Dementia affects millions of people throughout the world. Thinking through Dementia offers a critique of the main models used to understand dementia-the biomedical, neuropsychological, and social constructionist. It discusses clinical issues and cases, together with philosophical work that might help us to better understand and treat this illness.

In lieu of an abstract, here is a brief excerpt of the content:Introduction:The Heat of Mild Cognitive ImpairmentJulian C. Hughes (bio)Keywordsaging, explanation, mild cognitive impairment, understanding, valuesDebates about mild cognitive impairment (MCI) are generating heat, albeit civilized heat. But under the surface, as I think the papers in this special issue demonstrate, the civilized heat comes from a good deal of passion. One way in which philosophy can contribute to the debate is by making plain the sources of this (...) passion, so that the motivating forces are clearer.One motivating force is this: There will be people who do not have dementia but who have symptoms or signs that might predict dementia, which cause them concern, whom we might help by early intervention. The intervention might involve advice and support, or it might involve some form of drug treatment; and in the utopia of our dreams, it might involve prevention. All of this is very motivating for clinical scientists. It also offers a laudable motivation to pharmaceutical companies, who simultaneously must have regard to the possibility of profits for their shareholders.Here, however, is an alternative motivation: The effects of aging must not be ignored if help can be given, but older people must not be stigmatized by a medical process that thrusts disabling labels on them. People age, but they age differently, and it is better to recognize difference, both from a biological and from a philosophical perspective. Thus, a passionate commitment to the cause of individual agency in old age and a desire for authentic autonomy for older people provide strong motivation too.At root, then, the conflicting passions over MCI reflect the age-old struggle in the philosophy of psychiatry between the natural sciences (Naturwissenschaften) and the human or cultural sciences (Geisteswissenschaften): the tension is between a tendency to approach the problem with the aim of eliciting a scientific explanation and a tendency to try to achieve a human and cultural understanding of the phenomena (Phillips 2004). So, although MCI can be regarded as an explanatory diagnostic entity with some predictive value, it can also be regarded as a label that might cause harm or as a human phenomenon that requires understanding. Furthermore, MCI raises ontological questions about the nature of disease entities. And there is a wider issue as well about how aging itself should be regarded.From a biological perspective, it turns out there is no clear cutoff between what is normal and what [End Page 1] is not. Hence, in a number of ways, values seem to be as important as facts (Sadler 2005). Perhaps philosophy should content itself with saying no more than this: MCI ought not to be considered or debated as if it lies outside the realm of evaluative judgment. The very possibility of its existence as a clinical entity is a matter worthy of moral and social discourse.The direction of thought indicated here and in the papers that follow, however, is more radical than the easily won point that the "diagnosis" of MCI is not value free. On the back of the biological point, that there is a continuum between physiological and pathological aging, is the broader philosophical point that aging can neither be understood solely in terms of physiology nor in terms of pathology, nor even in terms of both. Ageing represents, inter alia, a social and cultural phenomenon manifest in the context of particular psychological and spiritual responses to a mixture of physiological adaptations and pathological predispositions. Without the broader picture, we tend to characterize old age, as Michael Bavidge has suggested elsewhere, in terms of deteriorations: "We should think of old age as offering alternative rather than impaired ways of experiencing life" (2006, 49). The difficulty is that any diagnosis seems to suggest impairment in one form or another. The radical suggestion, therefore, might be to commend descriptions that encourage shared understanding over and above the giving of names and labels.In a brief critique of the scientific approach to "banal memory disorders and MCI", Jean-Marie Léger, like Bavidge, regrets the extent to which people with cognitive impairment "are described in terms of what they have lost, with no regard for the wealth of faculties which are still present." Léger... (shrink)

Dementia is an illness that raises important questions about our own attitudes to illness and aging. It also raises very important issues beyond the bounds of dementia to do with how we think of ourselves as people--fundamental questions about personal identity. Is the person with dementia the same person he or she was before? Is the individual with dementia a person at all? In a striking way, dementia seems to threaten the very existence of the self.LThis book brings together philosophers (...) and practitioners to explore the conceptual issues that arise in connection with this increasingly common illness. Drawing on a variety of philosophers such as Descartes, Lock, Hume, Wittgenstein, the authors explore the nature of personal identity in dementia. They also show how the lives and selfhood of people with dementia can be enhanced by attention to their psychological and spiritual environment. Throughout, the book conveys a strong ethical message, arguing in favor of treating people with dementia with all the dignity they deserve as human beings. The book covers a range of topics, stretching from talk of basic biology to talk of a spiritual understanding of people with dementia. Accessibly written by leading figures in psychiatry and philosophy, the book presents a unique and long overdue examination of an illness that features in so many of our lives. (shrink)

