Chapter 107 Ethical Issues in Child Neurology
Introduction
The “task” of ethics in general is to understand how human beings should behave in regard to other persons and to society [Slote, 1995] or to understand what is right and what is wrong. The philosophical study of ethics is as old as civilization itself and parallels the growth and development of human society. Morality is understood as the set of generally accepted rules and guidelines for acceptable conduct in society. These social conventions about what is right and wrong constitute the “common morality” [Beauchamp and Childress, 2001]. Philosophical ethics can be thought of as the attempt to develop a rational basis for morality. Although ethics (as a form of philosophy) strives for universal truth, it is inextricably linked to the realities of the human societies whose morality it seeks to understand [Slote, 1995]. Distinguishing between “moral” and “ethical” behavior is often difficult [Bernat, 2008]. Perhaps moral behavior may be thought of as a personal attempt to conduct one’s life in conformity with the common morality, whereas ethical behavior may be thought of as a more theoretical or rational attempt to apply philosophical thinking to what is right and wrong. In other words, ethics is a systematic attempt to understand how to live and act morally in a social context.
Ethics addresses all aspects of human behavior. Bioethics considers the interaction between biology and ethics. It is defined as “the systematic study of the moral dimensions of the life sciences and health care,” and includes consideration of “the health-related and science-related moral issues in the areas of public health, environmental health, population ethics and animal care” [Reich, 1995]. Clinical ethics is a subcategory of bioethics that refers to the day-to-day moral decision-making of those caring for patients [Callahan, 1995]. More specifically, clinical ethics refers to the identification, analysis, and resolution of moral problems that arise in the care of a particular patient [Jonsen et al., 2010]. Medical ethics is a subcategory of clinical ethics that refers to the moral behavior of physicians (and is thus distinguishable from nursing ethics, social work ethics, and pastoral ethics).
Neuroethics is a concept that cuts across most of these distinctions [Illes, 2005]. As an area of bioethics, it considers the interaction between the neurosciences and ethics in all of the same areas of study as for bioethics, noted previously [Pfaff, 1983]. As a clinical discipline, it addresses the care of patients with neurologic disorders. As an area of medical ethics, it refers most directly to the moral behavior of neurologists and neurosurgeons. Thus, child neurologists interested in ethics need to be knowledgeable about the general approaches to ethics, the emerging scope of bioethics, and the more specific approaches to ethics in medicine, nursing, and other health-related disciplines.
Although many articles and books have been published on ethical topics of interest to child neurologists, few provide a systematic approach to ethics in child neurology. A recent collection of articles covered a number of important topics [Shevell, 2002a], and a casebook presented a number of illustrative cases whose analyses illuminate many of the important ethical issues in child neurology [Freeman and McDonnell, 2001]. The best general, systematic resource on ethics in neurology is the classic text by Bernat [2008], but it mainly covers topics of interest in adult neurology. A recent collection of essays on pediatric bioethics, edited by a child neurologist, covered a number of topics of interest to child neurologists [Miller, 2010]. This chapter follows the general structure of Bernat’s book and seeks to apply its concepts specifically to the area of pediatric neurology. The goal of the chapter is to provide child neurologists interested in ethics with the tools they need to identify, analyze, and resolve moral problems they may encounter in the care of children and adolescents with neurologic disorders.
Theoretical Approaches to Ethics
Philosophy may be a search for truth, but the fact is that there is no one, true, universal approach to ethics. Physicians who want to act ethically should be aware of the several major ethical theories that compete for attention in contemporary medical practice. Two ethical theories in particular dominate thinking in Western philosophy. Utilitarianism is derived from the writings of Jeremy Bentham [Bentham, 1982] and John Stuart Mill [Mill, 1971]. Deontology is derived mainly from the writings of Immanuel Kant [Kant, 1959]. Elements of both theories persist in modern ethical approaches to clinical problems, usually in somewhat modified form. Most physicians will find themselves using utilitarian thinking on some occasions and deontologic thinking on other occasions, or using some combination of both when it is necessary to resolve an ethical dilemma in clinical practice.
Utilitarianism
The essence of utilitarian theory is the idea that the morality of an action is determined mainly by its consequences: the morally right action is the one that produces the best result [Beauchamp and Childress, 2001]. Of course, the result of an action may be quite complex. An action that helps one person may harm another person. Withdrawing support from a child in a vegetative state undoubtedly harms the child, since it results in the child’s death, but the action may help the family grieve and may allow society to use limited medical resources to help other patients. The utility principle states that one should act to produce the best overall balance of positive and negative consequences of the act. This idea is embedded in the concept of balancing risks and benefits to achieve the best overall result.
