The Work Accidents and Occupational Diseases Act exists in Chile since 1968. It uses a single model for the understanding and management of both somatic diseases like silicosis and psychiatric disorders. During the last decade in Chile, the consultation rates due to psychiatric conditions of probable labor origin has rose over 1,000%, a factor that underscored the deficiencies of this model. The aim of this paper is to analyze the consequences of the application of this act in the psychiatric field for almost 50 years after its promulgation...

Progress in understanding the underlying neurobiology of obsessive-compulsive disorder (OCD) has stalled in part because of the considerable problem of heterogeneity within this diagnostic category, and homogeneity across other putatively discrete, diagnostic categories. As psychiatry begins to recognize the shortcomings of a purely symptom-based psychiatric nosology, new data-driven approaches have begun to be utilized with the goal of solving these problems: specifically, identifying trans-diagnostic aspects of clinical phenomenology based on their association with neurobiological processes...

Hypersexuality refers to abnormally increased or extreme involvement in any sexual activity. It is clinically challenging, presents trans-diagnostically and there is extensive medical literature addressing nosology, pathogenesis and neuropsychiatric aspects. Classification includes deviant behaviours, diagnosable entities related to impulsivity, and obsessional phenomena. Some clinicians view an increase in sexual desire as 'normal' while psychodynamic theorists consider it ego-defensive at times alleviating unconscious anxiety rooted in intrapsychic conflicts...

The Global Mental Health (GMH) movement has raised questions of the translatability of psychiatric concepts and the challenges of community engagement. In Tonga, the local psychiatrist Dr Puloka successfully established a publicly accessible psychiatry that has improved admission rates for serious mental illnesses and addressed some of the stigma attached to diagnosis. On the basis of historical analysis and ethnographic fieldwork with healers, doctors, and patients since 1998, this article offers an ethnographic contextualization of the development and reception of Puloka's three key interventions during the 1990s: (a) collaboration with traditional healers; (b) translation of psychiatric diagnoses into local cultural concepts; and (c) encouraging freedom of movement and legal appeal to involuntary admission...

Emil Kraepelin (1856-1926) is considered one of the founders of modern psychiatric nosology. However, his conceptualization of obsessive-compulsive phenomena is relatively understudied. In this article, we compare and contrast excerpts from the eighth edition (1909-1915) of Kraepelin's Textbook of Clinical Psychiatry focusing on what Kraepelin called "obsessive neurosis" and related "original pathological conditions" with the current DSM-5 criteria for obsessive-compulsive disorder (OCD). Consistently with DSM-5 OCD, Kraepelin described obsessive neurosis as characterized by obsessive ideas, compulsive acts, or both together...

The Kraepelinian syndromal approach to diagnosis taken by DSM-III and its successors, which defines disorders by their clinical phenomenon, has come under rising criticism with increasing calls for an etiologically based nosology. The relative virtues of a syndromal versus etiologic psychiatric nosology have actually been debated within our field for a long time. To deepen and historically contextualize our current discussion, I review in detail the proposal for etiologic diagnostic systems for insanity by David Skae (1814-1873)...

We review the concept of endophenotype, and its relationship with related terms in use in the scientific literature, including "biomarker" and "intermediate phenotype". We then explain the importance of the concept in current psychiatry research. Specifically, we focus in the potential importance of endophenotypes in both disentangling the genetic causes, and improving the dimensional and pathophysiologic definition, of psychiatric nosological categories. After delineating which types of variables could constitute valid endophenotypes, we describe efforts in defining neurobiological signatures of social cognitive deficits in schizophrenia as an example with potential heuristic value...

The criteria for posttraumatic stress disorder PTSD have changed considerably with the newest edition of the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Changes to the diagnostic criteria from the DSM-IV to DSM-5 include: the relocation of PTSD from the anxiety disorders category to a new diagnostic category named "Trauma and Stressor-related Disorders", the elimination of the subjective component to the definition of trauma, the explication and tightening of the definitions of trauma and exposure to it, the increase and rearrangement of the symptoms criteria, and changes in additional criteria and specifiers...

BACKGROUND: Prolonged grief disorder (PGD) is a bereavement-specific syndrome expected to be included in the forthcoming ICD-11. Defining the prevalence of PGD will have important nosological, clinical, and therapeutic implications. The present systematic review and meta-analysis aimed to estimate the prevalence rate of PGD in the adult bereaved population, identify possible moderators, and explore methodological quality of studies in this area. METHODS: A systematic literature search was conducted in PubMed, PsycINFO, Embase, Web of Science, and CINAHL...

Hypersomnolence plays an important role in the presentation, treatment and course of mood disorders. However, there has been relatively little research that examines objective measures of sleep duration and continuity in patients with depression and hypersomnolence, despite the use of these factors in sleep medicine nosological systems. This study compared total sleep time and efficiency measured by naturalistic actigraphic recordings followed by ad libitum polysomnography (PSG; without prescribed wake time) in 22 patients with major depressive disorder and co-occurring hypersomnolence against age- and sex-matched healthy sleeper controls...

