Abstract
Migraine with brainstem aura has been long described but remains poorly understood. Previously known as "basilar" or "basilar artery" migraine, it is an uncommon subtype of migraine with aura, one seen primarily in children, adolescents, and younger adults. The condition is characterized by migraine headache accompanied by several neurological symptoms conventionally assigned to dysfunction of brainstem structures. Initially felt to be vascular in origin, partly due to prevailing concepts of migraine pathophysiology at the time, most now believe the aura symptoms of migraine with brainstem aura are secondary to neural circuitry dysfunction. The differential diagnosis is reasonably broad, and most patients warrant investigation to exclude conditions bearing high degrees of morbidity and mortality. Neuroimaging, specifically brain MRI without contrast, is recommended for migraine with brainstem aura. Depending on the clinical presentation certain cases may require consideration of contrasted or vascular imaging, EEG, or lumbar puncture with cerebrospinal fluid analysis. Migraine prophylaxis should involve lifestyle adjustments and preventive medical therapies shown to be effective in clinical trials of migraine, following evidence-based guidelines. The acute pharmacological management of attacks of migraine with brainstem aura remains a matter of controversy. The prognosis is generally favorable. Future refinements in the diagnostic criteria might possibly enhance diagnostic specificity and improved clinical research.

Abstract
Hemiplegic migraine (HM) is a rare subtype of migraine with aura in which the aura phase includes transient motor weakness. Diagnosis is based on the International Classification of Headache Disorders criteria (ICHD-3). The most important diagnostic tools remain a patient interview, neurological examination during attacks, and exclusion of other disorders, such as epilepsy, stroke, encephalitis and secondary headache syndromes. Hemiplegic migraine can occur either familial or sporadic. Three genes, CACNA1A, ATP1A2, and SCN1A have been identified. Taken together, mutations in these three genes predict increased neurotransmitter and potassium ion levels at the synaptic cleft, which facilitates cortical spreading depolarization, the phenomenon underlying the migraine aura. The presence of several symptoms, including extensive weakness and brainstem manifestations increase the likelihood of finding a monogenic cause. While the diagnosis can be confirmed by genetic testing, it cannot be excluded if one of the known (F)HM genes is not implicated. Most patients with hemiplegic migraine without a mutation in CACNA1A, ATP1A2, or SCN1A display a mild phenotype that is more akin to that of common (nonhemiplegic) migraine. Additional diagnostics such as brain imaging, cerebrospinal fluid analysis or an electroencephalography are mainly performed to exclude other causes of focal neurologic symptoms associated with hemiparesis and headache. Due to the rarity of the disorder, current treatment recommendations are based on small, unblinded studies and empirical data.

Abstract
INTRODUCTION Migraine is a leading cause of disability and suffering worldwide. However, conventional pharmacological migraine preventive therapies are often challenging and accompanied by adverse effects. Recently, structured odour exposure has shown to successfully increase pain thresholds in patients with chronic back pain. Despite the importance of the olfactory system in migraine, there are no studies investigating the impact of structured odour exposure in patients with migraine. METHODS AND ANALYSIS This double-blind randomised placebo-controlled trial will be conducted at the Headache Clinic of the University Pain Center at TU Dresden, Germany and aims at investigating the impact of a 12-week structured exposure to odours in women with migraine. Fifty-four women between 18 and 55 years with migraine with aura will be recruited and randomised to training with odours and odourless training. The primary outcomes are mechanical and electrical pain thresholds. Secondary outcomes comprise olfactory threshold and the number of headache days. Other exploratory measurements are headache associated pain intensity, acute analgesic intake, symptoms of anxiety and depression, and quality of life. Additionally, this protocol assesses neuroanatomical and neurofunctional changes associated with the 12-week olfactory training. Data analysis will be executed on the basis of the general linear model considering repeated measurements. ETHICS AND DISSEMINATION Ethical approvals were obtained from the Ethics Board of the TU Dresden (Protocol No. BO-EK-353082020). Participation will only be possible after written informed consent is provided. Findings will be disseminated through peer-reviewed journals and scientific conferences. TRIAL REGISTRATION NUMBER DRKS00027399.

