"Revolutionary Method for Early Brain Disease Detection Unveiled"

The Michael J. Fox Foundation has made a groundbreaking discovery of a biomarker for Parkinson’s disease, allowing for the early detection of the disease before symptoms appear. The alpha-synuclein seeding amplification assay (SAA) can detect misfolded alpha-synuclein in spinal fluid with 90% specificity, providing a way to identify individuals with PD pathology before diagnosis. The breakthrough was achieved by using a scratch-and-sniff test to identify individuals with poor smell, a known predictor of brain disease. This development will revolutionize Parkinson’s research and care, potentially leading to widespread adoption of annual smell tests for early disease detection.
