A Blood Test for Alzheimer’s Disease?

February 15th, 2017

Alzheimer’s disease is the most common form of dementia, affecting as many as 5 million Americans. Currently, there is no single test to identify the cause of the dementia symptoms, and many people suffering with dementia never get a definitive diagnosis. However, a breakthrough may be within reach.  In a recent issue of The Journal of Alzheimer’s Disease, University of Pittsburgh researchers Drs. Oscar Lopez and James Becker announced the development of a blood test that may be able to diagnose Alzheimer’s disease. The blood test looks for the presence of abnormal tau proteins in the blood, which are linked with Alzheimer’s disease.

Since current testing to diagnose Alzheimer’s disease involves an extensive battery of physical, mental, and imaging tests, this new blood test has the potential to save time, money, and effort. The test may also allow for an earlier diagnosis that will maximize the benefits of treatment and allow patients and their families more time to plan for the future.
