The woman who can smell Parkinson's disease

Joy Milne, a woman from Scotland, has a unique ability to smell Parkinson's disease. She first noticed this scent on her husband years before his diagnosis. Her ability was later validated through scientific experiments, where she identified the disease by smell before clinical diagnosis. Joy's mission is to help scientists develop early detection methods for Parkinson's, potentially reducing the damage caused by late diagnosis.