Abstract
OBJECTIVE This systematic review provides a summary and evaluation of cases of migraine aura-like episodes elicited by sclerotherapy of veins of the lower extremities and discusses possible underlying mechanisms. BACKGROUND Sclerotherapy is a commonly used treatment for varicose veins. Symptoms resembling migraine aura have been reported during and following sclerotherapy of the lower extremities, suggesting that sclerotherapy may elicit migraine aura. METHODS We searched PubMed for articles reporting neurological complications that were transient and fully reversible following sclerotherapy treatment for varicose veins in the lower limbs. There were no restrictions regarding article language or publication date. Only original studies and case reports were included. Two authors independently reviewed included articles in detail. Data were extracted from each article, including details on symptoms, previous migraine history, sclerotherapy method, and the presence of a right-to-left cardiac shunt in patients. We evaluated whether episodes fulfilled modified International Classification of Headache Disorders, 3rd edition, criteria for 1.2 Migraine with aura or 1.5.2 Probable migraine with aura. RESULTS The search yielded 777 articles, 28 of which were included. Twenty-six articles reported 119 episodes of transient neurological symptoms in 34,500 sclerotherapy sessions. Two additional articles reported six episodes of transient neurological symptoms with no specification of the number of sessions. Of the 125 episodes, 119 involved transient visual disturbances, and eight met the modified criteria for Probable migraine with aura. In most episodes (98%), clinical information was insufficient to determine if the criteria were fulfilled. CONCLUSIONS Symptoms that are clinically indistinguishable from migraine with aura attacks may occur following sclerotherapy, although this likely is rare. Microembolization through a right-to-left shunt triggering cortical spreading depolarization is a possible mechanism. Our findings are limited by infrequent specific assessments for neurological complications and a low level of detail in the description of symptoms in the available literature. Future prospective studies are needed to determine this phenomenon's incidence and underlying mechanisms.

Abstract
This chapter describes the different types of aura including rare aura subtypes such as retinal aura. In addition, aura manifestations not classified in the International Classification of Headache Disorders and auras in headache disorders others than migraine are also described. The differential diagnosis of migraine aura comprises several neurological disorders which should be known to specialists. Migraine aura also has impact on the choice of migraine treatment; recommendations for the treatment of the migraine aura itself are also presented in this chapter.

Abstract
OBJECTIVE To assess the efficacy of manual acupuncture as prophylactic treatment for acupuncture naive patients with episodic migraine without aura. DESIGN Multicentre, randomised, controlled clinical trial with blinded participants, outcome assessment, and statistician. SETTING Seven hospitals in China, 5 June 2016 to 15 November 2018. PARTICIPANTS 150 acupuncture naive patients with episodic migraine without aura. INTERVENTIONS 20 sessions of manual acupuncture at true acupuncture points plus usual care, 20 sessions of non-penetrating sham acupuncture at heterosegmental non-acupuncture points plus usual care, or usual care alone over 8 weeks. MAIN OUTCOME MEASURES Change in migraine days and migraine attacks per four weeks during weeks 1-20 after randomisation compared with baseline (four weeks before randomisation). RESULTS Among 150 randomised patients (mean age 36.5 (SD 11.4) years; 123 (82%) women), 147 were included in the full analysis set. Compared with sham acupuncture, manual acupuncture resulted in a significantly greater reduction in migraine days at weeks 13 to 20 and a significantly greater reduction in migraine attacks at weeks 17 to 20. The reduction in mean number of migraine days was 3.5 (SD 2.5) for manual versus 2.4 (3.4) for sham (adjusted difference -1.4, 95% confidence interval -2.4 to -0.3; P=0.005) at weeks 13 to 16 and 3.9 (3.0) for manual versus 2.2 (3.2) for sham (adjusted difference -2.1, -2.9 to -1.2; P<0.001) at weeks 17 to 20. At weeks 17 to 20, the reduction in mean number of attacks was 2.3 (1.7) for manual versus 1.6 (2.5) for sham (adjusted difference -1.0, -1.5 to -0.5; P<0.001). No severe adverse events were reported. No significant difference was seen in the proportion of patients perceiving needle penetration between manual acupuncture and sham acupuncture (79% v 75%; P=0.891). CONCLUSIONS Twenty sessions of manual acupuncture was superior to sham acupuncture and usual care for the prophylaxis of episodic migraine without aura. These results support the use of manual acupuncture in patients who are reluctant to use prophylactic drugs or when prophylactic drugs are ineffective, and it should be considered in future guidelines.