Dementia is dead, long live aging! This chapter sets out the philosophical sources for understanding working with "dementia." The concept, "dementia," serves no useful purpose. Even "Alzheimer's disease" turns out to be problematic. This is because there is a lack of precision around the boundaries of these notions. The messiness that surrounds these notions, in terms of facts and values, is made obvious when we consider mild cognitive impairment, which is said to be a pre-dementia state. It makes more biological (...) sense to think in terms of the ageing brain, rather than to search for discrete disease entities. We need to think in terms of dementia-in-the-world. Ageing is not something that we do solely at the end of our lives: it is a part of our lives, to be celebrated. We must look more broadly at dementia-in-the-world as a feature of our ageing lives.

With more people in the world living into older age, Alzheimer's and other Dementias: The Facts takes a comprehensive look at the spread of dementia, and provides authoritative information and practical advice for sufferers, their families, and the medical professionals who care for them. -/- Written by a consultant in old age psychiatry, the book provides an overview of all the different types of dementia (including younger-onset dementias), from the most-recognized - Alzheimer's - to the less-frequent types, such as those (...) caused by inherited metabolic disorders or HIV. The book guides the reader step-by-step through how the brain works, and explains in clear and simple language the effect of dementias on the brain, and the impact on an individual's cognitive function. -/- A dedicated chapter explains how a diagnosis is reached, including the different modes of assessment, from blood tests carried out by a GP, to specialist scans, highlighting how the brain actually works. Detailed sections cover the latest treatments available, including the controversial use of antipsychotic medication, and the possibility of disease-modifying treatments in the future. -/- The book also explains how the multi-disciplinary team works together to look after the sufferer's social needs, such as bathing and washing, as well as their spiritual and palliative needs. Alzheimer's and other Dementias: The Facts provides all the relevant information and guidance for sufferers, family and their care-givers to choose the right intervention at the right time, to create - as the book advocates - a unique and personalized management plan.

It might seem too obvious to start with this quotation:O day and night, but this is wondrous strange!And therefore as a stranger give it welcome.There are more things in heaven and earth, Horatio,Than are dreamt of in your philosophy.But then, I think it is obviously correct, as Professor Waterman suggests, that "There are more things in heaven and earth" than simply the application of the scientific method to medical practice. Perhaps there are two quick comments to make about the quotation. (...) First, in Shakespeare's time, "philosophy" would have included science; second, Shakespeare apparently contemplated using "our" rather than "your." So Hamlet is speaking to us, not just to Horatio, and he's speaking about our... (shrink)

This paper introduces the notion of patterns of practice and shows the extent to which it is useful at the level of practice and at a profound philosophical level. The notion makes deep connections with ideas in the realm of the philosophy of language and thought and, in addition, it connects to virtue ethics. Using the example of whether or not to admit someone using compulsory powers or whether to treat them in the community, the notion of patterns of practice (...) can be used to demonstrate the internal and external coherence of decisions in psychiatric care and thus to offer clinical and ethical justification.

Este artículo discute los problemas relacionados con la toma de decisiones en la demencia (y otras deficiencias cognitivas progresivas). Presenta cinco de estos temas; a saber, los relacionados con el lugar de residencia, la atención forzada, la medicación encubierta (en relación con la cual también mencionaré la verdad), la sexualidad, la comida y la bebida, que incluye cierta consideración de suspender y retirar el tratamiento en general. Después reflexionará sobre cómo se trata la toma de decisiones en la práctica clínica; (...) posteriormente discutirá algunos temas con-ceptuales: capacidad (o competencia), mejores intereses y toma de decisiones con apoyo. Terminará con algunos comentarios sobre la importancia de la individualidad en relación con los problemas éticos que rodean la toma de decisiones en la demencia. (shrink)

Highly reputable bodies have said that lying is to be avoided when speaking with people living with dementia, unless it cannot be. And yet, the evidence is that many professionals looking after people who live with dementia have been lying to them. I wish to consider an underlying philosophical justification for the moral position that allows lying under some circumstances whilst still condemning it generally. It can seem difficult to ignore the immorality of lying, but thinkers have developed arguments to (...) get around the absolute prohibition. I shall argue that in concrete circumstances the object and the intended end of an action are not as clearly distinct as has been presumed. Further, looking at how language functions allows us to appeal to speech acts and to see the illocutionary force of a statement as way to broaden its purview. We need not think that the only options are between lying and not lying; there is also the possibility, in exigent circumstances, of ‘conforming to the reality’, which would allow a more nuanced account of moral acts, where the intentional nature of the act is no longer to lie. There are, thus, extreme concrete circumstances where not to speak the truth may be excusable, even if regrettable. (shrink)

