This study investigates how deep brain stimulation (DBS) surgery affects movement disorders such as Parkinson's disease, dystonia, and essential tremor. These disorders can cause abnormal movements, and DBS is a procedure that uses a device to send signals to the brain to help control these movements. The purpose is to understand how DBS impacts these conditions and to collect data on brain function during the surgery.
Participants will undergo various tests, including physical and neurological exams, to determine eligibility for DBS surgery. During the surgery, a device is placed in the chest to send signals to the brain. Participants will perform movement and memory tests before and during the surgery. After the procedure, they will have follow-up visits to adjust the device settings and monitor their progress.
- Who can participate: Adults aged 18 and older with movement disorders such as Parkinson's disease, dystonia, or essential tremor may be eligible. Participants must have conditions not adequately controlled by medication and be able to provide informed consent.
- Study details: Participants will undergo DBS surgery, where a device is implanted to control movement disorders. A placebo is not used in this study.
- Study timelines and visits: The study will last 3 months. The study requires 3 visits.
