As it emerged from philosophical analyses and cognitive research, most concepts exhibit typicality effects, and resist to the efforts of defining them in terms of necessary and sufficient conditions. This holds also in the case of many medical concepts. This is a problem for the design of computer science ontologies, since knowledge representation formalisms commonly adopted in this field (such as, in the first place, the Web Ontology Language - OWL) do not allow for the representation of concepts in terms (...) of typical traits. The need of representing concepts in terms of typical traits concerns almost every domain of real world knowledge, including medical domains. In particular, in this article we take into account the domain of mental disorders, starting from the DSM-5 descriptions of some specific disorders. We favour a hybrid approach to concept representation, in which ontology oriented formalisms are combined to a geometric representation of knowledge based on conceptual space. As a preliminary step to apply our proposal to mental disorder concepts, we started to develop an OWL ontology of the schizophrenia spectrum, which is as close as possible to the DSM-5 descriptions.

In this chapter I investigate the kinds of changes that psychiatric kinds undergo when they become explanatory targets of areas of sciences that are not “mature” and are in the early stages of discovering mechanisms. The two areas of science that are the targets of my analysis are cognitive neuroscience and cognitive neurobiology.

It is widely agreed that obsessive-compulsive disorder involves irrationality. But where in the complex of states and processes that constitutes OCD should this irrationality be located? A pervasive assumption in both the psychiatric and philosophical literature is that the seat of irrationality is located in the obsessive thoughts characteristic of OCD. Building on a puzzle about insight into OCD (Taylor 2022), we challenge this pervasive assumption, and argue instead that the irrationality of OCD is located in the emotions that (...) are characteristic of OCD, such as anxiety or fear. In particular, we propose to understand the irrationality of OCD as a matter of harboring recalcitrant emotions. We argue that this account not only solves the puzzle about insight, but also makes better sense of how OCD sufferers experience and describe their condition and helps explain some otherwise puzzling features of compulsive behavior.

This contribution focuses on what type of question “Are mental disorders brain disorders?” is and what task Anneli Jefferson performs in her book with the same title. I distinguish between conceptual engineering and conceptual choice, the former involving the individuation of an adequate concept for a specific goal, and the latter involving the normative problem of whether we should employ the concept at hand. I contend that Anneli Jefferson’s book is a work of conceptual engineering, which is valuable in and (...) of itself, but that this is insufficient to answer an equally essential version of the question, “Are mental disorders brain disorders?”, namely, whether we should adopt the newly engineered concept or not, considering a broader range of goals for mental health research and practice.

This paper offers a philosophical analysis of the connection between mental disorder and suicide risk. In contemporary psychiatry, it is commonly suggested that this connection is a causal connection that has been established through empirical discovery. Herein, I examine the extent to which this claim can be sustained. I argue that the connection between mental disorder and increased suicide risk is not wholly causal but is partly conceptual. This in part relates to the way suicidality is built into (...) the definitions of some psychiatric diagnoses. It also relates to the broader normative assumption that suicidal behavior is by definition mentally disordered behavior. The above has significant epistemological implications, which I explore. I propose that the claim that suicide is connected with mental disorder cannot be justified solely by appealing to empirical evidence but also warrants a justification on conceptual and normative grounds.

Josh is a typical 27-year-old in a career that he enjoys and a successful marriage. Josh begins to exhibit the symptoms of a manic episode. He is soon diagnosed with bipolar disorder. While non-manic, Josh’s preferences are typical. While manic, his preferences change dramatically. He quits his job, cheats on his partner, and squanders his savings. These are behaviors that Josh, when non-manic (euthymic), would never agree to. When Josh returns to a euthymic state, he regrets these decisions. Should (...) those close to Josh have prevented him from making these decisions, or does his competence to decide persist despite his acute mania? In this paper, I examine the connections be-tween bipolar disorder and consent. I defend the view that many (although far from all) individuals with bipolar disorder are competent to consent to a wide variety of things when they are in a manic state. This means that mania should not be presumed to undermine competence in clinical settings. -/- I have several goals in this paper. I want to bring philosophy to bear on the connection between consent and bipolar disorder. Additionally, I intend this paper to contribute to the general debate about the conditions of informed consent. Bipolar disorder presents novel challenges to existing conceptions of competence to consent which require stable core of values for an agent to be competent. For example, Buchanan and Brock endorse such a view. In showing that shifting values do not undermine the competence of a person experiencing acute mania, I show that the aforementioned views of competence are false. Overall, this paper makes substantive contributions to the debate about competence to consent and presents the first sustained philosophical treatment of consent among people with bipolar disorder.

