Current prophylactic drugs for cluster headache are associated with limited efficacy, serious side effects and poor tolerability. Greater occipital nerve injection (GON-injection) has been proven effective and safe as a single, one-time injection in episodic (ECH), and to a lesser extent, chronic cluster headache (CCH). We aim to analyse the effectiveness and safety of repeated GON-injections in medically intractable chronic cluster headache (MICCH).
Learn More >Lockdown measures due to the COVID-19 pandemic have led to lifestyle changes, which in turn may have an impact on the course of headache disorders. We aimed to assess changes in primary headache characteristics and lifestyle factors during the COVID-19 lockdown in Germany using digital documentation in the mobile application (app) M-sense.
Learn More >Erenumab is a human anti-calcitonin gene-related peptide receptor monoclonal antibody approved for migraine prevention. Global studies have demonstrated its efficacy in chronic and episodic migraine (EM). Here we report the outcomes from a Phase 3 study of erenumab in Japanese patients with chronic migraine (CM) or EM.
Learn More >It is well established that migraine is a multifactorial disorder. A deep understanding of migraine should be based upon both the underlying traits and the current states affected by different physiological, psychological, and environmental factors. At this point, there is no framework fully meeting these criteria. Here, we describe a broader view of the migraine disorder defined as a dysfunctional brain state and trait interaction. In this model, we consider events that may enhance or diminish migraine responsivity based on an individual's trait and state. This could provide an expanded view for considering how migraine attacks are sometimes precipitated by "triggers" and sometimes not, how these factors only lead to migraine attacks in migraine patients, or how individuals with an increased risk for migraine do not show any symptoms at all. Summarizing recent studies and evidence that support the concept of migraine as a brain state-trait interaction can also contribute to improving patient care by highlighting the importance of precision medicine and applying measures that are able to capture how different traits and states work together to determine migraine.
Learn More >: In the absence of head-to-head comparisons, the objective of this study was to conduct a network meta-analysis (NMA) to indirectly compare the relative efficacy and safety of rimegepant, ubrogepant, and lasmiditan for the acute treatment of migraine. : A systematic literature review was conducted to identify randomized controlled trials (RCTs) of rimegepant, ubrogepant and lasmiditan in adults with acute migraine. Outcomes included sustained pain freedom and -relief 2-48 hours post-dose, and adverse events. No RCTs were identified that directly compared these interventions. Therefore, a fixed-effects Bayesian NMA was conducted by identifying a connected (via comparison to placebo) network of RCTs. : Five RCTs were identified: rimegepant study 303 (n=1,466), ubrogepant ACHIEVE I and II (n=1,672 and n=1,686, respectively), and lasmiditan SAMURAI and SPARTAN (n=2,231 and n=3,005, respectively). Efficacy outcomes (pain freedom and relief at 2, 24, 48 hours) tended to be highest for lasmiditan 200 mg and rimegepant followed lower doses of lasmiditan and all doses of ubrogepant. However, lasmiditan 200 mg was also associated with higher rates of adverse events, particularly somnolence and dizziness. : Lasmiditan, rimegepant, and ubrogepant all performed significantly better than placebo with respect to pain freedom and pain relief. Efficacy results were similar for rimegepant and lasmiditan with rimegepant having higher rates of pain freedom and relief than lower doses of lasmiditan, while somnolence and dizziness outcomes were lower for rimegepant than higher doses of lasmiditan.
Learn More >Hypertension and headache disorders are major contributors to public ill health, linked by a long-standing but questionable belief that hypertension is a conspicuous cause of headache. In Nepal, where hypertension is common and often untreated, we assessed the substance of this belief, hypothesising that, should hypertension be a significant cause of headache, a clear positive association between these disorders would exist.
Learn More >Migraine and trigemino-autonomic cephalalgia attacks are associated with an increase of α-calcitonin-gene related peptide levels in the ipsilateral jugular vein. It is however unknown whether trigeminal pain stimulation in healthy subjects without headache disorders also induces increase of calcitonin-gene related peptide levels.
Learn More >To use 1) newly generated data, 2) existing evidence, and 3) expert opinion to create and validate a new cluster headache screening tool.
Learn More >Although the role of glutamate in migraine pathogenesis remains uncertain, there has been significant interest in the development of drug candidates that target glutamate receptors. Activation of trigeminovascular afferent fibers is now recognized as a crucial step to the onset of a migraine episode. New evidence suggests a dysfunction in peripheral glutamate regulation may play a role in this process.
Learn More >The association between diet and migraine has been reported in the literature, but only a few studies have evaluated whether the diet consumed by patients with migraine differs from individuals without migraine.
