The Woman Who Can Smell Parkinson’s Shares How She Identified The Disease In Her Husband
Joy Milne possesses a remarkable ability to detect Parkinson’s disease by scent.
Although the ability to detect changes in body odor may seem like an unusual gift, it has led to groundbreaking discoveries in medical science. Our sense of smell, often overlooked in everyday life, holds the potential to reveal critical insights into our health.
This story delves into how one woman’s extraordinary sensitivity paved the way for advancements in the early detection of Parkinson’s disease.
For decades, Joy Milne, a Scottish woman, shared her life with her husband, Les. Growing up together since their teenage years, she became intimately familiar with his natural scent - a unique signature built over years of close companionship.
However, as time passed, she began to notice a subtle yet distinct shift in his odor. Unlike the typical changes associated with aging, this new scent hinted at something more profound.
The human body naturally undergoes changes as it ages, including the production of a compound called 2-nonenal, which alters body odor over time. Yet, Joy’s observations suggested that this alteration could not be solely attributed to aging. The change was distinct, carrying undertones that pointed toward an underlying health issue.
Joy’s heightened sense of smell was not a random quirk but an extraordinary ability akin to that seen in trained animals. Dogs, for instance, are known to detect diseases like cancer or predict seizures through scent. Similarly, Joy’s olfactory sensitivity enabled her to identify markers associated with Parkinson’s disease - a discovery that would later prove transformative.

Before her husband’s 32nd birthday, Joy began noticing a musky and damp odor emanating from him. At first, she attributed this unfamiliar scent to environmental factors or minor lifestyle changes. However, as years went by and Les was diagnosed with Parkinson’s disease in his mid-40s, Joy connected his altered scent to the onset of the condition.
"Les and I should have been enjoying retirement, but Parkinson’s had stolen our lives," she said.This realization marked the beginning of a journey that would bridge personal experience and scientific exploration.

The connection between Les’s diagnosis and his changing scent sparked Joy’s curiosity. Attending a Parkinson’s support group further validated her observations; she detected the same distinct odor among other individuals with the disease. This repeated experience confirmed that her sense of smell was not merely subjective but could serve as a reliable marker for Parkinson’s.
Her unique ability caught the attention of researchers at the University of Manchester. Collaborating with scientists, Joy participated in experiments designed to test whether her olfactory skill could aid in diagnosing Parkinson’s disease. Using items such as T-shirts or swabs soaked in sebum, the oily substance produced by the skin, Joy identified specific odors linked to the condition with remarkable accuracy.
Joy’s husband, Les, passed away in 2015 at the age of 65.
The research conducted alongside Joy revealed significant findings. Sebum samples from individuals with Parkinson’s disease contained elevated concentrations of compounds such as hippuric acid, eicosane, and octa decanal. These substances were identified using mass spectrometry and found at much higher levels compared to those without the disease.
Joy’s olfactory assessments achieved an impressive 95% accuracy rate in identifying individuals with Parkinson’s based on their scent alone. These results demonstrated that the chemical markers associated with Parkinson’s were consistent and detectable through smell.
Her contributions were recognized in academic publications like ACS Central Science, and she was even named an honorary lecturer at the University of Manchester.

"The woman who can smell Parkinson's disease"
The discovery of volatile biomarkers tied to Parkinson’s disease has far-reaching implications for medicine. Currently, there is no definitive diagnostic test for Parkinson’s; clinicians rely on observing motor symptoms like tremors and rigidity, which typically appear only after significant neurological damage has occurred. Early detection is crucial because it offers a window for intervention that could slow disease progression and improve patients’ quality of life.
The research inspired by Joy Milne suggests that non-invasive diagnostic tools could be developed based on scent detection. For instance, a simple swab test analyzing sebum could potentially diagnose Parkinson’s within minutes—a significant improvement over current methods.

This extraordinary ability to detect Parkinson's disease through smell represents more than just a scientific curiosity – it opens new chapters in medical diagnostics.
This story, connecting personal experience and scientific research, points to the revolutionary potential of an interdisciplinary approach to health challenges. Experts emphasize that non-invasive detection methods, inspired by Milne's ability, could significantly advance the early diagnosis of this severe neurological disease.
"Such discoveries fundamentally change our perspective on diagnostic possibilities," note scientists involved in the project.
According to the latest research results, practical tools for early detection of Parkinson's disease are expected to be developed in the coming years, which could bring a crucial advantage in treating millions of patients worldwide.
