**Study Overview:** *Parkinson's disease* is a condition that gets worse over time and affects how the brain controls movement. It happens when certain brain cells that make a chemical called *dopamine* stop working well. *Deep Brain Stimulation (DBS)* is a treatment where a device is placed in the brain to help control symptoms like shaking or stiffness when medications don't help enough. In this study, doctors are looking at two ways to replace the battery of the DBS device. One way uses *general anesthesia*, which puts you to sleep completely during surgery. The other way uses *regional anesthesia*, which makes only part of your body numb while you're still awake. The study will check which method helps with pain and how happy patients are with the results. **Key Points:** - Participants must be between 40-85 years old and have a certain health score called ASA I-II-III. - The study compares two anesthesia methods for battery replacement surgery. - It's important to consider the potential risks of anesthesia and how it may affect you.
