Scientists discover new early warning sign of Parkinson’s disease

  • Scientists at University College London (UCL) have discovered that people with Parkinson's disease possess a distinct set of gut microbes.
  • This unique gut microbe composition is also present in healthy individuals who carry the GBA1 gene variant, which significantly increases Parkinson's risk, even before they develop symptoms.
  • The findings, published in Nature Medicine, suggest that changes in gut bacteria could serve as an early warning sign for Parkinson's disease, potentially years before symptom onset.
  • Researchers believe this discovery could lead to the development of new diagnostic tests to identify individuals at risk and new preventative treatments targeting the gut microbiome.
  • The study also indicated that a balanced and varied diet might correlate with a lower likelihood of having gut microbiomes associated with an elevated risk of Parkinson's.