Utilitarian thinking is almost intuitive in many aspects of ordinary life. Understanding this form of thinking is important because it may help avoid the potential pitfalls that can result from uncritical application of the theory. Perhaps the most familiar situation is the use of utilitarian theory to justify the killing of defective newborns [Kuhse and Singer, 1985]. Although theoretically logical, such arguments are morally repugnant to persons who apply a different moral standard based on some other approach to ethics. Another problem with utilitarian theory is its failure to protect minorities, which results from its emphasis on producing the most good for the majority. The needs of children with rare neurologic disorders can be overlooked if utilitarian thinking allocates scarce medical resources primarily to children with more common disorders.
Deontology
Deontologic theory is based on the importance of “deon,” or duty. Duty is based more on the intentions that lead a person to act than on the outcomes or consequences of the action. Utilitarian thinking is mostly situational and depends on the specific aspects of a given situation; deontologic thinking strives to be more universal and to emphasize decisions that would apply in all relevant situations. Thus, Kant’s categorical imperative states that we should act only in a way that is consistent with a universal law or obligation [Kant, 1959]. Using people as means to an end implies that different actions (or reactions) are needed, depending on the end or outcome that is desired; therefore, the actions are not universally applicable. For this reason, deontologic thinking stipulates that we should treat all people as “ends” and not as means to an end. This could cause problems in thinking about the morality of organ transplantation if the organ donor is thought of only as a means to the end of survival for the recipient. Clearly, deontologic thinking imposes a duty to respect the rights and value of the donor as much as those of the recipient because anyone could be either a donor or a recipient.
Common Morality and Natural Law
What are the universal rules that spring from deontologic thinking? Most Western philosophers would argue that these rules can be derived from the application of reason – from rational, logical thinking about the nature of human existence. The general argument is that “all rational persons would agree that these rules are essential to govern and guide the moral actions of individuals in a cohesive society” [Beauchamp and Childress, 2001]. Beauchamp and Childress [2001] describe the “common morality” as socially approved norms of human conduct that form the basis of ethical theory. This common-sense understanding of what is needed for individuals to behave in society is not derived from theory, but rather forms the basis for potentially competing theories.
Natural law theory is an ancient approach to deriving universal rules through the application of reason [Simon, 1992]. For Thomas Aquinas, natural law sprang from man’s participation in God’s eternal law and was brought into being by the application to action of human intelligence and reasoning [May, 1994]. This application leads first to the principle that all things desire that which is good; therefore, good is to be pursued and evil is to be avoided. Good things are those to which man has a natural inclination, such as life (existence), social interaction, family life, and civil government. To pursue these good things, one should act fairly, love God, and love other persons. Secondary precepts or rules (such as the Ten Commandments) follow from these basic principles.
Secular interpretations of natural law are as old as Aristotle and are still used in some forms of legal theory. Bernard Gert [2002] defined two sets of rules that he believed all rational persons would accept as natural and essential, without relying explicitly on natural law theory. Many of his rules are in fact similar to the Ten Commandments. Gert also emphasized that the rules are not absolute and that violations may be considered in specific circumstances. Beauchamp and Childress [2001] do not define any specific rules as part of their common morality, but they do define four principles that are not absolute and that need to be specified based on actual circumstances. None the less, their four principles may be seen to correlate with the precepts of natural law:
Principlism
Principlism is an approach to ethical problems that is based on the application of the four principles of beneficence, nonmaleficence, justice, and autonomy. It is more of a practical guide than an abstract theory, and it has found widespread acceptance in a variety of settings [Beauchamp and Childress, 2001]. It was adopted explicitly in the Belmont Report, which forms the foundation for research ethics in the United States [Belmont Report, 1979]. Although principlism is perhaps the best-known approach to clinical ethical problems, it is by no means the only approach. Understanding principlism is necessary to consider these alternative systems.
The principle of beneficence encourages physicians to do good or to act in the best interest of the patient whenever possible. This principle can also be interpreted to suggest that physicians should seek to promote an optimal quality of life or satisfaction with life. Considerable debate exists about how to measure quality of life [Bowling, 2004; Nordenfelt, 1994; Nussbaum and Sen, 1993; Schalock, 1996]. Objective measures are based on the judgments of others, whereas subjective measures are based on the opinions of the patient about what constitutes a satisfying life. In general, preference is given to subjective judgments when they can be known.
