Abstract
Headache disorders, particularly migraine, are one of the most common and disabling neurological disorders. There is a need for high-quality, accessible care for patients with headache disorders across all levels of the healthcare system in Singapore. The role of the Headache Society of Singapore is to increase awareness and advance the understanding of these disorders and to advocate for the needs of affected patients. In this first edition of local consensus guidelines, we focus on treatment approaches for headaches and provide consensus recommendations for the management of migraine in adults. The recommendations in these guidelines can be used as a practical tool in routine clinical practice by primary care physicians, neurologists and other healthcare professionals who have a common interest in headache disorders.

Abstract
Migraine is a hereditary disease, usually one-sided, sometimes bilateral. It is characterized by moderate to severe pain, which worsens with physical activity and may be associated with nausea and vomiting, may be accompanied by photophobia and phonophobia. The disorder can occur at any time of the day and can last from 4 to 72 h, with and without aura. The pathogenic mechanism is unclear, but extensive preclinical and clinical studies are ongoing. According to electrophysiology and imaging studies, many brain areas are involved, such as cerebral cortex, thalamus, hypothalamus, and brainstem. The activation of the trigeminovascular system has a key role in the headache phase. There also appears to be a genetic basis behind the development of migraine. Numerous alterations have been identified, and in addition to the genetic cause, there is also a close association with the surrounding environment, as if on the one hand, the genetic alterations may be responsible for the onset of migraine, on the other, the environmental factors seem to be more strongly associated with exacerbations. This review is an analysis of neurophysiological mechanisms, neuropeptide activity, and genetic alterations that play a fundamental role in choosing the best therapeutic strategy. To date, the goal is to create a therapy that is as personalized as possible, and for this reason, steps forward have been made in the pharmacological field in order to identify new therapeutic strategies for both acute treatment and prophylaxis.

Abstract
So far, no coherent and convincing theory has been developed to fully explain the pathogenesis of migraine, although many researchers and experts emphasize its association with spreading cortical depression, oxidative stress, vascular changes, nervous excitement, neurotransmitter release, and electrolyte disturbances. The contribution of magnesium deficiency to the induction of cortical depression or abnormal glutamatergic neurotransmission is a likely mechanism of the magnesium–migraine relationship. Hence, there is interest in various methods of assessing magnesium ion deficiency and attempts to study the relationship of its intra- and extracellular levels with the induction of migraine attacks. At the same time, many clinicians believe that magnesium supplementation in the right dose and form can be a treatment to prevent migraine attacks, especially in those patients who have identified contraindications to standard medications or their different preferences. However, there are no reliable publications confirming the role of magnesium deficiency in the diet as a factor causing migraine attacks. It also seems interesting to deepen the research on the administration of high doses of magnesium intravenously during migraine attacks. The aim of the study was to discuss the probable mechanisms of correlation of magnesium deficiency with migraine, as well as to present the current clinical proposals for the use of various magnesium preparations in complementary or substitute pharmacotherapy of migraine. The summary of the results of research and clinical observations to date gives hope of finding a trigger for migraine attacks (especially migraine with aura), which may turn out to be easy to diagnose and eliminate with pharmacological and dietary supplementation.

Abstract
INTRODUCTION In June of 2020, the U.S. DVA and DoD approved a new joint clinical practice guideline for assessing and managing patients with headache. This guideline provides a framework to evaluate, treat, and longitudinally manage the individual needs and preferences of patients with headache. METHODS In October of 2018, the DVA/DoD Evidence-Based Practice Work Group convened a guideline development panel that included clinical stakeholders and conformed to the National Academy of Medicine's tenets for trustworthy clinical practice guidelines. RESULTS The guideline panel developed key questions, systematically searched and evaluated the literature, created a 1-page algorithm, and advanced 42 recommendations using the Grading of Recommendations Assessment, Development, and Evaluation system. CONCLUSION This synopsis summarizes the key features of the guideline in three areas: prevention, assessing and treating medication overuse headache, and nonpharmacologic and pharmacologic management of headache.

