Purpose of Review
Episodic migraine is common. Everyday behavioral patterns are associated with migraine attacks and disability. This paper reviews health behaviors that can be targeted in people with episodic migraine to enhance migraine-related outcomes.Recent Findings
Stressful events and perceived stress have demonstrated associations with migraine attack onset among people with episodic migraine. Consistency in daily patterns (eating, sleeping, exercise, and hydration status) is also associated with migraine activity. Sleep deprivation, fatigue, and poor quality sleep have demonstrated relationships with migraine attack onset, as well as headache frequency and headache-related disability in people with episodic migraine.Summary
The health behaviors implicated in episodic migraine are part of everyday patterns and can be targeted routinely in clinical practice to improve migraine management. Behavior change is challenging and should ideally be supported by a multidisciplinary team. Future research should focus on evaluating specific behavior change interventions and the relative impact of behavior on migraine outcomes in high- and low-frequency episodic migraine.2.
Purpose of Review
This review evaluates and explains our current understanding of a rare subtype of migraine, typical aura without headache, also known as migraine aura without headache or acephalgic migraine.Recent Findings
Typical aura without headache is a known entity within the spectrum of migraine. Its pathophysiology is suggested to be similar to classic migraines, with cortical spreading depression leading to aura formation but without an associated headache. No clinical trials have been performed to evaluate treatment options, but case reports suggest that most patients will respond to the traditional treatments for migraine with aura. Bilateral greater occipital nerve blocks may be helpful in aborting migraine with prolonged aura. Transcranial magnetic stimulation has shown efficacy in aborting attacks of migraine with aura but has not been specifically tested in isolated aura.Summary
Typical aura without headache occurs exclusively in 4% patients with migraine, and may take place at some point in 38% of patients with migraine with aura. Typical aura without headache commonly presents with visual aura without headache, brainstem aura without headache, and can also develop later in life, known as late-onset migraine accompaniment.3.

Purpose of Review
In contrast to well-established relationships between headache and affective disorders, the role of alcohol use in primary headache disorders is less clear. This paper provides a narrative overview of research on alcohol use disorders (AUDs) in primary headache and presents a meta-analysis of the role of alcohol as a trigger (precipitant) of headache.Recent Findings
The majority of studies on AUDs in headache have failed to find evidence that migraine or tension-type headache (TTH) is associated with increased risk for AUDs or problematic alcohol use. The meta-analysis indicated that 22% (95% CI: 17–29%) of individuals with primary headache endorsed alcohol as a trigger. No differences were found between individuals with migraine (with or without aura) or TTH. Odds of endorsing red wine as a trigger were over 3 times greater than odds of endorsing beer.Summary
An absence of increased risk for AUDs among those with primary headache may be attributable to alcohol’s role in precipitating headache attacks for some susceptible individuals. Roughly one fifth of headache sufferers believe alcohol precipitates at least some of their attacks. Considerable study heterogeneity limits fine-grained comparisons across studies and suggests needs for more standardized methods for studying alcohol-headache relationships and rigorous experimental designs.4.

Purpose of Review
This review synthesizes the utility of measuring migraine triggers for the purpose of forecasting future headache attacks. The nature of forecasting models, headache triggers as inputs to such models, and how these trigger exposures can be measured for forecasting are reviewed. A critical evaluation of the existing forecasting models in the context of their potential application for preemptive treatment is considered.Recent Findings
A substantial pool of candidate trigger factors could be considered in the creation of forecasting models. However, because mechanistic information about causal factors that precede a migraine attack is not well understood, and such factors are difficult to measure, empirical models that are based on trigger factors that are merely associated with the onset of headache activity are likely to be the focus of forecasting efforts in the near future. Of such factors, stress has considerable empirical support and has been used to successfully forecast future headache attacks within individuals over time. However, at present, existing models possess only modest levels of discrimination and lack strong resolution in generated predictions.Summary
Current headache forecasting models represent an important first step in accurately predicting future headache activity. However, to utilize these models in a preemptive treatment paradigm where the risk of headache is treated prior to the actual experience of pain, these models must achieve greater precision with good calibration and generate predictions that are clinically actionable by individuals in their real-time home environments.5.
