The emergence of analysis is capable of diagnosing the disease years before the onset of symptoms, will give patients the opportunity to take countermeasures.
A new blood test, developed by an international team of scientists allows to diagnose Alzheimer’s disease long before first symptoms. Reported by the New Atlas.
Scientists believe that deposits of beta-amyloid, or plaques in the brain, the most likely cause of Alzheimer’s disease. A new blood test measuring their concentration.
The amyloid plaques formed in the brain slowly over 10 – 20 years before the surface are the first symptoms, e.g. memory loss.
Modern tests on beta-amyloid – time consuming, expensive and invasive procedure, which includes expensive positron emission tomography, or analysis of cerebrospinal fluid obtained through lumbar puncture.
A new blood test, developed by a group of scientists from Japan and Australia, was tested on several hundred patients and was able with 90% accuracy to predict the high content of beta-amyloid in the brain.
“Taking a tiny drop of blood, we can, thanks to a new method to measure multiple proteins associated with amyloid, despite the fact that their concentration is extremely low, says Koichi Tanaka of Shimadzu Corporation. We found that the ratio of these proteins accurately indicates the amount of amyloid in the brain.”
When this method of diagnosis in medical practice while to speak early – it is necessary to conduct more research, but it can already be used for selection of participants in clinical trials.
Although not yet a reliable therapy of Alzheimer’s disease, the appearance of analysis is capable of diagnosing the disease years before the onset of symptoms, will give patients the opportunity to take countermeasures.
“In the future, in five years, people age 55 or 60 years, will be regularly tested for Alzheimer’s, every five years,” said Colin masters, a co-author published in the journal Nature article.
Previously, scientists claimed that daytime sleepiness may be associated with Alzheimer’s disease.
As reported, polluted air, according to researchers, can provoke the development of Alzheimer’s.
