Philosophy of psychiatry: theoretical advances and clinical implications.

Work at the intersection of philosophy and psychiatry has an extensive and influential history, and has received increased attention recently, with the emergence of professional associations and a growing literature. In this paper, we review key advances in work on philosophy and psychiatry, and their related clinical implications. First, in understanding and categorizing mental disorder, both naturalist and normativist considerations are now viewed as important - psychiatric constructs necessitate a consideration of both facts and values. At a conceptual level, this integrative view encourages moving away from strict scientism to soft naturalism, while in clinical practice this facilitates both evidence-based and values-based mental health care. Second, in considering the nature of psychiatric science, there is now increasing emphasis on a pluralist approach, including ontological, explanatory and value pluralism. Conceptually, a pluralist approach acknowledges the multi-level causal interactions that give rise to psychopathology, while clinically it emphasizes the importance of a broad range of "difference-makers", as well as a consideration of "lived experience" in both research and practice. Third, in considering a range of questions about the brain-mind, and how both somatic and psychic factors contribute to the development and maintenance of mental disorders, conceptual and empirical work on embodied cognition provides an increasingly valuable approach. Viewing the brain-mind as embodied, embedded and enactive offers a conceptual approach to the mind-body problem that facilitates the clinical integration of advances in both cognitive-affective neuroscience and phenomenological psychopathology.

Conceptual competence in psychiatric training: building a culture of conceptual inquiry.

Building a culture of conceptual inquiry in psychiatric training requires the development of conceptual competence: the ability to identify and examine assumptions that constitute the philosophical foundations of clinical care and scientific investigation in psychiatry. In this article, we argue for the importance of such competence and illustrate approaches to instilling it through examples drawn from our collective experiences as psychiatric educators.

A Comparative Study on Mental Disorder Conceptualization: A Cross-Disciplinary Analysis.

The conceptualization of mental disorders varies among professionals, impacting diagnosis, treatment, and research. This cross-disciplinary study aimed to understand how various professionals, including psychiatrists, psychologists, medical students, philosophers, and social sciences experts, perceive mental disorders, their attitudes towards the disease status of certain mental states, and their emphasis on biological versus social explanatory attributions. A survey of 371 participants assessed their agreement on a variety of conceptual statements and the relative influence of biological or social explanatory attribution for different mental states. Our findings revealed a consensus on the need for multiple explanatory perspectives in understanding psychiatric conditions and the influence of social, cultural, moral, and political values on diagnosis and classification. Psychiatrists demonstrated balanced bio-social explanatory attributions for various mental conditions, indicating a potential shift from the biological attribution predominantly observed among medical students and residents in psychiatry. Further research into factors influencing these differing perspectives is necessary.

Principles and procedures for revising the hierarchical taxonomy of psychopathology.

Quantitative, empirical approaches to establishing the structure of psychopathology hold promise to improve on traditional psychiatric classification systems. The Hierarchical Taxonomy of Psychopathology (HiTOP) is a framework that summarizes the substantial and growing body of quantitative evidence on the structure of psychopathology. To achieve its aims, HiTOP must incorporate emerging research in a systematic, ongoing fashion. In this article, we describe the historical context and grounding of the principles and procedures for revising the HiTOP framework. Informed by strengths and shortcomings of previous classification systems, the proposed revisions protocol is a formalized system focused around three pillars: (a) prioritizing systematic evaluation of quantitative evidence by a set of transparent criteria and processes, (b) balancing stability with flexibility, and (c) promoting inclusion over gatekeeping in all aspects of the process. We detail how the revisions protocol will be applied in practice, including the scientific and administrative aspects of the process. Additionally, we describe areas of the HiTOP structure that will be a focus of early revisions and outline challenges for the revisions protocol moving forward. The proposed revisions protocol is designed to ensure that the HiTOP framework reflects the current state of scientific knowledge on the structure of psychopathology and fulfils its potential to advance clinical research and practice.

What Should Clinicians Know About Palliative Psychopharmacology?

