Abstract
Introduction: The aim of this review article was to analyze in details the mechanism of drugs’ effects in the treatment and prevention of a migraine attack, as well as to discuss the hypotheses of migraine pathogenesis.
Migraine attack treatment agents: The main agents for migraine attack treatment have an anti-nociceptive activity.
Agents for migraine preventive treatment: β-blocker propranolol also has anti-serotonin and analgesic activities, and most drugs used for the prophylactic treatment of migraine have a vasodilating activity.
Vascular hypothesis of migraine pathogenesis: Despite numerous studies that have expanded our understanding of migraine pathogenesis, the importance of the vascular component in the pathogenesis of this disease has not questioned yet.
Neurogenic hypotheses of cortical spreading depression: It is necessary to take into account the points of this hypothesis in the context of the pathophysiology of migraine.
Neurochemical serotonin hypotheses of migraine pathogenesis: Serotonin plays an important role in the pathogenesis of migraine.
Trigemino-vascular hypotheses of migraine pathogenesis: The trigemino-vascular hypothesis claims to solve the problem of migraine pain.
Migraine and ischemic brain damage: Migraine is a risk factor for ischemic stroke and cognitive disorders.
Search for the new anti-ischemic anti-migraine preparations: A methodology for the search for new anti-ischemic anti-serotonin drugs for the treatment of migraine is proposed.
Conclusion: Belonging of a drug to one or another pharmacological group does not always correspond to its therapeutic effect on the pathogenetic processes of migraine. Migraine with its variety of forms cannot fit only one of the proposed hypotheses on the pathogenesis of this disease.

Abstract
Vascular changes during spontaneous headache attacks have been studied over the last 30 years. The interest in cerebral vessels in headache research was initially due to the hypothesis of cerebral vessels as the pain source. Here, we review the knowledge gained by measuring the cerebral vasculature during spontaneous primary headache attacks with the use of single photon emission tomography (SPECT), positron emission tomography (PET), magnetic resonance imaging (MRA) and transcranial Doppler (TCD). Furthermore, the use of near-infrared spectroscopy in headache research is reviewed. Existing TCD studies of migraine and other headache disorders do not provide solid evidence for cerebral blood flow velocity changes during spontaneous attacks of migraine headache. SPECT studies have clearly shown cortical vascular changes following migraine aura and the differences between migraine with aura compared to migraine without aura. PET studies have shown focal activation in brain structures related to headache, but whether the changes are specific to different primary headaches have yet to be demonstrated. MR angiography has shown precise changes in large cerebral vessels during spontaneous migraine without aura attacks. Future development in more precise imaging methods may further elucidate the pathophysiological mechanisms in primary headaches.

Abstract
Headache is one of the most common ailments; migraine is one of the most prevalent and disabling neurological disorders and cluster headache presents as one of the most excruciating pain disorders. Both are complex disorder characterized by recurrent episodes of headache. A key feature is that various triggers can set off an attack providing the opportunity to explore disease mechanisms by experimentally inducing attacks. This review summarizes neuroimaging and hemodynamic studies in human in provoked and spontaneous attacks of migraine and cluster headache. Cerebral hemodynamics during different phases of the migraine attack demonstrate alterations in cerebral blood flow and perfusion, vessel caliber, cortical and sub-cortical function, underscoring that migraine pathophysiology is highly complex. Migraine attacks might begin in diencephalic and brainstem areas, whereas migraine aura is a cortical phenomenon. In cluster headache pathophysiology, the hypothalamus might also play a pivotal role, whereas the pattern of cerebral blood flood differs from migraine. For both disorders, alterations of arterial blood vessel diameter might be more an epiphenomenon of the attack than a causative trigger. Studying cerebral hemodynamics in provocation models are important in the search for specific biomarkers in the hope to discover future targets for more specific and effective mechanism-based anti-headache treatment.

Abstract
Spreading depression (SD) is a transient wave of near-complete neuronal and glial depolarization associated with massive transmembrane ionic and water shifts. It is evolutionarily conserved in the central nervous systems of a wide variety of species from locust to human. The depolarization spreads slowly at a rate of only millimeters per minute by way of grey matter contiguity, irrespective of functional or vascular divisions, and lasts up to a minute in otherwise normal tissue. As such, SD is a radically different breed of electrophysiological activity compared with everyday neural activity, such as action potentials and synaptic transmission. Seventy years after its discovery by Leão, the mechanisms of SD and its profound metabolic and hemodynamic effects are still debated. What we did learn of consequence, however, is that SD plays a central role in the pathophysiology of a number of diseases including migraine, ischemic stroke, intracranial hemorrhage, and traumatic brain injury. An intriguing overlap among them is that they are all neurovascular disorders. Therefore, the interplay between neurons and vascular elements is critical for our understanding of the impact of this homeostatic breakdown in patients. The challenges of translating experimental data into human pathophysiology notwithstanding, this review provides a detailed account of bidirectional interactions between brain parenchyma and the cerebral vasculature during SD and puts this in the context of neurovascular diseases.