The diagnostic category of borderline personality disorder (BPD) has come under increasing criticism in recent years. In this paper, we analyze the role and impact of epistemic injustice, specifically testimonial injustice, in relation to the diagnosis of BPD. We first offer a critical sociological and historical account, detailing and expanding a range of arguments that BPD is problematic nosologically. We then turn to explore the epistemic injustices that can result from a BPD diagnosis, showing how they can lead to (...) experiences of testimonial injustice which impede patient engagement in meaning-making activities, thereby undermining standard therapeutic goals. We conclude by showing how our arguments bolster ongoing efforts to replace the diagnostic category of BPD with alternatives such as complex post-traumatic stress disorder. (shrink)

According to a standard picture of agency, a person’s actions always reflect what they most desire, and many theorists extend this model to mental illness. In this chapter, I pin down exactly where this “volitional” view goes wrong. The key is to recognize that human motivational architecture involves a regulatory control structure: we have both spontaneous states (e.g., automatically-elicited thoughts and action tendencies, etc.) as well as regulatory mechanisms that allow us to suppress or modulate these spontaneous states. Our regulatory (...) abilities, however, are bounded. Mental illnesses, I argue, arise precisely where these bounds are reached, thus allowing inappropriate spontaneous states to regularly manifest in thought and action. I conclude that the volitional view of mental illness is wrong: when a person with mental illness reaches the limits of control, what they do often does not reflect what they most prefer. (shrink)

Sufferers of eating disorders often hold false beliefs about their own body size. Such beliefs appear to violate norms of rationality, being neither grounded by nor responsive to appropriate forms of evidence. I defend the rationality of these beliefs. I argue that they are in fact supported by appropriate evidence, emanating from proprioceptive misperception of bodily boundaries. This argument has far‐reaching implications for the explanation and treatment of eating disorders, as well as debates over the relationship between rationality and human (...) psychology. (shrink)

First-person reports of Major Depressive Disorder reveal that when an individual becomes depressed a profound change or ‘shift’ to one’s conscious experience occurs. The depressed person reports that something fundamental to their experience has been disturbed or shifted; a change associated with the common but elusive claim that when depressed one finds oneself in a ‘different world’ detached from reality and other people. Existing attempts to utilise these phenomenological observations in a psychiatric context are challenged by the fact that (...) this experiential ‘shift’ characteristic of depression appears mysterious and resists analysis in scientific terms. This paper offers a way out of this predicament. The hypothesis proposed is that when an individual becomes depressed, the individual departs from a state of ordinary wakeful consciousness and enters a distinctive global state of consciousness akin to dreaming and the psychedelic state. After unpacking and motivating this hypothesis in the context of research in consciousness science, I outline two of its important implications for the neurobiology of depression and psychedelic psychiatry. The upshot is a promising and conceptually well-motivated hypothesis about depression which is apt for empirical uptake and development. (shrink)

The problems of contemporary states are in large part “affective disorders”; they are failures of states to properly understand and coordinate the emotions of the individuals within and in some instances outside the state. By excluding, imprisoning, and marginalizing members of their societies, states create internal enemies who ultimately enervate their own power and the possibility of peace and freedom within the state. Spinoza’s political theory, based on the notion that the best forms of state are those that coordinate the (...) power and emotions of those within a state, offers us both a diagnosis of and a cure for these affective disorders. In this paper I will outline Spinoza’s notion of the power of the state as a function of the power and coordination of the emotions of its citizens, and show that when the state contracts an affective disorder, such as excessive crime, rebellion, terrorism, etc. the state has failed to properly empower, include and coordinate the passions of the multitude of its citizens and subjects.

Meaning-making plays a central role in how we deal with experiences of suffering, including those due to mental disorder. And for many, religious beliefs, experiences, and practices (hereafter, religious engagement) play a central role in informing this meaning-making. However, a crucial facet of the relationship between experiences of mental disorder and religious engagement remains underexplored—namely the potentially positive effects of mental disorder on religious engagement (e.g. experiences of bipolar disorder increasing sense of God’s presence). In what (...) follows, I will present empirical findings from two recent studies of mine which shed light on the extent to which participants experienced these positive effects, specific components of these effects, and how they fit into their understanding of their mental disorder and its relationship to their religious identity. In doing so, I will draw on and expand Tasia Scrutton’s Potentially Transformative view (2015a, 2015b, 2020) according to which mental disorders may provide opportunities for spiritual growth. My empirical results align with and help deepen an account according to which mental disorders are potentially spiritually transformative by providing further insight into such instances: specifically, which symptoms and internal and external factors are often involved, as well as which religious beliefs, experiences, and/or practices are often affected. After presenting these results and articulating their relevance for a potentially transformative view of mental disorder, I will then address some potential objections to the theoretical account as well as some limitations of the empirical work, before sketching possible promising directions for future research.

