A new study from the University of Bristol found that dogs could detect it Parkinson’s disease Before symptoms appear.
Previous studies have shown that people with Parkinson’s disease have an increased amount of sebum on their skin, in oily, waxy substances with a distinctly scented smell.
The woman says the dog detected breast cancer before the doctor did: “He’s always known this.”
In a new study, Two dogs More than 200 odor samples trained with more than 200 odor samples were presented with 130 people with Parkinson’s disease and 175 people without illness, according to a press release.
The dog, a golden retriever named Bumper and a black Labrador named Peanut, was rewarded for actively identifying Parkinsonson samples and ignoring negative samples.
The dogs were up to 80% susceptible. In other words, 80% of people who suffered from illness identified the time.
They achieved a specificity of up to 98%.
The University of Bristol collaborated with the University of Manchester with Medical Detection Dogs on a study published in the Journal of Parkinson’s Disease on July 15th.
Experts say there is no early screening for Parkinson’s disease, but there are likely to be some early warning signs appear years or decades before the diagnosis.
“Identifying diagnostic biomarkers for PD, especially diagnostic biomarkers that may predict development or diagnose disease, is a lot of subject. Ongoing research“It has been released by Nicola Rooney, an associate professor at Bristol Veterinary School at the University of Bristol.”
“The dogs in this study achieved high sensitivity and specificity and showed that they are there. Olfactory signature It’s different from a sick patient,” she continued.
“Sensitivity levels of 70% and 80% are far outweighed opportunities. I think dogs will help develop fast, non-invasive and cost-effective methods to identify Parkinson’s patients.”

Claireguest, the UK’s Chief Science Officer of Medical Detection Dogs, reiterated that the study confirmed that dogs can detect diseases “very accurately.”
“Timely diagnosis Subsequent treatment is important as it may slow the progression of the disease and reduce the intensity of the symptoms,” she said in the release.
Perdita Barran, professor of mass spectrometry at the University of Manchester, said the study “adds to an increase in evidence that it is simple and non-invasive. Skin swab It can be used to diagnose Parkinson’s disease and provides a faster and more accessible method for early detection. ”

Future, the team will conduct long-term studies to assess Parkinsonson’s dog abilities prior to diagnosis.
The Michael J. Fox Foundation and Parkinson’s UK funded the investigation.
