Researchers find Parkinson’s could be diagnosed by distinctive odour

These findings could be used to develop early diagnostic tests for the neurodegenerative disorder, which leads to progressive brain cell death and significant loss of motor function. There are currently no definitive diagnostic tests available in the market.

The research was led by the University of Manchester and was funded by Parkinson’s UK and the Michael J. Fox Foundation.

The University of Manchester’s honorary lecturer Joy Milne noticed that people with Parkinson’s had a different smell and its intensity changed as the condition advanced. She first smelled this odour in her husband Les many years before he was clinically diagnosed with Parkinson’s.
