Simple Breath Test Could Help Detect Parkinson's Disease

There's currently no cure for Parkinson's disease, but researchers say they could be on their way to identifying it via a simple breath test.

Cambridge researchers say a small group of people tested - 57 - showed breath could differentiate those with Parkinson's from those without it.

The idea is certain molecules in a person's breath could help researchers detect early stages of the disease. Currently, researchers say, tests involve invasive procedures, normally only produce semi-accurate predictions and sometimes still don't detect Parkinson's until too late.

Parkinson's disease is a neurological condition that affects nerve cells. It can produce shaking or tremors of the body and can often hinder a person's ability to walk and talk.

The idea of sniffing out Parkinson's isn't too farfetched though.

Breath tests have already successfully worked in prior studies for detecting heart failure, liver and kidney diseases and cancer.

Clinical leader of the study, Professor Roger Barker, said, "We're hoping it will not only improve diagnosis, but also that it will tell us more about how Parkinson's develops and whether there are different types of Parkinson's."

According to the Parkinson's Disease Foundation, an estimated 60,000 Americans are diagnosed with the disease every year. About 10 million people are living with it worldwide.

Researchers say their next step is to test more people over a three-year span. The research was funded by the Parkinson's UK and the British Council.