Abstract
Migraine is a major public health problem afflicting approximately 10% of the general population and is a leading cause of disability worldwide, yet our understanding of the basis mechanisms of migraine remains incomplete. About a third of migraine patients have attacks with aura, consisting of transient neurological symptoms that precede or accompany headache, or occur without headache. For patients, aura symptoms are alarming and may be transiently disabling. For clinicians and scientists, aura represents an intriguing neurophysiological event that may provide important insight into basic mechanisms of migraine. Several observations point toward important differences between migraine with and without aura. Compared with migraine without aura, migraine with aura has different heritability, greater association with different conditions including stroke, different alterations of brain structure and function as revealed by imaging studies. A number of studies also indicate that migraine with aura may respond differently to acute and preventive therapies as compared to migraine without aura. The purpose of this review is to provide an overview of these differences in treatment responses, and to discuss the possibility of different therapeutic strategies for migraine with vs. without aura.

Abstract
Headache is a prominent feature in mitochondrial disorders (MIDs) but no comprehensive overview is currently available. This review aims at summarising and discussing findings concerning type, frequency, pathogenesis, and treatment of headache in MIDs. The most frequent headache types in MIDs are migraine and migraine-like headache (MLH). MLH is classified as secondary headache. More rarely, tension-type headache, trigemino-autonomic headache, or different secondary headaches can be found. Migraine or MLH may manifest with or without aura. MLH is frequently associated with an ongoing or previous stroke-like episode (SLE) or a seizure but may also occur independently of other neurological features. MLH may be associated with prolonged aura or visual phenomena after headache. Except for MLH, treatment of headache in MIDs is not at variance from other causes of headache. Beyond the broadly accepted subtype-related headache treatment, diet, cofactors, vitamins, and antioxidants may provide a supplementary benefit. Midazolam, l-arginine, or l-citrulline may be beneficial for MLH. The pathogenesis of headache in MIDs largely remains unsolved. However, since migraine and MLH respond both to triptanes, a shared pathomechanism is likely. In conclusion, migraine and MLH are the prominent headache types in MIDs. MLH may or may not be associated with current or previous SLEs. MLH is pathophysiologically different from migraine and requires treatment at variance from that of migraine with aura.