Abstract
Until recently, primary headache disorders, such as migraine and cluster headache were considered to be vascular in origin. However, advances in neuroimaging techniques, such as positron emission tomography, single photon emission computed tomography and functional magnetic resonance imaging have augmented the growing clinical evidence that these headaches are primarily driven from the brain. This review covers functional imaging studies in migraine, cluster headache, rarer headache syndromes and experimental head pain. Together with newer techniques, such as voxel-based morphometry and magnetic resonance spectrometry, functional imaging continues to play a role in elucidating and targeting the neural substrates in each of the primary headache syndromes.

Abstract
The cerebral cortex serves a primary role in the pathogenesis of migraine. This aberrant brain activation in migraine can be noninvasively detected with magnetoencephalography (MEG). The objective of this study was to investigate the differences in motor cortical activation between attacks (ictal) and pain free intervals (interictal) in children and adolescents with migraine using both low- and high-frequency neuromagnetic signals. Thirty subjects with an acute migraine and 30 subjects with a history of migraine, while pain free, were compared to age- and gender-matched controls using MEG. Motor cortical activation was elicited by a standardized, validated finger-tapping task. Low-frequency brain activation (1∼50 Hz) was analyzed with waveform measurements and high-frequency oscillations (65–150 Hz) were analyzed with wavelet-based beamforming. MEG waveforms showed that the ictal latency of low-frequency brain activation was significantly delayed as compared with controls, while the interictal latency of brain activation was similar to that of controls. The ictal amplitude of low-frequency brain activation was significantly increased as compared with controls, while the interictal amplitude of brain activation was similar to that of controls. The ictal source power of high-frequency oscillations was significantly stronger than that of the controls, while the interictal source power of high-frequency oscillations was significantly weaker than that of controls. The results suggest that aberrant low-frequency brain activation in migraine during a headache attack returned to normal interictally. However, high-frequency oscillations changed from ictal hyper-activation to interictal hypo-activation. Noninvasive assessment of cortical abnormality in migraine with MEG opens a new window for developing novel therapeutic strategies for childhood migraine by maintaining a balanced cortical excitability.

Abstract
Background Hemiplegic migraine is a rare form of migraine with aura that includes motor weakness. Diagnosis during the first episode can be difficult to make and costly, especially with the sporadic form. Cases Our study evaluates the ictal magnetic resonance imaging (MRI) features of four sequential pediatric patients during a first-time, sporadic hemiplegic migraine. Susceptibility-weighted imaging (SWI) revealed cerebral venous prominence and increased magnetic susceptibility affecting brain regions that corresponded with each patient’s neurologic deficits. Repeat MRI (performed in three patients) following migraine recovery demonstrated resolution of all susceptibility abnormalities. Conclusion When combined with conventional MRI sequences, SWI has diagnostic value in the acute setting of motor weakness and with clinical features consistent with hemiplegic migraine. The sequence may help to further characterize ictal cerebral blood flow changes during the hemiplegic migraine aura.

Abstract
We encountered a patient with the overlapping disorders of migraine with aura, migraine-triggered seizures and recurrent transient hemiparesis caused by atypical hemiplegic migraines with motor weakness during headache attacks, but not during the aura period, or paradoxical cerebral embolism. The patient displayed a giant Eustachian valve and patent foramen ovale, through which a spontaneous right-to-left shunt was revealed on transesophageal echocardiography. We considered that the overlapping disorders in the present case were closely related to the spontaneous right-to-left shunt caused by the giant Eustachian valve.

Abstract
BACKGROUND The pathophysiological alterations in patients with familial hemiplegic migraine (FHM) are not yet fully known. The headache characteristics in patients with FHM mutations have been examined in a series of glyceryl trinitrate (GTN) provocation studies in FHM patients, but the cortical vascular response to GTN in FHM patients has never been investigated before. OBJECTIVE To investigate changes in spontaneous low-frequency oscillations (LFO) of cortical vessels in response to the nitric oxide donor GTN by near-infrared spectroscopy in FHM patients. METHODS Twenty-three FHM patients without known mutations and 9 healthy controls received a continuous intravenous infusion of GTN 0.5 µg/kg/minute over 20 minutes. Using near-infrared spectroscopy, we recorded oxygenated hemoglobin (oxyHb) LFO amplitude bilateral at the frontal cortex at baseline and 15 minutes and 40 minutes after start of the GTN infusion. RESULTS GTN changed oxyHb LFO amplitude in FHM patients (P = .002), but not in healthy controls (P = .121). Only in FHM patients with coexisting common migraine types did GTN infusion induced changes in LFO amplitudes (P < .001), where post-hoc analysis revealed an increase in LFO amplitude 15 minutes (P = .003) and 40 (P = .013) minutes after start of infusion compared with baseline. Interestingly, GTN infusion induced no changes in LFO amplitude in patients with a pure FHM phenotype (P = .695). CONCLUSION FHM patients with a mixed phenotype (coexisting common type of migraine) showed an increase in oxyHb LFO amplitude during GTN infusion, whereas FHM patients with pure phenotype showed no changes. These data suggest possible differences in frontal cortical nitric oxide vascular sensitivity between FHM patients with a mixed phenotype and patients with pure FHM.

