Review
The role of neuroinflammation in the pathophysiology of migraines is increasingly being recognized, and cytokines, which are important endogenous substances involved in immune and inflammatory responses, have also received attention. This review examines the current literature on neuroinflammation in the pathogenesis of migraine. Elevated TNF-α, IL-1β, and IL-6 levels have been identified in non-invasive mouse models with cortical spreading depolarization (CSD). Various mouse models to induce migraine attack-like symptoms also demonstrated elevated inflammatory cytokines and findings suggesting differences between episodic and chronic migraines and between males and females. While studies on human blood during migraine attacks have reported no change in TNF-α levels and often inconsistent results for IL-1β and IL-6 levels, serial analysis of cytokines in jugular venous blood during migraine attacks revealed consistently increased IL-1β, IL-6, and TNF-α. In a study on the interictal period, researchers reported higher levels of TNF-α and IL-6 compared to controls and no change regarding IL-1β levels. Saliva-based tests suggest that IL-1β might be useful in discriminating against migraine. Patients with migraine may benefit from a cytokine perspective on the pathogenesis of migraine, as there have been several encouraging reports suggesting new therapeutic avenues.

Review
Cluster headache and migraine are regarded as distinct primary headaches. While cluster headache and migraine differ in multiple aspects such as gender-related and headache specific features (e.g., attack duration and frequency), both show clinical similarities in trigger factors (e.g., alcohol) and treatment response (e.g., triptans). Here, we review the similarities and differences in anatomy and pathophysiology that underlie cluster headache and migraine, discuss whether cluster headache and migraine should indeed be considered as two distinct primary headaches, and propose recommendations for future studies. Video recording of the debate held at the 1st International Conference on Advances in Migraine Sciences (ICAMS 2022, Copenhagen, Denmark) is available at https://www.youtube.com/watch?v=uUimmnDVTTE .

Review
Headache is a common complaint and is often benign. When patients with cancer describe new headaches, it is important to ensure that there are no emergent or concerning etiologies, including metastatic disease. This review article details primary and secondary headaches. Red flags-the do-not-miss warning signs-are described. An initial approach to the evaluation, including suggestions for imaging, features to look for in a targeted examination, and when to request a consultation, is outlined. An overview of headache etiologies is described with a particular emphasis on the most common types: migraine and tension. The classification of headaches, based on criteria from the International Classification of Headache Disorders (3rd edition; beta version), is reviewed. Medications used for treatment, including newer biological agents, are described, and there are details about both abortive and preventive medication therapies. Suggestions for complementary and integrative therapies, some of which may be synergistic in treating other cancer symptoms, are outlined; they include mindfulness therapies, which are gaining traction in treating a variety of medical conditions. Readers should have an understanding of headache evaluation in patients with cancer and should know how to formulate a plan for a diagnosis. In addition, readers will gain familiarity with common treatments, both pharmacological and complementary/integrative.

Review
Riboflavin, a water-soluble member of the B-vitamin family, plays a vital role in producing energy in mitochondria and reducing inflammation and oxidative stress. Migraine pathogenesis includes neuroinflammation, oxidative stress, and mitochondrial dysfunction. Therefore, riboflavin is increasingly being recognized for its preventive effects on migraines. However, there is no concrete evidence supporting its use because the link between riboflavin and migraines and the underlying mechanisms remains obscure. This review explored the current experimental and clinical evidence of conditions involved in migraine pathogenesis and discussed the role of riboflavin in inhibiting these conditions. Experimental research has demonstrated elevated levels of various oxidative stress markers and pro-inflammatory cytokines in migraines, and riboflavin's role in reducing these marker levels. Furthermore, clinical research in migraineurs showed increased marker levels and observed riboflavin's effectiveness in reducing migraines. These findings suggest that inflammation and oxidative stress are associated with migraine pathogenesis, and riboflavin may have neuroprotective effects through its clinically useful anti-inflammatory and anti-oxidative stress properties. Riboflavin's safety and efficacy suggests its usefulness in migraine prophylaxis; however, insufficient evidence necessitates further study.

