Parkinson's Disease (PD) affects how well the brain controls actions. In this study, we're looking at how deep brain stimulation (DBS) helps or doesn't help with stopping actions when needed. DBS is a surgery where small wires are put in the brain to send electrical signals to certain areas to help control movements. We'll check how this affects thinking and behavior in people with PD. We'll do this by studying people before, during, and after the DBS surgery. We will also compare how people with PD do with stopping actions compared to healthy people.
- Participation lasts up to 18 months for PD patients, but healthy volunteers only need 2 visits.
- The study is safe and will not change the usual PD treatments.
- Involves testing PD patients on medication and with different DBS settings.
To join, PD patients need to have a certain stage of illness and cannot have severe symptoms that mess up tests. Healthy people aged 45-75 can join if they don't have certain mental health issues or take specific medications.
