Patients in the vegetative state are wholly unaware of themselves, or their surroundings. However, a minority of patients diagnosed as vegetative are actually aware. What is the well-being of these patients? How are their lives going, for them? It has been argued that on a reasonable conception of well-being, these patients are faring so poorly that it may be in their best interests not to continue existing. I argue against this claim. Standard conceptions of well-being do not clearly support the (...) conclusion that these patients would be better off having life-sustaining treatment withdrawn, and in fact, it may be possible for these patients to retain a passable level of well-being. I suggest that further research into the subjective experiences of these patients will allow us to better promote their well-being. (shrink)

Pain, suffering and positive emotions in patients in vegetative state/unresponsive wakefulness syndrome (VS/UWS) and minimally conscious states (MCS) pose clinical and ethical challenges. Clinically, we evaluate behavioural responses after painful stimulation and also emotionally-contingent behaviours (e.g., smiling). Using stimuli with emotional valence, neuroimaging and electrophysiology technologies can detect subclinical remnants of preserved capacities for pain which might influence decisions about treatment limitation. To date, no data exist as to how healthcare providers think about end-of-life options (e.g., withdrawal of artificial nutrition (...) and hydration) in the presence or absence of pain in non-communicative patients. Here, we aimed to better clarify this issue by re-analyzing previously published data on pain perception (Prog Brain Res 2009 177, 329–38) and end-of-life decisions (J Neurol 2010 258, 1058–65) in patients with disorders of consciousness. In a sample of 2259 European healthcare professionals we found that, for VS/UWS more respondents agreed with treatment withdrawal when they considered that VS/UWS patients did not feel pain (77%) as compared to those who thought VS/UWS did feel pain (59%). This interaction was influenced by religiosity and professional background. For MCS, end-of-life attitudes were not influenced by opinions on pain perception. Within a contemporary ethical context we discuss (1) the evolving scientific understandings of pain perception and their relationship to existing clinical and ethical guidelines; (2) the discrepancies of attitudes within (and between) healthcare providers and their consequences for treatment approaches, and (3) the implicit but complex relationship between pain perception and attitudes toward life-sustaining treatments.

Novel neurotechnologies like deep brain stimulation and brain-computer interfaces promise clinical benefits for severely suffering patients. Nevertheless, such electroceuticals raise several ethical issues on different levels: while on the level of clinical neuroethics issues with direct relevance for diagnosis and treatment have to be discussed, on the level of research neuroethics questions regarding research and development of these technological devices like investigating new targets and different diseases as well as thorough inclusion criteria are dealt with. On the level of theoretical (...) neuroethics more general questions are examined including anthropological considerations on “normal” human functioning as well as implications on personality, personal identity and authenticity. This paper presents a brief review on ethical issues of deep brain stimulation and brain computer interfacing and simultaneously introduces to this themed issue with thirteen contributions dealing from different perspectives with ethical implications of electroceuticals for the human brain.

The locked-in syndrome is a state of profound paralysis with preserved awareness of self and environment who typically results from a brain stem stroke. Although patients in LIS have great difficulty communicating, their consciousness, cognition, and language usually remain intact. Medical decision-making by LIS patients is compromised, not by cognitive impairment, but by severe communication impairment. Former systems of communication that permitted LIS patients to make only “yes” or “no” responses to questions was sufficient to validate their consent for simple (...) medical decisions but not for consequential medical decisions such as whether to refuse further life-sustaining therapy. Emerging technologies including computer-tracking assistance of retained partial motor function and brain-computer interfaces promise to improve the communication ability of LIS patients and, when better developed, will allow them to fully exercise their right to actively participate in consequential medical decisions about their own medical care. Although so-called “covert cognition” patients clinically diagnosed as vegetative state that are shown to be aware by functional neuroimaging maybe metaphorically considered locked-in, it is nosologically more coherent not to categorize them formally as LIS.

New brain-computer interface and neuroimaging techniques are making differentiation less ambiguous and more accurate between unresponsive wakefulness syndrome patients and patients with higher cognitive function and awareness. As research into these areas continues to progress, new ethical issues will face physicians of patients suffering from total locked-in syndrome, characterized by complete loss of voluntary muscle control, with retention of cognitive function and awareness detectable only with neuroimaging and brain-computer interfaces. Physicians, researchers, ethicists and hospital ethics committees should be aware of (...) and prepared to handle ethical issues unique to these totally locked-in patients. Several thought experiments are discussed, to highlight potential ethical dilemmas surrounding surrogate decision-making, autonomy, end-of-life care, and pediatric care, which will be unique to total LIS patients. These, along with other ethical problems especially relevant to total LIS patients, merit further discussion among physicians, researchers, ethicists and hospital ethics committees, to facilitate consensus regarding these issues, and improve patient care.

