This study looks at a possible new treatment for early-stage Parkinson's disease (PD). Parkinson's is a brain disorder that affects movement. The study uses a method called **taVNS**, which stands for _transcutaneous auricular vagus nerve stimulation_. This involves stimulating a nerve in your ear to help protect brain cells and potentially slow PD progression. The trial is _double-blind_, meaning neither the doctors nor the patients know who is receiving the actual treatment or a placebo, which helps ensure the results are fair.

To join, you need to be between 55-75 years old, diagnosed with Parkinson's less than 3 years ago, and currently taking standard PD medications. You can't join if you've used certain medications recently, have mental impairments, or other health issues like past strokes.

• The study tests a new method to help slow Parkinson's disease.
• Participation is for people diagnosed with Parkinson's in the last 3 years.
• Some health conditions or treatments exclude participation.