Abstract
Spreading depolarization is assumed to be the mechanism of migraine with aura, which is accompanied by an initial predominant hyperaemic response followed by persistent vasoconstriction. Cerebral blood flow responses are impaired in patients and in experimental animals after spreading depolarization. Understanding the regulation of cortical blood vessels during and after spreading depolarization could help patients with migraine attacks, but our knowledge of these vascular mechanisms is still incomplete. Recent findings show that control of cerebral blood flow does not only occur at the arteriole level but also at capillaries. Pericytes are vascular mural cells that can constrict or relax around capillaries, mediating local cerebral blood flow control. They participate in the constriction observed during brain ischaemia and might be involved the disruption of the microcirculation during spreading depolarization. To further understand the regulation of cerebral blood flow in spreading depolarization, we examined penetrating arterioles and capillaries with respect to vascular branching order, pericyte location and pericyte calcium responses during somatosensory stimulation and spreading depolarization. Mice expressing a red fluorescent indicator and intravenous injections of FITC-dextran were used to visualize pericytes and vessels, respectively, under two-photon microscopy. By engineering a genetically encoded calcium indicator we could record calcium changes in both pericytes around capillaries and vascular smooth muscle cells around arterioles. We show that somatosensory stimulation evoked a decrease in cytosolic calcium in pericytes located on dilating capillaries, up to the second order capillaries. Furthermore, we show that prolonged vasoconstriction following spreading depolarization is strongest in first order capillaries, with a persistent increase in pericyte calcium. We suggest that the persistence of the 'spreading cortical oligaemia' in migraine could be caused by this constriction of cortical capillaries. After spreading depolarization, somatosensory stimulation no longer evoked changes in capillary diameter and pericyte calcium. Thus, calcium changes in pericytes located on first order capillaries may be a key determinant in local blood flow control and a novel vascular mechanism in migraine. We suggest that prevention or treatment of capillary constriction in migraine with aura, which is an independent risk factor for stroke, may be clinically useful.

Abstract
Migraines are generally considered a relatively benign neurological condition. However, research has shown an association between migraines and stroke, and especially between migraine with aura and ischaemic stroke. Patients can also suffer from migrainous infarction, a subset of ischaemic stroke that often occurs in the posterior circulation of younger women. The exact pathogenesis of migrainous infarct is not known, but it is theorised that the duration and local neuronal energy level from cortical spreading depression may be a key factor. Other factors contributing to migrainous infarct may include vascular, inflammatory, endothelial structure, patent foramen ovale, gender, oral contraceptive pill use and smoking. Vasoconstrictors such as the triptan and ergot class are commonly used to treat migraines and may also play a role. Migraine is also shown to be correlated to haemorrhagic stroke, although studies do not demonstrate causation versus association, and further studies are warranted. There are also some rare genetic diseases such as cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy, retinal vasculopathy with cerebral leukodystrophy and others, which can cause both migraines and infarcts. On imaging, many migraineurs are found to have white matter changes similar to those seen in patients with stroke. These may be caused in part by alterations in resting cerebral blood flow and vasoconstrictor use. In treating patients with migraines, it is important to identify and modify any vascular risk factors such as hypertension, smoking, oral contraceptive pill use and lifestyle factors. Further studies will determine if more aggressive treatment of migraines can ultimately lead to fewer strokes in this population.

Abstract
BACKGROUND The primary objective of the present study was to evaluate the efficacy and safety of using acupressure as an adjunctive therapy to sodium valproate (SV) combined with acupressure (ASV) on the prevention of chronic migraine with aura (CMA). METHODS A total of 98 patients with CMA were randomly divided into an intervention group and a control group, with 49 patients in each group. The patients in the intervention group received ASV, while the participants in the control group received SV alone. The primary outcome was measured by the numeric rating scale (NRS). The secondary outcomes including frequency of migraine attacks, the times of using analgesics, and quality of life, measured by the short-form 36 Health Survey Scale (SF-36) score. In addition, adverse events (AEs) were also recorded throughout the trial. The outcomes were measured at the end of the 8-week treatment, and 4-week follow-up. RESULTS After the 8-week treatment and 4-week follow-up, ASV efficacy was not greater than that of SV alone regarding pain relief, as measured using the NRS, and frequency of migraine attacks, consumption of analgesics, and quality of life, as measured using the SF-36. However, ASV can significantly reduce the nausea when compared with SV (P = .04). CONCLUSION The present results indicate that ASV can decrease migraine-related nausea during treatment, but cannot relieve pain or enhance quality of life in patients with CMA.

