In psychiatry, pharmacological drugs play an important experimental role in attempts to identify the neurobiological causes of mental disorders. Besides being developed in applied contexts as potential treatments for patients with mental disorders, pharmacological drugs play a crucial role in research contexts as experimental instruments that facilitate the formulation and revision of neurobiological theories of psychopathology. This paper examines the various epistemic functions that pharmacological drugs serve in the discovery, refinement, testing, and elaboration of neurobiological theories of mental disorders. I (...) articulate this thesis with reference to the history of antipsychotic drugs and the evolution of the dopamine hypothesis of schizophrenia in the second half of the twentieth century. I argue that interventions with psychiatric patients through the medium of antipsychotic drugs provide researchers with information and evidence about the neurobiological causes of schizophrenia. This analysis highlights the importance of pharmacological drugs as research tools in the generation of psychiatric knowledge and the dynamic relationship between practical and theoretical contexts in psychiatry.

Since the turn of the twenty-first century, biomedical psychiatry around the globe has embraced the so-called precision medicine paradigm, a model for medical research that uses innovative techniques for data collection and analysis to reevaluate traditional theories of disease. The goal of precision medicine is to improve diagnostics by restratifying the patient population on the basis of a deeper understanding of disease processes. This paper argues that precision is ill-fitting for psychiatry for two reasons. First, in psychiatry, unlike in fields (...) like oncology, precision medicine has been understood as an attempt to improve medicine by casting out, rather than merely revising, traditional taxonomic tools. Second, in psychiatry the term “biomarker” is often used in reference to signs or symptoms that allow patients to be classified and then matched with treatments; however, in oncology “biomarker” usually refers to a disease mechanism that is useful not only for diagnostics, but also for discovering causal pathways that drug therapies can target. Given these differences between how the precision medicine paradigm operates in psychiatry and in other medical fields like oncology, while precision psychiatry may offer successful rhetoric, it is not a promising paradigm.

A significant portion of the scholarship in analytic philosophy of psychiatry has been devoted to the problem of what kind of kind psychiatric disorders are. Efforts have included descriptive projects, which aim to identify what psychiatrists in fact refer to when they diagnose, and prescriptive ones, which argue over that to which diagnostic categories should refer. In other words, philosophers have occupied themselves with what I call “diagnostic kinds”. However, the pride of place traditionally given to diagnostic kinds in psychiatric (...) research has recently come under attack, most notably by a recent initiative of the National Institute of Mental Health, the Research Domain Criteria Project, that seeks to exclude diagnostic categories from experimental designs and focus on other sorts of psychiatric kinds. I argue that philosophical accounts privileging diagnostic kinds must respond to this new line of criticism, and conclude that philosophers need to either counter psychiatrists’ growing suspicion about the hegemony of diagnostic categories in the clinic and the laboratory, or join in redirecting their efforts toward the development of robust accounts of other sorts of psychiatric objects and processes.

The failure of psychiatry to validate its diagnostic constructs is often attributed to the prioritizing of reliability over validity in the structure and content of the Diagnostic and Statistical Manual of Mental Disorders. Here I argue that in fact what has retarded biomedical approaches to psychopathology is unwarranted optimism about diagnostic discrimination: the assumption that our diagnostic tests group patients together in ways that allow for relevant facts about mental disorder to be discovered. I consider the Research Domain Criteria framework (...) as a new paradigm for classifying objects of psychiatric research that solves some of the challenges brought on by this assumption. (shrink)

Depression is a widespread and debilitating disorder, but developing effective treatments has proven challenging. Despite success in animal models, many treatments fail in human trials. While various factors contribute to this translational failure, standardization practices in animal research are often overlooked. This paper argues that certain standardization choices in behavioral neuroscience research on depression can limit the generalizability of results from rodents to humans. This raises ethical and scientific concerns, including animal waste and a lack of progress in treating human (...) patients. To address these issues, animal ethics committees can establish reasonable expectations for preclinical research and highlight the impact of standardization on generalizability. Such efforts can help improve translation from animal models to human patients and ultimately benefit those suffering from depression. (shrink)

‘Cosmetic psychopharmacology’ is a term coined by Peter Kramer in his 1993 best‐seller, Listening to Prozac. It has come to refer to the use of psychoactive substances to effect changes in function for conditions that are either normal or subclinical variants. In this paper, I ask: What distinguishes an existential ailment from clinical depression, or either of those from normal depressed mood, melancholic temperament, dysthymia or other depressive disorders? Can we reliably distinguish one from the other? Are the boundaries of (...) illness and disorder really so distinct? If not, how can we know that treatment of ‘depression’ with Prozac in any given instance constitutes a cosmetic as opposed to, say, a medical or clinical use of psychopharmacology – a distinction that seems to turn on our ability to clearly differentiate the clinical from the cosmetic. If we cannot reliably distinguish between such conditions, can we even have a cosmetic psychopharmacology that is not a form of malpractice, broadly speaking? What if we unplugged Prozac from all the amplitude and hype that resulted in Listening to Prozac becoming an instant best‐seller and simply asked whether or not we can clearly distinguish an appropriate cosmetic use of Prozac for ‘depression’ from an inappropriate cosmetic use of Prozac, and both of those from Prozac's appropriate clinical, that is, non‐cosmetic uses? If we cannot make these distinctions, perhaps it is too early to say there can be such a thing as a cosmetic psychopharmacology. (shrink)

