A Notice on Classification, Terminology and Contents Innovations to the Primary Headaches Section of the International Classification of Headache Disorders (ICHD-3 Beta)

Overview

The International Classification of Headache Disorders was developed to unify terminology and diagnostic criteria. The first edition was authored by the International Headache Society in 1988 and its revision was published in 2004. The Czech translation was published in 2005. Current revision was prepared to respond to persisting problems with some types of headache, their classification and features. The other reason was to align the ICHD with the 11th revision of the International Classification of Diseases (ICD). The present revision has been named ICHD-3 beta and its final version is to be accepted following official introduction of the 11th revision of the ICD. It is recommended that, instead of the previous version (ICHD-II), this innovated version is used in neurological clinical practice and research. This article has been written to provide the first overview of the revised classification and to describe the main differences between the previous and the current versions.
