Migraine impacts more than 36 million people in the United States and 1 billion people worldwide. Despite the increasing availability of acute and preventive therapies, there is still tremendous unmet need. Potential treatments in development include monoclonal antibodies (mAbs). Appropriate use of these “biologic” treatments will necessitate an understanding of the aspects that distinguish them from traditional medications. ⋯ The CGRP mAbs are an innovative new therapy for migraine and address the need for effective and tolerable preventive options. MAbs, including those that target CGRP or its receptor, bind to a target with high specificity and affinity and lead to few off-target adverse effects, although mechanism-based adverse reactions may occur. Unlike other therapeutic antibodies used to treat neurologic disease, CGRP mAbs do not have a target within the immune system and have been designed to avoid altering the immune system. The safety and efficacy of mAbs against CGRP or its receptors are being investigated in clinical development programs, and the first of these therapies has received regulatory approval in the United States.

To briefly update and correct the available data on anti-calcitonin gene-related peptide (CGRP) therapies for headache since the American Headache Society 60th Scientific Meeting, San Francisco, June 2018. ⋯ The development of anti-CGRP therapies opens a new era in the acute and preventive treatment of primary headache disorders.

Headache attributed to temporomandibular disorders (TMDH) is defined as a secondary headache by the International Classification of Headache Disorders 3rd edition (ICHD-3).

Most persistent posttraumatic headaches (PPTH) have a phenotype that meets diagnostic criteria for migraine or probable migraine. Although symptoms of autonomic dysfunction have been well described among those with migraine, the presence and relative severity of such symptoms among those with PPTH have yet to be reported. ⋯ Symptoms of autonomic dysfunction were greatest among those with PPTH compared to migraine and healthy controls. Among individuals with PPTH, number of lifetime TBIs was associated with greater symptoms of autonomic dysfunction, while greater headache burden was associated with higher vasomotor domain autonomic dysfunction subscores, potentially indicating that PPTH patients with higher disease burden have an increased risk for having autonomic dysfunction. Symptoms of autonomic dysfunction should be ascertained during the clinical management of patients with PPTH and might be a characteristic that helps differentiate PPTH from migraine.

Comparative Study
A Qualitative Study On Patients With Chronic Migraine With Medication Overuse Headache: Comparing Frequent And Non-Frequent Relapsers.
It is common clinical experience that, after structured withdrawal, some patients with chronic migraine and medication overuse headache (CM with MOH) are more prone than others to relapse and to be in need of further structured treatments. Our aim was to explore similarities and differences between frequent relapsers (FRs) and non-frequent relapsers (NFRs) by considering their point of view, perceptions, and perspective of their subjective experience with relapse into CM with MOH. ⋯ Our results highlight that some differences between FR and NFR patients with CM and MOH exist. Frequent relapsers among patients with CM and MOH reported some important peculiarities of the lived experience of having chronic migraine; clinicians should recognize these psychosocial aspects such as social relationships, future expectations, the experience of illness, medication management, and how the withdrawal experience is regarded, as they may be associated with frequent relapse into MOH.
