Adaptive Deep Brain Stimulation (aDBS) is a new way to help people with Parkinson's Disease (PD). It uses a special device called the "AlphaDBS" System to send electrical signals to the brain. This study tests if aDBS is safe and works well.

There are two parts to the study: a short-term part and a long-term part. In the short-term, patients will try two different types of brain stimulation for two days in a hospital. Doctors will check to make sure it's safe and see how well it works. If the patients are doing okay, they can continue to the long-term part, where they will use the device at home for one month.

• The study involves 2 days in a hospital and 1 month at home.
• Patients must already have or need a new brain device.
• Doctors will check for any side effects or problems.

If you decide to join, know that doctors will be there to monitor your progress and help if you have questions. It's important to understand the study and agree to participate, and you should have someone, like a caregiver, to assist you.
