Scientists have developed a fast, non-invasive blood test that can detect Parkinson’s disease before tremors begin. By measuring RNA fragments that reflect brain pathology, the test offers new hope for early diagnosis and targeted intervention.

In a recent study published in the journal Nature Aging, researchers evaluated whether a blood test measuring nuclear and mitochondrial transfer RNA (tRNA) fragments could accurately detect pre-symptomatic Parkinson’s disease (PD).
Background
What if we could detect PD before a single tremor begins? PD is the second most common neurodegenerative disorder globally, affecting over 10 million…
