Scientists call the new experimental blood test is an incredibly accurate way to detect Alzheimer’s disease. Experts are sure they have made a breakthrough which will make diagnosis easier and more widely available.
According to the New York Times, the test allows us to determine suffer if the person with dementia from Alzheimer’s disease, and not from any other cognitive diseases. It is also able to identify the signs of the disease for 20 years before patients would be expected to have problems with memory and thinking.
“Blood test accurately defines, who in the future will find Alzheimer’s disease. — The Times said Dr. Michael Weiner of the University of California in San Francisco- This applies even to those who have no symptoms.”
The study was published in JAMA Network Open and presented at the Alzheimer’s Association International Conference.
According to scientists, the blood test is as accurate as more invasive techniques like MRI scan of the brain, but more simple and available way of finding out whether patients suffer from cognitive disorders from Alzheimer’s.
Moreover, experts believe, over time it will help to predict the development of the disease in perfectly healthy patients.
“It’s not a cure, but it is not possible to treat the disease, not being able to diagnose. Accurate, inexpensive diagnostics <…> is for us a real breakthrough,” said Weiner, who was not involved in the study.
Scientists believe that the test is ready for clinical application within the next 2-3 years.
Nearly 6 million people in the United States and about 30 million worldwide have Alzheimer’s disease. Presumably, by 2050 this number will more than double.