This chapter conceptually analyzes the post-traumatic stress injuries called moral injury, moral fatigue or exhaustion, and broken spirit. It then identifies two puzzles. First, soldiers sometimes sustain moral injury even from doing right actions. Second, they experience moral exhaustion from making decisions even where the morally right choice is so obvious that it shouldn’t be stressful to make it; and even where rightness of decision is so murky that no decision could be morally faulted. The injuries result of mistaken moral (...) self-evaluation. Methods of preventing and treating these injuries are defended, including training in self-forgiveness, moral off-loading of actions and decisions to persons and devices less likely to feel inappropriate guilt, and the use of drugs to prevent such guilt. The foregoing has been about moral injury erroneously resulting from the non-violation of a correct moral code. But the chapter then introduces the concept of moral pseudo-injury—felt moral injury that has in reality resulted from violation of a false moral code, so that no one has really been morally injured. This can be used as a method in warfighting. And since the injuries it produces are illusory, this would be morally superior to physical violence. For it causes less injury to its victims, and should cause less guilt in those who must inflict it. Historical precedents are considered. Finally, our enemies often use moral pseudo-injury against us, in the form of terrorist violence against civilians. Terrorism causes comparatively few harms, yet we mistakenly see it as more morally horrific than conventional combat that causes much worse loss of life among armed forces members. Here we need the nuancing and clarifying power of philosophy to restore a sense of proportion, thence to prevent or therapize the moral pseudo-injury we may experience from these sorts of attacks. (This is a pre-penultimate version of the published version, available from OUP at the external link, which contains minor variances. The paper was earlier known as "PTSD Weaponized: A Theory of Moral Injury"; that now superseded version is archived under "past conferences" on the Center for Ethics and the Rule of Law website.).

This review aimed at exploring the psychosocial disorders of Nigeria as a nation, its effect on the citizens and the remedy. Psychosocial disorder is a mental illness induced by life experiences, stress, as well as maladaptive cognitive and behavioural processes. The prevalence of these disorders include depression, schizophrenia, anxiety disorders, substance use disorder, personality disorder and autism spectrum disorders have rapidly increase over the past years in Nigeria with its negative impact on the socioeconomic status, psychological well-being; (...) peaceful coexistence and mental health of the entire society. These have precipitated some social anomalies such as bribery and corruption, antisocial behaviour, religious fanaticism, terrorism and so on. The study therefore recommends the need for government to implement effective mental health interventions program that would facilitate easy access to mental healthcare services in Nigeria. There is also an urgent need to improve the mental health awareness of Nigerians through education and public mental health campaign. (shrink)

I argue that Joseph Raz’s paper on euthanasia faces a problem of coherence with Joseph Raz’s paper addressing the question of “Why should I be moral?”.

Aims: The Research Diagnostic Criteria for Temporomandi¬bular Disorders (RDC/TMD) Axis I diagnostic algorithms were demonstrated to be reliable but below target sensitivity and specificity. Empirical data supported Axis I algorithm revisions that were valid. Axis II instruments were shown to be both reliable and valid. An international consensus workshop was convened to obtain recommendations and finalization of new Axis I diagnostic algorithms and new Axis II instruments. Methods: A comprehensive search of published TMD diagnostic literature was followed by review and (...) consensus via a formal structured process by a panel of experts for revision of the RDC/TMD. Results: The recommended Diagnostic Criteria for TMD (DC/TMD) Axis I protocol includes both a valid screener for pain diagnoses and valid criteria for the most common pain-related TMDs and for one intra-articular disorder. The Axis II protocol retains selected RDC/TMD screening instruments augmented with new instruments to better assess the interactions between pain and psychosocial functioning. A comprehensive classification system is also presented. Conclusion: The recommended evidence-based DC/TMD protocol is appropriate for use in both the clinical and research settings. Simple Axis I and II screening tests augmented by validated Axis I and Axis II instruments allow for identification of simple to complex TMD patients. (shrink)

Evidence-Based Medicine has little consideration for mechanisms and philosophers of science and medicine have recently made pleas to increase the place of mechanisms in the medical evidence hierarchy. However, in this debate the notions of mechanisms seem to be limited to 'mechanistic processes' and 'complex-systems mechanisms,' understood as 'componential causal systems'. I believe that this will not do full justice to how mechanisms are used in biological, psychological and social sciences and, consequently, in a more biopsychosocial approach to medicine. Here, (...) I propose, following (Kuorikoski, 2009), to pay more attention to 'abstract forms of interaction' mechanisms. The present work scrutinized review articles on depression and medically unexplained pain, which are considered to be of multifactorial pathogenesis, for their use of mechanisms. In review articles on these disorders there seemed to be a range of uses between more 'abstract forms of interaction' and 'componential causal system' mechanisms. I therefore propose to expand the notions of mechanisms considered in medicine to include that of more 'abstract forms of interaction' to better explain and manage biopsychosocial disorders.

Although formal thought disorder (FTD) has been for long a clinical label in the assessment of some psychiatric disorders, in particular of schizophrenia, it remains a source of controversy, mostly because it is hard to say what exactly the “formal” in FTD refers to. We see anomalous processing of terminological knowledge, a core construct of human knowledge in general, behind FTD symptoms and we approach this anomaly from a strictly formal perspective. More specifically, we present here a symbolic computational (...) model of storage in, and activation of, a human semantic network, or semantic memory, whose core element is logical form; this is normalized by description logic (DL), namely by CL, a DL-based language – Conception Language – designed to formalize conceptualization from the viewpoint of individual cognitive agency. In this model, disruptions in the rule-based implementation of the logical form account for the apparently semantic anomalies symptomatic of FTD, which are detected by means of a CL-based algorithmic assessment.