In somatic medicine, diagnostic terms often refer to the disease processes that are the causes of patients' symptoms. The language used in some clinical textbooks and health information resources suggests that this is also sometimes assumed to be the case with diagnoses in psychiatry. However, this seems to be in tension with the ways in which psychiatric diagnoses are defined in diagnostic manuals, according to which they refer solely to clusters of symptoms. This paper explores how theories of reference in (...) the philosophy of language can help to resolve this tension. After the evaluation of descriptive and causal theories of reference, I put forward a conceptual framework based on two-dimensional semantics that allows the causal analysis of diagnostic terms in psychiatry, while taking seriously their descriptive definitions in diagnostic manuals. While the framework is presented as a solution to a problem regarding the semantics of psychiatric diagnoses, it can also accommodate the analysis of diagnostic terms in other medical disciplines.

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.

The subject of this paper is the problematisation of depression in today’s mental health care. It is based on a study of the professional discussion on depression in Finland from the mid-1980s to the 1990s. The ways in which Finnish mental health experts define the object of depression treatment bring out an ambivalence that stems from the discrepancy between two parallel but incongruent notions of what depression is: the psychopharmacological and the psychotherapeutic. The analysis of the discussion demonstrates how clinical (...) and practical rationales of today’s mental health care are formed in the space between the two poles. Two tendencies of these rationales are also pointed out: first, the DSM paradigm of depressive illness inclines to become problematic and to dissolve in the actual practices. Second, they insinuate emphasis on antidepressant medication and overall neuropsychiatric approach in the treatment of depressive disorders, although in an ambivalent way. (shrink)

Mental disorders are assessed globally using the World Health Organization's International Classification of Diseases Classification of Mentaland Behavioural Disorders (ICD), which is largely modeled after (though it also influences) the American Psychiatric Association's Diagnostic and Statistical Manual (DSM) used in the United States. Situated within the scientific narrative of American psychiatry, disorders are typically viewed by practitioners who use the DSM and ICD as essential categories of human experience, with internal, purely descriptive, value-free conditions. Criteria identified in the DSM and (...) ICD describe the behaviors and psychological experiences that manifest from these internal conditions. In .. (shrink)

The scientific model of mental disorder, which is the foundation of American psychiatry, is easily imperialistic when it is applied globally. This unwarranted extension of power is especially problematic for women, since psychiatry is easily used to deny women discursive and agential power and to ignore social and political contexts for women’s suffering. By analyzing the epistemic function of narratives, I argue that the hegemonic power of the scientific narrative is unjustified and often harmful, and that a more accurate and (...) more justly applied understanding of disorder requires accounting for alternative cultural narratives as well.

This article does not directly consider the feelings and emotions that occur in mental illness. Rather, it concerns a higher level methodological question: To what extent is an analysis of feelings and felt emotions of importance for psychiatric classification? Some claim that producing a phenomenologically informed descriptive psychopathology is a prerequisite for serious taxonomic endeavor. Others think that classifications of mental disorders may ignore subjective experience. A middle view holds that classification should at least map the contours of the phenomenology (...) of mental illness. This article examines these options. I conclude that it is not true that phenomenology is a logical prerequisite for classification, nor even that classification should necessarily respect phenomenological boundaries, but that detailed phenomenological examination can sometimes inform classification.

This paper asks what it means to say that a disorder is a “real” disorder and then considers whether culture-bound syndromes are real disorders. Following J.L. Austin I note that when we ask whether some supposed culture-bound syndrome is a real disorder we should start by specifying what possible alternatives we have in mind. We might be asking whether the reported behaviours genuinely occur, that is, whether the culture-bound syndrome is a genuine phenomenon as opposed to a myth. We might (...) be wondering whether the condition should rightly be considered a disorder, as opposed to some sort of non-disorder condition. We might want to know whether the culture-bound syndrome is really a distinct disorder, in the sense that scientific classification systems should include it as a separate category, or whether it is just a variant of a universally occurring disorder. I argue that some specific difficulties can arise with determining whether a culture-bound syndrome is a real disorder in each of these three senses. However, the frequent assumption that real disorders will necessarily occur universally, and that those that occur only in certain environments are suspicious is not generally justified. (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)
