NCT ID NCT07679529
First seen Jul 01, 2026 · Last updated Jul 02, 2026 · Updated 1 time
Summary
This study tests whether a small device that gently stimulates a nerve in the ear can help reduce depression in people with Parkinson's disease. Participants use the device at home twice a day for 14 days. The trial measures changes in mood and brain activity to see if this simple, non-invasive approach works.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- transcutaneous auricular vagus nerve stimulation (taVNS) device
- What this could lead to
- If it works, this could offer a non-drug, at-home option to help lift depression in people with Parkinson's disease.
- What could go wrong
- This is a small, early-stage study with only 30 participants, so results may not apply to everyone. The device may cause discomfort or not improve symptoms.
