In 2015, a woman named Joy Milne claimed she could smell Parkinson's disease. She first noticed the smell after her husband’s musk changed.
After her husband was diagnosed with the disease, the pair attended a support group for individuals with Parkinson’s.
During the first support meeting she attended, she noticed everyone had the same musk as her husband.
She became convinced that the smell was linked to the disease so she reached out to a university professor.
To test Joy’s ability, Professor Perdita Barran from the university of Manchester gave her 12 T-shirts to smell.
6 of the shirts were worn by individuals with Parkinson’s and the other 6 were worn by healthy individuals.
Joy correctly identified the 6 shirts, but also chose one from the control group. 8 months later, that person was diagnosed with Parkinson's.
