that damage even if the attacked person was actually not that much aware of the obvious neurological shortfall at that time of scarring.

The silent stroke has been linked with the increase risk just for the major stroke. As a result, if people can establish in addition to eliminate all the risk factors only for the silent stroke, hypothetically, all of the people can avoid the risk of having major strokes what can kill as well as disable. Moreover, the stroke victim in that study was then broken into the two groups: People of those who actually had the confirmation of the silent strokes plus those who normally did not.  Then they also looked at all those victims who had the evidence of the chronic damages to the little blood vessel in brain plus those who actually did not.  The researchers actually tried to observe if the OSA was common in those people with the silent stroke as well as with the chronic vascular break. 91%   of the patients of the study had the OSA or obstructive sleep apnea, this was identified by the test on overnight sleep.
