Area of Science:

  • Clinical Neuroscience
  • Neurology
  • Biomedical Engineering

Background:

  • Deep brain stimulation (DBS) is a gold-standard therapy for movement disorders when medical management fails.
  • The precise mechanisms underlying DBS therapeutic effects are not fully understood, hindering efficacy improvements and side effect reduction.
  • Understanding DBS network effects is crucial for advancing treatment strategies.

Purpose of the Study:

  • To review the emerging literature on the network effects of DBS.
  • To establish a framework for future research on DBS mechanisms and network modulation.
  • To explore how neuroimaging and electrophysiology can elucidate brain disorder pathophysiology and DBS response.

Main Methods:

  • Review of studies measuring DBS network effects using cerebral blood flow and metabolic imaging.
  • Analysis of functional imaging techniques to assess brain network alterations.
  • Inclusion of electrophysiological data (scalp and intracranial EEG, MEG) to evaluate network dynamics.

Main Results:

  • The review synthesizes findings from various neuroimaging and electrophysiological studies on DBS.
  • Identifies a growing body of evidence supporting the assessment of network effects in DBS research.
  • Highlights the potential of these methods to reveal underlying pathophysiology and treatment responses.

Conclusions:

  • Network-based approaches are essential for understanding DBS mechanisms.
  • Cerebral blood flow, metabolic imaging, and electrophysiology are key tools for studying DBS network effects.
  • This review provides a foundation for future research to optimize DBS therapies.
