NCT04032262

Brief Summary

This study focuses on the relationship between the brain and the gut, and additionally will foster collaboration between Movement Disorder experts and Neurogastroenterologists to provide critical information and lead to innovative therapies in the future to treat GI dysfunction of Parkinson's Disease.

Study Arms (1)

Parkinson's Disease Relationship to the GI track

OTHER

Patients with Parkinson's.

Diagnostic Test: Gastrointestinal and Parkinson's Disease

Interventions

Subjects with Parkinson's disease will come for visits that will contain questionnaires about their PD, their bowel movements, and do further tests using anal rectal probes to understand further their constipation, and other tests to gather data on their digestion.
