65-year-old Joy Milne can reportedly sniff out people with Parkinson's disease. A few years earlier she noticed a musty odor in her husband and kept that in mind and six years later, he started being treated with drugs for the disease.
It can be noted that she correctly detected that there was something odd regarding the way her husband smelled and remembered it even after so many years.
This lady made a link between the disease and the scent given out by patients and that's how she started detecting that Parkinson patients give out a specific odor even before they are detected with the disease.
Researchers at the University of Manchester discovered that Mrs Milne could correctly identify the scent of future patients which would suffer from Parkinsonism.
