How the brain controls stopping movements in Parkinson's disease

This study is exploring how the brain controls your ability to stop or inhibit movements — something that often becomes difficult for people with Parkinson's disease. Researchers will record your brain's electrical activity while you perform simple tasks that test your ability to stop or change movements. This basic science research aims to better understand why people with Parkinson's struggle with impulse control and stopping movements, which could eventually lead to better treatments.

People with Parkinson's disease often develop problems with stopping habitual movements (like uncontrolled gait acceleration) and controlling impulses (like overeating or gambling). Researchers want to understand what's happening in the brain to cause these problems, especially in patients who receive deep brain stimulation surgery, so they can develop better ways to help.
