New Alzheimer’s blood test may tell when symptoms are around the corner A novel biomarker beats the leading diagnostic blood test at predicting disease progression. Small loops of genetic material may be strong indicators of imminent Alzheimer’s disease (AD) symptoms. In a National Institutes of Health (NIH)-funded study, researchers showed that elevated levels of certain circular RNAs (circRNAs) in the blood nearly tripled patients’ risk of developing symptoms, suggesting these molecules are more sensitive to symptom onset than traditional AD biomarkers. https://www.nih.gov/news-events/news-releases/new-alzheimers-blood-test-may-tell-when-symptoms-are-around-corner