BACKGROUND: Stratified or personalised medicine targets treatments for groups of individuals with a disorder based on individual heterogeneity and shared factors that influence the likelihood of response. Psychiatry has traditionally defined diagnoses by constellations of co-occurring signs and symptoms that are assigned a categorical label (e.g. schizophrenia). Trial methodology in psychiatry has evaluated interventions targeted at these categorical entities, with diagnoses being equated to disorders...

BACKGROUND: Mild behavioral impairment (MBI) is a construct that describes the emergence at ≥50 years of age of sustained and impactful neuropsychiatric symptoms (NPS), as a precursor to cognitive decline and dementia. MBI describes NPS of any severity, which are not captured by traditional psychiatric nosology, persist for at least 6 months, and occur in advance of or in concert with mild cognitive impairment. While the detection and description of MBI has been operationalized in the International Society to Advance Alzheimer's Research and Treatment - Alzheimer's Association (ISTAART-AA) research diagnostic criteria, there is no instrument that accurately reflects MBI as described...

Mixed features specifier (MFS) is a new nosological entity defined and operationalized in the Diagnostic and Statistical Manual of Mental Disorders (DSM), 5th Edition. The impetus to introduce the MFS and supplant mixed states was protean, including the lack of ecological validity, high rates of misdiagnosis, and guideline discordant treatment for mixed states. Mixed features specifier identifies a phenotype in psychiatry with greater illness burden, as evidenced by earlier age at onset, higher episode frequency and chronicity, psychiatric and medical comorbidity, suicidality, and suboptimal response to conventional antidepressants...

The reliability and validity of psychiatric diagnoses have always been a major concern. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) reliability field trials yielded ambiguous results, with some diagnostic categories scoring well below par. We argue that the emphasis on the reliability of psychiatric diagnoses, which has dominated psychiatric nosology and guided the endeavor of improving the DSM in its consecutive editions, is misguided and lacks in structural validity. In this article, we defend a pragmatic view on psychiatric disease as the most fruitful approach to an understanding of what the categorical distinctions in the DSM (can) represent...

Psychiatry research has long experienced a stagnation stemming from a lack of understanding of the neurobiological underpinnings of phenomenologically defined mental disorders. Recently, the application of computational neuroscience to psychiatry research has shown great promise in establishing a link between phenomenological and pathophysiological aspects of mental disorders, thereby recasting current nosology in more biologically meaningful dimensions. In this review, we highlight recent investigations into computational neuroscience that have undertaken either theory- or data-driven approaches to quantitatively delineate the mechanisms of mental disorders...

BACKGROUND: Despite growing consensus on nosology and epidemiology of bipolar disorder (BD) in minors, differences remain. We contribute to this discussion by measuring long-term trends in the inpatient discharge rates of BD in minors. METHODS: Nationwide German inpatient discharge diagnoses of BD and other related psychiatric disorders were mapped between 2008 and 2013 using registry data from the German Federal Health Monitoring System. This was compared with previously published data, 2000-2007, to assess long-term trends in diagnosis of BD at discharge...

BACKGROUND: 'Acute and transient psychotic disorder' (ATPD) is a category in ICD-10 marked by psychosis with acute onset and early remission. It remains relatively under-researched, despite controversies over its nosological status in the current classification system. AIMS: (1) To assess the changes in diagnosis over time in patients initially diagnosed as ATPD. (2) To identify factors predicting changes in diagnosis, and compare the long-term outcomes of various patterns of diagnostic shift...

For decades, the nosology of mental illness has been based largely upon the descriptions in the Diagnostic and Statistical Manual of the American Psychiatric Association (DSM). A recent challenge to the DSM approach to psychiatric nosology from the National Institute on Mental Health (USA) defines Research Domain Criteria (RDoC) as an alternative. For RDoC, psychiatric illnesses are not defined as discrete categories, but instead as specific behavioral dysfunctions irrespective of DSM diagnostic categories...

Traditionally, psychopathology has been conceptualized in terms of polythetic categories derived from committee deliberations and enshrined in authoritative psychiatric nosologies-most notably the Diagnostic and Statistical Manual of Mental Disorders (DSM; American Psychiatric Association [APA], 2013). As the limitations of this form of classification have become evident, empirical data have been increasingly relied upon to investigate the structure of psychopathology. These efforts have borne fruit in terms of an increasingly consistent set of psychopathological constructs closely connected with similar personality constructs...

BACKGROUND: The diagnostic scheme for psychiatric disorders is currently based purely on descriptive nomenclature given that biomarkers subtypes and clearly defined causal mechanisms are lacking for the vast majority of disorders. The emerging field of "immuno-psychiatry" has the potential to widen the exploration of a mechanism-based nosology, possibly leading to the discovery of more effective personalised treatment strategies. DISCUSSION: Disturbances in immuno-inflammatory and related systems have been implicated in the aetiology, pathophysiology, phenomenology and comorbidity of several psychiatric disorders, including major mood disorders and schizophrenia...
