‘Classification’ introduces concepts of mental illness before briefly reviewing the reasons for, and criticisms of, psychiatric classification. Key issues of reliability, validity, and stigma associated with classification are covered. After an overview of the history of classifications, the organizing principles of the two current major classification systems used in psychiatry (ICD-10 and DSM-5) are then outlined: the World Health Organization’s International Classification of Diseases (‘ICD-10’), and the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (‘DSM-5’). Additional schemes, used in particular countries, are also briefly mentioned. Finally, the chapter summarizes how psychiatric classification may develop in the future, with particular reference to ICD-11, which is due in 2018 or 2019.

Obsessive-compulsive disorder (OCD) has been recognized as mainly characterized by compulsivity rather than anxiety and, therefore, was removed from the anxiety disorders chapter and given its own in both the American Psychiatric Association (APA)Diagnostic and Statistical Manual of Mental Disorders(DSM-5) and the Beta Draft Version of the 11th revision of the World Health Organization (WHO)International Classification of Diseases(ICD-11). This revised clustering is based on increasing evidence of common affected neurocircuits between disorders, differently from previous classification systems based on interrater agreement. In this article, we focus on the classification of obsessive-compulsive and related disorders (OCRDs), examining the differences in approach adopted by these 2 nosological systems, with particular attention to the proposed changes in the forthcoming ICD-11. At this stage, notable differences in the ICD classification are emerging from the previous revision, apparently converging toward a reformulation of OCRDs that is closer to the DSM-5.

SummaryBorderline intellectual functioning is an important and frequently unrecognised comorbid condition relevant to the diagnosis and treatment of any and all psychiatric disorders. In the DSM-IV-TR, it is defined by IQ in the 71–84 range. In DSM–5, IQ boundaries are no longer part of the classification, leaving the concept without a clear definition. This modification is one of the least highlighted changes in DSM–5. In this article we describe the history of the classification of borderline intellectual functioning. We provide information about it and on the importance of placing it in the right context and in the right place in future DSM editions and other classification systems such as the International Classification of Diseases.

Zusammenfassung. Hintergrund: Nach 12 Jahren Entwicklung wird die 11. Version der International Classification of Diseases (ICD-11) von der Weltgesundheitsorganisation (WHO) im Januar 2022 in Kraft treten. Methodik: Im Rahmen eines selektiven Übersichtsartikels werden die Veränderungen im Hinblick auf die Klassifikation von Angststörungen von der ICD-10 zur ICD-11 zusammenfassend dargestellt. Ergebnis: Die diagnostischen Kriterien der generalisierten Angststörung, Agoraphobie und spezifischen Phobien werden angepasst. Die ICD-11 wird auf Basis einer Lebenszeitachse neu organisiert, sodass die kindesaltersspezifischen Kategorien der ICD-10 aufgelöst werden. Die Trennungsangststörung und der selektive Mutismus werden damit den „regulären“ Angststörungen zugeordnet und können zukünftig auch im Erwachsenenalter diagnostiziert werden. Neu ist ebenso, dass verschiedene Symptomdimensionen der Angst ohne kategoriale Diagnose verschlüsselt werden können. Diskussion: Die Veränderungen im Bereich der Angsterkrankungen umfassen verschiedene Aspekte und sind in der Gesamtschau nicht unerheblich. Positiv zu bewerten ist die Einführung einer Lebenszeitachse und Parallelisierung mit dem Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Schlussfolgerungen: Die entwicklungsbezogene Neuorganisation in der ICD-11 wird auch eine verstärkte längsschnittliche Betrachtung von Angststörungen in der Klinik sowie Forschung zur Folge haben. Damit rückt insbesondere die Präventionsforschung weiter in den Fokus.

Abstract Background The new International Classification of Diseases—11th revision (ICD-11) succeeds ICD-10. In the three decades since ICD-10 was released, demands for detailed information on the clinical history of a morbid patient have increased. Methods ICD-11 has now implemented an addendum chapter X called “Extension Codes”. This chapter contains numerous codes containing information on concepts including disease stage, severity, histopathology, medicaments, and anatomical details. When linked to a stem code representing a clinical state, the extension codes add significant detail and allow for multidimensional coding. Results This paper discusses the purposes and uses of extension codes and presents three examples of how extension codes can be used in coding clinical detail. Conclusion ICD-11 with its extension codes implemented has the potential to improve precision and evidence based health care worldwide.