The principle of nonmaleficence encourages physicians to avoid doing harm to patients and dates back to Hippocrates. It is related logically to the principle of beneficence. Both principles are considered when physicians attempt to strike a balance between providing a benefit for the patient (doing good) and not imposing a burden (avoiding harm). This balance may become especially problematic when the same action could produce a good, or desired, effect, as well as a bad, or undesired, effect. The classic example is prescription of sufficient medicine to reduce pain while knowing that it may also cause the patient to stop breathing. This problem is known as the “situation of double effect” [Beauchamp and Childress, 2001]. In Catholic moral theory (which contains the most explicit analysis of such situations), an action that causes double effects is morally justifiable only if it meets all of the following criteria:
The principle of justice requires that equals be treated equally, but the basis for an equal distribution of resources may be arguable. Should resources be distributed according to need, effort, merit, contribution to society, or some other factor? Utilitarian, libertarian, communitarian, and egalitarian approaches have been proposed to answer this question [Beauchamp and Childress, 2001]. Rawls [1971] suggests that resources should be distributed to ameliorate the effects of life’s natural and social lotteries. It may be simply bad luck (“losing the lottery”) that a child is born with a disabling condition or is born into poverty. If the child is not responsible for this condition, then society should act to remedy the situation. According to this rule, unfair situations would presumably have priority over merely unfortunate situations. How many resources should be provided to those who have been unfairly deprived? The limits of this redistribution policy may be the extent to which it disables or impoverishes the rest of society [Veatch, 1986].
Jonsen et al. [2010] suggest that ethical issues can be analyzed by asking the following four questions (which are, in fact, practical applications of the four principles discussed previously):
Virtue or Character Ethics
The catalog of virtues is not exhaustive and varies from one writer to another. Pellegrino and Thomasma [1993] suggest eight virtues that are necessary for sound medical practice:
Ethics of Care
Care-based ethical thinking is prominent in nursing practice but may be somewhat unfamiliar to physicians. It arose as somewhat of an alternative to deontologic, rule-based thinking that depends on adherence to more or less rigid principles. It also arose from feminist research studies comparing male and female approaches to ethical dilemmas. Gilligan [1982] found that males were more likely to look for rules to follow and to insist on adherence to these rules. Females were more likely to look for some situation-based way to resolve a dilemma, taking into consideration the person’s feelings and significant relationships [Gilligan, 1982]. This “feminine” way is not exclusively reserved for women (or for nurses), of course. Rather, it provides an alternative and perhaps more subjective way to evaluate an ethical problem that is especially relevant when a rule-based approach seems to be inappropriate or unhelpful [Held, 2006; Kuhse, 1997; Taylor and Watson, 1989].
Casuistry
Casuistry, or case-based ethics, is another alternative to utilitarian or rule-based ethical approaches [Jonsen and Toulmin, 1988]. It rejects the very idea of a “moral calculus” that can be analyzed impartially, based on abstract concepts. Instead of a “top-down” approach, based on pure theory, it takes a “bottom-up” approach, based on the particularity of specific cases. Casuistry looks at specific cases and emphasizes points of agreement about those cases. It recognizes that moral intuition may be more important than adherence to principles. It is common knowledge that members of hospital ethics committees often agree on what needs to be done but cannot always say with clarity why they feel that way (or what ethical theory they relied on to make a particular judgment). This moral intuition may also reflect the influence of the “common morality” described previously. By looking at the particularities of a specific case, casuistry is also sensitive to contextual influences and individual differences.
Spirituality
Spirituality is variously defined, but it can be understood as a belief system that focuses on intangible elements that impart vitality and meaning to one’s life [Koenig, 2002]. Because it is based on beliefs, or faith statements, it is not provable through logical argument. Spirituality in medicine is often based on religious beliefs [Sulmasy, 1997], but it need not be. As an expression of ultimate concern, it reflects the elements of our lives that are the most important and make life worth living. Most people have some spiritual beliefs that become prominent when their health is threatened; yet these beliefs are often not considered by physicians and other health-care providers. Physicians may anticipate that patients would have certain beliefs based on knowledge of their religious background [Numbers and Amundsen, 1998], but individual differences exist, even within a religious tradition. A more direct understanding of the patient’s spirituality would be preferable.
