I posted this some time back. It's a strange story. I wondered at first whether they had trained dogs to smell it, as they do with cancer.


Thanks! I searched before posting, but for some reason it didn't come up.

It really makes me wonder how strong of a smell it is.

People are sensitive to different smells. Perhaps you and I couldn't pick it up at all. My husband has a terrific sense of smell, far better than mine; but I can smell mould a mile off and he can't smell it at all.

Their sebum is more copious and the fatty components are different, sebum smells quite strong to me so I’d imagine the sebum of Parkinson’s sufferers is noticeable if you are good at differentiating smells.
