Area of Science:

  • Neurosurgery
  • Neuroethics
  • Medical Ethics

Background:

  • Deep brain stimulation (DBS) is an established neurosurgical treatment for Parkinson's disease (PD) and essential tremor (ET).
  • DBS shows potential for psychiatric conditions like treatment-resistant depression and OCD.
  • Despite its efficacy, DBS is invasive, costly, and raises significant ethical and social concerns, particularly with emerging psychiatric applications.

Purpose of the Study:

  • To identify and characterize current and emerging ethical and social issues associated with Deep Brain Stimulation (DBS).
  • To analyze the implications of DBS use in both established neurological and developing psychiatric applications.

Main Methods:

  • Comprehensive review of neurosurgical, medical ethics, psychological, and sociological literature.
  • Consultation of USPTO database, FDA regulations, and manufacturer business reports.

Main Results:

  • Significant ethical and social challenges exist in DBS practice, including patient selection, informed consent, resource allocation, and public perception.
  • These challenges are anticipated to intensify with the expansion of DBS into psychiatric treatment.

Conclusions:

  • Several substantial ethical and social challenges in DBS require focused attention.
  • Neuroethics strategies, including expert consensus and public engagement, may effectively address these issues.