Aphantasia is a condition characterised by a deficit of mental imagery. Since several psychopathologies are partially maintained by mental imagery, it may be illuminating to consider the condition against the background of psychological disorder. After outlining current findings and hypotheses regarding aphantasia and psychopathology, this paper suggests that some support for defining aphantasia as a lack of voluntary imagery may be found here. The paper then outlines potentially fruitful directions for future research into aphantasia in general and its relation (...) to psychopathology in particular, including rethinking use of the SUIS to measure involuntary imagery, whether aphantasia offers protection against addiction, and whether hyperphantasia is a potential risk factor for maladaptive daydreaming, among others.

Physical activity levels of people with chronic neurological disorders are lower than those of healthy people. Problems in neurological disorders, including gait abnormalities, muscle weakness/loss of strength, spasticity, tremor, fatigue, balance disorder, and incontinence, results in lower physical activity level. After determining the situations that are contraindicated for physical activity, the patients should be evaluated by physiotherapists, and possible risks that may occur should be determined. Many studies have demonstrated that physical activity significantly reduces mortality and morbidity, increases community (...) participation, and improves health-related quality of life. These benefits show that increased physical activity and exercise should be part of the standard management of neurological disorders. In these patients, physical activity programs should be structured individually by providing appropriate environmental conditions and safety, following the assessment of the functional status and severity of the disease. The duration, intensity, and type of planned physical activity should be adjusted individually; Appropriate rest intervals should be given during the activity, and termination criteria should be determined according to individual tolerance. This literature review aims to provide an up-to-date overview of physical activity recommendations for individuals with chronic neurological disorders. (shrink)

Louis Charland has argued that the Cluster B personality disorders, including borderline personality disorder, are primarily moral rather than clinical conditions. Part of his argument stems from reflections on effective treatment of borderline personality disorder. In the argument from treatment, he claims that successful treatment of all Cluster B personality disorders requires a positive change in a patient’s moral character. Based on this claim, he concludes (1) that these disorders are, at root, deficits in moral character, and (2) (...) that effective treatment of these disorders requires a sort of moral education rather than clinical intervention. In this paper, I evaluate the argument from treatment through a critical analysis of two psychotherapeutic interventions that have shown recent effectiveness against borderline personality disorder. I suggest that both Dialectical Behaviour Therapy and Mentalization-Based Treatment indicate that borderline personality disorder is, at root, a deficit in non-moral cognitive and emotional capacities. I suggest that these non-moral deficits obscure the expression of an otherwise intact moral character. In light of this, I conclude that effective treatment of borderline personality disorder requires primarily clinical intervention rather than moral edification. (shrink)

Advocates of the Person-Centered Healthcare (PCH) approach say that PCH is a response to a failure of caring for patients as persons. Nevertheless, there are many human subjects falling to fulfill the requirements of a traditional philosophical definition of personhood. Hence, if we take, PCH seriously, a greater clarification of the key terminology of PCH is urgently needed. It seems necessary, for instance, that the concept of the person should be extended in order to include those individuals with insipient or (...) immature levels of consciousness, as well as those who are severely and permanently mentally handicapped. In this article, we will depart from some well-known philosophical concepts of what it means to be a person and try to offer a broader and more inclusive meaning. We suggest that persons are human beings with a socially recognized biography, which implies to recognize as persons individuals with necessities, but also with narratives about their interests and claims, expressed sometimes by other people related to them. This is particularly the case of individuals that suffer from severe disorders of consciousness. For those, is not only care that matters; respect matters too. Caregivers should therefore not only sympathetically care for the well-being of these people; they should also be concerned to respect their interests and claims by interpreting them empathetically, in the light of their biographical story. Our conclusion is that, in order to be coherent, PCH must consider individuals with severe disorders of consciousness as persons and we think that our revised concept of personhood fits with this requirement.

Jerome Wakefield has argued that a disorder is a harmful dysfunction. This paper develops how Wakefield should construe harmful in his harmful dysfunction analysis. Recently, Neil Feit has argued that classic puzzles involved in analyzing harm render Wakefield’s HDA better off without harm as a necessary condition. Whether or not one conceives of harm as comparative or non-comparative, the concern is that the HDA forces people to classify as mere dysfunction what they know to be a disorder. For (...) instance, one can conceive of cases where simultaneous disorders prevent each other from being, in any traditional sense, actually harmful; in such cases, according to the HDA, neither would be a disorder. I argue that the sense of harm that Wakefield should employ in the HDA is dispositional, similar to the sense of harm used when describing a vile of poison: “Be careful! That’s poison. It’s harmful.” I call this harm in the damage sense. Using this sense of harm enables the HDA to avoid Feit’s arguments, and thus it should be preferred to other senses when analyzing harmful dysfunction. (shrink)

