[Correspondence] International Classification of Headache Disorders

The third edition of the International Classification of Headache Disorders (ICHD-3) has now been published.1 This classification and the corresponding diagnostic criteria were initially released as a beta document in 2014; since then, they have been widely accepted and should now form the basis of all diagnosis and management of headache disorders in clinical practice as well as in research. The ICHD-3, like its predecessors, is hierarchical and allows diagnosis in different clinical settings, diagnosing at the first or second level in general practice and at the third, fourth, or fifth level in neurological practice or in headache centres.