Abstract
Background: Magnesium (Mg) is commonly used in clinical practice for acute and chronic pain and has been reported to reduce pain intensity and analgesics consumption in a number of studies. Results are, however, contested. Objectives: This review aims to investigate randomised clinical trials (RCTs) on the effectiveness of Mg treatment on pain and analgesics consumption in situations including post-operative pain, migraine, renal pain, chronic pain, neuropathic pain and fibromyalgia. Results: The literature search identified 81 RCTs (n = 5447 patients) on Mg treatment in pain (50 RCTs in post-operative pain, 18 RCTs in migraine, 5 RCTs in renal pain, 6 RCTs in chronic/neuropathic pain, 2 RCTs in fibromyalgia). Conclusion: The level of evidence for the efficacy of Mg in reducing pain and analgesics consumption is globally modest and studies are not very numerous in chronic pain. A number of gaps have been identified in the literature that need to be addressed especially in methodology, rheumatic disease, and cancer. Additional clinical trials are needed to achieve a sufficient level of evidence and to better optimize the use of Mg for pain and pain comorbidities in order to improve the quality of life of patients who are in pain.

Abstract
Objective This study aimed to assess the efficacy of concurrent magnesium-sodium valproate therapy and compare it with either magnesium or sodium valproate alone in migraine prophylaxis. Materials and methods This randomized single-center double-blind parallel-group controlled clinical trial study was conducted on migraine patients within the age range of 18–65 years. The subjects with at least four monthly attacks were randomly assigned to group A (n = 82) sodium valproate, group B (n = 70) magnesium with sodium valproate, and group C (n = 70) magnesium. The patients passed a one-month baseline without prophylactic therapy and then received a 3-month treatment. The characteristics of migraine, including frequency, severity, duration of the attacks, and the number of painkillers taken per month, were monthly recorded in each visit. The Migraine Disability Assessment (MIDAS) and Headache Impact Test-6 (HIT-6) scores were recorded at the baseline and after 3 months of treatment in each group. Within- and between-group analyses were performed in this study. Results The obtained results revealed a significant reduction in all migraine characteristics in all groups compared to those reported for the baseline (P < 0.001). Intragroup data analysis indicated that there was no statistically significant difference in headache frequency between groups A and B in the third month (P = 0.525); nevertheless, three other parameters showed a significant reduction in group B, compared to those reported for group A in the third month (P < 0.05). On the other hand, group C could not effectively reduce measured parameters in the patients, compared to groups A and B after 3 months (P < 0.001). Furthermore, the MIDAS and HIT-6 scores significantly diminished in groups A, B, and C compared to those reported at the baseline (P < 0.001), and these changes were more significant in groups A and B than in group C (P < 0.001). Conclusion The obtained results of this study revealed that magnesium could enhance the antimigraine properties of sodium valproate in combination therapy and reduce the required valproate dose for migraine prophylaxis.

Abstract
Magnesium deficiency may occur for several reasons, such as inadequate intake or increased gastrointestinal or renal loss. A large body of literature suggests a relationship between magnesium deficiency and mild and moderate tension-type headaches and migraines. A number of double-blind randomized placebo-controlled trials have shown that magnesium is efficacious in relieving headaches and have led to the recommendation of oral magnesium for headache relief in several national and international guidelines. Among several magnesium salts available to treat magnesium deficiency, magnesium pidolate may have high bioavailability and good penetration at the intracellular level. Here, we discuss the cellular and molecular effects of magnesium deficiency in the brain and the clinical evidence supporting the use of magnesium for the treatment of headaches and migraines.

Abstract
Migraine is one of the most common recurrent types of headache and is the seventh cause of disability. This neurological disorder is characterized by having pain in head and other various symptoms such as nausea, emesis, photophobia, phonophobia, and sometimes visual sensory disorders. Magnesium (Mg) is a necessary ion for human body and has a crucial role in health and life maintenance. One of the main roles of Mg is to conserve neurons electric potential. Therefore, magnesium deficiency can cause neurological complications. Migraine is usually related to low amounts of Mg in serum and cerebrospinal fluid (CSF). Deficits in magnesium have significant role in the pathogenesis of migraine. Mg has been extensively used in migraine prophylaxis and treatment. This review summarizes the role of Mg in migraine pathogenesis and the potential utilizations of Mg in the prevention and treatment of migraine with the emphasis on transdermal magnesium delivery.

