Des classifications des maladies mentales. Introduction

Physicians in France have for a long time taken an interest in nosography, in the systematic description and naming/classification of mental diseases. Early XIX^thand XX^thcentury nosographies – as soon as he was appointed as professor of medical pathology at the Paris Health School, Philippe Pinel published the first editions of Nosographie philosophique ou méthode de l’analyse appliquée à la médecine (A Philosophical nosography or an analysis method applied to medicine). Numerous editions of this work were published in the early part of the XIXth century and it was considered the reference book in the field of mental diseases classification. It is therefore not surprising to know that, in the XIXth and XXth centuries, several sessions of the Société Médico-Psychologique, which had been founded in 1852, were dedicated to discussing the various classifications proposed by psychiatrists alienists. Several papers on these discussions, published by Thierry Haugsten, are to be found in the Annales Médico-Psychologiques. French classifications of mental diseases at the start of the XXIth century – In recent years, several sessions were devoted to the presentation and discussion of the latest editions of the French Classification of Mental Diseases in Children and Adolescents CFTMEA R 2012 and today we are going to present the French Classification of Mental Diseases CFTM R–2015 which has recently come out.