Review
BACKGROUND
Migraine and epilepsy are two paroxysmal chronic neurological disorders affecting a high number of individuals and being responsible for a high individual and socioeconomic burden. The link between these disorders has been of interest for decades and innovations concerning diagnosing and treatment enable new insights into their relationship.
FINDINGS
Although appearing to be distinct at first glance, both diseases exhibit a noteworthy comorbidity, shared pathophysiological pathways, and significant overlaps in characteristics like clinical manifestation or prophylactic treatment. This review aims to explore the intricate relationship between these two conditions, shedding light on shared pathophysiological foundations, genetic interdependencies, common and distinct clinical features, clinically overlapping syndromes, and therapeutic similarities. There are several shared pathophysiological mechanisms, like CSD, the likely underlying cause of migraine aura, or neurotransmitters, mainly Glutamate and GABA, which represent important roles in triggering migraine attacks and seizures. The genetic interrelations between the two disorders can be observed by taking a closer look at the group of familial hemiplegic migraines, which are caused by mutations in genes like CACNA1A, ATP1A2, or SCN1A. The intricate relationship is further underlined by the high number of shared clinical features, which can be observed over the entire course of migraine attacks and epileptic seizures. While the variety of the clinical manifestation of an epileptic seizure is naturally higher than that of a migraine attack, a distinction can indeed be difficult in some cases, e.g. in occipital lobe epilepsy. Moreover, triggering factors like sleep deprivation or alcohol consumption play an important role in both diseases. In the period after the seizure or migraine attack, symptoms like speech difficulties, tiredness, and yawning occur. While the actual attack of the disease usually lasts for a limited time, research indicates that individuals suffering from migraine and/or epilepsy are highly affected in their daily life, especially regarding cognitive and social aspects, a burden that is even worsened using antiseizure medication. This medication allows us to reveal further connections, as certain antiepileptics are proven to have beneficial effects on the frequency and severity of migraine and have been used as a preventive drug for both diseases over many years.
CONCLUSION
Migraine and epilepsy show a high number of similarities in their mechanisms and clinical presentation. A deeper understanding of the intricate relationship will positively advance patient-oriented research and clinical work.

BACKGROUND
Adults who suffer from migraines are highly susceptible to mental illnesses that may have significant association with their HRQoL. Therefore, this study aimed to investigate how anxiety and depression related to HRQoL in adults with Migraine.
METHODS
Data from the Medical Expenditure Panel Survey for 2017 to 2020 were used to identify adult patients 18 years of age and older with a migraine diagnosis. The Physical and Mental Component Summary (PCS & MCS) scores from the SF-12 were used to calculate HRQoL. To adjust for a wide range of variables, multivariate linear regressions were used to evaluate the association between depression and anxiety and HRQoL among adults with migraine.
RESULTS
Among the 1,713 identified adults with migraines, 11.2% experienced depression, 14.6% experienced anxiety, and 13.7% had both conditions. Compared to migraineurs who had only migraine, adults with comorbid depression and anxiety had the lowest mean scores on the PCS and MCS. Additionally, migraineurs who had depression had significantly lower HRQoL MCS scores (depression: β = -7.552, < 0.001), and those with anxiety had significantly lower HRQoL MCS scores (anxiety: β = -4.844, p < 0.001) compared to those without these comorbidities. Notably, individuals with migraines who exercise had higher scores on both PCS and MCS than those who did not exercise.
CONCLUSION
This nationally representative sample provides insights into the associations between depression and anxiety with poor HRQoL among individuals with migraines. Additionally, it revealed the negative impact of concurrent chronic diseases, and poor socioeconomic status on HRQoL, while emphasizing the beneficial effects of regular exercise. This study highlights the clinical, policy, and public health implications for improving healthcare planning, resource allocation, and promoting lifestyle changes to reduce depression and anxiety in migraine sufferers.

