Parkinson's disease (PD) is a brain disorder causing movement problems and sleep issues. This study looks at how a treatment called **Subthalamic Nucleus Deep Brain Stimulation (STN-DBS)** affects sleep in people with PD. DBS is a therapy that sends electrical signals to the brain to help with movement symptoms. Researchers believe it might also help with sleep, but they need to learn more about how it works. The study will use a **Polysomnography (PSG)** device, a tool worn to record sleep patterns, and **Local Field Potentials (LFPs)**, which are brain signals, to understand changes in sleep patterns with DBS therapy.

• **Study Length:** Participation lasts over a year, with visits at 1, 3, 6, and 12 months.
• **Compensation:** Not mentioned in the details provided.
• **Risks:** Involves surgery and may not be suitable for those with severe illnesses or mental health issues.

To join, you must have PD, have had DBS surgery, and be willing to attend follow-ups. You cannot join if you've had other brain surgeries or have other serious health conditions.
