Migraine is a highly prevalent and complex neurovascular disease. However, the currently available therapeutic drugs often fall to adequately meet clinical needs due to limited effectiveness and numerous undesirable side effects. This study aims to identify putative novel targets for migraine treatment through proteome-wide Mendelian randomization (MR). ⋯ A set of potential protein targets for migraine and its subtypes were identified. These proteins showed rare side effects and were responsible for biological mechanisms involved in migraine pathogenesis, indicating priority for the development of migraine treatments.

Having previously shown headache disorders to be prevalent in Mongolia, here we elaborate on headache as a public-health concern in this country, reporting symptom burden and headache-attributed impaired participation at individual and societal levels, and conducting a health-care needs assessment. ⋯ This first population-based study on headache burden in Mongolia shows high levels of individual and societal burden, with H15 + the cause of greater burden at population level than migraine and TTH combined. Migraine, however, has the biggest impact on the nation's productivity. From a purely economic perspective, Mongolia, with limited health resources, would probably be best served by focusing on mitigating migraine-attributed burden.

Observational Study
Therapeutic effect of a single lumbar puncture in idiopathic intracranial hypertension.
Idiopathic intracranial hypertension (IIH) is a neurological disorder characterized by increased intracranial pressure. Whilst lumbar puncture (LP) is necessary for the diagnosis of IIH, its therapeutic effect remains unclear. Our aim was to evaluate the therapeutic effect of a single LP in people with IIH (pwIIH). ⋯ This short-term follow-up study in pwIIH undergoing a single LP suggests a moderate effect on ophthalmological but not headache outcomes. The usefulness of LP as a therapeutic measure in IIH remains controversial and should likely be reserved for patients with limited treatment options, e.g., in pregnancy or intolerability to medication.

About a quarter of migraine cases among women have menstrual migraine (MM), which is usually more severe, longer lasting, and less responsive to treatment than typical migraine. Randomized controlled trials (RCTs) have evaluated the efficacy of several medication in the acute and preventive treatment of MM; this meta-analysis compared the effectiveness of these treatments. ⋯ Sumatriptan and lasmiditan are effective first-line treatments for acute MM. For prevention, frovatriptan may be the more effective of triptans. Compared with triptans, CGRP monoclonal antibodies, here including erenumab and galcanezumab, are more effective in reducing headache days, and therefore, in preventing MM.

Multicenter Study
Idiopathic intracranial hypertension in Asians: a retrospective dual-center study.
There have been limited data on idiopathic intracranial hypertension (IIH) in Asians and there remain uncertainties whether a cerebrospinal fluid (CSF) pressure of 250 mm CSF is an optimum diagnostic cutoff. The aims of the present study included (1) characterization of IIH patients in Taiwan, (2) comparisons among different diagnostic criteria for IIH, and (3) comparisons between patients with CSF pressures of > 250 and 200-250 mm CSF. ⋯ It was found that obesity and papilledema were less common in Asian IIH patients when compared with Caucasian patients. Although patients with CSF pressures of 200-250 mm CSF had a less severe phenotype, the risks of having headache or visual loss were comparable to those in the > 250 mm CSF group. It is possible that a diagnostic cutoff of > 200 mm CSF could be more suitable for Asians, although further studies are still needed.
