'Super-smeller' helps develop swab test for Parkinson's disease

Distinctive musky odour of people with Parkinson's could lead to earlier diagnosis

Scientists have developed a test for Parkinson's disease based on its signature odour after teaming up with a woman who can smell the condition before tremors and other clinical symptoms appear.

The test could help doctors diagnose patients sooner and identify those in the earliest stages of the disease, who could benefit from experimental drugs that aim to protect brain cells from being killed off.