The nature and scope of palliative psychiatry and associated ethical implications are debated in the literature. This article examines conceptual limitations of extant accounts of palliative psychiatry, with a focus on psychopharmacological practice, and suggests that modifiable and unmodifiable psychiatric illnesses exist on a spectrum along which broader or narrower palliative psychiatric care approaches can be outlined. The article also discusses how these approaches intersect with questions about whether and to what extent psychiatric medications have symptom-reducing or disease-modifying effects. The discussion leads to the conclusion that clinicians are ethically obliged to distinguish among and clearly formulate goals of care in a dynamic and ongoing process of shared decision making with patients.

Addressing the Mental Health Crisis in Youth-Sick Individuals or Sick Societies?

This Viewpoint examines whether increased anxiety and depression among youth is a true epidemic of psychiatric disorders or a reflection of sociopolitical adversity and disorganization.

Beyond Binary Narratives of Mental Health Advocacy: Latent Profiles of Mental Health Activists and Advocates With Lived Experience.

OBJECTIVE: In this article, the authors used data from a national survey of mental health activists and advocates (MHAAs) with lived experience of psychiatric disabilities to investigate attitudes toward psychiatric care. METHODS: The authors distributed a survey, developed by a team led by researchers who were also service users, to both mainstream and more critical advocacy groups and networks (N=547 participants), and they analyzed the data by using latent class analysis (LCA). Four survey variables regarding beliefs about involuntary hospitalization, assisted outpatient treatment, medication, and diagnosis were used to generate latent subgroups. The authors explored associations between key survey variables and latent classes with chi-square tests and analysis of variance. RESULTS: LCA indicated an optimal six-class solution. The classes existed on a spectrum of positions, ranging from highly favorable views of traditional psychiatric practices to highly critical views, with classes in the middle representing distinct profiles of attitudes toward treatment and diagnosis. Significant between-group differences were found for participants' psychiatric treatment histories, motivations to engage in activism and advocacy, and views about mental health care and advocacy priorities. CONCLUSIONS: Findings reveal considerable heterogeneity among MHAAs and challenge binary narratives of mental health advocacy.

The State of the Catatonia Literature: Employing Bibliometric Analysis of Articles From 1965-2020 to Identify Current Research Gaps.

BACKGROUND: Since Kahlbaum's classic 19th-century description of catatonia, our conceptualization of this syndrome, as well treatment options for it, has advanced considerably. However, little is known about the current state of the catatonia literature since a comprehensive bibliometric analysis of it has not yet been undertaken. OBJECTIVE: The purpose of this study was to conduct a bibliometric analysis, along with a content analysis of articles reporting new findings, to better understand the catatonia literature and how catatonia research is changing. METHODS: Using the search term "Title(catatoni∗)" in Web of Science Core Collection for all available years (1965-2020), all available publications (articles, proceeding papers, reviews) pertaining directly to catatonia were identified, and metadata extracted. Semantic and coauthorship network analyses were conducted. A content analysis was also conducted on all available case reports, case series, and research articles written in English. RESULTS: A total of 1015 articles were identified representing 2861 authors, 346 journals, and 15,639 references. The average number of publications per year over the last 20 years (31.3) more than doubled in comparison to that in the 20 years prior (12.8). The top 3 most common journals were Psychosomatics/Journal of the Academy of Consultation-Liaison Psychiatry, Journal of ECT, and Schizophrenia Research, which represented 12.6% of all publications. Content analysis revealed that catatonia articles are increasingly published in nonpsychiatric journals. There was a notable paucity of clinical trials throughout the study period. Since 2003, articles on catatonia secondary to a general medical condition, as well as articles including child/adolescent patients and patients with autism spectrum disorder or intellectual disability, have made up increasing shares of the literature, with a smaller proportion of articles reporting periodic or recurrent catatonia. We noted a decrease in the proportion of articles detailing animal/in vitro studies, genetic/heredity studies, and clinical trials, along with stagnation in the proportion of neuroimaging studies. CONCLUSIONS: The catatonia literature is growing through contributions from authors and institutions across multiple countries. However, recent growth has largely been driven by increased case reports, with significant downturns observed in both clinical and basic science research articles. A dearth of clinical trials evaluating potential treatments remain a critical gap in the catatonia literature.

Subjective age and its relationships with physical, mental, and cognitive functioning: A cross-sectional study of 1,004 community-dwelling adults across the lifespan.