Purpose of Review
Premonitory symptoms in migraine; symptoms occurring before the onset of migraine pain or aura, are an increasingly recognised area of interest within headache research. It has been recently documented in the literature that these symptoms also occur in children and adolescents, with a comparable phenotype to adults. This review discusses the wide presentation of premonitory symptoms in migraine in children and adolescents, and the importance of understanding how these early symptoms are mediated in order to ensure that targeted abortive therapies are developed in the future. Recognition of these symptoms by parents, guardians, teachers and carers is of importance in ensuring early and effective attack treatment.Recent Findings
A previous clinic-based questionnaire study in 103 children found a prevalence of premonitory symptoms in paediatric migraine of 67%, with a mean number of reported symptoms of two. A recent study found that in a clinic population of 100 children or adolescents with a migraine diagnosis who were preselected as having at least one premonitory symptom associated with their attacks, two or more premonitory symptoms were reported by 85% of patients. The most common symptoms were fatigue, mood change and neck stiffness.Summary
Although the population prevalence of premonitory symptoms in migraine within the paediatric population, or their ability to predict accurately the onset of an impending headache cannot be deduced from the retrospective studies performed to date, premonitory symptoms occur in children as young as 18 months old. Understanding the biological basis of these, and their heterogeneous phenotype may help future targeted therapeutic research, helping the development of drugs that act before the onset of pain, limiting the morbidity associated with the migraine attack.6.

Background
Every professional segment has its own typical forms of stress, which for members result in patterns of bodily conception and interpretation of pain. The way individuals cope with these typical forms of pain reflects their social identity, social status and group membership. In this study pain was investigated from a sociological perspective as a medium contributing to socialization processes in stress collectives.Objectives
Cultural conceptions of headache and migraine were investigated in members of blue collar occupations, in service professions and patients in specialized medical pain care.Materials and methods
In this study 49 qualitative biographical interviews were conducted with patients suffering from headache and migraine. The study population included persons from the general outpatient population and patients recruited from specialized inpatient pain clinics.Results
Members of blue collar occupations with specific body-oriented, mechanical stress patterns and dominant masculine attitudes, perceived headache and migraine as atypical deviations, which are contextualized as body pain. Professionals in the service sector with specific communicative-emotional work patterns perceived headache and migraine as typical and accepted deviations. Both pain conceptions represent dominant body norms and social commitments in each group; however, in specialized pain care these everyday concepts are transformed by increasing expert knowledge resulting in medicalized life styles and in identity conceptions conforming to the medical imperative.Conclusion
The success of specialized treatment of headache depends to a certain extent on the ability of patients to impose a medically regulated life style on their significant others; however, this can conflict with the demands of everyday life.7.

Background
Migraine prevention with erenumab and migraine induction by calcitonin gene-related peptide (CGRP) both carry notable individual variance. We wanted to explore a possible association between individual efficacy of anti-CGRP treatment and susceptibility to migraine induction by CGRP.Methods
Thirteen migraine patients, previously enrolled in erenumab anti-CGRP receptor monoclonal antibody trials, received CGRP in a double-blind, placebo-controlled, randomized cross-over design to investigate their susceptibility to migraine induction. A standardized questionnaire was used to assess the efficacy of previous antibody treatment. The patients were stratified into groups of high responders and poor responders. Primary outcomes were incidence of migraine-like attacks and area under the curve of headache intensity after infusion of CGRP and placebo. All interviews and experiments were performed in laboratories at the Danish Headache Center, Copenhagen, Denmark.Results
Ten high responders and three poor responders were included. CGRP induced migraine-like attacks in ten (77%) patients, whereof two were poor responders, compared to none after placebo (p?=?0.002). The area under the curve for headache intensity was greater after CGRP, compared to placebo, at 0–90 min (p?=?0.009), and 2–12 h (p?=?0.014). The median peak headache intensity score was 5 (5–9) after CGRP, compared to 2 (0–4) after placebo (p?=?0.004).Conclusions
Patients with an excellent effect of erenumab are highly susceptible to CGRP provocation. If an association is evident, CGRP provocation could prove a biomarker for predicting antibody treatment efficacy.Trial registration
Retrospectively registered at clinicaltrials.gov with identifier: NCT03481400.8.
