Deep brain stimulation for obsessive compulsive disorder: the functional neurosurgeon armamentarium

Deep brain stimulation (DBS) is a neurosurgical procedure that utilizes implanted electrodes and electrical stimulation for the treatment of neurological disorders. In cases where patients present with severe functional impairment while being refractory to less invasive treatment options, DBS is considered "gold standard." Still, DBS-related work is still widely under investigation, with ethical issues arising that may impact a patient's physical and psycho-social status. These include patient selection, informed consent, patient autonomy, pre-operation counseling and professional psycho-social preparation and follow-up support. Bioethicists and philosophers have increasingly worked together with in clinicians and researchers to identify, address and present ethical consideration in both clinical practice and research to balance the risk-benefit ratio in DBS treatment for obsessive-compulsive disorder.
