A woman detects Parkinson’s disease through her sense of smell and prompts scientists for a screening test

You could say that she felt that there was something wrong with her husband. Scottish nurse Joy Milne, 72, has enabled scientists to take a major step forward in research into Parkinson’s disease. This woman is suffering from a disease called hyperosmia, which increases her ability to smell. Based on this genetic abnormality, Manchester researchers First created a test to detect Parkinson’s disease in patients.

Many years ago, Joy Milne found her husband, Les, an unusual smellwhich he did not have before. “A musty smell, not very pleasant, she narrates to the bbc, especially around his shoulders and around his neck; And the appearance of his skin was changed.” The smell persisted for twelve years without joy or lace, without knowing why the woman smelled it and what it meant. Then, Les is diagnosed with Parkinson’s. Joy then meets the other patients. Everyone, to him, smells like lace. So she understands and informs the doctors.

So researchers in Manchester relied on what Joy Milne describes to develop their screening test, the first of its kind. with a swab, Laboratory technicians come to collect sebum samples – the greasy substance on the surface of the skin that definitely spits out the smell of Joy Milne – back to the patients. They then analyze this sample in a mass spectrometer. Markers specific to Parkinson’s patients then emerge, or not. ,