One approach to understanding the patient’s spirituality is the “three ways of looking” [Coulter, 2001]. The first look is to see the person subjectively as an individual human being. Compassion requires distance and objectivity [Pellegrino and Thomasma, 1993], but this first look requires closeness and subjectivity. It is an attempt to understand the patient’s spiritual beliefs. The second look is to recognize in the other person that which we know to be central to our own existence. With the second look, we can value in the patient that which we most value in ourselves. These values include living, freedom, tolerance, respect, happiness, and satisfaction with life. Physicians would then seek to protect for their patients the values that they would protect for themselves. The third look is more elusive and is an attempt to grasp, through our relationship with another person, the transcendence or divinity that is the basis of our spiritual existence. This third look comes when it is least expected, often in the vulnerability of a frustrating or challenging ethical situation. When we are open to it, it can provide insight, enrichment, and ethical guidance.
Ethical Responsibilities
Duties as a Physician
The AMA Code of Ethics is a document that has been revised over the years and includes opinions and statements on a variety of current issues. It incorporates the current version of the Code of Medical Ethics [American Medical Association, 2009]:
Additional guidance may be found in descriptions of the virtues needed for medical practice [Pellegrino and Thomasma, 1993]. These include the need for trustworthiness, compassion, empathy, prudent clinical judgment, altruism, fortitude, temperance, integrity, and primacy of the patient’s interest. Indeed, many of these virtues are implicit in the principles delineated by the AMA.
Many professional societies have developed ethical codes or guidelines that are specific for their field. The websites of the American Academy of Pediatrics (www.aap.org), the American Academy of Neurology (www.aan.com), and the Child Neurology Society (www.childneurologysociety.org) may be consulted for the most up-to-date statements about the ethical responsibilities of members of these societies. Legal issues involved in neurological professionalism were reviewed recently [Larriviere and Beresford, 2008], and the issues that define professional ethical responsibilities for neurologists were outlined by the past president of the American Academy of Neurology [Sergay, 2009].
Duties as a Pediatrician
Primary care involves the longitudinal management of all of the health issues of the child and family, and requires a commitment to being accessible, available, and capable. Effective primary care is compassionate, culturally competent, and comprehensive, and includes coordination and oversight of all of the child’s health problems [Tonniges and Palfrey, 2004]. Most child neurologists do not provide this type of primary care. Many do, however, provide many of the same elements of care for children whose neurologic problems constitute the main health issues. These include older children and adolescents who are otherwise healthy but have on-going neurologic problems, as well as patients with complex neurologic problems whose general health problems are fairly straightforward. Child neurologists have no obligation to take on this role and may confine their role to that of a consultant. Those who do take on this role would seem to have the same duties as those of a primary care physician, as listed above, except that their duties are limited to management of the child’s neurologic problems.
Because children are not capable of making sound judgments about their own best interests, others must judge for them what is in their best interests. Social convention and the law generally recognize that parents are the best judge of what is in the child’s best interest, but this recognition is not absolute. A substantial body of law and regulation governs when and in what circumstances a parent’s rights may be superseded. Consideration of these laws and regulations is beyond the scope of this chapter [see Beauchamp and Childress, 2001; Bernat, 2008]. Child neurologists may be called upon to give an opinion about what medical care is in the child’s best interest. They may also be asked about whether they believe the child is capable of independent judgment. Persons who are 18 years old are usually assumed to be fully autonomous adults who are capable of giving informed consent for medical treatment. Many neurologic patients with significant intellectual disabilities are not capable, however; therefore, others must be designated as guardians for them. The child neurologist should be aware of what is involved in determining the need for guardianship, and assist the patient and family in whatever way is appropriate.
The United Nations [1990] has formulated a declaration on the rights of children, the Convention on the Rights of the Child, which contains 54 Articles that stipulate the rights of the child to life, safety, health, education, and a decent standard of living. Article 23 states that a mentally or physically disabled child should enjoy a full and decent life in conditions that ensure dignity, promote self-reliance, and facilitate the child’s active participation in the community. It further recognizes the rights of the disabled child to special care. Article 24 states that the child should have access to quality health services, including primary care, preventive health care, and treatment of health conditions. Although the Convention’s declaration is not legally binding, it provides a strong moral statement about the internationally accepted obligations of states to protect the best interests of all children. Awareness of this international consensus may be helpful to physicians who are advocating for children under their care.
