Summary

This study looks at how the nerves connecting the gut and brain affect Parkinson's disease. Researchers will compare people with Parkinson's, those at risk, and healthy volunteers. Participants will give blood, stool, and saliva samples, have X-rays and colon exams, and answer questionnaires over 2 years. The goal is to understand the gut's role in Parkinson's, not to test a treatment.
