Adaptive DBS Algorithm for Personalized Therapy in Parkinson's Disease (ADAPT-PD) China Study

This study is testing a smarter, adaptive version of deep brain stimulation (DBS) for people with Parkinson's disease. Standard DBS delivers a constant electrical signal to the brain, but this study tests a system that automatically adjusts based on real-time brain signals, potentially providing better symptom control. **You may be eligible if...** - You have been diagnosed with Parkinson's disease - You already have a Medtronic Percept PC or Percept RC DBS device implanted (for at least 3 months) - Your DBS settings and medications have been stable for at least 4 weeks - Your doctor believes your DBS therapy is helping you - You are able to attend all study visits and complete required questionnaires **You may NOT be eligible if...** - You do not already have the compatible Medtronic DBS device - Your DBS or medications have been changed recently - You are pregnant or planning to become pregnant - You are unable to comply with study procedures Talk to your doctor to see if this trial is right for you.
