Gastrointestinal Natural History Study

The Parkinson’s Institute and Clinical Center is performing a research study to understand more about the gastrointestinal symptoms that happen with Parkinson’s disease, and how these symptoms may change over time. Many patients with Parkinson’s disease (PD) have problems with gastrointestinal (gut/bowel) function, such as constipation. Although PD is typically diagnosed because of movement problems such as tremors, and slowness, scientists believe the disease also affects other body functions. Some of these effects on other body functions may start happening even before any movement problems are noticed.

The GI Natural History Study includes several groups: People with PD who have problems with their gastrointestinal function; People with PD who do not have problems with gastrointestinal function, and; People without PD who have certain combinations of REM sleep behavior disorder (RBD), and/or an abnormal smell test, and/or a relative with PD, and/or certain genetic mutations.
