CONy 2023 | Medication-overuse headache: classification & diagnosis

Medication-overuse headache (MOH) has increasingly become a focus within the headache field. Licia Grazzi, MD, Fondazione IRRCS Istituto Neurologico Carlo Besta, Milan, Italy, discusses the main problems regarding the diagnosis, classification, and clinical aspects of MOH. MOH is classified as a secondary chronic headache, but whether MOH is a primary or secondary headache is still under debate. From a clinical point of view, MOH can be considered an evolution of chronic migraine since MOH doesn’t develop in non-migraine patients. For the most part, patients with frequent headaches eventually overuse their medications. If it happens, diagnosing chronic migraine with medication overuse headache is clinically important because patients rarely respond to preventive medications while overusing acute medications. This interview took place at the 17th World Congress on Controversies in Neurology (CONy) in Dubrovnik, Croatia.
