Www.xinhuanet.com Los Angeles 4 Cable of the 6th of moon (reporter's plateau) U.S.A.'s latest research reveals, the technology of nuclear magnetic resonance imaging of use scans brain, can help doctor predict cognitive the intersection of obstacle and patient in the future can suffer from the intersection of Alzheimer and disease slightly ' Degenerative brain disorder) . The researchers of San Diego medical college of University of California write articles and say on the magazine network edition of " radiology " on the 6th, scan the result to analyze the nuclear magnetic resonance brain, can calculate slightly the cognitive obstacle patient suffers from Alzheimer's risk of disease within one year. The data are collected between 2005 and 2010, including the initial nuclear magnetic resonance scans the result and check situation after one year. Study and involve 203 healthy adult, 317 cognitive obstacle patient and 164 sending disease patient Alzheimer late slightly. The mean age of the research object is 75 years old. Researchers analyze and compare with inspection results of the nuclear magnetic resonance two times, then calculate slightly the cognitive obstacle patient develops into Alzheimer's risk of disease. Researchers point out, through the brain scanning of the nuclear magnetic resonance, can find the degradation situation of the cognitive obstacle patient's brain cerebral cortex slightly, thus judge that suffers from Alzheimer's risk of disease. The cerebral cortex plays a key role in memory, attention, thinking and language, and Alzheimer, one of the characteristics of disease is that the cells of some positions of cerebral cortex disappear, lead to the fact this position shrinks. The cognitive obstacle means slightly people present slight memory or other cognitive function obstacles, but not reached the dull-witted standard, its clinical manifestation not only has memory obstacle, but also attention, word are smooth, obstacle of other cognitive functions of carrying out ability etc.. The cognitive obstacle might not be developed into Alzheimer's disease, but increase with age slightly, it is more serious than normal people that the patient presents the situation that intelligence fails.
