Deep Brain Stimulation (DBS) is a surgery for people with movement problems like Parkinson's disease, which do not improve with regular treatments. A small device called a neurostimulator, similar to a pacemaker, is put under the skin in the chest. This device sends signals to the brain to help block abnormal movements.

Adults 18 years and older with movement disorders such as Parkinson's disease, essential tremor, or dystonia can participate. Before surgery, doctors will check your health with physical exams, blood tests, and imaging. You'll practice movement and memory tests, which you will also do during surgery. After surgery, you’ll stay in the hospital to recover. The stimulator needs adjusting over time, so you'll have follow-up visits at 1, 2, and 3 months after surgery.

• Study involves several hospital visits and check-ups over a few months.
• The surgery aims to improve movement problems not helped by medication.
• Researchers will monitor brain activity during the procedure.
