Parkinson's Disease (PD) affects the brain, but it may also be linked to changes in the gut. This study looks at a gene called csgA, found in gut bacteria, to see if it plays a role in PD. csgA helps certain bacteria make structures similar to those in human brains involved in PD. By understanding csgA better, scientists hope to develop new treatments for PD.

• **Duration:** This study is ongoing; participants should expect regular check-ins.
• **Visits:** Participants need to visit the study site for assessments and provide consent.
• **Eligibility:** Participants must be 18-80 years old, have had PD for less than 10 years, and have or had gut issues.

If you are interested, ensure you meet the requirements, like not having significant GI disorders or recent infections. Your involvement could help develop new ways to treat Parkinson's by targeting gut bacteria! Please talk with your doctor to understand any risks or benefits before participating.
