Headache represents one of the most common symptoms in the emergency department. A systematic approach to headache classification is essential for diagnosis and efficient therapeutic management. New International Headache Classification (ICHD-3 beta) criteria provide a dynamic clinically useful instrument, establishing both uniform terminology and consistent operational diagnostic criteria for a broad range of headache disorders. This article reviews and highlights developments in our knowledge of “Other Primary Headaches”, including primary stabbing headache, primary cough headache, primary exercise headache, primary headache associated with sexual activity, hypnic headache, primary thunderclap headache, cold-stimulus headache, nummular headache, external-pressure headache and new daily persistent headache. Clinicians should be aware that these headaches may be symptomatic to structural lesions and therefore require careful neuroimaging and laboratory evaluation.
