Clinical trials for idiopathic intracranial hypertension: what are we treating?
New guidelines for designing controlled clinical trials for idiopathic intracranial hypertension (IIH) have been published. The design of such trials remains a challenge, as the heterogeneity of IIH necessitates different outcome measures for specific clinical presentations.

Zavegepant for the acute treatment of migraine: look before leaping
Results from a phase III trial have set zavegepant as the first intranasal gepant to be approved by the FDA for the acute treatment of migraine. The therapeutic benefits were modest, however, and more work is needed to address unmet treatment needs.

Identifying molecular targets in trigeminal nociception
A new paper published in Neuron presents an analysis of mRNA expression in human and mouse trigeminal ganglia at single-nucleus resolution. The resulting resource is thought-provoking and suggests new targets for pain therapies; however, the findings should be interpreted in the context of the available protein data and warrant functional verification.

Headache in people with epilepsy
Headaches and epilepsy frequently co-exist in the same individual, but the pathophysiological mechanisms underlying this relationship are not yet clear. Here, the authors discuss the epidemiological and pathophysiological links between epilepsy and headache, and apply this knowledge to the clinical management of the two disorders.

Potassium channel openers — novel triggers of aura and migraine
Results of two recent studies by Messoud Ashina and colleagues demonstrate that infusion of two different potassium channel openers can trigger migraine in humans; one of the compounds also triggered aura in patients diagnosed with migraine with aura. The findings highlight the importance of human experimental models in migraine research.

Lessons from lockdown — behavioural interventions in migraine
A recent study reports an improvement in migraine symptoms during a COVID-19 lockdown in the Netherlands. The findings suggest that lifestyle changes can substantially alter the course of migraine, opening the door for greater use of behavioural interventions alongside existing pharmacological therapies.

Making headway — a role for CGRP in post-traumatic headache
Although common, post-traumatic headache remains poorly understood and poorly treated. New data have implicated calcitonin gene-related peptide and the trigeminovascular system in this disorder, opening up new avenues for research into its pathophysiology and treatment.

CGRP-targeted antibodies in difficult-to-treat migraine
A new study shows that the monoclonal antibody fremanezumab is effective for migraine prophylaxis, even in patients who have failed to respond to multiple preventive treatments. However, not all patients benefit from this treatment, and detailed investigation of non-responders could help to identify additional pharmacological targets and increase the number of responders.

The metabolic face of migraine — from pathophysiology to treatment
In this Review, the authors describe the evidence for abnormalities in energy metabolism and mitochondrial function in migraine, consider the potential mechanisms and highlight treatments that affect metabolism. They conclude that migraine is a conserved adaptive response that helps to restore brain energy homeostasis.

Does inflammation have a role in migraine?
Migraine is one of the world’s most prevalent diseases, and approximately 2% of the general population experiences chronic migraine. Edvinsson and colleagues argue that inflammation could have an important role in migraine chronification, through a mechanism termed neurogenic neuroinflammation.

CGRP antibodies for migraine prevention — new kids on the block
In the past few years, a number of new migraine treatments have emerged, including monoclonal antibodies against calcitonin gene-related peptide (CGRP) and the CGRP receptor. Now, a position statement from the American Headache Society offers guidance on the integration of these agents into clinical practice in the prevention of migraine.

Getting closer to a cure for migraine
In the past few years the scientific community has witnessed a prodigious surge in research activity, publication of data and progress in understanding the mechanistic components of migraine. This renaissance is the result of efforts initiated decades ago that are finally being translated into benefits for individuals affected by this disease.

Sleep apnoea and poor sleep quality in patients with chronic migraine
Chronic migraine is a debilitating condition that arises from the worsening of episodic migraine. A large population-based questionnaire study showed that individuals with chronic migraine reported more sleep apnoea and worse sleep quality than individuals with episodic migraine. This finding provides important insights into the association between sleep disturbances and chronic migraine.

Evidence mounts for anti-CGRP treatment in cluster headache
During cluster headache attacks, plasma levels of calcitonin gene-related peptide (CGRP) increase, and trigeminal nerve activation leads to pain. A new study shows that CGRP infusion can induce cluster headache attacks in some patients, with important implications for the investigation of CGRP-targeted therapies in cluster headache.

Cluster headache treatment — RCTs versus real-world evidence
Recently published American Headache Society evidence-based guidelines for cluster headache management provide updated guidance on which therapies are superior to placebo in randomized controlled trials. These valuable recommendations do not always translate to real-world settings, however, and other criteria should be taken into account when attempting to treat cluster headache.

Treasure hunt in a minefield — exploring migraine with GWAS
In a powerful display of international collaboration, a new genome-wide association study has mapped susceptibility loci for migraine on the basis of genetic data from 375,000 individuals. The study implicates several new loci in migraine — many of them suggestive of vascular pathophysiology — but the functional relevance of many now-detected risk alleles remains elusive.

Incredible progress for an era of better migraine care
In the past 10 years, the realization that migraine is a brain disorder rather than a vascular disorder has facilitated development of various treatments, ranging from innovative immunopharmaceuticals through to neurostimulation. Many clinical trials have been successful, and such considerable progress holds promise for the coming decade of migraine treatment.
