First seen Jul 01, 2026 · Last updated Jul 01, 2026
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.

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.
