Headache

OBJECTIVE: To determine if there are changes in structure and function of the retinal vasculature during and between migraine attacks using optical coherence tomography angiography (OCTA). BACKGROUND: Migraine attacks commonly include visual symptoms, but the potential role of the retina in these symptoms is not well understood. OCTA is a rapid, non-invasive imaging technique that is used to visualize the retinal microvasculature with high spatial resolution in a clinical setting...

BACKGROUND: We evaluated galcanezumab for migraine prevention in patients who met International Classification of Headache Disorders, 3rd edition criteria for menstrually related migraine (MRM). METHODS: Patients were identified post hoc from three double-blind, randomized, phase 3 clinical trials in patients with episodic migraine. Patients completed a 1-month prospective baseline period and up to 6 months (EVOLVE-1 and -2, studies pooled) of double-blind treatment with galcanezumab (120 mg/month) or placebo...

OBJECTIVE: To examine trends in diagnosis of headache and migraine in a large pediatric neurology cohort, and test whether an electronic health record (EHR)-integrated headache questionnaire can increase specificity of diagnosis and likelihood of prescribing migraine treatment. BACKGROUND: Under-diagnosis of migraine contributes to the burden of disease. As we founded our Pediatric Headache Program in 2013, we recognized that the proportion of patients with headache who were given a diagnosis of migraine was much lower than expected...

OBJECTIVE: This study aimed to determine the number needed to treat (NNT), number needed to harm (NNH), and likelihood of being helped or harmed (LHH) in a post hoc analysis of the phase 3b FOCUS trial. BACKGROUND: Fremanezumab, a humanized monoclonal antibody that selectively targets calcitonin gene-related peptide (CGRP), has demonstrated efficacy, tolerability, and safety in adults with episodic migraine (EM) or chronic migraine (CM), with documented previous inadequate response to two to four classes of migraine preventive medications...

OBJECTIVE: The study aimed to examine the relationship between secondhand smoke (SHS) exposure and severe headaches or migraine in never-smoking adults verified by serum cotinine. BACKGROUND: Current evidence about the association between self-reported SHS exposure and headaches or migraine is limited and contradictory. An important issue lies in the lack of actual SHS exposure assessment through biomarkers. METHODS: We conducted a cross-sectional study on 4560 never-smoking adults from the National Health and Nutrition Examination Survey (NHANES), 1999-2004...

OBJECTIVE: To determine the effect of the introduction of the calcitonin gene-related peptide monoclonal antibodies (CGRP mAbs) in 2018 on the prescribing of older medications for the prevention of chronic migraine. BACKGROUND: Prior to 2018, the preventive treatment of migraine borrowed from medications intended to treat other illnesses with the last medication, onabotulinumtoxinA, receiving Food and Drug Administration (FDA) approval for the prevention of chronic migraine in 2010...

OBJECTIVE: To evaluate an alternative method of defining acute treatment success in migraine by combining multiple indicators into a single dichotomous measure of success. BACKGROUND: Migraine is characterized by a symptom complex; combining these features as a single endpoint may improve the measurement of treatment effects and better predict patient satisfaction with treatment. METHODS: We used a confirmatory latent class model (LCM) with two latent classes interpreted as treatment success and treatment failure...

OBJECTIVE: To describe the pattern of anti-calcitonin gene-related peptide monoclonal antibodies (anti-CGRP mAbs) utilization in the Tuscany region, Italy, and the variation of triptan consumption after treatment initiation. BACKGROUND: Given the recent commercialization of anti-CGRP mAbs as migraine preventive medications, real-world evidence on their patterns of utilization and their impact on migraine abortive medication use is still limited. METHODS: A retrospective, descriptive, cohort study on the real-world utilization of anti-CGRP mAbs was performed using the population-based regional administrative database of Tuscany...

OBJECTIVE: The objective of this study was to characterize the utility of calcitonin gene-related peptide (CGRP) and nerve growth factor (NGF) as potential biomarkers for headache and pain disorders in the post-military deployment setting. BACKGROUND: The need to improve recognition, assessment, and prognoses of individuals with posttraumatic headache or other pain has increased interest in the potential of CGRP and NGF as biomarkers. METHODS: The Warrior Strong Study (NCT01847040) is an observational longitudinal study of United States-based soldiers who had recently returned from deployment to Afghanistan or Iraq from 2009 to 2014...

OBJECTIVE: Caffeine, a non-selective adenosine receptor (AR) antagonist, is the most consumed psychostimulant in the world. Caffeine has been suggested to regulate cerebrospinal fluid secretion and is known both to alleviate and to trigger headache; however, its effect on the regulation of intracranial pressure (ICP) is not known. Therefore, we aimed to investigate the effects of caffeine on ICP and nociceptive responses. METHODS: Female Sprague-Dawley rats were implanted with a novel telemetric device for continuous ICP recordings, which allowed for continuous recordings in freely moving rats...

OBJECTIVE: To systematically synthesize evidence from a broad range of studies on the association between air pollution and migraine. BACKGROUND: Air pollution is a ubiquitous exposure that may trigger migraine attacks. There has been no systematic review of this possible association. METHODS: We searched for empirical studies assessing outdoor air pollution and any quantified migraine outcomes. We included short- and long-term studies with quantified air pollution exposures...