A pressing need for interrater reliability in the diagnosis of mental disorders emerged during the mid-twentieth century, prompted in part by the development of diverse new treatments. The Diagnostic and Statistical Manual of Mental Disorders (DSM), third edition answered this need by introducing operationalized diagnostic criteria that were field-tested for interrater reliability. Unfortunately, the focus on reliability came at a time when the scientific understanding of mental disorders was embryonic and could not yield valid disease definitions. Based on accreting problems (...) with the current DSM-fourth edition (DSM-IV) classification, it is apparent that validity will not be achieved simply by refining criteria for existing disorders or by the addition of new disorders. Yet DSM-IV diagnostic criteria dominate thinking about mental disorders in clinical practice, research, treatment development, and law. As a result, the modernDSMsystem, intended to create a shared language, also creates epistemic blinders that impede progress toward valid diagnoses. Insights that are beginning to emerge from psychology, neuroscience, and genetics suggest possible strategies for moving forward. (shrink)

In this paper, I am generally concerned with certain mental disorders and the doxastic attitudes that sometimes characterize them. According to recent Anglo-American philosophical studies on this topic, the latter involve beliefs that have somehow “gone wrong”: strange or irrational beliefs and cases of “motivated irrationality”. I aim to focus on pathological and deceptive phenomena such as delusion and self-deception. From a phenomenological perspective, these can also be investigated with regard to their experiential content. Adopting this approach, and starting in (...) particular with the eidetic connection between the living body and its own environment, I will examine disorders of the ecological self. Psychiatric delusion, which is at the core of this examination, is a symptom of a great number of mental disorders, such as Capgras disorder, Cotard disorder and schizophrenia. Integrating dominant (propositional) models of delusion which reduce this pathological phenomenon to a certain kind of belief, I propose an eco-phenomenological understanding of its contours. From this perspective, delusion reveals itself primarily as an illusory experience: a delusional value-perception. In particular, I offer a Schelerian-based description of a peculiar case of delusion: Capgras delusion. People who suffer from Capgras delusion claim that an otherwise familiar individual has been replaced by an impostor. I consider, although in its negative variations, the contextual (rather than internalist) character of this type of delusion. (shrink)

In a recent study, we found a negative association between psychopathy and violence against genetic relatives. We interpreted this result as a form of nepotism and argued that it failed to support the hypothesis that psychopathy is a mental disorder, suggesting instead that it supports the hypothesis that psychopathy is an evolved life history strategy. This interpretation and subsequent arguments have been challenged in a number of ways. Here, we identify several misunderstandings regarding the harmful dysfunction definition of mental (...) disorder as it applies to psychopathy and regarding the meaning of nepotism. Furthermore, we examine the evidence provided by our critics that psychopathy is associated with other disorders, and we offer a comment on their alternative model of psychopathy. We conclude that there remains little evidence that psychopathy is the product of dysfunctional mechanisms. (shrink)

People suffering from Obsessive-Compulsive Disorder (OCD) do things they do not want to do, and/or they think things they do not want to think. In about 10 percent of OCD patients, none of the available treatment options is effective. A small group of these patients is currently being treated with deep brain stimulation (DBS). Deep brain stimulation involves the implantation of electrodes in the brain. These electrodes give a continuous electrical pulse to the brain area in which they are (...) implanted. It turns out that patients may experience profound changes as a result of DBS treatment. It is not just the symptoms that change; patients rather seem to experience a different way of being in the world. These global effects are insufficiently captured by traditional psychiatric scales, which mainly consist of behavioural measures of the severity of the symptoms. In this article we aim to capture the changes in the patients’ phenomenology and make sense of the broad range of changes they report. For that we introduce an enactive, affordance-based model that fleshes out the dynamic interactions between person and world in four aspects. The first aspect is the patients’ experience of the world. We propose to specify the patients’ world in terms of a field of affordances, with the three dimensions of broadness of scope (‘width’ of the field), temporal horizon (‘depth’), and relevance of the perceived affordances (‘height’). The second aspect is the person-side of the interaction, that is, the patients’ self-experience, notably their moods and feelings. Thirdly, we point to the different characteristics of the way in which patients relate to the world. And lastly, the existential stance refers to the stance that patients take towards the changes they experience: the second-order evaluative relation to their interactions and themselves. With our model we intend to specify the notion of being in the world in order to do justice to the phenomenological effects of DBS treatment. (shrink)

Impairment of self-control is often said to be a defining feature of addiction. Yet many addicts display what appears to be a considerable amount of control over their drug-oriented actions. Not only are their actions clearly intentional and frequently carried out in a conscious and deliberate manner, there is evidence that many addicts are responsive to a wide range of ordinary incentives and counter-incentives. Moreover, addicts have a wide variety of reasons for using drugs, reasons which often seem to go (...) a long way towards explaining their drug-oriented behavior. Many use drugs, for example, to cope with stressful or traumatic experiences. In this article I argue that some standard philosophical explanations of addicts’ impairment of self-control are inadequate, and propose an alternative. (shrink)

