Deep brain stimulation (DBS) has in some cases been associated with significant psychological effects and/or personality change. These effects occur sometimes as acute changes experienced intraoperatively or during the initial setting of the stimulator and sometimes as longer term progressive changes in the months following surgery. Sometimes they are the intended outcome of treatment, and in other cases they are an unintended side-effect. In all of these circumstances some patients and caregivers have described the psychological effects of DBS as frightening (...) or disconcerting. I trace the source of these negative reactions to the fear that stimulation-related psychological and personality changes represent a threat to personal identity and agency. This issue has implications both for philosophical theories of personal identity and agency and for clinical concerns. A narrative account of personal identity is developed to illuminate the nature of the threat to identity and agency DBS potentially poses, and to suggest steps that might be taken to mitigate and avoid these threats.

How can black feminist and women of color feminist theoretical interventions help create frameworks for discerning agentic action in the context of power, oppression, and violence? In this paper, I explore the social dimension of agency and argue that intention is not just authored by the agent as a function of practical reasoning, but is also socially authored through others' discernment and translation of her action. Further, when facilitated by reasoning designed to reinforce and rationalize systems of domination, social authoring (...) systematically distorts the intentions of some agents. Although some theorists have argued that those agents whose intentions are not recognized by others are forced to exercise a diminished agency, I contend that this account obscures agency that is practiced despite or through conditions of oppression. As an alternative, I propose that feminist of color theory that examines the structural and existential erasures of women of color maps a conceptual space to help us better discern agentic action that is practiced by those subjects whose acts are defined away from them.

This article explores the notion of the dislocated self following deep brain stimulation (DBS) and concludes that when personal identity is understood in dynamic, narrative, and relational terms, the claim that DBS is a threat to personal identity is deeply problematic. While DBS may result in profound changes in behaviour, mood and cognition (characteristics closely linked to personality), it is not helpful to characterize DBS as threatening to personal identity insofar as this claim is either false, misdirected or trivially true. (...) The claim is false insofar as it misunderstands the dynamic nature of identity formation. The claim is misdirected at DBS insofar as the real threat to personal identity is the discriminatory attitudes of others towards persons with motor and other disabilities. The claim is trivially true insofar as any dramatic event or experience integrated into one’s identity-constituting narrative could then potentially be described as threatening. From the perspective of relational personal identity, when DBS dramatically disrupts the narrative flow, this disruption is best examined through the lens of agency. For illustrative purposes, the focus is on DBS for the treatment of Parkinson’s disease. (shrink)

This article probes the philosophical and political significance of the relationships between wheelchair activists and their wheelchairs. Analyzing disability memoirs and the work of a professional wheelchair dancer, I argue that wheelers frequently experience complex relationality and queer kinships with their wheels. By bringing the artistry of disabled writers and dancers into conversation with the notions of human–material relations in the work of Donna Haraway, Jane Bennett, Stacy Alaimo, and Mel Chen, I show how alternative animacies shape wheelers’ conceptions of (...) interdependence and movement. The sensuous pleasure they take in their wheels queers conventional conceptions of how humans should relate to things. New materialist philosophy has increasingly drawn attention to the porous boundaries between the human and material world. But where posthumanist philosophers have largely aimed to dethrone the sovereignty of the human, disability activists use alternative animacies to raise up a devalued and discounted portion of humanity: to emphasize the agency and capacity of those whose lives are often cast as pitiable and powerless, to express a queer feminist disability culture and politics, and to claim the transgressive vitality and vibrant artistry of life with disability.

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.

The phenomenological effects of deep brain stimulation (DBS) on the self of the patient remains poorly understood and under described in the literature, despite growing evidence that a significant number of patients experience postoperative neuropsychiatric changes. To address this lack of phenomenological evidence, we conducted in-depth, semistructured interviews with 17 patients with Parkinson's disease who had undergone DBS. Exploring the subjective character specific to patients' experience of being implanted gives empirical and conceptual understanding of the potential phenomenon of DBS-induced self-estrangement. (...) Our study concluded that (1) the more patients preoperatively felt alienated by their illness, the more they experienced postoperative self-estrangement, and (2) the notion of self-estrangement seems to exist in association with certain common qualitative characters, namely, loss of control, which reflects a deteriorative estrangement, and distorted perception of capacities, which reveals a restorative estrangement. These findings indicate that subjective self-reports help us to understand some aspects of the potential phenomenon of DBS-induced self-estrangement. (shrink)

How can any of my actions genuinely be my own? How can they be more than just intentional performances, with whatever investment of my will that involves, but also belong to me in the special way that makes me autonomous in performing them? How, in other words, can any of my actions be my own in such a way that they arise from or manifest my capacities for self-governance? -/- The literature on autonomous agency employs a number of metaphors to (...) characterize the difference between merely intentional action and action that is, in the fullest sense, the agent's own. Harry Frankfurt's metaphors are among the most vivid and compelling. A person who acts autonomously genuinely “participates” in the operation of her will, as opposed to being “estranged” from herself or being “a helpless or passive bystander to the forces that move” her. Agents who act intentionally but without autonomy do not do what they “really want” to do; their effective volitions are “external to” or “outside” them. The pervasive notion in this literature that persons who are autonomous in acting act upon wills that are fully their own or that really belong to them suggests an initial answer to the questions with which the chapter opened. I am autonomous in acting just when I take ownership of my actions, or at least have the unimpeded capability to take ownership of what I do and regularly exercise that capability. (shrink)

In this article, I explore select case studies of Parkinson patients treated with deep brain stimulation in light of the notions of alienation and authenticity. While the literature on DBS has so far neglected the issues of authenticity and alienation, I argue that interpreting these cases in terms of these concepts raises new issues for not only the philosophical discussion of neuro-ethics of DBS, but also for the psychological and medical approach to patients under DBS. In particular, I suggest that (...) the experience of alienation and authenticity varies from patient to patient with DBS. For some, alienation can be brought about by neurointerventions because patients no longer feel like themselves. But, on the other hand, it seems alienation can also be cured by DBS as other patients experience their state of mind as authentic under treatment and retrospectively regard their former lives without stimulation as alienated. I argue that we must do further research on the relevance of authenticity and alienation to patients treated with DBS in order to gain a deeper philosophical understanding, and to develop the best evaluative criterion for the behavior of DBS patients.

Ethical analyses of the effects of neural interventions commonly focus on changes to personality and behavior, interpreting these changes in terms of authenticity and identity. These phenomena have led to debate among ethicists about the meaning of these terms for ethical analysis of such interventions. While these theoretical approaches have different criteria for ethical significance, they agree that patients’ reports are concerning because a sense of self is valuable. In this paper, I question this assumption. I propose that the Buddhist (...) theory of no‐self offers a novel approach to making ethical sense of patients’ claims following deep brain stimulation. This alternative approach is based on the value of insight into patterns of cause and effect among mental states and actions. (shrink)

While deep brain stimulation (DBS) for patients with Parkinson's disease has typically raised ethical questions about autonomy, accountability and personal identity, recent research indicates that we need to begin taking into account issues surrounding the patients’ feelings of authenticity and alienation as well. In order to bring out the relevance of this dimension to ethical considerations of DBS, I analyse a recent case study of a Dutch patient who, as a result of DBS, faced a dilemma between autonomy and authenticity. (...) This case study is meant to point out the normatively meaningful tension patients under DBS experience between authenticity and autonomy. (shrink)