Abstract
A single pulse of transcranial magnetic stimulation has been shown to be effective for the acute treatment of migraine with and without aura. Here we aimed to investigate the potential mechanisms of action of transcranial magnetic stimulation, using a transcortical approach, in preclinical migraine models. We tested the susceptibility of cortical spreading depression, the experimental correlate of migraine aura, and further evaluated the response of spontaneous and evoked trigeminovascular activity of second order trigemontothalamic and third order thalamocortical neurons in rats. Single pulse transcranial magnetic stimulation significantly inhibited both mechanical and chemically-induced cortical spreading depression when administered immediately post-induction in rats, but not when administered preinduction, and when controlled by a sham stimulation. Additionally transcranial magnetic stimulation significantly inhibited the spontaneous and evoked firing rate of third order thalamocortical projection neurons, but not second order neurons in the trigeminocervical complex, suggesting a potential modulatory effect that may underlie its utility in migraine. In gyrencephalic cat cortices, when administered post-cortical spreading depression, transcranial magnetic stimulation blocked the propagation of cortical spreading depression in two of eight animals. These results are the first to demonstrate that cortical spreading depression can be blocked in vivo using single pulse transcranial magnetic stimulation and further highlight a novel thalamocortical modulatory capacity that may explain the efficacy of magnetic stimulation in the treatment of migraine with and without aura.

Abstract
Occipital nerve stimulation may be effective in treating chronic migraine. Six studies, including three double-blind studies, were performed, with five showing evidence of benefit. However, of the three randomized, controlled trials, none has met a primary endpoint successfully. A separate study suggested a benefit for combined supraorbital and greater occipital nerve stimulation.

Abstract
The migraine is historically one of the most studied primary headaches. There are many studies about migraine aura and its implications. Exists many physiopathological mechanisms that explain the migraine aura. The most studied is the Prolonged Cortical Depression. In spite of aura is a short timed and innocuous phenomena, there are cases that it could be a disabling condition. In this review we discuss the treatment options for pain and aura symptoms in migraine.

Abstract
Exploding head syndrome (EHS) attacks are characterized by the sensation of sudden loud banging noises, and are occasionally accompanied by the sensation of a flash light. Although these attacks in themselves are usually not painful, it is reported that EHS attacks may precede migraines and may be perceived as auras. A 53-year-old woman, with a 40-year history of fulgurating migraines, experienced 2 different types of EHS attacks. During most of the attacks, which were not painful, she heard sounds like someone yelling or cars passing by. Only 1 episode was accompanied with the sensation of a flash light and of sounds similar to those of an electrical short circuit. On the video-polysomnography, video-polysomnography showed 11 EHS attacks occurred during stage N1 and stage N2; these attacks were preceded by soft snoring. She also had moderate obstructive sleep apnea syndrome (Apnea Hypopnea Index: 16.7) for which an oral appliance was prescribed; the EHS attacks did not recur after this treatment. The pathophysiology of EHS is still unclear. A detailed analysis of PSG data may help in understanding the pathophysiology of this syndrome and also in the selection of therapeutic strategies.

Abstract
Hemiplegic migraine is a specific form of migraine with aura including hemiparesis. It is a rare condition of unclear aetiology. The authors present a case of a 14-year-old boy with persistent foramen ovale, suffering from sporadic hemiplegic migraine. The authors broadly describe the symptoms and types of hemiplegic migraine as well as underlining diagnostic and therapeutic difficulties of the attacks. The patient suffered from recurrent severe headaches, vomiting and co-existing focal neurological symptoms, including alternant hemiparesis. On the basis of the history, thorough clinical observation and numerous accessory investigations a diagnosis of sporadic hemiplegic migraine was established. However, the last attack, with prolonged neurological deficits, was treated as a complication of migraine and defined as persistent aura without infarction. The authors also broadly discuss a differential diagnosis, including other stroke-like incidents, vascular diseases, immunological and mitochondrial disorders that mimic the symptoms and clinical course of sporadic hemiplegic migraine.