Duties as a Neurologist
Child neurologists are specialists or subspecialists and have duties that correspond to this role. They provide longitudinal care for children and adolescents with chronic neurologic disorders, and this includes corresponding duties that resemble those of primary care, as described previously. They also provide consultative opinions about diagnosis and treatment, both in outpatient and inpatient settings. As a consultant, the child neurologist has a duty to provide a fair, impartial, accurate, and (as much as possible) evidence-based statement about the facts of the case. The child neurologist’s principal role in evaluating ethical dilemmas is to clarify the facts. This is a critical role, because accurate data are essential for making sound ethical decisions [Coulter et al., 1988]. Indeed, poor or questionable ethical decisions often are due to inadequate specialized medical information regarding the diagnosis, treatment, and/or prognosis of a case. This problem is illustrated well in cases when the patient is in a vegetative state. Some may consider such a state permanent and hopeless after only a few weeks and seek to withdraw life-sustaining treatment. The child neurologist, acting as a consultant in such a case, would inform the family and caregivers about the published data indicating that the vegetative state is not considered permanent until 3 months after an anoxic injury and 12 months after a traumatic brain injury [Multi-Society Task Force on PVS, 1994]. The family may be given some hope for possible recovery of consciousness before these time periods, which may call for continued treatment and rehabilitation.
Research
Many child neurologists are involved in research, which carries additional ethical duties. One of the challenges for child neurologists involved in clinical research is to separate their ethical obligations as investigators from their ethical obligations as physicians responsible for treating patients who may be enrolled as subjects in the neurologist’s research study. This challenge is harder than it may seem. In the United States, research ethics is based on the Belmont Report [1979], which adopted the principles of autonomy, beneficence, and justice (see earlier discussion) as the basis of research ethics. In general, the researcher’s principal ethical obligation is to protect the rights and welfare of the research subject [Dunn and Chadwick, 2004]. Poorly designed research studies are inherently unethical because they are not likely to produce sound scientific results, and thus they place the patient-subject at risk for harm without the prospect of benefit. The researcher’s ethical obligation as an investigator to pursue well-designed scientific studies is secondary to his or her obligation to protect the subject involved in the research. When the research subject is also a patient, this means that the child neurologist-investigator’s clinical duties to the patient are ordinarily stronger than his or her duties to enroll subjects in the research study.
In the United States, federally sponsored research is governed by the Code of Federal Regulations, which stipulates the roles and responsibilities of researchers and institutions involved in clinical research [see Dunn and Chadwick, 2004]. Researchers are required to obtain review and approval of the research study by a properly constituted Institutional Review Board for the Protection of Human Subjects in Research (IRB). Child neurologists involved in clinical research have legal and ethical obligations to follow these rules and regulations. In general, ethical issues in research should be considered when the study is being designed, not just at the end of the process when IRB review and approval are requested. The researcher should be knowledgeable about ethical issues in research. If the researcher has questions about ethical aspects of study design or protocol development, most IRBs will provide assistance. Building ethics into the study from the beginning will usually prevent problems later during the process of IRB approval, as well as during continuing review and oversight of the study.
Ethical Problems
Personhood
Critical ethical problems in child neurology often center on the question of personhood. Some authorities [Field and Behrman, 2004] consider this the most important problem in bioethics. Indeed, the history of the concept of personhood can be traced to Plato and Aristotle [Mahowald, 1995]. This history includes many rich and varied discussions based on several key questions. Should all human beings be considered persons, in a moral sense, to whom ethical duties are owed? Or are some human beings (such as fetuses or infants with anencephaly) “nonpersons” who can be treated differently than “real persons”? Is personhood absolute or are there degrees of personhood, and thus degrees of ethical obligations? Can personhood be lost while human existence persists – for example, in a vegetative state? Are there reliable and valid criteria that one can use to determine whether a human being is a person?
The capacity for rational thought is often considered to be what separates human persons from nonpersons, yet rationality may not be sufficient by itself. Plato, Aristotle, Augustine, Aquinas, and other classical philosophers emphasized the unity of reason and spirit, or soul [Mahowald, 1995]. Current religious and theological arguments maintain this position by arguing that all human beings have a God-given soul, which confers moral personhood and that requires ethical respect. Berrigan wrote that the presence of God is most apparent when we are with those who are unable to respond to us [Berrigan, 2000]. These arguments are unconvincing to those who do not share the underlying religious premise, however.
Enlightenment philosophers, such as Locke and Kant, redefined the issue to emphasize self-consciousness, or the rational ability to have a concept of oneself as a unique being and thus to exercise autonomy or free will. This definition would suggest that human beings who do not have this ability may not be fully human persons in a moral sense. Modern thinkers have sought to identify criteria by which one may determine whether personhood is present. Fletcher [1979] identified a number of such criteria, including self-awareness, self-control, a sense of one’s history and future, the capacity to relate to others, and the ability to communicate. For Fletcher, IQ could be used as a surrogate measure of these abilities, so that an IQ below 20 meant that one was not a person. Utilitarian theory has been used to arrive at essentially the same position [Kuhse and Singer, 1985]. This position has been criticized on philosophical grounds [Byrne, 2000]. Hauerwas considered the question of developing criteria for personhood “fundamentally wrong-headed” because it ignores the real question, which is how others should relate to those who may not meet these criteria: “I suspect that we are human exactly to the extent we can reach out and provide care to those who have no right to it” [Swinton, 2004].
