Advancements in Blood Testing for Parkinson's Disease

Researchers have developed a blood test called Mito DNADX that can detect damage to mitochondrial DNA (mtDNA), which is associated with Parkinson's disease. The test was able to distinguish between individuals with Parkinson's disease and those without the condition, regardless of genetic risk factors or medication use. The test may not only aid in diagnosing Parkinson's disease but also identify potential treatments that can reverse or halt mitochondrial DNA damage. Further research is needed to validate the test in larger populations and track mtDNA damage as the disease progresses.
