Could zapping the ear unlock Gut-Brain secrets in Parkinson's?

NCT ID NCT07673146

First seen Jun 29, 2026 · Last updated Jun 30, 2026 · Updated 1 time

Summary

This study investigates how stimulating the vagus nerve through the ear affects stomach function and brain activity in people with Parkinson's disease. Participants receive non-invasive electrical stimulation via a device placed on the ear, and researchers measure stomach responses with MRI and brain activity with fMRI. The goal is to better understand gut-brain communication in Parkinson's, which may lead to new insights into the disease.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

UROstim (non-invasive ear stimulation device)

What this could lead to

If successful, this could reveal how gut-brain signals influence Parkinson's symptoms, potentially pointing toward new non-drug therapies.

What could go wrong

This is an early exploratory study with only 45 participants, so results may not apply broadly. The stimulation is temporary and not intended as a treatment.
