This commentary addresses the use of rimegepant for situational prevention in migraine management. While the approach of using prophylactic treatments during high-risk periods is not new, its application with rimegepant described by Lipton et al. raises ethical and clinical concerns. ⋯ Additionally, the long-term safety of calcitonin gene-related peptide (CGRP) antagonists remains uncertain, especially regarding cardiovascular and other systemic effects. The commentary emphasizes the need for caution and thorough investigation into the long-term risks and benefits of situational prevention with rimegepant before widespread adoption.

A global schools-based programme within the Global Campaign against Headache is estimating the burden of headache in children (6-11 years) and adolescents (12-17 years), cluster-sampling the world by conducting national studies in all world regions. Its purpose is to complement population-based studies in adults, adding to knowledge of the burden of headache and informing educational and health policies. This study in Benin was the third in the programme from sub-Saharan Africa (SSA). ⋯ The finding for migraine is anomalous, but, within this series of studies, the same was found in Zambia and similar in Ethiopia, both in SSA. While many cases identified as probable migraine, especially among children, might better have been diagnosed as UdH, the true prevalence of migraine almost certainly exceeds 21%. Regardless of diagnosis, headache is very common among children and adolescents in Benin. The study sounds an alarm with regard to pMOH as a developing problem pre-adulthood.

Migraine is a neurological disorder characterized by complex, widespread, and sudden attacks with an unclear pathogenesis, particularly in chronic migraine (CM). Specific brain regions, including the insula, amygdala, thalamus, and cingulate, medial prefrontal, and anterior cingulate cortex, are commonly activated by pain stimuli in patients with CM and animal models. This study employs fluorescence microscopy optical sectioning tomography (fMOST) technology and AAV-PHP.eB whole-brain expression to map activation patterns of brain regions in CM mice, thus enhancing the understanding of CM pathogenesis and suggesting potential treatment targets. ⋯ fMOST whole-brain imaging reveals c-Fos + cells in numerous brain regions. OLC improves migraine-like symptoms by modulating brain activity in some brain regions. This study demonstrates the activation of the specific brain areas in NTG-induced CMM and suggests some regions as a potential treatment mechanism according to OLC.

To assess rates of traversing barriers to care to access optimal clinical outcomes in people with migraine internationally. ⋯ Of people with migraine in need of medical care for migraine, less than 15% traverse all 3 barriers to care. Although rates of consultation, diagnosis, and treatment differed among countries, improvements are needed in all countries studied to reduce the global burden of migraine.

We have previously shown headache to be highly prevalent in Cameroon. Here we present the attributed burden. We also perform a headache-care needs assessment. ⋯ Headache disorders in Cameroon are not only prevalent but also associated with high attributed burden, with heavily impaired participation. Headache-care needs are very high, but so are the economic costs of not providing care.
