Researchers have developed a blood test that detects Parkinson's disease, potentially establishing a way to help diagnose the condition before nervous system damage worsens.
would be a major advancement for Parkinson's disease, which afflicts 10 million people worldwide and is the second-most common neurodegenerative disease after Alzheimer's. Led by a team of Duke Health neuroscientists, the study appeared Aug. 30 in the journal"Currently, Parkinson's disease is diagnosed largely based on clinical symptoms after significant neurological damage has already occurred," said senior author Laurie Sanders, Ph.D.
Earlier studies have associated mitochondrial DNA damage with an increased risk of Parkinson's disease, and the Duke-led team had previously reported an accumulation of mitochondrial DNA damage specifically in the
