Parkinson’s blood test could help develop cure, researchers say

The team developed an assay which showed higher levels of mitochondrial DNA damage in blood cells collected from patients with Parkinson’s disease compared to people without the condition.

Researchers hope their blood test could lead to a more ‘clear-cut’ diagnosis of Parkinson’s and better treatment for the disease (PA)

A blood test that can detect Parkinson’s disease could be a step towards finding a cure for the condition, researchers have suggested.

It is hoped the findings of a US study, published in the journal Science Translational Medicine, could lead to treatments that halt the progression of the disease before it affects a patient’s nervous system, or even help reverse damage on a cellular level.