The question of what it means to be human can be considered from an anthropologic and historical perspective. Fernandez-Armesto [2004] identified six challenges to our understanding of human personhood:
Considering these challenges, he concluded that the boundaries of what we consider “humankind” or human personhood, from an anthropologic perspective, are by definition necessarily indistinct [Fernandez-Armesto, 2004].
What does this mean for child neurologists? Many patients (such as infants with severe neurologic disabilities, children with profound intellectual disability, and adolescents in a persistent vegetative state) would not meet the criteria of personhood advocated by Fletcher. Are physicians’ ethical obligations to them any less than to other patients who are more obviously human persons, or do theories of justice require physicians to provide more compensatory resources to help them function more effectively in society [Veatch, 1986]? Theories of beneficence argue that physicians should attempt to promote and protect the patient’s quality of life as perceived by the patient, regardless of what physicians may think of it [Beauchamp and Childress, 2001]. From a clinical perspective, parents rarely regard their children with severe disabilities as nonpersons. Child neurologists, working together with parents and other caregivers, will want to focus on doing what is best for the child and family. Distinguishing between moral status and moral agency [Mahowald, 1995], physicians may conclude that patients whose moral status is questionable because of presumably limited personhood are still moral agents with human rights to whom those with greater moral status have ethical obligations as members of human society.
Euthanasia
The challenge of euthanasia is one of the most important ethical issues in neurology and medicine today. Conventional thinking distinguishes between passive euthanasia (not doing something to preserve life) and active euthanasia (doing something to end life). Passive euthanasia is generally considered acceptable medical practice in some situations, whereas active euthanasia is not (and is illegal in most situations). However, this distinction may be vague and confusing in some cases. Legitimate and illegitimate applications of both passive and active euthanasia can be identified. In their discussion of the ethical principle of nonmaleficence, Beauchamp and Childress [2001] argue for recasting the distinction in terms of respect for autonomy and serving the patient’s best interests. They argue that, in some carefully specified situations, physicians may legitimately assist patients in dying (active euthanasia) if the action responds to the patients’ wishes and serves their interests.
Passive euthanasia (withdrawal of life-sustaining treatment) is often considered for persons who are in a persistent vegetative state (PVS). Consensus exists regarding the medical aspects of a vegetative state in children and adults [Multi-Society Task Force on PVS, 1994], but the ethical and legal issues are more contentious [Jennett, 2002]. With respect to children and adolescents, two questions arise:
The Multi-Society Task Force on PVS included representation from the Child Neurology Society and reviewed the literature to address these questions. The Task Force concluded that the concept of the vegetative state cannot be applied to preterm infants, and the diagnosis of a vegetative state is difficult to make before 3 months of life. An exception to this statement may be made for infants with true anencephaly who, by definition, are in a vegetative state. Caregivers are often confused when patients demonstrate subtle or minimal signs of responsiveness, which would suggest that the diagnosis of PVS is no longer accurate. Patients who demonstrate minimal but definite behavioral evidence of self or environmental awareness may be diagnosed instead as being in a minimally conscious state, which is distinct from the vegetative state. Diagnostic criteria exist for distinguishing between a minimally conscious state and a vegetative state in children [Ashwal and Cranford, 2002]. Data also exist regarding the prognosis for children and adolescents in a minimally conscious state or a vegetative state. It is possible to distinguish between a mobile (ability to lift the head, roll over, or sit) and an immobile minimally conscious state, but studies have found little difference in survival between children in either state [Strauss et al., 2000]. For children 3 years of age in a vegetative state or an immobile minimally conscious state, 12–18 percent had evolved to a state better than a minimally conscious state after 3 additional years. For children in a vegetative state from birth to 1 year of age, median survival was 4.2 years and life expectancy was 7.2 additional years. For adolescents still in a vegetative state 1 year after onset, median survival was 5.2 years and life expectancy was 10.5 additional years [Strauss et al., 1999]. Unpublished clinical experience suggests that these survival estimates are probably too conservative, since currently available medical and nursing care may permit much longer survival in some cases.
