A new blood test may be able to predict whether a person will go on to develop Parkinson's disease up to seven years before any symptoms arise.
The test looks at proteins in the blood whose concentrations differ in people with Parkinson's and those without. Using the test and an artificial intelligence (AI) tool, scientists could identify people with a confirmed Parkinson's diagnosis, as well as those within an at-risk group who would go on to develop the condition.
