Deep brain stimulation interventions are novel devices being investigated for the management of severe treatment-resistant psychiatric illnesses. These interventions require the invasive implantation of high-frequency neurostimulatory probes intracranially aiming to provide symptom relief in treatment-resistant disorders including obsessive-compulsive disorder and anorexia nervosa. In the scientific literature, these neurostimulatory interventions are commonly described as reversible and to be used as a last resort option for psychiatric patients. However, the ‘last resort’ status of these interventions is rarely expanded upon. Contrastingly, usages of (...) DBS devices for neurological symptoms have paved the way for established safety and efficacy standards when used earlier in a disease’s timeline. As DBS treatments for these neurological diseases progress to have earlier indications, there is a parallel ethical concern that early implementation may one day become prescribed for psychiatric illnesses. The purpose of this article is to build off contemporary understandings of reversible neurostimulatory interventions to examine and provide clarifications on the ‘last resort’ status of DBS to better address its ethically charged use in psychiatric neurosurgery. To do this, evaluative differences between DBS treatments will be discussed to demonstrate how patient autonomy would be a paramount guiding principle when one day implementing these devices at various points along a psychiatric disease’s timeline. In presenting the clarification of ‘last resort’ status, the ethical tensions of early DBS interventions will be better understood to assist in providing psychiatric patients with more quality of life years in line with their values.

It is widely accepted that children enjoy some form of a right to bodily integrity. However, there is little agreement about the precise nature and scope of this right. This paper offers a conceptual analysis of the child's right to bodily integrity, in order to further elucidate the relationship between the child's right to bodily integrity and considerations of autonomy. Following a discussion of Leif Wenar's work on the structure and justification of rights, I first explain how the adult's right (...) to bodily integrity can be distilled into separate elements that may plausibly be justified by different moral considerations. In particular, I claim that this analysis suggests that whilst the adult's right to bodily integrity is not wholly reducible to bodily autonomy, autonomy nonetheless remains entwined with our understanding of this right in a number of ways. On the basis of this discussion, I go on to outline three important complexities that arise when we consider the child's right to bodily integrity, before particularly focusing on the question of how third parties should determine whether or not to perform a physical interference upon a child who lacks decision-making capacity. Here, I raise some objections to Earp and Mazor's recent attempts to answer this question, before briefly defending an ‘autonomy-based interests’ account of permissible interference, an account that shares in what I take to be the spirit, if not the precise letter, of these earlier views.

There is evidence to suggest that some patients who undergo Deep Brain Stimulation can experience changes to dispositional, emotional and behavioural states that play a central role in conceptions of personality, identity, autonomy, authenticity, agency and/or self. For example, some patients undergoing DBS for Parkinson’s Disease have developed hypersexuality, and some have reported increased apathy. Moreover, experimental psychiatric applications of DBS may intentionally seek to elicit changes to the patient’s dispositional, emotional and behavioural states, in so far as dysfunctions in (...) these states may undergird the targeted disorder. Such changes following DBS have been of considerable interest to ethicists, but there is a considerable degree of conflict amongst different parties to this debate about whether DBS really does change PIAAAS, and whether this matters. This paper explores these conflicting views and suggests that we may be able to mediate this conflict by attending more closely to what parties to the debate mean when they invoke the concepts lumped together under the acronym PIAAAS. Drawing on empirical work on patient attitudes, this paper outlines how these different understandings of the concepts incorporated into PIAAAS have been understood in this debate, and how they may relate to other fundamental concepts in medical ethics such as well-being and autonomy. The paper clarifies some key areas of disagreement in this context, and develops proposals for how ethicists might fruitfully contribute to future empirical assessments of apparent changes to PIAAAS following DBS treatment.

The debate about how neurotechnologies impact authenticity has focused on two inter-related dimensions: self-discovery and self-creation. In this paper, we develop a broader framework that includes the experimental and relational dimensions of authenticity, both understood as decisive for shaping one’s narrative identity. In our view, neurointerventions that alter someone’s personality traits will also impact her very own self-understanding across time. We argue that experimental authenticity only needs a minimum conception of narrative coherence of the self and that reversibility should remain (...) a key feature in the ethical assessment of neurotechnologies. The relational dimension of authenticity derives from the fact that a process of self-constitution is never a solitary business. The significant others act not just as subsequent judges of one’s life decisions, but as real co-authors of one’s self. We discuss relevant cases in which others are actively contributing to the meaning-making process, as to the direction one’s life is taking. We also claim that the experimental and the relational dimensions of authenticity should aim to correct each other. The relational dimension introduces socially approved standards as well as limitations to the array of available possibilities of self-fashioning or human enhancement. The experimental side enables us to avoid confusing one’s personal identity with a social and narrative construct that only bears the mark of social pressure and conformism. (shrink)

