Study Focus: This study investigates how deep brain stimulation (DBS), a treatment for Parkinson's disease, affects attention and visuospatial function (the ability to understand visual information about where things are in space). The study also examines how these changes relate to freezing of gait (FOG), a symptom where people with Parkinson's feel stuck and unable to move their feet when walking.

Key Points:

• The study involves people with Parkinson's who have had DBS surgery.
• Participants must be over 18 and experience FOG.
• Some people may not be eligible, such as those with certain visual or hearing impairments, pregnancy, or dementia.

The research aims to learn more about how DBS on the right side of the brain might help with FOG and improve attention, especially in spaces where you need to focus on where things are, like walking through a doorway. This study will help understand FOG better and find ways to treat it.
