That may soon change, however. One woman identified that she seemingly had the ability to “smell” the disease in those affected, and is now working with scientists to develop a test for the condition.

The human sense of smell, by and large, isn’t particularly impressive. It helps us enjoy the scent of fresh bread baking in an oven, or the aroma of freshly cut grass. However, as a tool for inspecting and learning about the world around us, it really comes up short.

The idea that someone could “smell” a difference with people with Parkinson’s disease is an easy one to test. When Milne eventually put the idea together that the different smell she noticed was perhaps related to her husbands condition, she quickly drew the interest of scientists. With the aid of her partner, a former doctor, she teamed up with researchers Dr. Tilo Kunath and Professor Perdita Barran to investigate further.
