Brain Stimulation for Parkinson's Disease
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores how deep brain stimulation (DBS) can improve movement and speech in people with movement disorders like Parkinson's Disease. Researchers will test DBS effects during surgery by using special electrodes to observe changes in movement and brain activity. The goal is to understand DBS mechanisms and potentially improve treatment methods. The trial seeks participants with essential tremor or Parkinson's who are already scheduled for DBS surgery and have symptoms affecting one side more than the other.
As an unphased trial, this study offers a unique opportunity to contribute to groundbreaking research that could enhance future treatment options.
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 study team or your doctor.
What prior data suggests that this brain stimulation technique is safe for Parkinson's disease patients?
Research has shown that deep brain stimulation (DBS) is generally safe for people with Parkinson's disease. Studies have found that DBS can improve movement with fewer side effects than other treatments. For example, some individuals can reduce their medication doses after receiving DBS, indicating that the treatment is well-tolerated over time.
Similarly, direct cortical stimulation (DCS) is also considered safe. One review noted that while some individuals felt sensations under the electrodes, DCS remained a safe and manageable procedure.
Both treatments aim to address movement problems in Parkinson's disease, and current research supports their safety. However, discussing potential risks and benefits with a healthcare provider is important.12345Why are researchers excited about this trial?
Researchers are excited about these treatments for Parkinson's disease because they offer a new approach to managing symptoms. Unlike standard treatments like medication and traditional deep brain stimulation, direct cortical stimulation and deep brain stimulation of the motor thalamus target specific brain areas more precisely. This precision could potentially improve movement control and reduce side effects related to speech and swallowing. These new methods aim to provide more effective and personalized treatment options for individuals with Parkinson's disease.
What evidence suggests that this trial's treatments could be effective for Parkinson's Disease?
Past studies have demonstrated that deep brain stimulation (DBS) effectively helps people with Parkinson's disease by reducing symptoms like tremors, slow movement, and muscle stiffness. Research shows that individuals with DBS often require less medication, improving their quality of life. In this trial, participants will receive either DBS of the motor thalamus or direct cortical stimulation. Direct cortical stimulation, which involves stimulating the brain's outer layer, has shown mixed results. Some studies found it aids thinking and movement, while others observed no significant change. Overall, both treatments hold potential, but direct cortical stimulation is less consistently effective than DBS.25678

Are You a Good Fit for This Trial?
This trial is for patients who are already scheduled to have deep brain stimulation (DBS) surgery for movement disorders like Parkinson's disease, essential tremor, or the effects of stroke or traumatic brain injury. Participants should be able to undergo additional testing with a temporary electrode during their DBS procedure.Inclusion Criteria
