A team of researchers from Rowan-Virtua School of Osteopathic Medicine (RowanVirtua SOM) and Durin Technologies, Inc., have announced the results of a newly-designed blood test that can detect the presence of Alzheimer’s disease-related pathology up to 10 years before symptoms arise with a nearly 97 percent accuracy rate. Their findings appear online ahead of press in the Journal of Alzheimer’s Disease.
The study involved 328 blood samples with the goal of determining if a test that monitors a small number of a patient’s autoantibodies can detect Alzheimer’s disease (AD)-related pathology at presymptomatic, prodromal (i.e., mild cognitive impairment), and mild-moderate stages of the disease.
The research team showed that their test, using just eight autoantibody biomarkers, could accurately identify the presence of Alzheimer’s disease pathology across the disease’s progression, including among those originally determined to have no trace of the disease.
For a number of reasons, the test has significant potential to impact effective treatments for Alzheimer’s disease. The test is minimally invasive and inexpensive, it can diagnose or predict clinical decline in asymptomatic individuals, and it can monitor a patient’s progress while under treatment, making it ideal for use in clinical trials and in frontline and community primary care settings, including those in rural and economically disadvantaged regions.
The researchers noted that the use of autoantibodies as blood-based biomarkers is particularly exciting because it enables development of a platform technology for early detection of multiple diseases.
