The criteria of the International Headache Society (IHS) define four different primary headache syndromes with daily chronic headaches: chronic migraine, episodic and chronic tension type headache, hemicrania continua, new daily persisting headache. A further important differential diagnosis is medication overuse headache (previously known as analgesia headache). The German, Austrian, and Swiss headache societies now present the first joint guidelines for therapy of these headache syndromes. The current literature was reviewed and a summary is presented. The therapy recommendations do not only include the scientific evidence but also the practical relevance.
