My breath can reveal quite a bit about me... how much I've had to drink, for example. But it could also help with diagnosing Parkinson's disease.
Scientists have found they can identify people with Parkinson's by examining their breath. The test works by looking for small amounts of volatile organic compounds and the characteristic patterns these form when someone has the disease. Doctors currently diagnose Parkinson's by looking at symptoms and other test results, but the breath test could act as an additional quick and painless tool.
