Neurotechnologies that are currently applied to treat a range of neurological and psychiatric diseases were found to have a number of positive side effects on cognitive functioning in healthy individuals. Consequently, these neurotechnologies could in theory be used for cognitive enhancement purposes, for instance, the improvement of eyewitness memory. Improving the process of collecting eyewitness testimony would be of great value and is an example of cognitive enhancement for the common good. In this article, we discuss the epistemological and ethical (...) issues such use raises. These issues are not only critical to using neurotechnologies to improve eyewitness memory, but have a wider scope. By discussing enhancement for a purpose that is not primarily self-regarding or self-serving but potentially benefits the society as a whole, we reflect on the consequences of accepting enhancement for the common good for the acceptability of cognitive enhancement in general.

Gilbert et al. argue that the concerns about the influence of Deep Brain Stimulation on – as they lump together – personality, identity, agency, autonomy, authenticity and the self are due to an ethics hype. They argue that there is only a small empirical base for an extended ethics debate. We will critically examine their claims and argue that Gilbert and colleagues do not show that the identity debate in DBS is a bubble, they in fact give very little evidence (...) for that. Rather they show the challenges of doing research in a field that is stretched out over multiple disciplines. In that sense their paper is an important starting point for a discussion on methodology and offers valuable lessons for a future research agenda. (shrink)

Deep Brain Stimulation (DBS) is a treatment involving the implantation of electrodes into the brain. Presently, it is used for neurological disorders like Parkinson’s disease, but indications are expanding to psychiatric disorders such as depression, addiction and Obsessive Compulsive Disorder (OCD). Theoretically, it may be possible to use DBS for the enhancement of various mental functions. This article discusses a case of an OCD patient who felt very happy with the DBS treatment, even though her symptoms were not reduced. First, (...) it is explored if the argument that ‘doctors are not in the business of trading happiness’, as used by her psychiatrist to justify his discontinuation of the DBS treatment, holds. The relationship between enhancement and the goals of medicine is discussed and it is concluded that even though the goals of medicine do not set strict limits and may even include certain types of enhancement, there are some good reasons for limiting the kind of things doctors are required or allowed to do. Next, the case is discussed from the perspective of beneficence and autonomy. It is argued that making people feel good is not the same as enhancing their well-being and that it is unlikely—though not absolutely impossible—that the well-being of the happy OCD patient is really improved. Finally, some concerns regarding the autonomy of a request made under the influence of DBS treatment are considered. (shrink)

In this article, we explore how deep brain stimulation (DBS) devices designed to “close the loop”—to automatically adjust stimulation levels based on computational algorithms—may risk taking the individual agent “out of the loop” of control in areas where (at least apparent) conscious control is a hallmark of our agency. This is of particular concern in the area of psychiatric disorders, where closed-loop DBS is attracting increasing attention as a therapy. Using a relational model of identity and agency, we consider whether (...) DBS designed for psychiatric regulation may require special attention to agency. To do this, we draw on philosophical work on relational identity and agency, connecting it with reports from people using first-generation DBS devices for depression and obsessive-compulsive disorder. We suggest a way to extend a notion of relational agency to encompass neural devices. (shrink)

This paper explores the impacts of neurological intervention on selfhood with reference to recipients’ claims about changes to their self-understanding following Deep Brain Stimulation for treatment of Parkinson’s Disease. In the neuroethics literature, patients’ claims such as: “I don’t feel like myself anymore” and “I feel like a machine”, are often understood as expressing threats to identity. In this paper I argue that framing debates in terms of a possible threat to identity—whether for or against the proposition, is mistaken and (...) occludes what is ethically salient in changes from DBS. Rather, by adopting a relational narrative approach to identity and autonomy, I show that the ethically salient issue from DBS is impacts on autonomous agency—whether one’s actions and beliefs are one’s own, and how DBS may hinder, or foster, embodied, relational autonomy competences. This approach recognizes that if sufficiently significant, impacts on autonomy competences may pose a threat to one’s ability to contribute to the process of authoring one’s own life and so pose a threat to identity formation. I argue this approach resolves the confusion in the literature about whether and how DBS threatens identity and provides a complex picture of how DBS may affect selfhood by disrupting narrative identity formation and revision, distorting agency and/or undermining autonomy.

Questions about the nature of self and self-consciousness are closely aligned with questions about the nature of autonomy. These concepts have deep roots in traditional philosophical discussions that concern metaphysics, epistemology and ethics. They also have direct relevance to practical considerations about informed consent in medical contexts. In this paper, with reference to understanding specific side effects of deep brain stimulation treatment in cases of, for example, Parkinson’s Disease, Obsessive Compulsive Disorder, and Major Depressive Disorder, I’ll argue that it is (...) best to frame discussions of informed consent in terms of relational autonomy and a pattern theory of self.

One of the reasons why moral enhancement may be controversial, is because the advantages of moral enhancement may fall upon society rather than on those who are enhanced. If directed at individuals with certain counter-moral traits it may have direct societal benefits by lowering immoral behavior and increasing public safety, but it is not directly clear if this also benefits the individual in question. In this paper, we will discuss what we consider to be moral enhancement, how different means may (...) be used to achieve it and whether the means we employ to reach moral enhancement matter morally. Are certain means to achieve moral enhancement wrong in themselves? Are certain means to achieve moral enhancement better than others, and if so, why? More specifically, we will investigate whether the difference between direct and indirect moral enhancement matters morally. Is it the case that indirect means are morally preferable to direct means of moral enhancement and can we indeed pinpoint relevant intrinsic, moral differences between both? We argue that the distinction between direct and indirect means is indeed morally relevant, but only insofar as it tracks an underlying distinction between active and passive interventions. Although passive interventions can be ethical provided specific safeguards are put in place, these interventions exhibit a greater potential to compromise autonomy and disrupt identity. (shrink)

Neuromodulation and narrative identity: the importance of relational autonomyIn this paper, I discuss the impact of psychological and relational changes after neuromodulation for movement- and psychiatric disorders and the need to adequately address the possibility of such changes in clinical contexts. Based on ), ) and ), I outline a relational narrative identity perspective that can inform and support medical-ethical decisions. The narrative identity theory by Marya Schechtman in combination with a focus on the relational aspects that impact and constitute (...) our identity, highlights the need to identify post-interventional identity changes both from the perspective of the patient, his or her family and loved ones and the medical team. I argue that a thorough informed consent process pre- and post-intervention and adequate psychological counseling allows for such identification and a step by step monitoring and guiding of the patient in this process. From a relational narrative perspective, neuromodulation does not by default pose a threat to our identity. However, this perspective highlights the need to take the relational autonomy of patients seriously and provide a substantial informed consent procedure and adequate psychological counseling.

The article proposes a theoretical model to account for changes in self due to Deep Brain Stimulation. First, we argue that most existing models postulate a very narrow conception of self, and thus fail to capture the full range of potentially relevant DBS-induced changes. Second, building on previous work by Shaun Gallagher, we propose a modified ‘pattern-theory of self’, which provides a richer picture of the possible consequences of DBS treatment.

Mecacci and Haselager's (2014) proposal is to reduce maladaptation after DBS treatment by revising the patient's conceptual scheme of the self. We are sympathetic to such an approach, but we want t...
