AI blood test could detect Parkinson's disease up to 7 years before symptoms: 'Particularly promising'

Fox News' Dr. Marc Siegel has the latest on the treatment of the brain disease on'America Reports.' A new blood test could reveal Parkinson's diagnoses up to seven years before symptoms emerge. Researchers from University College London and University Medical Center Goettingen in Germany used artificial intelligence to develop the test. The study, which was published in the journal Nature Communications, included 72 patients with rapid eye movement behavior disorder (iRBD), a condition that has been linked to a higher risk of Alzheimer's. When the researchers used machine learning to analyze blood samples from the patients, they discovered that 79% of them had the same biomarkers as people with Parkinson's.