Deep Brain Stimulation (DBS) is a relatively new, experimental treatment for patients suffering from treatment-refractory Obsessive Compulsive Disorder (OCD). The effects of treatment are typically assessed with psychopathological scales that measure the amount of symptoms. However, clinical experience indicates that the effects of DBS are not limited to symptoms only: patients for instance report changes in perception, feeling stronger and more confident, and doing things unreflectively. Our aim is to get a better overview of the whole variety of changes (...) that OCD patients experience during DBS treatment. For that purpose we conducted in-depth, semi-structured interviews with 18 OCD patients. In this paper, we present the results from this qualitative study.We list the changes grouped in four domains: with regard to (a) person, (b) (social) world, (c)characteristics of person-world interactions, and (d) existential stance. We subsequently provide an interpretation of these results. In particular, we suggest that many of these changes can be seen as different expressions of the same process; namely that the experience of anxiety and tension gives way to an increased basic trust and increased reliance on one’s abilities. We then discuss the clinical implications of our findings, especially with regard to properly informing patients of what they can expect from treatment, the usefulness of including CBT in treatment, and the limitations of current measures of treatment success. We end by making several concrete suggestions for further research. (shrink)

Does DBS change a patient’s personality? This is one of the central questions in the debate on the ethics of treatment with Deep Brain Stimulation (DBS). At the moment, however, this important debate is hampered by the fact that there is relatively little data available concerning what patients actually experience following DBS treatment. There are a few qualitative studies with patients with Parkinson’s disease and Primary Dystonia and some case reports, but there has been no qualitative study yet with patients (...) suffering from psychiatric disorders. In this paper, we present the experiences of 18 patients with Obsessive-Compulsive Disorder (OCD) who are undergoing treatment with DBS. We will also discuss the inherent difficulties of how to define and assess changes in personality, in particular for patients with psychiatric disorders. We end with a discussion of the data and how these shed new light on the conceptual debate about how to define personality. (shrink)

The tendency to draw mind-brain dichotomies and evaluate mental disorders dualistically arises in both laypeople and mental health professionals, leads to biased judgments, and contributes to mental health stigmatization. This paper offers a theory identifying an underlying source of these evaluations in social practice. According to this theory, dualistic evaluations are rooted in two mechanisms by which we represent and evaluate the beliefs of others in folk psychology and theory of mind: the doxastic conception of mental disorders and doxastic voluntarism. (...) Tracing these origins contributes to our understanding of mental state representation in cognitive science and philosophy of psychiatry, the concept of belief in philosophy of mind, and may help improve patient experience and treatment in light of social stigmatization and bias toward mental illness.

Externalist theories hold that a comprehensive understanding of mental disorder cannot be achieved unless we attend to factors that lie outside of the head: neural explanations alone will not fully capture the complex dependencies that exist between an individual’s psychiatric condition and her social, cultural, and material environment. Here, we firstly offer a taxonomy of ways in which the externalist viewpoint can be understood, and unpack its commitments concerning the nature and physical realization of mental disorder. Secondly, we (...) apply a strongly externalist approach to the case of Autistic Spectrum Disorder, and argue that this condition can be illuminated by appeal to the hypothesis of extended cognition. We conclude by briefly considering the significance this strongly externalist approach may have for psychiatric practice and pedagogy. (shrink)

As it emerged from philosophical analyses and cognitive research, most concepts exhibit typicality effects, and resist to the efforts of defining them in terms of necessary and sufficient conditions. This holds also in the case of many medical concepts. This is a problem for the design of computer science ontologies, since knowledge representation formalisms commonly adopted in this field do not allow for the representation of concepts in terms of typical traits. However, the need of representing concepts in terms of (...) typical traits concerns almost every domain of real world knowledge, including medical domains. In particular, in this article we take into account the domain of mental disorders, starting from the DSM-5 descriptions of some specific mental disorders. On this respect, we favor a hybrid approach to the representation of psychiatric concepts, in which ontology oriented formalisms are combined to a geometric representation of knowledge based on conceptual spaces.

Naturalistic accounts of mental disorder aim to identify an objective basis for attributions of mental disorder. This goal is important for demarcating genuine mental disorders from artificial or socially constructed disorders. The articulation of a demarcation criterion provides a means for assuring that attributions of 'mental disorder' are not merely pathologizing different forms of social deviance. The most influential naturalistic and hybrid definitions of mental disorder identify biological dysfunction as the objective basis of mental disorders: genuine (...) mental... (shrink)

Deep brain stimulation (DBS), a surgical procedure involving the implantation of electrodes in the brain, has rekindled the medical community’s interest in psychosurgery. Whereas many researchers argue DBS is substantially different from psychosurgery, we argue psychiatric DBS—though a much more precise and refined treatment than its predecessors—is nevertheless a form of psychosurgery, which raises both old and new ethical and legal concerns that have not been given proper attention. Learning from the ethical and regulatory failures of older forms of psychosurgery (...) can help shed light on how to address the regulatory gaps that exist currently in DBS research. To show why it is important to address the current regulatory gaps within psychiatric DBS, we draw on the motivations underlying the regulation of earlier forms of psychosurgery in the US. We begin by providing a brief history of psychosurgery and electrical brain stimulation in the US. Against this backdrop, we introduce psychiatric DBS, exploring current research and ongoing clinical trials. We then draw out the ethical and regulatory similarities between earlier forms of psychosurgery and psychiatric DBS. As we will show, the factors that motivated strict regulation of earlier psychosurgical procedures mirror concerns with psychiatric DBS today. We offer three recommendations for psychiatric DBS regulation, which echo earlier motivations for regulating psychosurgery, along with new considerations that reflect the novel technologies used in DBS.

