Deep Brain Stimulation Targets, Technology, and Trials: Two Decades of Progress

Area of Science:

• Neuroscience
• Neurosurgery
• Biomedical Engineering

Background:

• Alzheimer disease (AD) presents a growing global health challenge with limited treatment options.
• Deep brain stimulation (DBS) is an emerging therapeutic strategy for neurodegenerative conditions.
• Microelectrode recording (MER) offers potential for precise targeting in neurosurgical interventions.

Discussion:

• The integration of MER with DBS for AD aims to enhance surgical accuracy and therapeutic efficacy.
• Challenges include the complex pathophysiology of AD and the need for robust neurophysiological markers.
• Ethical considerations and patient selection are crucial for the successful application of DBS in AD.

Key Insights:

• MER successfully guided electrode placement in a cohort of AD patients undergoing DBS.
• Distinct neurophysiological patterns were identified during MER, potentially correlating with disease progression.
• Preliminary data suggest MER can refine DBS targeting for AD, warranting further investigation.

Outlook:

• Future research should focus on larger clinical trials to validate MER-guided DBS for AD.
• Long-term studies are needed to assess the sustained efficacy and safety of this approach.
• Advancements in MER technology could further improve its utility in AD treatment strategies.
