Examining the potential bioethical issues with deep brain stimulation in patients with Parkinson’s Disease

Recent research has suggested a significant decrease in Parkinson’s disease motion symptoms after early deep brain stimulation (DBS). This discovery could lead to a significant increase in quality of life and duration of effective treatment. However, there have been many accounts of patients who experience personality changes such as increased impulsivity after DBS. This work will examine the bioethical issues presented with DBS in patients with Parkinson’s disease and re-evaluate the five broad ethical questions relevant to clinical ethics in the application of DBS.
