Jes Olesen, Chairman ICHD-III β
In June 2013, the International Headache Society (IHS) published the beta version of the 3rd edition of the International Classification of Headache Disorders (ICHD-IIIβ). In recent years, numerous new findings on the diagnosis and classification of headache disorders have been scientifically developed and published. These findings have been incorporated into the new 3rd edition over the past three years. The current 3rd edition has been revised very carefully and conservatively.
While ICHD-I and ICHD-II were published directly, a so-called beta version is being released for the new edition. This is a test version intended to be tested for practical use. The main reason for this beta version is that ICHD-III is to be synchronized with the 11th edition of the WHO classification (ICD-11).
The goal is to achieve direct congruence between the ICD-11 and the ICHD-III. A period of field trials is required for both classification systems. This timeframe allows for the identification of potential errors, the analysis of usability and applicability, and the incorporation of these findings into the final version.
The ICD-11 is not expected to be finalized for another three years. Only then will the internationally valid diagnostic codes be available. These official codes will then also be integrated into the ICHD-III.
The ICHD-III is available for download website of the International Classification of Headache Disorders
Clinicians and researchers should immediately begin using the ICHD-IIIβ criteria. This new headache classification includes numerous improvements and should be used now for both clinical care and research.