Recent work in the psychology of happiness has led some to conclude that we are unreliable assessors of our lives and that skepticism about whether we are happy is a genuine possibility worth taking very seriously. I argue that such claims, if true, have worrisome implications for procreation. In particular, they show that skepticism about whether many if not most people are well positioned to create persons is a genuine possibility worth taking very seriously. This skeptical worry should not be (...) confused with a related but much stronger version of the argument, which says that all human lives are very bad and not worth starting. I criticize the latter stance, but take seriously the former stance and hope it can be answered in future work. (shrink)

Patient outcome after serious brain injury is highly variable. Following a period of coma, some patients recover while others progress into a vegetative state (unresponsive wakefulness syndrome) or minimally conscious state. In both cases, assessment is difficult and misdiagnosis may be as high as 43%. Recent advances in neuroimaging suggest a solution. Both functional magnetic resonance imaging and electroencephalography have been used to detect residual cognitive function in vegetative and minimally conscious patients. Neuroimaging may improve diagnosis and prognostication. These techniques (...) are beginning to be applied to comatose patients soon after injury. Evidence of preserved cognitive function may predict recovery, and this information would help families and health providers. Complex ethical issues arise due to the vulnerability of patients and families, difficulties interpreting negative results, restriction of communication to “yes” or “no” answers, and cost. We seek to investigate ethical issues in the use of neuroimaging in behaviorally nonresponsive patients who have suffered serious brain injury. The objectives of this research are to: (1) create an approach to capacity assessment using neuroimaging; (2) develop an ethics of welfare framework to guide considerations of quality of life; (3) explore the impact of neuroimaging on families; and, (4) analyze the ethics of the use of neuroimaging in comatose patients.

Disability might be relevant to decisions about life support in intensive care in several ways. It might affect the chance of treatment being successful, or a patient’s life expectancy with treatment. It may affect whether treatment is in a patient’s best interests. However, even if treatment would be of overall benefit it may be unaffordable and consequently unable to be provided. In this paper we will draw on the example of neonatal intensive care, and ask whether or when it is (...) justified to ration life-saving treatment on the basis of disability. We argue that predicted disability is relevant both indirectly and directly to rationing decisions. (shrink)

The existential situation of persons who suffer from the locked-in syndrome raises manifold issues significant to medical anthropology, phenomenology, biomedical ethics, and neuroethics that have not yet been systematically explored. The present special issue of Neuroethics illustrates the joint effort of a consolidating network of scholars from various disciplines in Europe, North America and Japan to go in that direction, and to explore LIS beyond clinical studies and quality of life assessments.

There is no systematic knowledge about how individuals with Locked-in Syndrome experience their situation. A phenomenology of LIS, in the sense of a description of subjective experience as lived by the ill persons themselves, does not yet exist as an organized endeavor. The present article takes a step in that direction by reviewing various materials and making some suggestions. First-person narratives provide the most important sources, but very few have been discussed. LIS barely appears in bioethics and neuroethics. Research on (...) Quality of Life provides relevant information, one questionnaire study explores the sense of personal continuity in LIS patients, and LIS has been used as a test case of theories in “embodied cognition” and to explore issues in the phenomenology of illness and communication. A systematic phenomenology of LIS would draw on these different areas: while some deal directly with subjective experience, others throw light on its psychological, sociocultural and materials conditions. Such an undertaking can contribute to the improvement of care and QOL, and help inform philosophical questions, such as those concerning the properties that define persons, the conditions of their identity and continuity, or the dynamics of embodiment and intersubjectivity.

Personhood is ascribed on others, such that someone who is recognized to be a person is bestowed with certain civil rights and the right to decision making. A rising question is how severely brain-injured patients who regain consciousness can also regain their personhood. The case of patients with locked-in syndrome is illustrative in this matter. Upon restoration of consciousness, patients with LIS find themselves in a state of profound demolition of their bodily functions. From the third-person perspective, it can be (...) expected that LIS patients might experience a differential personal identity and may lose their status as persons. However, from the patients’ perspective, it is uncontested that they retain their personal identity and that they consider themselves to be persons. We here include results from a survey with patients with LIS aimed at identifying the primary expectations of patients for their care by non-medical professionals. Based on these first-hand reports, we argue that personhood in LIS is progressively regained as the widening circle of others recognizes them as persons. (shrink)