Moral agential neuroenhancement can transform us into better people. However, critics of MB raise four central objections to MANEs use: It destroys moral freedom; it kills one moral agent and replaces them with another, better agent; it carries significant risk of infection and illness; it benefits society but not the enhanced person; and it’s wrong to experiment on nonconsenting persons. Herein, I defend MANE’s use for prisoners of war fighting unjustly. First, the permissibility of killing unjust combatants entails that, in (...) cases where MANE is equally or more likely as termination to reduce moral recidivism in unjust combatants, then MANE is morally justified. Second, the relevant infections and illnesses caused by MANE are less bad than death, so MANE leaves unjust POWs better off than the alternative. Third, just as incarceration is often permissible despite benefitting society but not the incarcerated, the same holds for unjust POWs. Fourth, we should accept a broader construal of “benefit” that includes moral benefits. Thus, 3 and 4 are false when applied to unjust POWs. Fifth, medical experimentation likely to help nonconsenting persons is sometimes permissible. Because MANE is likely to help unjust POWs irrespective of their consent or lack thereof, its use is permissible. Sixth, basic principles of proper medical care support the use of MANE on unjust POWs as pro tanto morally obligatory. I conclude that militaries should therefore begin to employ MANE for unjust POWs. (shrink)

A key objective of the law in the assessment of decision-making capacity in clinical settings is to allow clinicians and judges to avoid making value judgements about the reasons that patients use to refuse treatment. This paper advances two lines of argument in respect of this objective. The first is that authorities cannot rationally avoid significant evaluative judgements in the assessment of a patient’s own assessment of the facts of their case. Assessing reasoning is unavoidably value-laden. Yet the underlying motivation (...) behind clinicians’ and the law’s value-neutral aims, ie, the avoidance of undue paternalism, is worth preserving. That being so, the second line of argument will try to show that that underlying motivation is better served in a limited range of cases by embedding a ‘reversibility standard’ in the assessment process so that the patient can, if they wish, and in due course, bring about the consequences that they were prevented from realising as a result of a determination of incapacity.

Deep brain stimulation has been regarded as an efficient and safe treatment for Parkinson’s disease since being approved by the Food and Drug Administration in 1997. It is estimated that more than 150 000 patients have been implanted, with a forecasted rapid increase in uptake with population ageing. Recent longitudinal follow-up studies have reported a significant increase in postoperative survival rates of patients with PD implanted with DBS as compared with those not implanted with DBS. Although DBS tends to increase (...) life expectancy for most patients with PD, this medical benefit does not come without attendant negative consequences. For example, emerging forms of iatrogenic harms are sometimes induced—harms which were not initially expected when clinicians proposed neurosurgery and patients or their guardians consented to the treatment. We report and discuss the clinical case of a patient who was implanted with DBS more than 20 years ago and is now experiencing unexpected stages of PD. This case illustrates how extending the life span without improving quality of life may introduce a burden of harms for patients and families. As well, this case shows why we should prepare for the expanding numbers of PD-implanted patients experiencing a gain of longevity but with severe stages of disease leading to diminution in quality of life. This newly observed effect of DBS treatment requires us to explore ethical questions related to iatrogenic harms, informed consent, end of life and caregivers’ burden. (shrink)

Deep brain stimulation (DBS) is an approved treatment for neurological diseases and a promising one for psychiatric conditions, which may produce spectacular results very quickly. It is also a powerful tool for brain research and exploration. Beyond an overview of the ethical and legal literature on this topic, this paper aims at showing that DBS is a compelling example for ethical-legal reflection, as it combines a highly technical surgical procedure, a complex active medical device and neuromodulation of the human brain (...) to restore lost abilities caused by a chronic and evolving disease. Some of the ethical and legal issues raised by DBS are not specific, but shed new light on medical ethics and law. Others are more DBS-specific, as they are linked to the intricacies of research and treatment, to the need to tune the device, to the patients’ control over the device and its effects and to the involvement of family caregivers.