Withdrawal of life-sustaining treatment (including nutrition and hydration) is generally considered legally and ethically appropriate for children and adults who are in PVS [Jennett, 2002], although others disagree. For example, Pope John Paul [2004] argued that the withdrawal of assisted (artificial) nutrition and hydration “has to be considered a genuine act of euthanasia by omission, which is morally unacceptable.” For Roman Catholics, this is an important opinion that should be considered carefully in the on-going debate about the care of patients in a vegetative state [Shannon and Walter, 2004]. The legal and ethical standards for withdrawing life-sustaining treatment from patients in a minimally conscious state are much less clear, since such patients theoretically could feel pain and suffering [Ashwal and Cranford, 2002].
The concept of futility implies that a proposed treatment or course of action offers negligible potential for overall patient benefit, whether that potential is considered quantitatively in terms of the probability of success or qualitatively in terms of the expected impact on the patient’s quality of life. The question often arises when patients or families request treatment that caregivers do not believe is appropriate. Rather than focus on strict guidelines or policies to follow in such cases, physicians are encouraged to develop fair and transparent procedures for decision-making that encompass the views of all parties involved in these difficult situations [Shevell, 2002].
Voluntary active euthanasia is much more controversial than passive euthanasia [Smith, 1997]. Often called mercy killing or physician-assisted suicide, it is opposed by the American Medical Association and is illegal in all of the United States, except in Oregon. On the other hand, it is legal in some countries, most visibly in the Netherlands, where it has been extended to include children younger than 12 years of age. Following Beauchamp and Childress [2001], many people wish to be able to exercise their autonomy rights and to choose death (with or without medical assistance) when this is a conscious, carefully considered, noncoerced, personal decision they make for themselves. Whether it is ever ethical for others to make this decision on behalf of nonautonomous persons (such as children and adolescents) is not at all clear (even in the Netherlands), and no convincing ethical argument has been advanced so far to support a consensus on this point.
Organ Donation
The question of whether or not to withdraw life support takes on a special urgency when the possibility of organ donation is present. Organ donation is often considered after a diagnosis of brain death has been made, but the number of organs available in this context is limited. Efforts to increase the number of organs available for donation has recently focused on developing policies and procedures to be followed in cases of cardiac death. This is called “donation after cardiac death,” or DCD. Patients become candidates for DCD if they are on life-sustaining treatment (such as a ventilator) and a decision has already been made to withdraw the life-sustaining treatment. Patients in PVS who are not on a ventilator are not candidates for DCD, since withdrawal of nutrition and hydration leads to death too slowly for organs to be recovered. When the family consents to DCD for a patient who is a good candidate, the patient is taken to the operating room, where life support is withdrawn and the medical team waits for the patient’s heart to stop beating. After a reasonable interval has passed to be certain that cardiac arrest is irreversible (generally a few minutes), cardiac death is declared and surgery for organ procurement begins [Steinbrook, 2007]. Current DCD policies do not evaluate the decision to withdraw life support, however. For example, a DCD procedure could be implemented if parents requested that life support be withdrawn from a child who is in a vegetative state 1 month after a traumatic brain injury, even though the child might have recovered consciousness and had an acceptable quality of life if life support had been maintained [Coulter, 2010]. Current DCD policies do not consider whether the decision to withdraw life support is ethical, since DCD procedures begin only after this decision has already been made. Thus, a key ethical issue in DCD would seem to consist of careful scrutiny of the decision to withdraw life support prior to DCD. This scrutiny provides a key role for the child neurologist in clarifying the diagnosis and prognosis.
Perfection and Neuroethics
The attempt to create more perfect children is universal and perhaps understandable. Parents do not wish to create a child whom they believe to be imperfect [Murray, 1996]. Some deaf parents may wish to create a child whom others might consider imperfect because of deafness but whom they consider more perfect because of the child’s ability to participate in deaf society [Middleton et al., 2001]. Even parents who love and accept their child’s imperfections would likely still prefer to have those imperfections disappear if possible. In asking whether “the retarded suffer from being retarded,” Hauerwas [1986] argues that individuals project on them their own fears of what it would be like to have an intellectual disability and thus fail to imagine what living with such a disability is really like. Obversely, people desire perfection for their children because they value perfection in themselves.