A classification system can benefit disturbed children enormously by bringing to bear a wealth of knowledge and experience. This can make all the difference between an inadequate consultation and a precise formulation of the nature and extent of a child's difficulties, their cause, the likely outcome and a realistic treatment plan. However, inappropriate application of a diagnostic label that has little validity could do more harm than good, and classification systems can be misused. This paper discusses, with examples, issues particular to childhood and adolescence that diagnostic systems need to address if they are to be useful. It considers different solutions applied by the two most widely used schemes, the International Classification of Diseases (ICD–10; World Heath Organization, 1992) and the Diagnostic and Statistical Manual of Mental Disorders (DSM–IV; American Psychiatric Association, 1994). Finally, the types of criteria used to validate categories are discussed.

Twenty years have passed from the International Classification of Diseases, Tenth Revision (ICD-10) to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) and, in the meanwhile, a lot of research data about eating disorders has been published. This article reviews the main modifications to the classification of eating disorders reported in the “Feeding and Eating Disorders” chapter of the DSM-5, and compares them with the ICD-10 diagnostic guidelines. Particularly, we will show that DSM-5 criteria widened the diagnoses of anorexia and bulimia nervosa to less severe forms (so decreasing the frequency of Eating Disorders, Not Otherwise Specified (EDNOS) diagnoses), introduced the new category of Binge Eating Disorder, and incorporated several feeding disorders that were first diagnosed in infancy, childhood, or adolescence. On the whole, the DSM-5 revision should allow the clinician to make more reliable and timely diagnoses for eating disorders.

This paper gives a brief outline of the present state of development of the psychiatric chapter of the tenth revision of the International Classification of Diseases (ICD-10). It is written from the point of view of one of the many consultants to the Division of Mental Health, World Health Organization (WHO), Geneva, and thus is not an authoritative or official statement on behalf of WHO. The responsibility for decisions about ICD-10 Chapter V (F) rests with Dr Norman Sartorius, Director of the Division of Mental Health, though many psychiatrists in many countries have contributed to ICD-10 Chapter V (F), and will continue to do so, since much work is still to be done before the final form is officially agreed and published in about 1990. Before he left WHO, Geneva in September, 1986, Dr Assen Jablensky also carried a great deal of responsibility for the arrangements necessary for the production of the drafts of ICD-10 Chapter V (F) that are now being developed.

The International classification of diseases - which includes a chapter dealing with mental disorders - will be revised and its 11th Revision will be published in 2014.A special unit within the World Health Organization coordinates the process of revision and the numerous tasks that have to be undertaken to ensure full participation of the WHO member states in the process of revision as well as the consideration of evidence on which the classification is to be based.The Department of Mental Health and Substance Abuse Control of the WHO has created a special advisory group that should help it in considering the evidence and proposals made by scientists, governments, organizations and interested individuals and in producing the draft of the classification of mental disorders for inclusion into the 11th Revision of the ICD: This group has, in turn, developed several structures that will deal with the tasks that will arise in the revision process. At the same time the American Psychiatric Association has created a DSM 5 Task Force that should develop proposals for the 5th Revision of the Diagnostic and Statistical Manual that will be published in 2012.The lecture will describe the processes and structures that have been put in place by the two organizations and refer to the issues that have arisen or are likely to arise in the course of work that should lead to the proposals for the ICD 11 and the DSM 5.

Mental health conditions in the World Health Organization (WHO) European Region affect more than 10% of the population, with 140,000 lives lost annually to suicide. Comorbidity with other diseases is high. However, basic mental health care is received by less than a third of patients. The COVID-19 pandemic has revealed the vulnerability of mental health services to disruptions and underscored the need to integrate mental health into response strategies. One of the flagship initiatives of the WHO European Programme of Work (EPW), 20202025: United Action for Better Health in Europe is the establishment of a Mental Health Coalition at the European level. In this framework, reporting of health statistics using the International Classification of Diseases 11th Revision (ICD-11) will begin on 1st January 2022. Clinical utility, scientific rigour and wider cultural applicability were all of prime importance in the development of the ICD-11. The 11th Revision was the end product of the most extensive global, multilingual, multidisciplinary and participative process ever undertaken for this task, involving more than 15,000 experts from 155 countries, representing approximately 80% of the worlds population. With the adoption of the ICD-11 and the priority being given to mental health, new ideas based on the 30 years of research since the approval of the ICD-10 will be widely adopted and applied.
