This study began with ‘super smeller’ Joy Milne, who noticed her husband had a new ‘musky’ smell and was then diagnosed years later with Parkinson’s disease. It turns out Joy can detect the unique smell of Parkinson’s in patients, before they start displaying any symptoms. Researchers have used her amazing skills to help identify which exact chemicals are responsible for this scent, with a view to creating non invasive tests they can use on patients to detect Parkinson’s disease in patients much earlier.