Abstract
Several personal descriptions of migraine with aura from 1870 onwards reported a slow, gradual progression of symptoms. Lashley in 1941 meticulously chartered his own auras and concluded that the symptomatology reflected a cortical process progressing with a speed of 3 mm/min across the primary visual cortex. Leão described cortical spreading depression (CSD) in rabbits in 1944 and noticed its similarity to the migraine aura. Despite these scattered pieces of evidence, the prevailing theory was that the migraine aura was caused by a vasospasm and cortical ischaemia. The advent of a technique for measurements of regional cerebral blood flow (rCBF) in 1974 made it possible to detect spreading oligaemia during migraine aura. Between 1981 and 1990 a series of studies of rCBF during migraine attacks showed reduced brain blood flow posteriorly spreading slowly and contiguously anteriorly and crossing borders of supply of major cerebral arteries. These observations refuted the ischaemic hypothesis. The human studies showed initial hyperaemia followed by prolonged hypoperfusion. The relation between aura and CSD was known to cause short-lasting, and therefore not obvious vasodilation and it was considerably strengthened by the demonstration of a long-lasting oligaemia in rats in the wake of CSD. In the primates CSD is not easily elicited, but it has in recent years been clearly demonstrated in patients with brain trauma and stroke. Finally, mutations for familial hemiplegic migraine have been expressed in mice and lower the threshold for CSD. The seminal papers on rCBF and CSD published in the 1980s caused a dramatic shift in our concepts of migraine aura. They moved attention from ischaemia to CSD and thereby to the brain itself, and paved the way for subsequent discoveries of brainstem mechanisms.

Abstract
Introduction: Calcitonin gene-related peptide (CGRP) is a key molecule in migraine pathogenesis. Intravenous CGRP infusion triggers delayed migraine-like attacks in patients with migraine without aura (MO). In contrast to patients with MO, in prior studies patients with familial hemiplegic migraine (FHM) did not report more migraine-like attacks compared to controls. Whether CGRP triggers migraine in patients with typical (non-hemiplegic) migraine with aura is (MA) unknown. In the present study we examined the migraine inducing effect of CGRP infusion in patients suffering from MA and healthy controls. Methods: Fourteen patients suffering exclusively from migraine with typical aura (MA) and 11 healthy volunteers received a continuous intravenous infusion of 1.5 µg/min CGRP over 20 minutes. Headache and other migraine symptoms were scored every 10 minutes for one hour and self recorded hourly thereafter and until 13 hours post-infusion. Results: CGRP infusion induced significantly more delayed headaches in MA patients (12 out of 14) than in controls (2 out of 11) ( p = 0.001). Furthermore, significantly more MA patients (57%; 8 out of 14) fulfilled criteria for an experimentally induced migraine attack after CGRP than controls (0%; 0 out of 11) ( P = 0.003). Four patients (28%) reported aura symptoms after CGRP infusion. Conclusion: CGRP triggered migraine-like attacks without aura in patients suffering exclusively from MA. It also triggered a typical aura in 28% of the patients. These data indicate similar neurobiological pathways responsible for triggering migraine headache in MA and MO patients, and suggest differences between MA/MO and FHM.

Abstract
OBJECTIVE Patent foramen ovale and pulmonary arteriovenous shunts are associated with serious complications such as cerebral emboli, stroke, and migraine with aura. The pathophysiological mechanisms that link these conditions are unknown. We aimed to establish a mechanism linking microembolization to migraine aura in an experimental animal model. METHODS We introduced particulate or air microemboli into the carotid circulation in mice to determine whether transient microvascular occlusion, insufficient to cause infarcts, triggered cortical spreading depression (CSD), a propagating slow depolarization that underlies migraine aura. RESULTS Air microemboli reliably triggered CSD without causing infarction. Polystyrene microspheres (10 microm) or cholesterol crystals (<70 microm) triggered CSD in 16 of 28 mice, with 60% of the mice (40% of those with CSD) showing no infarcts or inflammation on detailed histological analysis of serial brain sections. No evidence of injury was detected on magnetic resonance imaging examination (9.4T; T2 weighted) in 14 of 15 selected animals. The occurrence of CSD appeared to be related to the magnitude and duration of flow reduction, with a triggering mechanism that depended on decreased brain perfusion but not sustained tissue damage. INTERPRETATION In a mouse model, microemboli triggered CSD, often without causing microinfarction. Paradoxical embolization then may link cardiac and extracardiac right-to-left shunts to migraine aura. If translatable to humans, a subset of migraine auras may belong to a spectrum of hypoperfusion disorders along with transient ischemic attacks and silent infarcts.

