Erenumab is a monoclonal antibody blocking the calcitonin gene-related peptide receptor, which has been approved for the preventive treatment of chronic migraine (CM). The aim of this study was to explore the safety and effectiveness of erenumab in patients suffering from CM and medication overuse headache (MOH) in a real-life setting, up to 1 year.

Learn More >The discovery of calcitonin gene-related peptide (CGRP) and its role in migraine has promoted a new era in migraine treatment: CGRP antagonism. Two classes of medications are currently available: small molecules targeting the CGRP receptor and monoclonal antibodies targeting the CGRP receptor or CGRP ligand. The revolution of these medications is represented by blurring the borders between acute and preventive treatments, episodic and chronic migraine, naïve and refractory patients and even between migraine and other headache disorders.
Learn More >Neuroimaging studies have implicated abnormal brain microstructure in episodic migraine (EM), but whether the pattern is altered during migraine chronification is not well known. Fifty-six patients with migraine without aura, including 39 EM patients and 17 chronic migraine (CM) patients, and 35 healthy controls (HCs) were enrolled. Voxel-based morphometry analysis was performed to assess gray matter (GM) volume differences among groups and their association with clinical feature was examined. Compared with the HC group, both migraine groups showed increased GM volume in the periaqueductal grey matter (PAG) and decreased GM volume in the anterior cingulate cortex (ACC). The left hippocampus/parahippocampal gyrus (PHG) volume of the HC group was smaller than that of the EM group, but was larger than that of the CM group. For the dorsolateral prefrontal cortex (dlPFC), the EM group showed the smallest GM volume while the CM group had the largest volume. Higher headache frequency was associated with greater GM volume in the PAG and dlPFC, but was associated with smaller GM volume in the ACC and hippocampus/PHG across all patients. GM volume changes in regions involved in pain generation and control are potential neural mechanism underlying migraine, and are associated with migraine types and headache frequency.
Learn More >Migraine affects over 40 million Americans and is the world's second most disabling condition. As the majority of medical care for migraine occurs in primary care settings, not in neurology nor headache subspecialty practices, healthcare system interventions should focus on primary care. Though there is grade A evidence for behavioral treatment (e.g., biofeedback, cognitive behavioral therapy (CBT), and relaxation techniques) for migraine, these treatments are underutilized. Behavioral treatments may be a valuable alternative to opioids, which remain widely used for migraine, despite the US opioid epidemic and guidelines that recommend against them. Identifying and removing barriers to the use of headache behavioral therapy could help reduce the disability as well as the personal and social costs of migraine. These techniques will have their greatest impact if offered in primary care settings to the lower socioeconomic status groups at greatest risk for migraine. We review the societal and cultural challenges that impose barriers to optimal use of non-pharmacological treatment services. These barriers include insufficient knowledge of migraine/headache behavioral treatments and insufficient availability of clinicians trained in non-pharmacological treatment delivery; limited access in underserved communities; financial burden; and stigma associated with both headache and mental health diagnoses and treatment. For each barrier, we discuss potential approaches to minimizing its effect and thus enhancing non-pharmacological treatment utilization.Case ExampleA 25-year-old graduate student with a prior history of headaches in college is attending school in the evenings while working a full-time job. Now, his headaches have significant nausea and photophobia. They are twice weekly and are disabling enough that he is unable to complete homework assignments. He does not understand why the headaches occur on Saturdays when he pushes through all week to get through his examinations that take place on Friday evenings. He tried two different migraine preventive medications, but neither led to the 50% reduction in headache days his doctor had hoped for. His doctor had suggested cognitive behavioral therapy (CBT) before initiating the medications, but he had been too busy to attend the appointments, and the challenges in finding an in-network provider proved difficult. Now with the worsening headaches, he opted for the CBT and by the fifth week had already noted improvements in his headache frequency and intensity.
Learn More >Argentina has one of the largest territories in the world, which spreads over a lengthy latitudinal span. Its population is mainly composed of a mixture of South American natives and the descendants of numerous waves of European immigrants. Results from a previous study suggested that the prevalence of migraine in Argentina is the lowest in the region. Here we aimed to reassess the prevalence of migraine in Argentina applying a more sensitive and specific screening tool.
