Gut microbiome and tryptophan in Parkinson's disease
Part of Brain & nervous system clinical trials.
This study looks at the gut bacteria and a chemical called tryptophan (found in some foods) in people with Parkinson's disease compared with healthy people. It may help explain how the gut relates to Parkinson's symptoms. Participants will be asked to provide a stool sample.
Summary written for real people, not researchers, by Clin2.

- You must be between 45 and 90 years old
- You must be able to provide a stool sample