Abstract
OBJECTIVE The objective of this study is to present a view of the primary headaches as genetically determined behavioral responses consistent with sickness behavior and defense reaction, respectively. BACKGROUND AND DESIGN A review of the literature bearing on the behavioral, humoral, and functional imaging aspects of the primary headaches shows that migraine and cluster headache (CH) are pain conditions characterized by different behaviors during the attacks. Here it is postulated that the behavioral responses to migraine and CH are evolutionary conserved reactions consistent with sickness behavior and defense reaction. RESULTS The sickness behavior observed during migraine attacks is a pan-mammalian adaptive response to internal and external stressors, characterized by withdrawal and motor quiescence, sympatho-inhibition and lethargy, in which visceral pain signals a homeostatic imbalance of the body and/or brain. In contrast, the defense reaction in CH consists of a fight-or-flight reaction, with motor restlessness and agitation, in which pain is exteroceptive in kind. CONCLUSION These different behavioral responses are thus specific to different kinds of pain, distinguished by the behavioral significance of the pain (visceral pain in migraine vs exteroceptive pain in CH), and imply brain matrices involving different networks in the brainstem, hypothalamus, and forebrain regions that engender evolutionarily conserved adaptive genetic responses. Cytokines play an important role in their development. Predictions and limitations of the hypothesis are discussed together with implications for genetic studies on headaches.

Familial hemiplegic migraine type 1 (FHM-1) is a dominantly inherited subtype of migraine with aura and transient hemiplegia associated with mutations in the CACNA1A gene. FHM-1 shares many phenotypical similarities with common types of migraine, indicating common neurobiological pathways. Experimental studies have established that activation of the nitric oxide-cyclic guanosine monophosphate (NO-cGMP) pathway plays a crucial role in migraine pathophysiology. Therefore, we tested the hypothesis that CACNA1A mutations in patients with FHM-1 are associated with hypersensitivity to NO-cGMP pathway. We included eight FHM-1 patients with R583Q and C1369Y mutations and nine healthy controls, who received intravenous infusions of 0.5 microg kg(-1) min(-1) glyceryl trinitrate (GTN) over 20 min. We recorded: headache intensity on a verbal rating scale; mean flow velocity in the middle cerebral artery (V(meanMCA)) by transcranial Doppler; diameter of the superficial temporal artery (STA) by Dermascan. One patient reported migraine without aura 5 h after start of the GTN infusion. No aura was reported. The AUC(headache) in the immediate phase was more pronounced in patients than in controls (P = 0.01). In the 14 h following GTN infusion, there was no difference in the AUC(headache) between patients and controls (P = 0.17). We found no difference in the AUC(VmeanMCA) (P = 0.12) or AUC(STA) (P = 0.71) between FHM-1 patients and controls. None of the control persons reported migraine-like headache. FHM-1 patients do not show hypersensitivity of the NO-cGMP pathway, as characteristically seen in migraine patients with and without aura. This indicates that the pathophysiological pathways underlying migraine headache in FHM-1 may be different from the common types of migraine.

Abstract
Increasingly sophisticated neuroimaging techniques have allowed researchers to begin to define functional and anatomical characteristics of migraine. This paper reviews current knowledge and techniques employed. Assessing present-day knowledge limitations it concludes that with parallel advances in the technology of imaging and the pathophysiologic understanding of migraine, a reliable biomarker may be discovered in the future.

Abstract
Until recently, primary headache disorders such as migraine and cluster headache were considered to be vascular in origin. However, advances in neuroimaging techniques, such as positron emission tomography, single photon emission computerized tomography, and functional magnetic resonance imaging, have augmented the growing clinical evidence that these headaches are primarily driven from the brain. This review covers functional imaging studies in migraine, cluster headache, rarer headache syndromes, and experimental head pain. Together with newer techniques, such as voxel-based morphometry and magnetic resonance spectrometry, functional imaging continues to play a role in elucidating and targeting the neural substrates in each of the primary headache syndromes.

Abstract
OBJECTIVE To explore the association between migraine and risk of ischaemic stroke. DESIGN Systematic review and meta-analysis. DATA SOURCES Observational studies published between 1966 and June 2004 (identified through Medline and Embase) that examined the association between migraine and risk of ischaemic stroke. RESULTS 14 studies (11 case-control studies and 3 cohort studies) were identified. These studies suggest that the risk of stroke is increased in people with migraine (relative risk 2.16, 95% confidence interval 1.89 to 2.48). This increase in risk was consistent in people who had migraine with aura (relative risk 2.27, 1.61 to 3.19) and migraine without aura (relative risk 1.83, 1.06 to 3.15), as well as in those taking oral contraceptives (relative risk 8.72, 5.05 to 15.05). CONCLUSIONS Data from observational studies suggest that migraine may be a risk factor in developing stroke. More studies are needed to explore the mechanism of this potential association. In addition, the risk of migraine among users of oral contraceptives must be further investigated.