How are we to understand dementia? The main argument involves an analysis (in Chapter 2) of intentional mental states, using Wittgenstein's discussion of rule-following, which suggests that such states demonstrate an irreducible, transcendental normativity. This externalist account of intentional mental states highlights the worldly embedding of practices. In Chapters 3,4 and 5, this analysis is applied respectively to the disease, cognitive neuropsychology and social constructionist models of dementia. Whilst clinically and scientifically useful, none generates an adequate account of normativity. The (...) Wittgensteinian analysis supplies a constitutive (as opposed to causal) account that supports the notion of dementia-in-the-world (Chapter 6). A full understanding of dementia requires the human-person-perspective in order to accommodate all that dementia amounts to in the normatively-constrained world. The sub-plot considers our understanding of the person. Rather than the Locke-Parfit view, which stresses psychological continuity, the Wittgensteinian analysis supports the situated-embodied-agent view of the person (Chapters I and 6). This view and the notion of the human-person-perspective are mutually supportive, so that main and subplot both encourage a broader understanding. The works of Wittgenstein have acted as a primary source, with secondary literature commenting on his works. In discussing the models of dementia, I have cited primary sources. I have also considered philosophical works pertinent to the particular models, usually in connection with the mind-brain problem. The thesis concludes that there is no single way to understand dementia, but any understanding will be from the human-person-perspective, in accord with the situated-embodied-agent view and reflecting an externalist construal of intentional psychological states. This has implications for further research in philosophy, medical ethics and gerontology. The unique application of the Wittgensteinian philosophical analysis to clinical reality suggests an approach to people with dementia that stresses personhood in the context of embedded, embodied histories and continuing relationships with others.

Background For a variety of sociological reasons, different types of centredness have become important in health and social care. In trying to characterize one type of centredness, we were led to consider, at a conceptual level, the importance of the notion of centredness in general and the reasons for there being different types of centeredness. Method We searched the literature for papers on client-, family-, patient-, person- and relationship- centred care. We identified reviews or papers that defined or discussed the (...) notions at a conceptual level. The reviews and papers were analyzed as text transcripts. Results We identified 10 themes that were common to all the types of centredness. At a conceptual level we could not identify thematic differences between the types of centredness. These findings were subjected to a philosophical critique using ideas derived from Wittgenstein. Conclusion Different types of centredness are required in different contexts. The differences are justified by their practical utility. The unifying themes of centredness, however, reflect a movement in favour of increasing the social, psychological, cultural and ethical sensitivity of our human encounters. (shrink)

BackgroundConcerns about decision making related to resuscitation have led to two important challenges in the courts resulting in new legal precedents for decision-making practice. Systematic research investigating the experiences of doctors involved in decisions about resuscitation in light of the recent changes in law remains lacking.AimTo analyse the practice of resuscitation decision making on hospital wards from the perspectives of doctors.DesignThe data presented in this paper were collected as part of a wider research study of end-of-life care in an acute (...) hospital setting. Data collection comprised ethnographic non-participant observation on two acute hospital wards and individual interviews with patients, relatives and healthcare professionals caring for patients thought to be approaching the end of life. Data were analysed using a constructivist grounded theory approach.ResultsDiscussions and decision making about resuscitation present many challenges for those involved on acute medical wards. The data highlight the potential for multiple interpretations of legal precedents, creating misunderstandings that may impact patient care in less positive ways.ConclusionsThis paper provides unique insights into how doctors respond to the changing medico-legal culture and the subsequent effects on patient care. It demonstrates how the juridification of medical practice can occur. It highlights the potential benefit of a structure to support clinicians, patients and relatives in discussing and navigating decisions around care at the end of life in line with the patient’s wishes and preferences. Recommendations for future research are made and legal ramifications are discussed. (shrink)

We reflect, using a vignette, on conceptual tensions and the value judgements that lie behind difficult decisions about whether or not the older person with dementia should return home or move into long-term care following hospital admission. The paper seeks, first, to expose some of the difficulties arising from the assessment of residence capacity, particularly around the nature of evaluative judgements and conceptual tensions inherent in the legal approach to capacity. Secondly, we consider the assessment of best interests around place (...) of residence, which demonstrates significant conceptual tensions. In addition, ‘best interests’ raise issues around the perception of risk and the perceptions of the family and crucially involve the notions of autonomy and trust. Finally, we not only gesture at some practical considerations based on insights from values-based medicine, but also make the suggestion that we require tighter functional assessments of residence capacity coupled with broader judgements about best interests.

