Deep Brain Stimulation for Parkinson's Disease
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to assess how deep brain stimulation (DBS) affects attention and visual thinking in people with Parkinson's disease, particularly those experiencing freezing of gait (FOG), a sudden inability to move. The study will test DBS by alternating its activation on different sides of the brain to determine its effect on FOG and attention. Participants must have Parkinson's, experience freezing of gait, and have undergone DBS surgery on both sides of the brain. As an unphased trial, this study provides a unique opportunity to enhance understanding of DBS's impact on cognitive functions in Parkinson's patients.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that deep brain stimulation is safe for Parkinson's disease?
Research has shown that deep brain stimulation (DBS) is generally safe for people with Parkinson's disease and is well-tolerated over time. One study followed patients for five years and found that DBS not only helped with movement problems but also remained safe. Another study found that a frameless system for DBS was safe and well-tolerated by patients. Overall, DBS has been effectively used in certain Parkinson's patients, and evidence suggests it is a safe option for managing symptoms.12345
Why are researchers excited about this trial?
Unlike the standard treatments for Parkinson's disease, which often involve medications like Levodopa that aim to replace dopamine, Deep Brain Stimulation (DBS) offers a different approach. Researchers are excited about DBS because it directly targets the brain's subthalamic nucleus (STN) with electrical impulses. This technique can help regulate brain activity more precisely and may lead to improvements in motor symptoms that medications alone can't achieve. Additionally, the trial explores the effects of turning DBS on and off on different sides of the brain, which could refine how we use this technology for better outcomes.
What evidence suggests that deep brain stimulation is effective for Parkinson's disease?
Research has shown that deep brain stimulation (DBS) in a specific brain area effectively treats Parkinson's disease. One study found that after five years, DBS greatly improved patients' movement and ability to perform daily tasks. Another study showed that DBS reduced discomfort and sensory issues related to Parkinson's after six months. Overall, DBS is a proven and safe way to help manage Parkinson's symptoms. In this trial, participants will receive STN-DBS with different configurations: one group will have the right STN-DBS on and left STN-DBS off first, while the other group will have the left STN-DBS on and right STN-DBS off first. Recent research suggests that stimulating the right side of the brain might help with freezing of gait (FOG), a common and difficult symptom of Parkinson's.23678

Are You a Good Fit for This Trial?
This trial is for individuals with Parkinson's Disease who experience gait impairment and visuospatial perception issues. It specifically targets those interested in how deep brain stimulation (DBS) might affect their condition, particularly freezing of gait.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants undergo lateralized STN-DBS stimulation to assess its impact on visuospatial attention and freezing of gait
Assessment
Participants are evaluated using tasks such as timed up and go, Go-No-Go, and Flanker tasks to measure changes in attention and freezing of gait
Follow-up
Participants are monitored for safety and effectiveness after treatment
What Are the Treatments Tested in This Trial?
Interventions
- STN-DBS
Trial Overview
The study tests the effects of activating right or left subthalamic nucleus (STN) DBS on attention and visuospatial function in Parkinson's patients. Researchers are exploring if stimulating one side can improve freezing of gait by alternating which side of the STN-DBS is turned on first.
How Is the Trial Designed?

Treatment groups
Active Control
STN-DBS will be turned off sequentially for each side, in this group beginning with right STN-DBS on and left STN-DBS off. This will then be followed by the corollary.
