This study looks at how Deep Brain Stimulation (DBS) affects people with Parkinson's Disease. Parkinson's Disease is a condition that affects movement, making it hard to control your body. DBS is a surgery where doctors use tiny wires to send signals to the brain, which helps with movement problems. This study uses a frameless technique, meaning the surgery is done without a big frame around the head. Researchers will check how much patients' lives improve by using a special test called the PDQ-39 scale, which measures how Parkinson's affects daily life. They'll compare scores before surgery and one year later.

• The study is interested in both short-term and long-term effects.
• Participants need a confirmed diagnosis of Parkinson's and must be eligible for DBS.
• Patients who cannot give consent are not allowed to join.

The goal is to see if this type of surgery makes life better for patients with Parkinson's Disease.
