New Daily Persistent Headache: a Diagnostic and Therapeutic Odyssey

Purpose of ReviewNew daily persistent headache (NDPH) is a rare primary headache disorder, which often has a refractory clinical course. This narrative review seeks to highlight what is known about the development of NDPH, to outline a diagnostic approach to a patient with new daily headache, and to explore management considerations and potential future therapies for patients diagnosed with NDPH.Recent FindingsInterval work at the level of case series and cohort studies has identified novel triggering factors (e.g., Valsalva), subgroups with unique temporal profiles (e.g., thunderclap onset), psychophysical profiles (e.g., increased pain catastrophizing), and potential treatment options.SummaryThe approach to the diagnosis and treatment of NDPH remains individualized, driven by clinical features and challenging in most cases. Earlier identification of patients (e.g., prediction of patients with status migrainosus destined to develop NDPH) may allow for more effective treatment.