Abstract
Migraine is episodic, paroxysmal disorder where the headache represents the central symptom and is followed with different combinations of neurologic, gastrointestinal and vegetative changes. Not until the diagnostic procedures were developed, ischemic lesions were verified even in the patients with ordinary migraine. This is a report of a patient with migraine headache, followed twice by verified episodes of temporary ischemic attacks and verified focal ischemic lesion of cerebral parenchyma. The mitral valve prolapse was also detected. This all imposed the administration of combined prophylactic antimigrainous and anticoagulant therapy as an imperative because of the risk of the development of repeated ischemia of cerebral tissue. This association also confirmed an opinion that migraine is a wider disorder with the dominant dysfunction of limbic system.

Abstract
Eleven cases of migraine with and without aura were investigated with positron emission tomography (PET). Regional cerebral blood flow (rCBF), oxygen metabolism (rCMRO2) and oxygen extraction (rOER) were measured during baseline (n = 11), aura (n = 6), headache (n = 10) and after treatment with sumatriptan (n = 4). Data were analysed using an ROI-based approach from 26 different anatomically defined regions, and also an exploratory approach whereby all subjects were normalized to a stereotactic brain atlas; t-maps were constructed by depicting significant changes between states. The exploratory approach revealed a region corresponding to the primary visual cortex with significant reductions in rCBF (23.1%) and rCMRO2 (22.5%), but no change in rOER during the headache phase compared to baseline. These data suggest that cerebral ischemia was not the primary cause of the attacks in these cases.

Abstract
Diffusion weighted imaging (DWI) and T2 weighted magnetic resonance imaging were performed on at least two occasions in 28 children presenting with stroke. In previous reports of DWI in human stroke, eventual infarction was observed (with only one exception) in all regions in which early DWI hyperintensity occurred. In the present report, two children had regions of DWI hyperintensity which did not progress to infarction. One patient who presented with right hemiplegia showed extensive high signal on DWI, with T2 evidence of tissue swelling but without hyperintensity. DWI changes persisted over weeks, with no imaging indication of infarction. This child recovered completely. A second child who had a major vessel infarct with concomitant regions of hyperintensity on T2 weighted imaging and DWI, also had DWI hyperintensity in an adjacent territory which did not develop any subsequent evidence of infarction. Thus in clinical practice DWI can demonstrate tissue which is compromised but not irreversibly so.

Abstract
Alterations of intracranial vessel tone have been implicated in the pathophysiology of migraine. The cerebrovascular reactivity was measured by means of transcranial Doppler in 60 migraine patients with (n = 30) or without aura (n = 30) during the headache-free interval and in 30 healthy controls. The vasomotor response was evaluated during hypercapnia induced by inhalation of a mixture of CO2 5% and O2 95% and during hypocapnia obtained after voluntary hyperventilation. To improve the power of the study in detecting possible abnormalities of cerebrovascular reactivity, two different measures were performed at 1 week intervals in migraine patients and controls. Reactivity index values during CO2 inhalation were significantly different (p = 0.01) among the three groups during the first and second measurements; in particular, lower values were found in patients suffering from migraine without aura with respect to controls (p < 0.05, Scheffé's test). Values of reactivity index obtained following induction of hypocapnia did not differ between migraine patients and controls (all p values > 0.05). Our data suggest a reduced vasodilatory response to hypercapnia of cerebral arterioles in patients suffering from migraine without aura with respect to controls that might be related to baseline arteriolar vasodilation.

Abstract
Since migraine attacks are often frequent they require management with agents that reduce their number. Such agents, although often effective, are mechanistically ill-understood. They have been suggested to work through four main mechanisms, 5HT2 antagonism, modulation of plasma protein extravasation, modulation of central aminergic control mechanisms and membrane stabilizing effects through actions at voltage-sensitive channels. The evidence for these mechanisms, except plasma protein extravasation (see Cutrer, this supplement) is examined in the light of current thoughts concerning the pathophysiology of migraine.

Abstract
An understanding of the basic anatomy and physiology of the cranial circulation facilitates the assessment and management of patients with headache, particularly vascular-type headaches, such as migraine. At the very least, all pain is perceived and processed in the brain. With migraine it is likely that the fundamental problem and its clinical expression are driven by the CNS; thus study of the brain regarding headache is warranted. As therapy evolves during the 1900s, such an understanding will be necessary, as new and highly specific receptor-targeted compounds allow treatment and improvement of headache in many patients. Since writing this article, the nomenclature for serotonin (5HT) receptors has changed so that any reference herein to 5HTID alpha is now 5HTID and 5HTID beta is now 5HTI beta. This change in nomenclature is discussed in Martig PR, Hoyer D, Humphrey PPA, et al: Alignment of receptor nomenclature with the human genome: Classification of 5HT-1 beta and 5HT-1D receptor subtypes. Trends in the Pharmacological Sciences 17:103, 1996.