Perceived younger age is associated with positive health outcomes in existing literature. Few studies have examined these associations using a wide range of variables in large sample of adults of all ages. The objective of present study was to characterize the discrepancy between chronological age (CA) and subjective age (SA) in a large sample of community-dwelling adults across the lifespan, investigate associations with mental, physical, and cognitive health, and examine how it is related to a broad array of psychosocial variables relevant to well-being. Cross-sectional data from 1,004 individuals aged 21-100+ years from the Successful AGing Evaluation (SAGE) study were used for this analysis. Data included self-report measures of physical health (SF-36 - Physical Component), mental health composite score (created using CES-D Happiness scale, Satisfaction with Life Scale, SF-36 Mental Component, Brief Symptom Inventory Anxiety Scale, Patient Health Questionnaire-9, and Perceived Stress Scale), Telephone Interview for Cognitive Status - modified (TICS-m), and validated measures of various positive psychological variables such as meaning in life and optimism. On average, SA was 11.5 years younger than CA (SD 11.3). The discrepancy increased with CA. A younger SA compared to CA was associated with better mental and physical health in all age groups and was positively associated with measures of presence of meaning in life, successful aging, optimism, personal mastery, resilience, curiosity, hope, and social support. The association between age discrepancy and cognitive functioning was not statistically significant. These findings indicate that SA is potentially valuable for the purposes of clinical assessment and intervention, and this possibility should be investigated in future research.

Recent developments in geriatric psychopharmacology.

INTRODUCTION: There is a tremendous growing need to address the burden of geriatric psychiatric disorders. Recent developments relevant to geriatric psychiatry have focused on Alzheimer's disease (AD), severe/refractory depression, and cancer/end of life care. AREAS COVERED: This is a non-systematic, narrative review (databases and websites for search: PubMed, Google Scholar, Medscape, ClinicalTrials.gov; focusing on the last 6 years), and covers developments in disease-modifying therapies for AD, diagnostic radiotracers for AD, medications for neuropsychiatric symptoms of dementia, ketamine/esketamine, psychedelics, and cannabinoids. EXPERT OPINION: The focus of on-going trials of anti-amyloid agents has been on individuals with very early stage AD; several agents are under phase 3 investigation, and aducanumab is under FDA review. Amyloid and tau PET scans have been approved by the FDA to assist in the diagnoses of AD. Promising pharmaceuticals for neuropsychiatric symptoms of dementia include pimavanserin, brexpiprazole, escitalopram, dextromethorphan/quinidine, and lithium. Esketamine, although approved for treatment-resistant depression in general adults, failed to demonstrate efficacy in elderly patients in a phase 3 trial. There is preliminary evidence for benefit of psychedelic-assisted psychotherapy in end-of-life and cancer-related depression/anxiety. Evidence for the use of cannabinoids is currently lacking.

Conceptual and historical evolution of psychiatric nosology.

Psychiatric taxonomies exist within conceptual frameworks which presuppose certain conceptions of psychiatric distress and offer guiding principles. This article provides an overview of the historical development of psychiatric classifications with an emphasis on their methodological assumptions. After identifying roots of scientific psychiatric classifications in the works of Sydenham and Linnaeus and discussing early classification systems, our survey focuses on the Kahlbaum-Hecker-Kraepelin paradigm (with its emphasis on longitudinal course of illness), the Wernicke-Kleist-Leonhard tradition (with its emphasis on neural systems), the development of the ICD and the DSM classifications (with their roots in medical statistics, their pragmatic nature, and their emphasis on descriptive and operationalized criteria), psychodynamic and idiographic perspectives (e.g. the Psychodynamic Diagnostic Manual), and transdiagnostic approaches (e.g. Research Domain Criteria). The central philosophical questions of nosology (descriptive vs aetiological, symptoms vs course of illness, idiographic vs nomothetic, categorical vs dimensional, etc.) have appeared and reappeared throughout this evolution. Ongoing controversies reflect the epistemological and ontological difficulties inherent in defining and classifying mental illness. It may be that no single taxonomy can satisfy all clinical, research, and administrative needs, and that, echoing the ideas of Aubrey Lewis, multiple systems may be required to serve different needs.
