The International Classification of Headache Disorders (ICHD) is a detailed hierarchical classification of all headache-related disorders published by the International Headache Society.[1] It is considered the official classification of headaches by the World Health Organization, and, in 1992, was incorporated into the 10th edition of their International Classification of Diseases (ICD-10).[2] Each class of headache contains explicit diagnostic criteria—meaning that the criteria includes quantities rather than vague terms like several or usually—that are based on clinical and laboratory observations.[2] The ICHD was first published in 1988 (now known as the ICHD-1). The second and current version, the ICHD-2, was published in 2004. | Contents - 1 Hierarchy
