Johns Hopkins Reports Breakthrough in Alzheimer's Early Detection Using Blood Biomarkers
β’ Researchers at Johns Hopkins University published findings in Nature Medicine on March 20 showing a blood test can detect Alzheimer's pathology 15-20 years before symptom onset with 94% accuracy. β’ The test measures phosphorylated tau and amyloid-beta levels and was validated in 2,100 cognitively normal participants followed for up to 12 years in multiple longitudinal cohorts. β’ Early detection could enable preventive interventions during the asymptomatic stage, potentially delaying or preventing cognitive decline in the 6 million Americans living with Alzheimer's disease.
