Dementia patients in the moderate-late stage of the disease can, and often do, express different preferences than they did at the onset of their condition. The received view in the philosophical literature argues that advance directives which prioritize the patient’s preferences at onset ought to be given decisive moral weight in medical decision-making. Clinical practice, on the other hand, favors giving moral weight to the preferences expressed by dementia patients after onset. The purpose of this article is to show that (...) the received view in the philosophical literature is inadequate and is out of touch with real clinical practice. I argue that having dementia is a cognitive transformative experience and that preference changes which result from this are legitimate and ought to be given moral weight in medical decision-making. This argument ought to encourage us to reduce our confidence in the moral weight of advance directives for dementia patients. (shrink)

In the future, policies surrounding end-of-life decisions will be faced with the question of whether competent people in a completely locked-in state should be enabled to make end-of-life decisions via brain-computer interfaces (BCI). This article raises ethical issues with acting through BCIs in the context of these decisions, specifically self-administration requirements within assisted suicide policies. We argue that enabling patients to end their life even once they have entered completely locked-in state might, paradoxically, prolong and uphold their quality of life.

This paper critically examines whether patients with severe brain injury, who can only communicate through assistive neuroimaging technologies, may permissibly participate in medical decisions. We examine this issue in the context of a unique case study from the Brain and Mind Institute at the University of Western Ontario. First, we describe how the standard approach to medical decision making might problematically exclude patients with communication impairments secondary to severe brain injury. Second, we present a modified approach to medical decision making. (...) We argue that this approach might warrant the inclusion of some patients with severe brain injury in low-stakes decisions, or to express preferences. Third, we present a model of supported decision making to address recalcitrant uncertainty. We conclude by suggesting that the modified approach to decision making and supported decision making might allow a patient with severe brain injury to participate in some medical decisions. Our analysis is provisional and has not yet been implemented in practice. Our discussion is intended to generate further debate on approaches to enhancing autonomy in patients with profound motor and cognitive impairments. (shrink)

In this article, I present an argument that suggests neuroscience should inform judgments of decision-making capacity. First, I review key behavioral and neurocognitive data to demonstrate that neuroscientific tests might be predictive of decision-making capacity, and that these tests might inform clinical judgments of capacity. Second, I argue that, consistent with the principles of autonomy and justice, such data should inform judgements of decision-making capacity. While the neuroscience of decision-making capacity still requires time to mature, there is strong reason to (...) believe that neuroscience might assist clinicians in adjudicating difficult cases in the future. This article focuses on the assessment of capacity in brain injury patients who have profound communication impairments, however, the overarching aim of the article is to highlight the potential use of neuroscience to improve our understanding of the relationship between cognition and decision-making capacity.

:In this paper, the author argues that Joseph Fins’ mosaic decisionmaking model for brain-injured patients is untenable. He supports this claim by identifying three problems with mosaic decisionmaking. First, that it is unclear whether a mosaic is a conceptually adequate metaphor for a decisionmaking process that is intended to promote patient autonomy. Second, that the proposed legal framework for mosaic decisionmaking is inappropriate. Third, that it is unclear how we ought to select patients for participation in mosaic decisionmaking.

Berger (2019) argues effectively that “representativeness is more aptly understood as a variable that is multidimensional and continuous based on relational moral authority,” and also makes some useful suggestions about how taking this observation seriously might require changes in current patterns of practice regarding surrogates. But the essay raises additional important questions about how the Best Interest Standard (BIS) should be used among unrepresented patients and other patients as well because many surrogates besides those who “have no actionable knowledge of (...) a patient’s preferences” find themselves in positions in which they need to determine, with the physician, what is in the patient’s best interests. In this commentary, we therefore provide support for the ethical superiority of BIS judgments made by a multi-stakeholder process (rather than solo decision-makers), and sketch a process by which such judgments might be made.

Deep Brain Stimulation is an FDA-approved treatment for the symptoms of Parkinson's disease, essential tremor, dystonia, and epilepsy—with experimental use for mood disorders. DBS systems consist of a signal generator, typically implanted in the user's chest, that sends impulses to electrodes implanted in select areas of the user's brain. These signals change the activity of areas of the brain associated with unwanted symptoms. Several research groups have begun trials to use DBS as a treatment for psychiatric disorders. DBS, however, comes (...) with a... (shrink)
