What this research studies

Many people with Parkinson's disease experience constipation before other symptoms appear, suggesting a link between gut health and the brain. This project aims to understand if changes in gut bacteria, called dysbiosis, cause or result from Parkinson's disease. We will look at gut bacteria and their byproducts in people with Parkinson's at different stages and with varying symptoms. By collecting clinical information and stool samples over time, we hope to uncover how gut bacteria influence the disease.

Who could benefit from this research

Good fit: This research is looking for people with Parkinson's disease who have different ages of onset, clinical symptoms, and disease severity.

Not a fit: Patients not diagnosed with Parkinson's disease would not directly benefit from this specific research.

Why it matters

Potential benefit: If successful, this work could lead to new ways to predict, prevent, or treat Parkinson's disease by targeting gut bacteria.

How similar studies have performed: The idea of a "Gut Microbiome-Brain Axis" in Parkinson's disease is a growing area of interest, with other research also exploring this connection.