Abstract
The changes in cerebral blood flow that accompany spreading depression are well-described, as are parallel changes in cellular activity, with a wave of hyperemia followed by a prolonged oligemic phase. In this study, a cat model of the CBF changes associated with spreading depression and in vitro pharmacology were used to determine if there is a role for the powerful peptide vasoconstrictor endothelin in this response. For the pharmacological studies, the middle cerebral artery was harvested from cats postmortem. For the physiological studies, cats were anesthetized with halothane induction and alpha-chloralose (60 mg/kg, intraperitoneal loading; 20 mg/kg i.v. 2-h maintenance). CBF was monitored continuously in the parietal cortex using laser Doppler flowmetry (CBFLDF) after exposure of the dura mater. The in vitro work demonstrated that endothelin-1 (ET-1) mediates a strong and potent contraction of cerebral vessels. Both the selective ETA receptor antagonist FR139317 and the combined ETA and ETB receptor antagonist Bosentan caused a rightward shift of the concentration-response curve without attenuation of the maximum effect. The calculated pA2 values were 6.28 and 6.90, respectively. The slope did not differ from unity, suggesting that the ET-1-mediated contraction is evoked by a single population of ETA receptors, which were effectively antagonized by these compounds. Spreading depression was induced with a needle stick injury to the cortex. Local administration of the endothelin antagonists FR139317 (10 microM) and Bosentan (10 microM) did not affect resting blood flow in the cortex. Induction of spreading depression following local administration of FR139317 and Bosentan resulted in responses no different from those in control cortex. These data demonstrate that endothelin does not play a significant role in the vasoconstrictor portion of the CBF change seen in spreading depression, nor does it affect resting flow. Since it is widely held that spreading depression, or a very similar mechanism, underlies the aura phase of migraine, it may be suggested from these studies that endothelin antagonists are unlikely to be useful in migraine.

Abstract
The authors present the study of four children that manifested asymmetric hemiparesis with sudden onset, without consciousness loss. The diagnosis of striatocapsular infarction was confirmed by computed tomography (CT) and magnetic resonance imaging (MRI). The clinical and neurological examination, and laboratorial results are discussed. Familial history of migraine was found in two of the patients. Migraine was diagnosed in two, mild head trauma, viral miocarditis and mitral valve prolapse in one. Left hemiparesis, with brachiofacial features in three, and brachial in one. CT showed lenticular nucleus and internal capsule lesions in all of them, head of caudate nucleus in three, and white substance in two. MRI was done in two and confirmed CT findings. Electroencephalogram, at the acute phase in three, showed abnormalities in all patients.

Abstract
Information concerning the frequency, severity, character, location, duration, diurnal pattern of headache and ancillary symptoms were obtained in 25 patients with autonomic failure and 44 control subjects. Precipitating and ameliorating factors were identified. Autonomic failure patients had more head and neck discomfort than controls. Their discomfort was much more likely to localize in the occiput, nape of the neck and shoulder, compared with controls. There was a greater tendency for the discomfort to occur in the morning and after meals. It was sometimes less than 5 min in duration and was often associated with dimming, blurring, or tunnelling of vision. It was provoked by upright posture and relieved by lying down. Patients with severe autonomic failure and orthostatic hypotension often present with a posture-dependent headache or neck pain. Because the relationship of these symptoms to posture is often not recognized, the fact that these findings may signal an underlying autonomic disorder is underappreciated, and the opportunity to consider this aetiology for the headache may be missed.

Abstract
BACKGROUND AND PURPOSE The aura phase of migraine is associated with focal blood flow changes, but it has been largely unknown whether these changes are correlated to changes in the cerebral metabolism. METHODS Eight patients required carotid angiography for evaluation of transient neurological attacks. Cerebral blood flow (CBF) results, angiography, and clinical observations subsequently suggested the diagnosis: migraine with aura and occasional aura attacks without headache. In the same setting the cerebral angiography was followed by four to six repeated recordings of regional CBF using the intra-arterial 133Xe injection method. Blood samples were drawn from the carotid artery and the internal jugular vein to measure oxygen extraction fraction and cerebral metabolic rate for oxygen. RESULTS The intracarotid regional CBF technique provoked aura symptoms and typical, migraine-related, posterior focal hypoperfusion in four patients, followed by typical unilateral headache in three patients. The remaining four patients had no symptoms or regional CBF changes during the examination. There was a significant increase (mean, 13%) of global oxygen extraction fraction in the four patients during aura symptoms, whereas no significant changes of oxygen extraction fraction were found in the nonsymptomatic group. The increase in global oxygen extraction fraction in the symptomatic group coincided with a drop of hemispheric CBF (mean, 12%). Cerebral metabolic oxygen rate remained essentially unchanged, as did PaCO2. CONCLUSIONS The data presented suggest that the focal flow reduction during the migraine-aura phase is not a secondary phenomenon of reduced cerebral metabolism. However, arteriolar vasoconstriction might offer a possible explanation for the regional CBF changes observed during the migraine aura.