The desire for perfection may be a relevant consideration when parents must make decisions about life-sustaining treatment for infants and young children faced with the prospect of lifelong severe disability. Often, the child is still dependent on life-sustaining technology, the withdrawal of which will result in the child’s death. The prognosis may be somewhat uncertain and likely to become clearer with time [Coulter, 1987]. Yet if the parents wait, the child’s medical situation may stabilize and no longer require life-sustaining technology. Parents who are relatively intolerant of imperfection (lifelong severe disability) may thus choose to withdraw life-sustaining treatment before the exact prognosis is clarified, rather than wait and lose the opportunity to choose. Another factor that may influence the decision to withdraw life-sustaining treatment is the opportunity it provides for DCD, which some parents may consider a better outcome than survival with lifelong severe disability. This situation is very difficult for the child neurologist caring for the patient, whose principal duties are to provide accurate data about diagnosis and prognosis and to support the family’s decision [Glass, 2002]. Although some observers think that parents may be making these choices earlier and withdrawing support more often than they did in the past, little or no published data are available to verify this observation or to explore why this might be true. Literature on the social and spiritual significance of disability [Eiesland, 1994; Vehmas, 2004] points out that individuals with disabilities often perceive their quality of life to be better than those without disabilities might expect. On the other hand, some contemporary philosophers argue that personhood is limited in the presence of severe disability, and withdrawal of life support is appropriate [Kuhse and Singer, 1985]. Perhaps child neurologists can do no more than be aware of these issues and discuss them with families who are faced with these difficult choices.
The issue of perfection is framed more starkly when considering what has been termed cosmetic neurology [Dees, 2004]. Chatterjee [2004] distinguished between the goal of medicine to treat disease and the goal to enhance quality of life by improving normal functions. Should drugs be prescribed to enhance strength, coordination, attention, learning, memory, mood, and affect in those who are neurologically normal? He identified four ethical dilemmas related to cosmetic neurology:
Another aspect of cosmetic neurology considers whether and to what extent parents should be able to modify their children who have significant neurological disabilities. What are the ethical boundaries of such treatment? Suppose a drug were available that might inprove cognitive function in a child with intellectual disability, but which also had significant potential adverse effects, including death. (Indeed, drugs of this type are being studied.) Should parents be able to choose this treatment for their child? Suppose a treatment were available that would attenuate the growth of a child with severe disability, so that the child would remain small and immature and the family would be able to continue to care for the child at home [Gunther and Diekema, 2006; Diekema and Fost, 2010]. Should parents be able to choose this treatment for their child, even if the treatment is irreversible and the expected outcome is unproven? These are difficult questions and no general consensus exists regarding how to answer them. At this point, it is probably best to consider them in a research context and apply the ethical guidelines that are appropriate for conducting clinical research [Dunn and Chadwick, 2004].
Cosmetic neurology is one aspect of what has been termed neuroethics. This concept incorporates the application of modern neuroscientific research to clinical problems and to general society. Related to this, the term neurotheology has been coined to encompass the application of neuroscientific research to understanding religious and spiritual experience [Joseph, 2002]. Functional neuroimaging now allows us to evaluate personal information such as personality traits, social and moral attitudes, individual preferences, deception, guilt, and thoughts [Farah and Wolpe, 2004]. The principal ethical challenges of these applications of neuroimaging relate to privacy, autonomy, and respect for the person.
Another aspect of neuroethics is the use of new genetic knowledge to diagnose and treat neurogenetic disorders. Ethical issues in genetic diagnosis include stigma and privacy, whereas gene therapy raises ethical issues similar to those of cosmetic neurology [Avard and Knoppers, 2002]. Scientific progress is inevitable and desirable, and the challenges of neuroethics will become even more important in the near future. All neurologists must be aware of these ethical challenges and become informed about appropriate responses as they are developed.
Synthesis
The child neurologist also listens to the external voices of others who are involved in the clinical situation. Foremost among them is the voice of the family. When love is present, families usually find a way to deal with whatever life hands them. It may not be the “right” way (the way others want them to take), but it is a way that works for them and deserves respect. At any given point in time, most people are doing the best they can, given their skills and abilities and the pressures and limitations they face. When physicians seek to understand the situation from the family’s point of view, they may be able to help them do the best they can for themselves and for their child [Coulter, 2002]. The neurologist will also hear the voices of other patients and families he or she has treated and followed over the years, who were in a similar situation in the past and whose subsequent history speaks to the wisdom of decisions that were made [Freeman, 2004].
“One lesson I believe I have learned is that decision-making should be a process, and the process for arriving at a decision is far more important than the decision arrived at. This process cannot be left solely to the family, or to relatives and friends, with their biases and prejudices, any more than it can be left solely to the physician. Physicians and families together must learn to work out a plan for the handicapped or potentially handicapped newborn – and likewise for the premature infant, for the person with late-stage Alzheimer’s disease, for the critically ill patient, and for individuals at both ends of life” [Freeman, 2004].
