Blood test for Alzheimer's shows 100 percent accuracy in early trials

Naturally, this makes it tricky to detect early on, which is problematic because treatment options only narrow as the disease progresses. But researchers may have now uncovered what could become a hugely valuable diagnostics tool, developing a blood test capable of picking up early stage Alzheimer's with "unparalleled accuracy."

"It is now generally believed that Alzheimer's-related changes begin in the brain at least a decade before the emergence of telltale symptoms," says Dr. Robert Nagele, from Rowan University School of Osteopathic Medicine. "To the best of our knowledge, this is the first blood test using autoantibody biomarkers that can accurately detect Alzheimer's at an early point in the course of the disease when treatments are more likely to be beneficial – that is, before too much brain devastation has occurred."

Studies have shown how the disease wreaks havoc in its formative stages, destroying brain cell connections that later leads to common symptoms like memory loss and confusion. Researchers are working toward methods that would enable earlier detection of the disease, with non-invasive MRIs and biosensors approaches that have shown real potential in recent times.
