There is a fundamental difference between nosology and a statistical classification, and the two should not be confused. The discipline of nosology uses scientific methods to arrive at a classification of psychiatric disorders and is concerned with the validity of its entities. A statistical classification aims to attain the widest compliance in spite of differences in the theoretical orientation of its users. It must therefore be atheoretical, and must represent a widely negotiated agreement between its future users. The most important statistical classification is the “International Classification of Diseases, Injuries and Causes of Death” (ICD-9) endorsed by the member states of the World Health Organization. The DSM III (Diagnostic and Statistical Manual), a newly accepted classification of the American Psychiatric Association, departs in many ways from the ICD-9, and Canada will have to decide whether adherence to ICD-9 should continue, or be replaced by the adoption of DSM III. Advantages and disadvantages of the DSM III are briefly discussed.

The conceptualization of excessive sexual behavior has been intensely debated over the years, and the concept of hypersexuality is still controversial. After long debates, the indexation in ICD-11 (International Classification of Diseases, 11th Revision, World Health Organization, 2018) of excessive and problematic sexual behavior as a compulsive sexual behavior disorder (CSBD) is welcome. There are still debates about the category of the disorder. In ICD-11, CSBD is classified as an impulse control disorder, but this classification is controversial, as there is evidence that CSBD has many addictive features (Kraus et al., 2016). Although the diagnosis of hypersexual disorder, proposed by Kafka, was not included in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th edition, American Psychiatric Association, 2013), this diagnosis was supported by both clinical contexts as well as by some research that indicates that excessive sexual behavior can have serious consequences in an individual’s life (Kafka, 2010; Kaplan & Krueger, 2010, Reid et al., 2012). Understanding, defining and correctly diagnosing this disorder are important prerequisites for proper treatment, and allow also warning of certain risk factors for the development of this disorder.

The psychiatric section, entitled ‘Mental, Behavioural and Developmental Disorders‘ of the International Classification of Diseases, is currently in the process of revision, and ‘ICD—10‘ will shortly become available. This revision will be based partly on its immediate predecessor, the 9th Revision of the International Classification of Diseases (ICD—9; World Health Organization, 1978), and also upon the American Diagnostic and Statistical Manual (DSM—III—R; American Psychiatric Association, 1987). ICD—10 describes and lists symptoms required for making each specific diagnosis and it also refers to inclusions and exclusions. The symptoms themselves, however, are not defined nor described, and an ill-informed method of evaluating symptoms or a lack of thoroughness in their ascertainment will result in mistaken diagnoses. The descriptive psychopathologist clearly has a part to play in encouraging accurate usage.

La discapacidad intelectual (DI) o retraso mental tiene una prevalencia del 2-3% en la población general y se define como una alteración del neurodesarrollo que inicia antes de los 18 años. Se caracteriza por limitación importante en el funcionamiento intelectual y en el comportamiento adaptativo en áreas como comunicación y uso de fuentes para la misma, autocuidado, relaciones sociales o interpersonales, autodirección, funciones académicas, salud y seguridad.1,2 La DI se determina por un coeficiente intelectual (CI) menor de 70 puntos mediante escalas como la International Classification of Diseases (ICD-10), Diagnostic and Statistical Manual of Mental Disorders (DSM V) y la clasificación World Health Organization (WHO).

Abstract The World Health Organization (WHO) is in the process of developing the 11th edition of the International Classification of Diseases (ICD–11). Part of this process includes replacing mental retardation with a more acceptable term to identify the condition. The current international consensus appears to be replacing mental retardation with intellectual disability. This article briefly presents some of the issues involved in changing terminology and the constraints and conventions that are specific to the ICD.

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.

The recent publication of the Diagnostic and Statistical Manual of Mental Disorders 5.1 by the American Psychiatric Association, and the continuing work of the World Health Organization on the 11th revision of the International Classification of Diseases raises once more the question of the need for, the use, and the usefulness of diagnosis in psychiatry The fact that, despite significant advances of science, we are still uncertain about the causes and pathogenesis of mental disorders seems to support the notion that it would be better to use syndromes instead of diagnoses, or go even further and describe mental states in health and disease by a series of ratings on key dimensions of mental functioning. Another option that has also received some backing is the presentation of the universe of mental illness by a series of disease prototypes which, it is argued, would be particularly attractive to practising clinicians. The paper discusses these issues and ends by supporting the use of different ways of presenting mental illness, depending on the purpose of the description.

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.

In 1973 the American Psychiatric Association removed homosexuality from its list of diagnoses, thereby implying that it is a normal variant of sexual behavior. Since then, when homosexuals have sought professional help for emotional problems, psychiatrists have tended increasingly to assist them to believe that their emotional discomfort is the result of society's bias and intolerance and to accept and enjoy their preference for individuals of the same sex. The World Health Organization, however, still includes homosexuality as a medical diagnosis in the International Classification of Diseases. Normally, a child can be expected to develop into an adult with its genetically determined sex. When a boy who is physically and hormonally normal develops a preference for sex with another male, it is an indication that something is amiss. A pathologic family environment is often present in the family of homosexuals. Yet not all boys exposed to a pathologic family during early development become homosexuals. Because of this, the role of disturbed relationships in causing homosexuality is questioned. However, psychoanalyses of male homosexuals have convincingly revealed the existence of a fear of heterosexuality in individuals with genetically predisposed personalities.
