There is good news for the early diagnosis of Parkinson's. Because early diagnosis of Parkinson's is difficult, scientists in the UK have now found that people with Parkinson's disease who do not yet have symptoms may have a smell that smells unusually musky. The reason for this phenomenon is a group of ten characteristic fragrance molecules in the skin of Parkinson's patients. University of Manchester and Edinburgh researchers have been alerted to this unusual phenomenon by a Perth nurse. Joy Milne, the nurse's name, is able to identify individuals with the smell of Parkinson's disease among a variety of individuals. She was given 12 t-shirts, 6 Parkinson's and 6 non-ill people in one experiment. She recognized Parkinson's patients by their peculiar musky odor. From the non-diseased control group, however, she identified a person who actually manifested the disease months later, without anyone knowing at that time. Joy Milne's husband also contracted Parkinson's disease, and she also smelled the disease long before neurological signs were present. He died at the age of 65. The British scientists are hopeful in view of this fact to be able to develop a first screening test.