BackgroundDecision-making in end-stage dementia is a complex process involving medical, social, legal and ethical issues. In ESD, the person suffers from severe cognitive problems leading to a loss of capacity to decide matters regarding health and end-of-life issues. The decisional responsibility is usually passed to clinicians and relatives who can face significant difficulty in making moral decisions, particularly in the presence of life-threatening swallowing problems.AimThis study aimed to understand the decision-making processes of clinical teams and relatives in addressing life-threatening swallowing (...) difficulties in ESD in long-term care in Malta.MethodThe study followed a qualitative approach where six case studies, involving six different teams and relatives of six different patients, were interviewed retrospectively to understand their decision-making in connection with the management of swallowing difficulties in ESD. Data were collected through semistructured interviews with each stakeholder. All data were transcribed and subjected to thematic analysis.ResultsFour themes were identified: the vulnerability of patients in dementia decision-making; the difficult role of relatives in decision-making; the decisional conflict between aggressive care through tube feeding versus oral comfort feeding; a consensus-building decision-making process as ideal to facilitate agreement and respect for patient’s dignity.ConclusionDecision-making to manage swallowing difficulties in ESD is a challenging process, which involves an interpretation of personal values, beliefs, patient preferences, care needs and clinical practice. Better communication between clinicians and relatives in dementia helps promote agreement between stakeholders leading to a care plan that respects the dignity of patients at their end of life.

I contend that mathematical domains are freestanding institutional entities that, at least typically, are introduced to serve representational functions. In this paper, I outline an account of institutional reality and a supporting metaontological perspective that clarify the content of this thesis. I also argue that a philosophy of mathematics that has this thesis as its central tenet can account for the objectivity, necessity, and atemporality of mathematics.

Stereotypes of social construction suggest that the existence of social constructs is accidental and that such constructs have arbitrary and subjective features. In this paper, I explore a conception of social construction according to which it consists in the collective imposition of function onto reality and show that, according to this conception, these stereotypes are incorrect. In particular, I argue that the collective imposition of function onto reality is typically non-accidental and that the products of such imposition frequently have non-arbitrary (...) and objective features. These conclusions are interesting in and of themselves since they debunk important aspects of our socially constructed conception of social construction. Yet, additionally, they have important implications for the viability of mathematical social constructivism since resistance to such constructivism is frequently grounded in the observation that mathematics is non-accidental, non-arbitrary, and objective. As a secondary focus, I explore these implications in this paper. (shrink)

In 2011 the English Court of Protection ruled that it would be unlawful to withdraw artificial nutrition and hydration from a woman, M, who had been in a minimally conscious state for 8 years. It was reported as the first English legal case concerning withdrawal of artificial nutrition and hydration from a patient in a minimally conscious state who was otherwise stable. In the absence of a valid and applicable advance decision refusing treatment, of other life-limiting pathology or excessively burdensome (...) suffering, the judgement makes it clear that the obligation on health professionals falls strongly in favour of preserving life. Although the Court sought to limit the judgement as closely as possible to the facts of the case, it is likely to have a significant impact on life-sustaining treatment decisions for people in states of low awareness. This paper outlines the main legal features of the judgement. (shrink)

The recent judgement in the case of Re:M in which the Court held that it would be unlawful to withdraw artificial nutrition and hydration from a woman in a minimally conscious state raises a number of ethical issues of wide application. Central to these is the extent to which precedent autonomous decisions should be respected in the absence of a legally binding advance decision. Well-being interests can survive the loss of many of the psychological faculties that support personhood. A decision (...) to respect precedent autonomy can contradict the well-being interests of the individual after capacity is lost. These decisions raise difficult questions about personal identity and about the threshold of evidence that is required of an earlier decision in order for it to be respected. (shrink)

In this article, I articulate and defend an account of corporations motivated by John Searle’s discussion of them in his Making the Social World. According to this account, corporations are abstract entities that are the products of status function Declarations. They are also connected with, though not reducible to, various people and certain of the power relations among them. Moreover, these connections are responsible for corporations having features that stereotypical abstract entities lack (e.g., the abilities to take actions and make (...) profits). (shrink)

At the University of Pretoria the author, a practical theologian, experiences a fruitful soil for the development of an interdisciplinary process. He referred to concrete examples of cooperation, but used the article to reflect on best practices for the interdisciplinary dialogue. He came to the conclusion that it probably made more sense to talk of Practical-theological alternatives rather than to describe the subject in a single fixed manner of understanding and action. Our goal should rather be to open up the (...) boundaries between Practical Theology, Human, Social and Natural Sciences. (shrink)

I discuss social constructivism in the philosophy of mathematics and argue for a novel variety of social constructivism that I call Practice-Dependent Realism.

