Track 43: Neurosurgery and Ethics of Performance Enhancement

In a cutting-edge neurosurgical facility, a neurosurgeon, Dr. Laura Bennett, is approached by a 35-year-old, healthy individual, John, a high-performing executive who works long hours in a high-stakes business environment. John expresses interest in undergoing Deep Brain Stimulation (DBS), a procedure originally developed for Parkinson’s disease and major depressive disorder, to enhance his cognitive abilities—specifically improving his focus, memory, and overall cognitive performance. He believes that DBS could provide him with a competitive edge in his professional career and help him manage the increasing demands of his job.

Dr. Bennett is a highly skilled neurosurgeon, known for her expertise in neurostimulation techniques. While DBS has been shown to have profound effects on patients with neurological disorders, the procedure has never been performed on a healthy individual for purely enhancement purposes. As such, she is unsure how to approach John’s request.

Ethical Issues

This case raises multiple ethical concerns:

1. Medical Necessity vs. Enhancement

   • Issue: DBS is generally reserved for patients with serious neurological conditions like Parkinson’s disease or chronic depression. The procedure is intended to alleviate suffering and restore lost function. John, however, is a healthy individual seeking enhancement, not treatment for a medical condition. The question arises: Should neurosurgeons intervene in the absence of medical necessity, particularly for cognitive enhancement?
   • Ethical Consideration: The ethical principle of beneficence (doing good) must be weighed against the potential risks of a procedure designed for therapeutic purposes but applied in an enhancement context. This also raises concerns about the potential for medicalization of normal human functioning, where interventions are sought for non-diseased individuals to optimize traits like intelligence and productivity.

2. Informed Consent

   • Issue: John’s request involves a high-risk surgical procedure, and there is limited evidence on the long-term effects of DBS on healthy individuals. Dr. Bennett must ensure that John understands the potential risks, uncertainties, and lack of definitive evidence supporting the procedure's effectiveness in non-medical contexts.
   • Ethical Consideration: The principle of autonomy requires that John makes an informed decision about his health. This includes fully understanding the potential side effects, such as changes in personality, mood alterations, or cognitive impairment. It is essential for Dr. Bennett to ensure that John is not coerced into the decision by societal pressures to perform at an elite level.

3. Safety and Long-Term Risks

   • Issue: DBS involves implanting electrodes in the brain and carries significant risks, including infection, bleeding, and changes in cognition or behavior. The effects of DBS on healthy individuals—especially for cognitive enhancement purposes—are not well understood.
   • Ethical Consideration: The principle of non-maleficence (do no harm) is central to this case. Neurosurgeons must carefully evaluate whether the potential benefits of cognitive enhancement outweigh the risks of surgery, particularly when the long-term consequences are uncertain.

4. Equity and Access

   • Issue: If DBS for enhancement becomes more common, there may be concerns about access. Only individuals with significant financial resources may be able to afford such procedures, exacerbating social inequalities.
   • Ethical Consideration: The principle of justice demands that healthcare resources be distributed equitably. If cognitive enhancement procedures are restricted to those with access to private healthcare, there could be increased disparity between socioeconomic classes. Moreover, this could lead to the development of a “cognitive elite,” further widening existing societal divides.

5. Slippery Slope: Societal Implications

   • Issue: If DBS is deemed acceptable for enhancement purposes in healthy individuals, this could set a precedent for further medical interventions aimed at augmenting human abilities—potentially leading to a future where human traits such as intelligence, creativity, or even personality could be “optimized” through surgery or genetic interventions.
   • Ethical Consideration: This case raises concerns about the slippery slope argument, where permissibility in one case could lead to increasingly broad applications of medical enhancement. This could result in societal pressures to enhance individuals for non-medical reasons and could redefine what it means to be human.

Ethical Analysis

1. Beneficence vs. Enhancement: Dr. Bennett must carefully evaluate whether performing DBS for enhancement serves the overall well-being of the patient or society. While cognitive enhancement could provide benefits for John’s career, it might not be justifiable in the absence of a medical need. The procedure carries risks that could result in unintended negative outcomes, which might outweigh the potential benefits. Medical enhancement may be perceived as a “luxury” for the privileged few, rather than a necessary intervention for improving quality of life.

2. Informed Consent: Dr. Bennett must provide John with a clear explanation of the potential risks, including the unknown long-term consequences. A thorough discussion should take place about the ethical concerns surrounding performance enhancement, allowing John to make an informed decision about whether to proceed with DBS. Additionally, there should be an emphasis on making sure John’s decision is free of coercion, meaning he should feel no undue pressure from societal or professional expectations.

3. Non-Maleficence and Safety: Given that the effects of DBS on healthy individuals are largely unknown, Dr. Bennett has a responsibility to ensure that John is fully aware of the risks. Even if the procedure offers cognitive benefits, any potential harm must be carefully weighed. If John is not experiencing a medical condition, the ethical question arises: Is it justifiable to expose him to the inherent risks of a procedure that may not be fully proven in a healthy brain?

4. Equity and Justice: The decision to allow DBS for enhancement in healthy individuals might lead to increased inequality in society. If such procedures become mainstream, only wealthy individuals may have access to them, potentially creating a two-tiered society where cognitive abilities and productivity are optimized only for the privileged. Dr. Bennett must consider these broader societal implications before performing any enhancements.

5. Slippery Slope and Societal Implications: If the line between treatment and enhancement becomes blurred, it may lead to an increasing demand for non-therapeutic medical interventions to improve human traits. Neurosurgeons may be faced with growing ethical pressure to perform enhancements that are not medically necessary, leading to potential societal and cultural shifts that could redefine what is considered “normal.”