Abstract
Migraine with aura (MA) is associated with an increased risk of ischemic stroke, especially in young women with vascular risk factors (smoke, contraceptive pill). Patent foramen ovale (PFO) has also been associated with MA. We describe a 41-year-old man, in good health, with MA since 16, familiar history of diabetes, heavy smoker (30 cigarettes/day). Frequency (1-2 attacks/year) and clinical features of migraine have been unchanged since the onset. A few days before our examination he suffered a typical migraine attack. In the following hours, however, the headache became more and more throbbing and the aura symptoms (regressed as usual in 30 min) reappeared and persisted, so he went to an Emergency Department. The CT-scan (without contrast) was normal. The following days he had visual disturbances and spatial disorientation. We found a normal neurological examination and fundus oculi. He referred persisting visual troubles. We prescribed MR + angioMR which confirmed a migrainous infarction and ruled out others pathological conditions. Further tests found out dyslipidemia, hyperhomocysteinemia, impaired glucose tolerance. Transcranial Doppler showed right to left shunting. We also prescribed the screening tests for vasculitis (normal). In our opinion this case highlights the relevance of vascular risk factors in MA complications also in male subjects.

Abstract
BACKGROUND Numerous studies have explored the effectiveness of complementary and alternative medicine in the treatment of migraine but there is no documented investigation of the effectiveness of yoga therapy for migraine management. OBJECTIVES To investigate the effectiveness of holistic approach of yoga therapy for migraine treatment compared to self-care. DESIGN A randomized controlled trial. METHODS Seventy-two patients with migraine without aura were randomly assigned to yoga therapy or self-care group for 3 months. Primary outcomes were headache frequency (headache diary), severity of migraine (0-10 numerical scale) and pain component (McGill pain questionnaire). Secondary outcomes were anxiety and depression (Hospital anxiety depression scale), medication score. RESULTS After adjustment for baseline values, the subjects' complaints related to headache intensity (P < .001), frequency (P < .001), pain rating index (P < .001), affective pain rating index (P < .001), total pain rating index (P < .001), anxiety and depression scores (P < .001), symptomatic medication use (P < .001) were significantly lower in the yoga group compared to the self-care group. CONCLUSION The study demonstrated a significant reduction in migraine headache frequency and associated clinical features, in patients treated with yoga over a period of 3 months. Further study of this therapeutic intervention appears to be warranted.

Abstract
Familial hemiplegic migraine (FHM) is a rare and genetically heterogeneous autosomal dominant subtype of migraine with aura. Mutations in the genes CACNA1A and SCNA1A, encoding the pore-forming alpha(1) subunits of the neuronal voltage-gated Ca2+ channels Ca(V)2.1 and Na+ channels Na(V)1.1, are responsible for FHM1 and FHM3, respectively, whereas mutations in ATP1A2, encoding the alpha2 subunit of the Na+, K+ adenosinetriphosphatase (ATPase), are responsible for FHM2. This review discusses the functional studies of two FHM1 knockin mice and of several FHM mutants in heterologous expression systems (12 FHM1, 8 FHM2, and 1 FHM3). These studies show the following: (1) FHM1 mutations produce gain-of-function of the Ca(V)2.1 channel and, as a consequence, increased Ca(V)2.1-dependent neurotransmitter release from cortical neurons and facilitation of in vivo induction and propagation of cortical spreading depression (CSD: the phenomenon underlying migraine aura); (2) FHM2 mutations produce loss-of-function of the alpha2 Na+,K+-ATPase; and (3) the FHM3 mutation accelerates recovery from fast inactivation of Na(V)1.5 (and presumably Na(V)1.1) channels. These findings are consistent with the hypothesis that FHM mutations share the ability of rendering the brain more susceptible to CSD by causing either excessive synaptic glutamate release (FHM1) or decreased removal of K+ and glutamate from the synaptic cleft (FHM2) or excessive extracellular K+ (FHM3). The FHM data support a key role of CSD in migraine pathogenesis and point to cortical hyperexcitability as the basis for vulnerability to CSD and to migraine attacks. Hence, they support novel therapeutic strategies that consider CSD and cortical hyperexcitability as key targets for preventive migraine treatment.

