Could a skin odor test result in early diagnosis of Parkinson’s disease?

Researchers from the University of Manchester (UK) have discovered small molecules in sebum secreted by the skin that are responsible for a unique scent in individuals with Parkinson’s. This discovery could lead to the development of a much needed, early diagnosis test for the neurodegenerative condition resulting in treatment programs being initiated at an earlier stage. There is currently no definitive diagnostic test available for the neurodegenerative disorder, however, it is already known that Parkinson’s can cause excessive production of sebum, a lipid-based fluid that moisturises and protects the skin.