Purpose of Review
CGRP is a key neuropeptide in migraine pathophysiology. The blockade of the CGRP pathway at the side of the CGRP receptor of the CGRP peptide leads to the interruption of trigeminal nerve system-mediated headache syndromes such as migraine. Monoclonal antibodies (mAbs) targeting the CGRP pathway have been developed and are currently under investigation for episodic (EM) and chronic migraine (CM) prevention. Here, we report data from these clinical trials.Recent Findings
Placebo-controlled, randomized double-blind phase studies of CGRP mAbs in episodic and chronic migraine have shown that the specific blockade of the peptide or the CGRP receptor are both powerful mechanisms to reduce migraine frequency. Along with the reduction of acute migraine-specific medication intake, early onset of efficacy of mAbs has been demonstrated. Most common adverse events are injection sider reactions. Depending on the mAb, the administration mode is a monthly or even less frequently s.c. or I.V. formulation.Summary
Phase II studies in EM and CM demonstrate that CGRP mAbs are effective anti-migraine preventatives with a beneficial adverse event profile. Further detailed results from larger phase III clinical trials are expected soon.9.
Purpose of Review
The hippocampus is involved in pain processing, pain-related attention and anxiety, and stress response. The present review compiles the present knowledge of hippocampal volume, activity, and connectivity regarding migraine.Recent Findings
For hippocampal volume, a longitudinal study discovered decreased volume in newly diagnosed migraine patients after 1 year. Two cross-sectional studies suggested an adaptive increase of volume at low headache frequency and a maladaptive decrease of volume at higher headache frequency. Patients who carried a COMT Val homozygous were found to have larger hippocampi on both sides compared with healthy controls with the same polymorphism. For hippocampal activation, one study showed greater nociceptive activation in patients with migraine compared to healthy controls, with the activity correlated to headache frequency. Another study showed greater deactivation and higher functional connectivity linked to other pain-processing regions in low frequency compared to high-frequency migraineurs. At resting state, intraregional functional connectivity of hippocampus was demonstrated to be lower, and connectivity of the hippocampus with other brain regions was different in patients carrying specific genetic variants. For structural connectivity, two studies suggest a stronger connectivity between the hippocampus and other corticolimbic regions, and the altered connectivities are responsible for migraine-associated allodynia or placebo effect of migraine.Summary
Factors including headache frequency, accumulative number of migraine attacks, anxiety score, depression score, and genetic variants are related to hippocampal morphology and functional changes in people with migraine. Future studies should select participants precisely and appropriately control for genetic variants to investigate the complex relationship between the hippocampus and migraine.10.
Purpose of Review
The purpose of this review is to provide an update on the clinical features, diagnosis, pathogenesis, epidemiology, and treatment of the rare primary headache disorders short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) and short-lasting unilateral neuralgiform headache attacks with autonomic symptoms (SUNA). Together these entities are known as short-lasting unilateral neuralgiform headache attacks (SUNHA).Recent Findings
Recent case reports of secondary SUNCT and SUNA due to medullary infarcts support the theory that the trigeminohypothalamic pathway is involved in the pathophysiology of SUNHA. While medical therapy for SUNHA has not significantly changed, surgical therapy for refractory SUNCT and SUNA has made advancements with a recent case series demonstrating the efficacy of deep brain stimulation.Summary
We will discuss the pathophysiology of both the pain and the autonomic symptoms experienced in SUNCT and SUNA attacks as well the medical, procedural, and surgical options for treatment with emphasis on recent advances. Specific secondary causes reported in the recent literature will be discussed in brief.11.

