Deep Brain Stimulation (DBS) is a treatment for Parkinson's Disease (PD), where a device is placed in the brain to help control symptoms like stiffness and shaking. However, some people with DBS might still have issues with balance and fall more often. This study wants to see how DBS affects thinking and movement, and if this is linked to a higher chance of falling.

Eligibility includes those aged 30-80 who have chosen DBS surgery and can walk. Participants must be available for follow-up. But, if insurance doesn't cover surgery costs, or if there are medical issues like high blood pressure or heart problems, you might not be eligible.

• The study will monitor changes in thinking and movement after DBS surgery.
• Participants should be available for follow-up visits to track progress.
• Key risks include potential falls and surgery costs might not be covered by insurance.
