Trial Summary

Do I need to stop my current medications for this trial?

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 data supports the effectiveness of the High-density Microelectrode for Parkinson's Disease treatment?

Research shows that using advanced microelectrodes for deep brain stimulation (DBS) can help manage Parkinson's disease by recording brain activity and adjusting stimulation based on individual needs. This approach has been validated in both human and animal studies, suggesting it can improve treatment outcomes by providing more precise and adaptive therapy.12345

What safety data exists for high-density microelectrodes used in deep brain stimulation for Parkinson's disease?

Deep brain stimulation (DBS) devices, which include high-density microelectrodes, have been associated with complications such as infections, lead migrations, and device malfunctions. Infections were the most common issue, affecting 16.2% of cases, and over a third of devices with adverse events required surgical intervention. Further research is needed to improve safety and reduce these complications.24678

How is the DBD Deep Array microelectrode treatment different from other Parkinson's disease treatments?

The DBD Deep Array microelectrode treatment is unique because it uses a high-density microelectrode array to both stimulate and record from multiple brain regions simultaneously, providing detailed insights into brain activity and neurotransmitter release, unlike traditional treatments that typically focus on either stimulation or recording separately.2591011

What is the purpose of this trial?

The purpose of this study is to test the ability of a newly-designed electrode to measure the activity of individual nerve cells (neurons), and collections of nerve cells (local field potentials) in the brain. The study's main goals are to see how well this electrode works compared to standard electrodes and to validate its safety.

Findings from Research

A review of 221 unique adverse events related to deep brain stimulation (DBS) devices for Parkinson's disease revealed that the most common complications were infections (16.2%) and lead migrations (8.6%).
Over 40% of the reported adverse events required patients to return to the operating room for device explantation or revision, highlighting the need for further research to improve the safety and reliability of DBS systems.
