How To Diagnose Alzheimers With A Blood Test - Diagnosing Alzheimers

How To Diagnose Alzheimers With A Blood Test - You can predict the onset of Alzheimer's? According to a new study, released recently on Genome Biology, would be possible thanks to a simple blood test that could allow to identify the first signs of the disease and the advance of beta-amyloid plaques, the toxic protein that Smothers neurons and makes the disease progress. All this before this condition may damage the brain, causing memory loss, loss of memories and affections.

Research

More than 200 people have been tested by analyzing microRNAs snippets 140 (parts of the genetic code) in patients with Alzheimer's disease and in healthy people. The comparison, made by German researchers at the University of Saarland, has made it possible to highlight 12 microRNAs present in larger amounts in people with Alzheimer's disease. The test results were very accurate with a percentage of accuracy equal to 93%. Predict Alzheimer's to 20 anniPer now it is just experimental studies, and the marketing of these blood test is still premature.

However, a group of researchers from various institutes and universities, the Banner Alzheimer's Institute in Arizona, Boston University and the University of Antioquia, they identified the "markers", diagnostic signs present in the blood that indicate a possible pathology, which could reveal as early as 20 years if you become ill with Alzheimer's.

The Lancet Neurology research has made it possible to discover a "spy" genetics, mutation of the gene called presenilin (PSEN 1) 1, which anticipates the diagnosis of Alzheimer's disease, familial form what can be "inherited" by the genetic parents and that may occur after the 40 years with the first signs of cognitive impairment.

We hope that this technique, which could be extended to the most common Alzheimer's, can be used soon preventing the disease by administering drugs.
