A study published in the journal Neurology on Thursday reveals a new blood test that can detect Alzheimer’s up to 20 years before it begins wreaking its debilitating effects with 94 percent accuracy, according to The Guardian.
Scientists at the Washington University School of Medicine in St. Louis declared that the blood test can detect key changes in the brain that indicate the disease and believe that the new test represents a major step forward in the mission to find a cure for the neurodegenerative illness, which is characterized by memory loss and confusion.
Randall Bateman, professor of neurology and senior author of the study, commented on the results, stating that the blood test is much more effective and simpler than a PET brain scan, which is the typical way people are screened for the disease.