I discuss a puzzle that shows there is a need to develop a new metaphysical interpretation of mathematical theories, because all well-known interpretations conflict with important aspects of mathematical activities. The new interpretation, I argue, must authenticate the ontological commitments of mathematical theories without curtailing mathematicians' freedom and authority to creatively introduce mathematical ontology during mathematical problem-solving. Further, I argue that these two constraints are best met by a metaphysical interpretation of mathematics that takes mathematical entities to be constitutively constructed (...) by human activity in a manner similar to the constitutive construction of the US Supreme Court by certain legal and political activities. Finally, I outline some of the philosophical merits of metaphysical interpretations of mathematical theories of this type. (shrink)

Two topics figure prominently in recent discussions of mathematical structuralism: challenges to the purported metaphysical insight provided by sui generis structuralism and the significance of category theory for understanding and articulating mathematical structuralism. This article presents an overview of central themes related to these topics.

Ullin Place's contributions to the literature of behaviour analysis and behaviourism span the period from 1954 to 1999. In appreciation of his scholarship and breadth of vision, this paper reviews an early widely-cited contribution ("Is consciousness a brain process?" British Journal of Psychology, 1956, pp. 47-53) and a late one which should become widely cited ("Rescuing the science of human behavior from the ashes of socialism," Psychological Record, 1997, pp. 649-659). It is noted that the sweep of Place's work links (...) behaviour analysis to its philosophical roots in the work of Ryle and Wittgenstein and also looks forward to the further functional analysis of language-using behaviour.

This psychology textbook offers a comprehensive examination of the basic principles of behavior analysis and their application to issues of social significance. Behavioral scientists are interested in elucidating the fundamental principles that govern the behavior of human and non-human animals. Behavior Analysis is designed to meet the needs of senior undergraduate courses and postgraduate training in behavior analysis and its applications. The eleven comprehensive chapters: ·consider how fundamental principles of behavior can be used in an applied setting to identify behavior (...) to be changed, to select treatments which increase of decrease behavior, and to evaluate the effectiveness of interventions; and ·give examples from various disciplines, including dietetics, education, occupational therapy, and speech therapy, as well as clinical, social, health and community psychology. In addition to covering core material essential for courses in psychology, this volume will also provide a useful account of behavioural psychology and its applied uses for students and professionals from a wide range of fields.

Although conditioned suppression has face validity as a technique for assessing resistance to change of operant behaviour, it is not discussed by Nevin & Grace. However, application of their approach to the results of a conditioned suppression study that varied food deprivation and reinforcement magnitude produces paradoxical results.

Different sciences approach the brain-behaviour system at various levels, but often apparently share terminology. “Function” is used both ontogenetically and phylogenetically. Within the ontogeny it has various meanings; the one adopted by Arbib et al. is that of mainstream cognitive psychology. This usage is relatively imprecise, and the psychologists who are sceptical about the ability of cognitive psychology to predict behavioural outcomes may have the same reservations about Arbib et al.'s cognitive neuroscience.

Rose provides a coherent account of how a number of simplifying assumptions apparently come together to support neurogenetic determinism, or “ultra-Darwinism.” This view, he demonstrates, is deeply flawed. He proposes instead that we must take account of the interaction of processes that determine our developmental trajectory at every stage. Unfortunately, he associates this defensible position with the claim that this gives freedom of action to humans. The implications of this for the interpretation of his general thesis are discussed.

The generic account of selection proposed by Hull et al. readily fits operant learning where, by comparison with natural selection, the process is well understood but little is known about the mechanism. Objections within psychology, that operant learning ignores internal processes, fail to recognise the general significance of behaviour-environment interactions. Variation within operant response classes requires further investigation.

Achievement test differences between boys and girls and between young men and young women, mostly favoring males, extend far beyond mathematics. Such pervasive differences, illustrated here, may require an explanatory theory broader than Geary's.