Background
Resting state magnetic resonance imaging allows studying functionally interconnected brain networks. Here we were aimed to verify functional connectivity between brain networks at rest and its relationship with thalamic microstructure in migraine without aura (MO) patients between attacks.Methods
Eighteen patients with untreated MO underwent 3 T MRI scans and were compared to a group of 19 healthy volunteers (HV). We used MRI to collect resting state data among two selected resting state networks, identified using group independent component (IC) analysis. Fractional anisotropy (FA) and mean diffusivity (MD) values of bilateral thalami were retrieved from a previous diffusion tensor imaging study on the same subjects and correlated with resting state ICs Z-scores.Results
In comparison to HV, in MO we found significant reduced functional connectivity between the default mode network and the visuo-spatial system. Both HV and migraine patients selected ICs Z-scores correlated negatively with FA values of the thalamus bilaterally.Conclusions
The present results are the first evidence supporting the hypothesis that an abnormal resting within networks connectivity associated with significant differences in baseline thalamic microstructure could contribute to interictal migraine pathophysiology.12.

Purpose of Review
There is growing interest in neuromodulation for primary headache conditions. Invasive modalities such as occipital nerve stimulation, deep brain stimulation and sphenopalatine ganglion stimulation are reserved for the most severe and intractable patients. Non-invasive options such as vagal nerve stimulation (nVNS), supraorbital nerve stimulation (nSONS) and transcranial magnetic nerve stimulation (TMS) have all emerged as potentially useful headache treatments. This review examines the evidence base for non-invasive neuromodulation in trigeminal autonomic cephalalgias and migraine.Recent Findings
Although a number of open-label series of non-invasive neuromodulation devices have been published, there is very little controlled evidence for their use in any headache condition. Open-label evidence suggests that nVNS may have a role in the prophylactic treatment of cluster headache and there is limited evidence to suggest it may be useful in the acute treatment of cluster and potentially migraine attacks. There is limited controlled evidence to suggest a role for nSONS in the prophylactic treatment of episodic migraine but there is no evidence to support its use in cluster headache. TMS may be efficacious in the acute treatment of episodic migraine has no controlled evidence to support its use as a preventative in any headache condition.Summary
Non-invasive neuromodulation techniques are an attractive treatment option with excellent safety profiles but their use is not yet supported by high-quality randomised controlled trials.14.

Purpose of Review
This article reviews the recent research and development of electronic health (eHealth) and, in particular, mobile health (mHealth) strategies to deliver behavioral treatment for migraine. Prospects for future development and research of mobile health in migraine are suggested.Recent Findings
Advances in digital technology and mobile technology have led to an era where electronic and mobile approaches are applied to several aspects of healthcare. Electronic behavioral interventions for migraine seem to be acceptable and feasible, but efficacy measures are uncertain. Clinical trials on mHealth-based classical behavioral therapies, such as relaxation, biofeedback, and cognitive behavioral therapy are missing in the literature. Within mHealth, headache diaries are the most researched and scientifically developed. Still, there is a gap between commercially available apps and scientifically validated and developed apps.Summary
Digital technology and mobile health has not yet lived out its potential in behavioral migraine therapy. Application of proper usability and functionality designs towards the right market, together with appraisal of medical and technological recommendations, may facilitate rapid development of eHealth and mHealth, while also establishing scientific evidence.16.
