Researchers have developed a PCR assay to detect higher levels of mitochondrial DNA damage in blood cells.
A new blood test could detect Parkinson’s disease earlier and help to determine who might benefit from specific treatments.
Parkinson’s is a progressive brain condition that causes shaking, involuntary movement, stiff muscles and slow movements.
It can also cause cognitive impairment and mental health disorders and gets worse over time.
More than 8.5 million individuals are estimated to be living with Parkinson’s disease globally, according to the World Health Organization (WHO).