Abstract
Pseudo-benign paroxysmal positional vertigo (pseudo-BPPV) is a specific type of vestibular migraine disguised as benign paroxysmal positional vertigo, which is characterized by recurrent different types of positional and atypical positional vertigo with migraine features. It is easy to be misdiagnosed with BPPV at the first visit, which means that the ideal therapeutic effects are not achieved. Twenty-five cases of pseudo-BPPV with frequent changing positional vertigo were retrospected and the following key features help to identify the disease: recurrent positional and atypical positional vertigo, migrainous accompanying symptoms or migraine history, mild or indistinctive headaches, with or without impaired vestibular function, ineffective for simply reposition. And we found that vertigo in pseudo-BPPV can be preferable controlled by valproic acid combined with canalith repositioning procedure.

Abstract
Introduction: Most preventive migraine treatments modify the brain's excitation/inhibition balance and/or serotonin metabolism, which likely accounts for their unfavorable adverse effect profile. Novel biological therapies blocking CGRP transmission are effective and better tolerated, but they are expensive and may not influence brain dysfunctions upstream in the pathophysiological cascade of migraine, including premonitory and aura symptoms. Biochemical and clinical studies suggest that there may be another complimentary treatment strategy, the one that targets the underestimated metabolic facet of migraine pathophysiology.Areas covered: After a brief description of the metabolic abnormalities found in migraine patients, we will review and discuss published data on metabolic treatments of migraine. There is evidence that riboflavin and co-enzyme Q10 are effective for the prevention of migraine and quasi devoid of adverse effects. Response rates are close to those of topiramate, propranolol, and CGRP/CGRPrec mAbs. The evidence is weaker for thioctic acid. Dietary and pharmacological strategies inducing ketosis are novel promising approaches for which preliminary trials with favorable outcomes have been published.Expert opinion: Metabolic treatments of migraine constitute an effective, well-tolerated, inexpensive, and evidence-supported therapeutic option for migraine prophylaxis, and may be considered as first treatment line in many patients, including in children and adolescents.

Abstract
Aims To evaluate the crossover design in migraine preventive treatment trials by assessing dropout rate, and potential period and carryover effect in four placebo-controlled randomized controlled trials (RCTs). Methods In order to increase statistical power, the study combined data from four different RCTs performed from 1998 to 2015 at St. Olavs Hospital, Norway. Among 264 randomized patients, 120 received placebo treatment before and 144 after active treatment. Results Only 26 (10%) dropped out during the follow-up period of 30–48 weeks, the majority (n = 19) in the first 12 weeks. No period effect was found, since the treatment sequence did not influence the responder rate after placebo treatment, being respectively for migraine 30.5% vs. 27.4% (p = 0.59) and for headache 25.0% vs. 24.8% (p = 0.97, Chi-square test) when placebo occurred early or late. Furthermore, no carryover effect was identified, since the treatment sequence did not influence the treatment effect (difference between placebo and active treatment). There was no significant difference between those who received active treatment first and those who received placebo first with respect to change in number of days per 4 week of headache (− 0.9 vs. -1.3, p = 0.46) and migraine (− 1.2 vs. -0.9, p = 0.35, Student’s t-test). Conclusions Summary data from four crossover trials evaluating preventive treatment in adult migraine showed that few dropped out after the first period. No period or carryover effect was found. RCT studies with crossover design can be recommended as an efficient and cost-saving way to evaluate potential new preventive medicines for migraine in adults.

Abstract
Migraine can be regarded as a conserved, adaptive response that occurs in genetically predisposed individuals with a mismatch between the brain's energy reserve and workload. Given the high prevalence of migraine, genotypes associated with the condition seem likely to have conferred an evolutionary advantage. Technological advances have enabled the examination of different aspects of cerebral metabolism in patients with migraine, and complementary animal research has highlighted possible metabolic mechanisms in migraine pathophysiology. An increasing amount of evidence - much of it clinical - suggests that migraine is a response to cerebral energy deficiency or oxidative stress levels that exceed antioxidant capacity and that the attack itself helps to restore brain energy homeostasis and reduces harmful oxidative stress levels. Greater understanding of metabolism in migraine offers novel therapeutic opportunities. In this Review, we describe the evidence for abnormalities in energy metabolism and mitochondrial function in migraine, with a focus on clinical data (including neuroimaging, biochemical, genetic and therapeutic studies), and consider the relationship of these abnormalities with the abnormal sensory processing and cerebral hyper-responsivity observed in migraine. We discuss experimental data to consider potential mechanisms by which metabolic abnormalities could generate attacks. Finally, we highlight potential treatments that target cerebral metabolism, such as nutraceuticals, ketone bodies and dietary interventions.
