[New developments in headache management in 2022].

Headaches are one of the most common causes of consultation in primary care. Due to their polymorphic character and sometimes severe etiologies, it is very important to properly classify these symptoms and to look for possible associated signs of severity. It is with this objective that the international classification of headache delivered its 3rd version in 2018 with the ICHD-3. In addition, revised and validated severity criteria were also published in 2018 under the name SNNOOP10. At the same time, the concept of green flags which could allow to diagnose a primary headache without further investigations has emerged. In terms of treatment, the development of CGRP neuropeptide antagonists has allowed a major advance in the treatment of the severe forms of migraine. Finally, integrative medicine is taking on a central role.
