About this study

In plain language

This study looks at how deep brain stimulation (DBS) for Parkinson’s disease affects attention and how people judge where things are around them. It also looks at how trouble paying attention to what people see is linked to freezing of gait, when walking suddenly stops. It is for adults with Parkinson’s disease who have freezing of gait and have had DBS surgery on both sides of the brain.

The purpose of this research is to determine how deep brain stimulation (DBS) for Parkinson's disease affects attention and visuospatial function. Additionally, this study will evaluate how deficits in visual attention are associated with freezing of gait (FOG) in Parkinson's disease. There is currently no reliable treatment for FOG and little is understood about the underlying reason this occurs. Some recent research has found that stimulating the right side of the brain seems to improve FOG. The right side of the brain is also paramount for visual attention, which is why investigators are conducting this study.

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Eligibility

Who can join

  • You are older than 18.
  • You have freezing of gait, when walking suddenly stops.
  • You have had DBS surgery on both sides of the brain in an area called the subthalamic nucleus (STN) as part of your Parkinson’s care.

Who can't join

  • You report vision or hearing problems that have not been corrected.
  • You are pregnant or expect to become pregnant during the study.
  • You have dementia, which affects memory and thinking, or areas of brain damage that affect thinking or walking.