Abstract
Familial hemiplegic migraine (FHM) is an autosomal dominant type of migraine and probably represents the most extreme end of migraine with aura. Reduced magnesium facilitates the development of spreading depression and possibly aura. Cellular magnesium levels are under genetic control. We hypothesized that FHM patients would have significantly reduced intracellular magnesium levels. We determined intracellular and plasma magnesium levels in blood of 38 afflicted and 11 non-afflicted members of three families with FHM and in 32 migraine patients (9 with and 23 without aura) and 32 age and sex matched healthy controls. We found no significant differences between the magnesium levels in the five study groups. We conclude that reduced blood magnesium is unlikely to be related to migraine pathophysiology.

Abstract
In eight patients carotid angiography was required for evaluation of transient neurological attacks. Cerebral blood flow results, angiography and clinical observations subsequently suggested the diagnosis of migraine. We measured plasma concentrations of substance P(SP), neuropeptide Y (NPY), calcitonin gene-related peptide (CGRP) and vasoactive intestinal peptide (VIP) in repeated blood samples obtained from the carotid artery and the internal jugular vein in conjunction with cerebral angiography followed by 4 to 6 repeated recordings of regional cerebral blood flow (rCBF) with the intracarotid Xenon-133 injection technique. This technique is known to induce attacks of migraine with aura in many sufferers. Four patients developed aura symptoms. In three this was succeeded by throbbing headache. Typical, migraine-related, focal hypoperfusion occurred in conjunction with the aura symptoms. The remaining four patients had no symptoms or rCBF changes. There were no systematic or statistically significant changes over time in arterial-venous plasma concentrations or in the release rates of any of the peptides. All migraineurs had an overall elevated mean CGRP value compared to control values from the literature. The overall plasma levels of the potent vasoconstrictor NPY were higher (p < 0.10) in the group that developed symptoms and rCBF changes (136 pmol/l) than in the non-symptomatic group (97 pmol/l). The difference in NPY levels could perhaps be associated with the focal rCBF decrease seen in the attack group.

Abstract
Migraine patients have chronically low systemic 5-HT, predisposing them to develop migrainous headache once an attack has been initiated. Changes in platelet 5-HT content are not causally related, but reflect similar changes at a neuronal level. Stimulation of vascular 5-HT1 receptors, probably located in the vessel wall within the dural vascular bed, may alleviate the headache and associated symptoms, but does not interact with earlier mechanisms within the pathophysiological cascade. These receptors are of an as yet unidentified 5-HT1 subtype, closely resembling, but not identical to 5-HT1D receptors. Activation of these receptors results in vasoconstriction, inhibiting depolarization of sensory perivascular afferents within the trigemino-vascular system and thus stopping the headache. Additional inhibition of the release of vasoactive neuropeptides may be involved, but seems to be of only secondary clinical importance.

Abstract
Recent reviews on the mode of action of the anti-migraine drug sumatriptan arrived at contrasting conclusions. Whereas some reviewers concluded that vasoconstriction is the most important action, others suggest that neuronal inhibition is essential. Both views were based predominantly on animal or in vitro experiments. In this comment, Michel Ferrari and Pramod Saxena review the experimental effects of sumatriptan in humans and discuss the clinical validity of both theories. In addition, they examine the initial efficacy of treatment and the mechanism of recurrence of headache within 24 hours, which is the most important drawback of sumatriptan in clinical practice, next to its possible cardiac side effects.

Abstract
Eighty subjects--30 migraineurs during the attack, 30 patients in the interictal period, and 20 healthy volunteers--were studied using two technologies for functional assessment: transcranial Doppler ultrasound and magnetoencephalography. Transcranial Doppler studies showed an increased mean flow velocity at rest (p less than 0.05) in the middle cerebral artery on the side of the headache and a decreased vasomotor response to CO 2 (p less than 0.001) on the same side compared to control subjects. Biomagnetic measurements of somatosensory evoked fields of 11 patients and 11 control subjects in this study did not demonstrate differences between migraineurs and the control group in current flow or latency measures. The data from this study tend to support the hypothesis of vascular disease as a primary underlying deficit in migraine.

Abstract
Altered cerebral vasoreactivity (CVR) has been implicated in migraine. To test this hypothesis, we studied CVR as measured by transcranial Doppler ultrasound (TCD) in 11 migraineurs and 12 healthy controls of similar age. Mean flow velocities (MFV) in the middle cerebral artery (MCA) were recorded during a cognitive and two motor tasks. MFV in the posterior cerebral artery (PCA) were measured during photic stimulation and observation of complex images. The increase of MFV in the MCA during the cognitive task was greater in migraineurs than in controls (9.1% vs 5.0%; P = 0.06). The increase of MFV in both tests for PCA reactivity was significantly greater in migraineurs than in controls: 17.4% vs 9.9% for photic stimulation (P less than 0.05) and 20.3% vs 10.2% for observation of complex images (P less than 0.05). Owing to overlap of individual results, the discriminative value of both tests was unsatisfactory. The variability of flow velocities as measured by standard deviations of MFV was significantly greater in migraineurs than in controls during all tests of PCA vasoreactivity. Differences in CVR between migraineurs and normal controls may be detected by TCD testing, in particular in the PCA territory. For individual diagnostic purposes, CVR tests proved to be insufficient.

