Can the old age predicted dull-wittedly through the instrument?
Can the old age predicted dull-wittedly too? The strong American scientist works out the new scientific and technological products again, it is said that can predict the dull-witted morbidity possibility of old age.The editor recommends:The old man often walks Help, prevent old age from to be dull-wittedThe researchers of Chicago of U.S.A. develop a kind of screening tool newly, the elderly over the prediction 65 that it can be accurate suffer from the possibility of senile dementia within 6 years.
Researchers will suffer from the risk cause of senile dementia through the overview ' Such as taking action and thinking is slow,etc.) List one by one, through testing and the result analyzes, assess out the possibility to suffer from senile dementia finally. This test has gone through 6 years, has predicted out half senile dementia case, this result of study was issued on the " neurology " magazine recently.
The statistics show, nearly there are 26 million senile dementia patients in the whole world, and senile dementia is the main form of dementia. It is confused that senile dementia comes from slight consciousness lose or consciousness, upgrade to and totally lose consciousness and not take care of oneself finally.
The researcher Deborah Barnes of University of California says: "The help doctor who a technology that can predict the senile dementia risk can be effective observes patients, help the pharmaceuticals to develop the new medicine, treat the patient that does not lose as the early brain function of treating the measure effectively at present. " Barnes says: "This kind of risk index not merely contributes to preventing and studying senile dementia, and very important to suffering from old man of senile dementia and their relative. "
This tests newly that not merely considers some common having the characteristic of senile dementia risk, for instance advanced age, gene correlated to senile dementia,etc., and consider the risk factor that some people seldom find out about, if weight, get drunk of patient used to, make heart bypass surgery, make some simple physical sport ' Such as stitching a button) Whether take action and wait a moment slowly hour. Test, carry on 15 make to the intersection of risk and characteristic, test results low thinking have ApoE4 genes increase the hereditary danger of senile dementia. If the test result is 8 points or more than 8 points, this shows and suffers from senile dementia during the following 6 years very riskily.
In order to improve this index, the research group surveys 3375 old men, their mean age is 76 years old, have not suffered from senile dementia. 6 years later, 480 people among them suffer from senile dementia. Subsequently, researchers continue carrying on research to the factor of senile dementia, think through which factors the finding can reflect people who got senile dementia most.
As they evaluate overview to find, suffer from senile dementia in the next 6 years for the old man of the high score in 56% of the test results among them, and it accounts for 23% in the ill number of old man of section of the middle to divide several, the ill number of people of obtaining lesser value accounts for 4%.
Generally speaking, this index has made the correct classification for 88% of the participants. Barnes shows, index of this risk still needs to be further verified. Her group will continue studying too, will find more rational and simpler explanation.
