ALISO VIEJO, Calif.--(BUSINESS WIRE)--A new blood test reliably predicts whether a person is likely to develop Alzheimer’s Disease (AD) up to 10 years before the disease is diagnosed, according to a multi-site study recently published in the Alzheimer’s Association journal Alzheimer’s & Dementia.
The study was conducted by Ed Goetzl, M.D. and others. Researchers used a unique approach to identify and isolate a well-known neural biomarker called p-tau, which previously had not been detectable in blood. Study results showed that the assay could correctly classify 96.4% of AD cases and could identify pre-symptomatic patients up to 10 years prior to diagnosis. Consisting of two phases, the study involved a total of 162 subjects, half of them Alzheimer’s disease patients and half of them controls.