Review
Migraine-a primary headache-has circadian and circannual rhythms in the onset of attacks. The circadian and circannual rhythms involve the hypothalamus, which is strongly associated with pain processing in migraines. Moreover, the role of melatonin in circadian rhythms has been implied in the pathophysiology of migraines. However, the prophylactic effect of melatonin in migraines is controversial. Calcitonin gene-related peptide (CGRP) has recently attracted attention in the pathophysiology and treatment of migraines. Pituitary adenylate cyclase-activating peptide (PACAP)-a neuropeptide identical to CGRP-is a potential therapeutic target after CGRP. PACAP is involved in the regulation of circadian entrainment to light. This review provides an overview of circadian and circannual rhythms in the hypothalamus and describes the relationship between migraines and the molecular and cellular neurobiology of circadian and circannual rhythms. Furthermore, the potential clinical applications of PACAP are presented.

Review
Migraines are a common form of primary headache, affecting women more than men (17.4% and 5.7% of US population, respectively, a total of 12%) that carry significant morbidity and disability, as well as a hefty healthcare price tag. They are most prevalent in women of reproductive ages and are estimated to be the 6th disease in order of causing global burden. They are estimated to cause 45.1 million years lived with disability, or 2.9% of global years lost to disability. Migraine treatment divides into acute, abortive treatment for relief of an ongoing migraine attack, and prophylactic therapy to reduce the occurrence of migraines, specifically for patients suffering from chronic and frequent episodic migraines. Traditional abortive treatment usually begins with NSAID and non-specific analgesics that are effective in curbing mild to moderate attacks. 5HT-agonists, such as triptans, are often used for second-line and for severe attacks. Triptans are generally better tolerated in the longterm than NSAIDs and other analgesics, though they carry a significant side-effect profile and are contraindicated in large parts of the population. Prophylactic therapy is usually reserved for patients with frequent recurrence owing to medication side effects and overall poor adherence to the medication schedule. Importantly, medication overuse may actually lead to the development of chronic migraines from previously episodic attacks. Recent research has shed more light on the pathophysiology of migraine and the role of CGRP in the trigeminovascular system. Recent pharmacological advances were made in developing more specific drugs based on this knowledge, including CGRP neutralizing antibodies, receptor antagonists, and the development of ditans. These novel drugs are highly specific to peripheral and central 5-HT receptors and effective in the treatment of acute migraine attacks. Binding these receptors reduces the production of CGRP and Glutamate, two important ligands in the nociceptive stimulus involved with the generation and propagation of migraines. Several large clinical studies showed Lasmiditan to be effective in the treatment of acute migraine attacks. Importantly, due to its receptor specificity, it lacks the vasoconstriction that is associated with triptans and is thus safer is larger parts of the population, specifically in patients with cardiac and vascular disease. Though more research is required, specifically with aftermarket surveillance to elucidate rare potential side effects, Lasmiditan is a targeted anti-migraine drug that is both safe and effective, and carries an overall superior therapeutic profile to its predecessors. It joins the array of medications that target CGRP signaling, such as gepants and CGRP-antibodies, to establish a new line of care for this common disabling condition.

Review
PURPOSE OF REVIEW
Historical evidence suggests a shared underlying etiology for migraine and gastrointestinal (GI) disorders that involves the gut-brain axis. Here we provide narrative review of recent literature on the gut-brain connection and migraine to emphasize the importance of tailoring treatment plans for patients with episodic migraine who experience GI comorbidities and symptoms.
RECENT FINDINGS
Recent population-based studies report the prevalence of migraine and GI disorders as comorbidities as well as overlapping symptomology. American Headache Society (AHS) guidelines have integrated GI symptoms as part of migraine diagnostic criteria and recommend nonoral therapies for patients with GI symptoms or conditions. Nasal delivery is a recommended nonoral alternative; however, it is important to understand potential adverse events that may cause or worsen GI symptoms in some patients due to the site of drug deposition within the nasal cavity with some nasal therapies. Lastly, clinical perspectives emphasize the importance of identifying GI symptoms and comorbidities in patients with episodic migraine to best individualize migraine management. Support for an association between the gut-brain axis and migraine continues to prevail in recent literature; however, the relationship remains complex and not well elucidated. The presence of GI comorbidities and symptoms must be carefully considered when making treatment decisions for patients with episodic migraine.
