Gut Bacteria May Predict Parkinson’s Before Symptoms Appear
Neuroscience News • • health
Key Points:
- Researchers at University College London (UCL) have identified a distinctive gut microbial signature that appears years before Parkinson’s disease symptoms, enabling early detection through a simple fecal sample.
- The study found that individuals with a high-risk genetic variant (GBA1) have gut microbiomes resembling an intermediate stage of Parkinson’s, suggesting the gut is an early site of disease development.
- Findings were validated across diverse populations in the UK, Korea, and Turkey with over 1,400 participants, demonstrating the microbial signature’s consistency across different cultures and diets.
- UCL is leading clinical trials exploring whether modifying gut bacteria, including using common cough medicines, can slow Parkinson’s progression, potentially opening new prevention and treatment avenues.
- The research highlights the potential for diet and microbiome analysis to identify at-risk individuals and reduce Parkinson’s risk through early intervention.