Abstract
Migraine therapy consists of two elements, prophylaxis and abortive treatment, for each of which both drug and nondrug strategies are available. To stop mild migraine attacks, analgesics and antiemetics are employed; for severe attacks, triptans are necessary. Triptans differ in their efficacy, tolerance, speed of onset of effect and duration of effect. Moreover, there are different pharmaceutical forms. Triptans are contraindicated for coronary, cerebral and peripheral vascular diseases and, likewise, during pregnancy. They are not suitable for emergency treatment.

Abstract
Hemiplegic migraine is a rare subtype of migraine with aura associated with transient hemiplegia. The weakness is caused by motor aura. Hemiplegic migraine is the only headache syndrome associated with known genetic mutations and serves as a model for understanding more common varieties of migraine. Because the phenotype includes striking yet transient neurological signs and symptoms, it is imperative that clinicians know the differential diagnosis to rule out possible secondary etiologies when treating patients with hemiplegic spells. Hemiplegic migraine occurs with equal prevalence in either a sporadic or familial form differentiated only by family history. Thus far, treatment trials are anecdotal, although verapamil and acetazolamide have shown promise.

Abstract
Migraine is defined as a primary headache; however, some reports may suggest a relationship with dental occlusion and dental parafunction (clenching or grinding of the teeth). A patient diagnosed with migraine with aura, with concomitant temporomandibular joint and masseter muscle pain, was treated by the use of a dental appliance. The treatment succeeded in eliminating headache and visual aura, and significantly reducing the other symptoms. A headache related to dental occlusion and dental parafunctions seems to be able to mimic a primary migraine headache. Therefore, dental evaluation is always advised for headache diagnosis.

Abstract
Migraine aura without headache should be considered as a diagnosis in anyone who has recurrent episodes of transient symptoms, especially those that are visual or neurological or involve vertigo. Visual and neurological symptoms due to migraine are not unusual and most commonly occur in older persons with a history of migraine headaches. Migraine aura without headache should be diagnosed only when transient ischemic attack and seizure disorders have been excluded.

Abstract
Migraine with aura (MwA) sufferers, at times, need specific treatments. This is the case when the auras are frequent, prolonged and cause anxiety and distress. Abnormal release of glutamate, that may trigger auras, and abnormal platelet behaviour, that constitute a possible predisposing factor to MwA, may be possible targets for MwA specific prophylactic therapy. Here we present results obtained by using lamotrigine, an agent known to inhibit glutamate release, and picotamide, an antiplatelet drug. Both drugs significantly reduced, in two open label trials, the frequency and the duration of auras. In comparison with lamotrigine, the therapy with picotamide may offer some advantages, such as the use of the therapeutical dose from the first day of treatment (lamotrigine needs one month to reach such a dose) and the possibility to prevent cerebral ischaemic events and migraine stroke, a rare but severe complication of MwA attacks.

Abstract
Basilar-type migraine (BTM) is a type of migraine with aura symptoms resulting from brain stem or bi-hemispheric structures but without motor elements. There are no precise data on the frequency of BTM. The main cohort of the patients includes young people and children with female predomination. The onset of the disease usually occurs before the age of 25. The diagnosis of BTM is based on the finding of two migraine attacks accompanied by a specific aura, with dysarthria, vertigo, tinnitus, impaired hearing, double vision, visual aura elements, ataxia of a cerebellar type, loss of consciousness, and bilateral paresthesias. In the differential diagnosis one should consider the pathology of posterior fossa, diseases with recurrent vertigo, complex epileptic seizures, CADASIL and MELAS syndromes, and alternative hemiplegic migraine with cerebellar symptoms and signs. In the prophylaxis sodium valproate and calcium-entry blockers and, especially in the prophylaxis of vertigo, betahistine chloride are used.

