Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults over 18 with Parkinson's disease who experience freezing of gait and have undergone bilateral STN-DBS surgery.
✕Probably not a fit
Patients with uncorrected visual or hearing impairments, dementia, or significant brain lesions may not benefit from this study.

What this trial studies
This research investigates the effects of deep brain stimulation (DBS) on visuospatial attention and its correlation with freezing of gait (FOG) in individuals with Parkinson's disease. The study will evaluate how stimulation of the subthalamic nucleus (STN) influences visual attention and whether these changes are linked to improvements in FOG. Participants will undergo DBS with alternating stimulation of the left and right STN to assess the impact on their gait and attention. The findings aim to enhance understanding of FOG and potentially lead to new treatment strategies.
Why it matters
Potential benefit: If successful, this study could provide insights into effective treatments for freezing of gait in Parkinson's disease, improving patients' mobility and quality of life.
How similar studies have gone: While some studies have explored the effects of STN-DBS on gait and attention, this specific approach focusing on the correlation with freezing of gait is relatively novel.
