The ICHD-3 website makes it very easy to understand and follow the precise organisation and content of the current classification, making the practical application in the clinical field and in research simpler than ever before.The three main chapters and the appendix are listed in the main menu.Hopefully many additional translations will be published so that ICHD-3 becomes available in all major and even in many minor languages.An electronic version of ICHD-3 beta already developed under the leadership of Professor Hartmut Göbel has been updated to ICHD-3.My hope is that the active field testing and scientific analysis that have been done for ICHD-3 will continue, allowing future changes to be entirely evidence-based.Following the tradition, it will be 10-15 years before ICHD-4, but a number of field-testing studies will be produced in the meantime.There have been excellent field-testing studies published, in migraine with aura, cluster headache, idiopathic intracranial hypertension and trigeminal neuralgia among others.It was, for example, documented that the Appendix criteria for A1.2 , facial flushing and aural fullness, revealed that they did not add to diagnostic discrimination.
These are examples of the evidence-based process of disease classification that now underpins all future changes to the edition (ICD-11), from the World Health Organization (WHO).
A case book is planned in a collaboration between Professors Morris Levin and Jes Olesen.
Finally, a cross-walk between ICHD-3 and WHO’s ICD-11 will be made by Professors Timothy Steiner and Jes Olesen as soon as the codes for ICD-11 become available.
We have kept this momentum for 30 years, and the superiority of our classification became evident recently during the committee work in Geneva on the neurological section of ICD-11.
No other discipline within neurology has such a systematic classification with explicit diagnostic criteria for every disease entity.