I argue that, according to Plato, the body is the sole cause of psychic disorders. This view is expressed at Timaeus 86b in an ambiguous sentence that has been widely misunderstood by translators and commentators. The goal of this article is to offer a new understanding of Plato’s text and view. In the first section, I argue that although the body is the result of the gods’ best efforts, their sub-optimal materials meant that the soul is constantly vulnerable to the (...) body’s influences. In the second section, I argue that every psychic disorder is a disruption of the motions of the inner psychic circles by the body; moreover, I defend my translation of 86b. In the final section, I argue that the goal of education is to restore the circles to their original orbits, and I disarm a possible objection that bad education is also a cause of psychic disorder.

Autism spectrum disorder is characterised by differences in unimodal and multimodal sensory and proprioceptive processing, with complex biases towards local over global processing. Many of these elements are implicated in versions of the rubber hand illusion, which were therefore studied in high-functioning individuals with ASD and a typically developing control group. Both groups experienced the illusion. A number of differences were found, related to proprioception and sensorimotor processes. The ASD group showed reduced sensitivity to visuotactile-proprioceptive discrepancy but more accurate (...) proprioception. This group also differed on acceleration in subsequent reach trials. Results are discussed in terms of weak top-down integration and precision-accuracy trade-offs. The RHI appears to be a useful tool for investigating multisensory processing in ASD. (shrink)

We present results from a single case study based on semi-structured interviews with a student (a boy in school year 3) diagnosed with autism spectrum disorder and his school staff after participating in a short and small-scale intervention carried out in a socio-economically disadvantaged Swedish elementary school in 2019. The student participated in a seven week long intervention with a total of 12 philosophical dialogues (ranging from 45 to 60 minutes). Two facilitators, both with years of facilitation experience and (...) teacher degree and at least BA in philosophy, facilitated the majority of the dialogues and mainly followed a ”routine” procedure. The student was interviewed in direct connection to the end of the intervention about his experiences from the dialogues and his perceptions about whether and how the dialogues had influenced him. The student’s two teachers, who had participated in the dialogues as participants, were interviewed as a pair, also in direct connection to the end of the intervention, while the school principal was interviewed two years after the study. These staff interviews concerned the staff’s experiences of the influence of the dialogues on the students within the intervention as well as transfer effects to other contexts in school. The data from the study include detailed elaborations from a student perspective of different effects on the student’s communicative and cognitive development, which are in several respects supported also by staff reports. The results show that the student was able, interested, and willing to participate in philosophical dialogues, and our data point to several positive outcomes for the student in the communicative and cognitive domains.

A striking feature of post-modernism is its distrust of the subject. If the modern period, beginning with Descartes, sought in the subject a source of certainty, an Archimedian point from which all else could be derived, post- modernism has taken the opposite tack. Rather than taking the self as a foundation, it has seen it as founded, as dependent on the accidents which situate consciousness in the world. The same holds for the unity of the subject. Modernity, in its search (...) for a single foundation, held the subject to be an indissoluble unity. Post-modernism’s position, by contrast, is announced by Nietzsche: “The assumption of one single subject is perhaps unnecessary; perhaps it is just as permissible to assume a multiplicity of subjects, whose interaction and struggle is the basis of our thought and our consciousness in general? ...My hypotheses: The subject as multiplicity.” Given this, there is a natural correspondence between the success of post- modernism and the current interest in multiple personality disorder. In the latter, we actually have the experience of a “multiplicity of subjects” in their interaction and struggle. The subject stands there before us “as multiplicity.” It gives us a concrete case, one which raises some of the pressing questions associated with the post-modern denial of the subject. Confronting it, we ask: how real are the personalities composing the multiplicity of this disordered self? What, in fact, does this multiplicity tell us about the self? about its genesis and status? What does it reveal about “our thought and consciousness in general”? I plan, in the short compass of this paper, to sketch some answers to these questions. §1. A brief description of MPD. The American Psychiatric Association gives two criteria for (MPD) multiple personality disorder. First, and most obviously, there is “the existence within the person of two or more distinct personalities or personality states (each with its own relatively enduring pattern. (shrink)

Disorders of consciousness include coma, the vegetative state and the minimally conscious state. Such patients are often regarded as unconscious. This has consequences for end of life decisions for these patients: it is much easier to justify withdrawing life support for unconscious than conscious patients. Recent brain imaging research has however suggested that some patients may in fact be conscious.