Abstract
Clinical and neurophysiological observations indicate that the symptoms of migraine aura result from the spread of an excitatory wave along the cortex from a primary focus. This excitation may start as a consequence of information overload on a low threshold cortical area. The transient neuronal excitatory wave is followed by a longer lasting "depressive" wave, which involves a substantial reduction in cortical blood flow (with an active constriction of resistance vessels) and ionic changes and transmitter release into the extracellular fluid compartment. As a consequence, trigeminal pain fibre endings in cortical venules may become activated and, via branches (axon reflexes) along the venous vascular tree, also multiple endings in dural venules. This will induce a neurogenic inflammation in the vessel walls, primarily in dural venules, experienced as headache by the sufferer when sufficiently many fibres have become activated. The pain fibre endings are equipped with serotonin1D-like receptors, which upon stimulation suppress the inflammatory process. This scenario offers a rational explanation for the beneficial effect of the acute, and some of the prophylactic, medications used in migraine.

Abstract
Sumatriptan is a novel, highly effective drug against migraine and cluster headache attacks. It shows a remarkably selective pharmacological profile in animals. Determination of its mechanism of action in human should further the understanding of the pathophysiology of migraine and cluster headache. We, therefore, review current knowledge on the clinical and pharmacological effects of sumatriptan. Important pharmacological actions of sumatriptan are (i) poor penetration of the blood-brain barrier suggesting a peripheral point of action; (ii) 5-HT1-like/5-HT1d receptor-mediated vasoconstriction of large cerebral arteries and dural vessels; and (iii) blockade of neurogenic dural inflammation via 5-HT1d autoreceptor-mediated inhibition of vasoactive neuropeptides within the trigeminovascular system. Future research will tell which mechanism is involved in the pathophysiology of migraine and cluster headache.

Abstract
A vascular-supraspinal-myogenic (VSM) model for pain in migraine based on our previous clinical and pathophysiological observations is proposed. According to the model, perceived pain (headache) intensity is determined by the sum of nociception from cephalic arteries and pericranial myofascial tissues converging upon the same neurons and integrated with supraspinal effects (usually facilitating). Vascular input predominates over myofascial input in migraine, whereas significance of supraspinal facilitation is difficult to estimate. The importance of these 3 effects may vary between patients and in the same individual with time. The model is in accordance with recent experimental studies showing convergence of somatovisceral afferents upon n. caudalis neurons. Also, long term potentiation due to nociceptive activation and sensitization of neurons to input from wider areas and non-nociceptive stimuli are relevant to our model. In tension-type headache, nociception is primarily myofascial, but vascular input cannot be disregarded. Supraspinal facilitation probably plays a large, sometimes dominant role (the MSV model). The model explains much of the complexity of the clinical picture of these disorders as well as their tendency to overlap and to change into one another. Also, a number of pathophysiological observations such as why muscles are tender during migraine, why trigger-point injection may cure migraine attacks and why chronic tension-type headache is often associated with episodes of pulsating pain, can be explained. The model gives a rational explanation of empirically developed, internationally accepted, multimodal treatment strategies for migraine and tension-type headache. It may thus serve a useful purpose in explaining the disorder to patients. Finally, the model points to several avenues of future research in animals and man.

Abstract
The combination of measurements of regional cerebral blood flow (rCBF) and blood velocity in the middle cerebral arteries (MCA) by transcranial doppler sonography was used to investigate cerebrovascular involvement in migraine. Ten migraine patients with unilateral headache were studied during an attack and when they had been free of attacks for 5 days (non-attack). On both occasions they were given as intravenous infusion of sumatriptan (2 mg), a 5-HT1-like receptor agonist, which relieved the symptoms within 30 min without affecting rCBF. The MCA velocity was normal on both sides on the non-attack day and on the unaffected side during the attack. However, during the attack the MCA velocity on the headache side was significantly lower than that on the non-headache side (45 vs 61 cm/s:mean difference 16.3 [95% confidence interval 10.3-22.3]; p = 0.02). The MCA velocity on the headache side returned to normal after treatment with sumatriptan and recovery. Since rCBF in the MCA supply territory was unaffected, the lower velocity can be explained only by dilatation of the MCA. The mean MCA diameter increase was estimated to be 20%. Thus, headache was associated with intracranial large arterial dilatation on the headache side. Sumatriptan predominantly had effects on the distended artery, which suggests that the 5-HT receptor system has a role in the pathogenesis of migraine.

Abstract
A number of basically different methods have been used in studies of the cerebrovascular changes which occur in migraine and each individual set of findings seems to be dependent on which method is used. One method on its own can only disclose a part of all the pathophysiological events. This review is an attempt to consider the capabilities of each method and to bring together the results from different studies on migraine in order to create a complete picture of the cerebrovascular changes which occur during the course of a migraine attack.