Background
Subcutaneous peripheral nerve field stimulation (sPNFS) is an established procedure for the treatment of chronic localized neuropathic pain of peripheral origin. The treatment of nummular headache primarily focuses on conservative methods with limited prospects of success. The role of sPNFS in the treatment of nummular headache has not been investigated as yet.Question
Is the sPNFS an option in the management of nummular headache?Materials and methods
In addition to a summary of established methods in the treatment of nummular headache, sPNFS as a possible form of therapy is discussed.Results
A positive effect of sPNFS in terms of the treatment of nummular headache is shown.Discussion
sPNFS stimulates free subcutaneous nerves and transmits a pleasant form of paraesthesia in the area of pain. If regular conservative therapy has already been exhausted, then sPNFS might be an effective new option in the treatment of nummular headache. sPNFS is a minimally invasive and low-risk procedure. However, the high treatment cost and restrictions regarding fitness to undergo MRI are points of criticism. Further studies are needed to define its potential and role in the treatment of nummular headache.17.
Purpose of Review
In this short review, the most common non-invasive neuromodulatory techniques will be described, along with their advantages and disadvantages and their application in headache. Available preventive treatments can be unhelpful or may have unpleasant side effects; moreover, the rate of response to preventive drugs does not exceed 50%, lower in chronic migraine; alternative options would be welcome. Though the concept of neuromodulation was originally developed with invasive methods, newer non-invasive techniques are appearing.Recent Findings
The novel neuromodulatory techniques have been developed with encouraging results: compared with traditional pharmacotherapy, advantages of non-invasive neuromodulation include reduced incidence of adverse effects, improved adherence, and safety and ease of use. The results are encouraging for acute or preventive treatment of different kinds of headache.Summary
A variety of neuromodulatory approaches is expanding fastly and has opened new possibilities for treatment of patients suffering from many forms of headache, especially those who have failed traditional pharmacotherapy. The non-invasive treatments can be seen as supplementing traditional management in refractory patients. Current study results are encouraging but preliminary and larger and more rigorous trials are needed to clarify benefit and mode of action.18.

Purpose of review
The goal of this review is to provide an actualized overview on vestibular migraine in childhood and adolescence, with focus on the epidemiology and clinical presentation as well as its treatment.Recent findings
Vertigo spells in childhood can evolve into other periodic syndromes and/or migraine types and persist even into adulthood.Summary
Vestibular migraine (VM) and benign paroxysmal vertigo are the most common causes of vertigo in children and adolescents. The diagnostic criteria for VM are dizziness and vertigo, headache, phonophobia and photophobia, and visual aura. The prevention of attacks is the treatment for children and adolescents with VM, as is recommended for migraine with or without aura. Thus, non-pharmacological measures are the first-line option; when these measures fail or daily activities are notably affected, drugs are administrated. Psychological assessment and cognitive behavioral therapy are also important therapeutic measures in this patient group. There is still insufficient research on VM in children and adolescents; future studies on clinical presentation, evolvement, and specific treatment are necessary.19.
Purpose of Review
Recurrent painful ophthalmoplegic neuropathy (RPON), formerly known as ophthalmoplegic migraine, is an uncommon disorder with repeated episodes of ocular cranial nerve neuropathy associated with ipsilateral headache. This review discusses the clinical presentation, current understanding of the pathophysiology, key differential diagnoses, and evaluation and treatment of RPON.Recent Findings
The literature is limited due to the rarity of the disorder. Recent case reports and series continue to suggest the age of first attack is most often during childhood or adolescence as well as a female predominance. Multiple recent case reports and series demonstrate focal enhancement of the affected cranial nerve, as the nerve root exits the brainstem. This finding contributed to the current classification of the disorder as a neuropathy, with the present understanding that it is due to a relapsing-remitting inflammatory or demyelinating process. The link to migraine remains a cause of disagreement in the literature.Summary
RPON is a complex disorder with features of inflammatory neuropathy and an unclear association with migraine. Regardless, the overall prognosis is good for individual episodes, but permanent nerve damage may accumulate with repeated attacks. A better understanding of the pathogenesis is needed to clarify whether it truly represents a single disorder and to guide its treatment. Until that time, a combined approach with acute and preventive therapies can mitigate acute symptoms as well as attempt to limit recurrence of this disabling syndrome.20.
