A 'super smeller' who sniffed out her husband's Parkinson's a decade before it was diagnosed has revealed the tell-tale scents associated with other diseases.
Former nurse Joy Milne, of Glasgow, told her husband Les was smelling differently when he was still in his 30s, describing the scent as a 'woody, musky odor'. He was diagnosed with Parkinson's 12 years later, in 1985.
Joy's nose is so sensitive it's ready to pick up the smell of sebum – oil secreted by the skin – that's by Parkinson's patients.
Speaking on this morning, Joy, now in her late 60s, Parkinson's is not the only disease with a distinct scent.
She has been diagnosed with tuberculosis, while cancer has an 'earthy' scent. Alzheimer's smells 'sweet', but liver disease produces a 'strong smell of bile'.