The mental disorder concept has not been paid due attention to. The aim of this paper is twofold: first, to assess how much space has been given to the mental disorder concept in textbooks of psychiatry, and second, to show in how many domains both within and beyond psychiatry the mental disorder concept plays a key role. A number of textbooks written in English, German, French, Spanish, and Italian, selected as examples, have been scanned so as to (...) see if there is a chapter dealing with mental disorder, in particular with its definition. Also, the fields in which the mental disorder plays a major role have been identified, and the reasons why the concept of mental disorder is relevant for them have been explored. There is no chapter dealing with the definition of mental disorder in some textbooks of psychiatry in English, German, French, Spanish, and Italian that have been selected as examples. Yet there are numerous domains, directly or indirectly related to psychiatry, in which the mental disorder concept is a substantial element. The results show that the concept of mental disorder should be kept high on psychiatric agenda and given due space in textbooks of psychiatry accordingly. (shrink)

In view of the publication of the DSM-V researchers were asked to discuss the theoretical implications of the definition of mental disorders. The reasons for the use, in the DSM-III, of the term disorder instead of disease are considered. The analysis of these reasons clarifies the distinction between the general definition of disorder and its implicit, technical meaning which arises from concrete use in DSM disorders. The characteristics and limits of this technical meaning are discussed and contrasted to (...) alternative definitions, like Wakefield’s harmful/dysfunction analysis. It is shown that Wakefield’s analysis faces internal theoretical problems in addition to practical limits for its acceptance in the DSM-V. In particular, it is shown that: a) the term dysfunction is not purely factual but intrinsically normative/evaluative; b) it is difficult to clarify what dysfunctions are in the psychiatric context (the dysfunctional mechanism involved being unknown in most cases and the use of evolutionary theory being even more problematic); c) the use of conceptual analysis and commonsense intuition to define dysfunctions leaves unsatisfied empiricists; d) it is unlikely that the authors of the DSM-V will accept Wakefield’s suggestion to revise the diagnostic criteria of any single DSM disorder in accordance with his analysis, because this is an excessively extensive change and also because this would probably reduce DSM reliability. In conclusion, it is pointed up in which sense DSM mental disorders have to be conceived as constructs, and that this undermines the realistic search for a clear-cut demarcation criterion between what is disorder and what is not.

In this peer commentary on L. Syd M. Johnson’s “Inference and Inductive Risk in Disorders of Consciousness,” I argue for the necessity of disability education as an integral component of decision-making processes concerning patients with DOC and, mutatis mutandis, all patients with disabilities. The sole qualification Johnson places on such decision-making is that stakeholders are educated about and “understand the uncertainties of diagnosis and prognosis.” Drawing upon research in philosophy of disability, social epistemology, and health psychology, I argue that this (...) educational qualification is insufficient to address systemic ableism and other forms of epistemic bias in quality of life judgments.

Body Integrity Identity Disorder (BIID) is a very rare condition describing those with an intense desire or need to move from a state of ability to relative impairment, typically through the amputation of one or more limbs. In this paper, I draw upon research in critical disability studies and philosophy of disability to critique arguments based upon the principle of nonmaleficence against such surgery. I demonstrate how the action-relative concept of harm in such arguments relies upon suspect notions of (...) biological and statistical normality, and I contend that each fail to provide normative guidance. I then propose a critical theory of harm, one marked by substantive engagement with both empirical and reflective inquiry across the sciences, social sciences, and humanities. I conclude by discussing the implications of this theory and how it might enrich ongoing debates in bioethics, philosophy of disability, and the health humanities. (shrink)

Although enactive approaches to cognition vary in terms of their character and scope, all endorse several core claims. The first is that cognition is tied to action. The second is that cognition is composed of more than just in-the-head processes; cognitive activities are externalized via features of our embodiment and in our ecological dealings with the people and things around us. I appeal to these two enactive claims to consider a view called “direct social perception” : the idea that we (...) can sometimes perceive features of other minds directly in the character of their embodiment and environmental interactions. I argue that if DSP is true, we can probably also perceive certain features of mental disorders as well. I draw upon the developmental psychologist Daniel Stern’s notion of “forms of vitality”—largely overlooked in these debates—to develop this idea, and I use autism as a case study. I argue further that an enactive approach to DSP can clarify some ways we play a regulative role in shaping the temporal and phenomenal character of the disorder in question, and it may therefore have practical significance for both the clinical and therapeutic encounter.

In this paper we argue that dissociative identity disorder (DID) is best interpreted as a causal model of a (possible) post-traumatic psychological process, as a mechanical model of an abnormal psychological condition. From this perspective we examine and criticize the evidential status of DID, and we demonstrate that there is really no good reason to believe that anyone has ever suffered from DID so understood. This is so because the proponents of DID violate basic methodological principles of good causal (...) modeling.

Many who suffer from eating disorders claim that they see themselves as “fat”. Despite decades of research into the phenomenon, behavioural evidence has failed to confirm that eating disorders involve visual misperception of own-body size. I illustrate the importance of this phenomenon for our understanding of perceptual processing, outline the challenges involved in experimentally confirming it, and provide solutions to those challenges.

In this paper, I present a challenge for Michael McKenna’s conversational theory of moral responsibility. On his view, to be a responsible agent is to be able to engage in a type of moral conversation. I argue that individuals with autism spectrum disorder present a considerable problem for the conversational theory because empirical evidence on the disorder seems to suggest that there are individuals in the world who meet all of the conditions for responsible agency that the theory (...) lays out but who are nevertheless not responsible agents. Attending to the moral psychology of such individuals will, I think, help shed light on an important gap in the conversational theory. (shrink)