Abstract
Hemiplegic migraine may be familial or sporadic. Both forms share a similar spectrum of clinical presentations and genetic heterogeneity. Current data support the concept that sporadic and familial cases should be thought of as similar, but separate disorders. Sporadic cases are more difficult to diagnose and often require several investigations to rule out more ominous possibilities. Therapeutic options are limited, but future genetic research may elucidate pathophysiologic mechanisms that may, in turn, yield more specific treatments.

Abstract
UNLABELLED A 14-y-old girl presented with a 2 h history of left hemiplegia preceded by mild left-sided sensory disturbance. She had experienced migraines for several years and there was a strong family history of migraine, including hemiplegic migraine in one of her sisters. Her hemiplegia and headache responded to sumatriptan but her headache and vomiting subsequently returned. She was found to have intracranial hypertension and developed papilloedema and paracentral scotomas. Further history revealed she had been taking minocycline for acne. CONCLUSION An association between hemiplegic migraine and pseudotumour cerebri has not previously been reported. There may be a case for examining patients with pseudotumour cerebri for the calcium channel mutation (CACNA1A).

Abstract
A double-masked randomized controlled study with cross-over design compared the effectiveness of precision ophthalmic tints in the prevention of headache in migraine sufferers. Seventeen patients chose the colour of light that optimally reduced perceptual distortion of text and maximized clarity and comfort. They were later given glasses with spectral filters providing optimal colour under conventional white lighting ('optimal' tint) or glasses that provided a slightly different colour ('control' tint). The tints were supplied in random order, each for 6 weeks, separated by an interval of at least 2 weeks with no tints. Headache diaries showed that the frequency of headaches was marginally lower when the 'optimal' tint was worn, compared with the 'control'. The trial extends to adults with migraine, the results of a previous double-masked study demonstrating, in children with reading difficulty, beneficial effects of precision tints in reducing symptom frequency. In the present study, however, the effects are suggestive rather than conclusive.

Abstract
Users of a commercial light therapy device who were using it to treat migraine were surveyed prospectively to determine what results they obtained after 30 days of daily use. Out of a total of 55 migraineurs, 44% reported that the frequency of their migraine attacks after the treatment was 'Somewhat Less' or 'Much Less' (under a conservative interpretation of these categories). Considering only the 28 migraineurs who stated that their migraine attacks were normally preceded by warning signs, 53% reported that the frequency of their migraine attacks was 'Somewhat Less' or 'Much Less'. In view of the limited efficacy and undesirable side-effects of the available migraine preventive drugs, photic stimulation (flickering light therapy) must be considered a possible preventive treatment for migraine.

Abstract
BACKGROUND Migraine aura without headache (MAWOH) is a type of migraine that seems to be reported more frequently in ophthalmic than neurologic or general medical practice. The clinical characteristics of this condition are described relative to its relationship with other forms of migraine, patient age, gender distribution, laterality, personal or family history, visual aura, and precipitating factors. As a result of its prevalence, it is a condition with which every optometrist and ophthalmologist should be familiar. Since MAWOH is a common cause of photopsia and transient vision loss, it is also important to consider it in the differential diagnosis of these conditions-especially in older patients. METHODS The clinical investigations of MAWOH by prospective and retrospective case series are reviewed. This review includes an analysis by study of the number of patients, migraine history, and type of visual symptom. Comparison of clinical characteristics is used to distinguish MAWOH from other types of migraine. CONCLUSION Migraine aura without headache is a type of migraine that is reported frequently in ophthalmic practice. Because it is related to photopsia and/or transient vision loss, specific clinical procedures should be performed to assist in the differential diagnosis of these conditions.
