Abstract
Migraine headaches are highly prevalent, affecting 15% of the population. However, despite many studies to determine this disease's mechanism and efficient management, its pathophysiology has not been fully elucidated. There are suggested hypotheses about the possible mediating role of mast cells, immunoglobulin E, histamine, and cytokines in this disease. A higher incidence of this disease in allergic and asthma patients, reported by several studies, indicates the possible role of brain mast cells located around the brain vessels in this disease. The mast cells are more specifically within the dura and can affect the trigeminal nerve and cervical or sphenopalatine ganglion, triggering the secretion of substances that cause migraine. Neuropeptides such as calcitonin gene-related peptide (CGRP), neurokinin-A, neurotensin (NT), pituitary adenylate-cyclase-activating peptide (PACAP), and substance P (SP) trigger mast cells, and in response, they secrete pro-inflammatory and vasodilatory molecules such as interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) as a selective result of corticotropin-releasing hormone (CRH) secretion. This stress hormone contributes to migraine or intensifies it. Blocking these pathways using immunologic agents such as CGRP antibody, anti-CGRP receptor antibody, and interleukin-1 beta (IL-1β)/interleukin 1 receptor type 1 (IL-1R1) axis-related agents may be promising as potential prophylactic migraine treatments. This review is going to summarize the immunological aspects of migraine.

Abstract
Abstract
Background
The prevalence of primary headache in patients with systemic lupus erythematosus (SLE) varies widely and whether it should be attributed to neurological involvement is controversial. We aimed to investigate the prevalence and characteristics of headache in SLE patients, describe its association with disease-related variables and brain imaging, and explore its impact on life.
Results
The overall prevalence of headache was 54.4%, and migraine was the most common type among headache sufferers (48.4%). Headache severity (VAS) and impact (HIT-6) correlated with SLEDAI-2K (P = 0.019 and P < 0.001, respectively) as well as with each other (P = 0.006). Brain imaging abnormalities were found in 25.8%, with white-matter hyperintensities (WMH) being the most frequent pathology. Musculoskeletal manifestations, positive anti-phospholipid (aPL) antibodies, and SLEDAI score ≥ 13.5 were identified as predictors of headache.
Conclusion
Primary headache, especially migraine, is a common feature of patients with SLE, and its presence is associated with negative impact on quality of life. Musculoskeletal features, aPL positivity, and overall disease activity appear to predict primary headache in SLE.

Abstract
The overview is dedicated to the neuroimmunological mechanisms of headache development and chronification. Based on the analyzed data, the authors determined the relationship between immunological parameters and duration, intensity and other characteristics of this disease. These findings confirm that immunocompetent cells can be used as headache biomarkers and predictors of treatment efficacy. Questions about the role of separate parts of the immune system in the development and maintenance of a headache require further research. Studies of humoral immunity appeared to be very promising.

Abstract
OBJECTIVE/BACKGROUND Executive dysfunctions and white matter lesions on magnetic resonance imaging have been reported in migraine. The aim of this study was to determine whether any correlation between these 2 variables exists. MATERIALS AND METHODS Forty-four subjects affected by migraine with or without aura were compared with 16 healthy subjects. A battery of neuropsychological tests assessing executive functions was administered to all subjects. Number and total volume of white matter lesions were assessed in the whole brain and in the frontal lobe. RESULTS The performances of both groups of migraineurs, with and without aura, were significantly worse when compared with controls on Boston Scanning Test. Moreover, we found lower performances compared with controls respectively on Frontal Assessment Battery in patients with migraine with aura and on Controlled Oral Word Association Test in patients with migraine without aura. Nineteen patients (43.2%) and one control subject (6.2%) had white matter lesions. We did not find any significant correlation between white matter lesions load and neuropsychological performances. CONCLUSIONS On the basis of our results, white matter lesions load on magnetic resonance imaging do not seem to contribute to neuropsychological performances deficit in migraineurs.

Risk factors of migraine-related brain white matter hyperintensities: an investigation of 186 patients. J Headache Pain 2011; 12:97-103.

Abstract
Brain white matter hyperintensities are more prevalent in migraine patients than in the general population, but the pathogenesis and the risk factors of these hyperintensities are not fully elucidated. The authors analyzed the routine clinical data of 186 migraine patients who were referred to the Outpatient Headache Department of the Department of Neurology, Medical School, University of Pécs, Hungary between 2007 and 2009: 58 patients with white matter hyperintensities and 128 patients without white matter hyperintensities on 3 T MRI. Significant associations between the presence of white matter hyperintensities and longer disease duration (14.4 vs. 19.9 years, p = 0.004), higher headache frequency (4.1 vs. 5.5 attacks/month, p = 0.017), hyperhomocysteinemia (incidence of hyperintensity is 9/9 = 100%, p = 0.009) and thyroid gland dysfunction (incidence of hyperintensity is 8/14 = 57.1%, p = 0.038) were found. These data support the theory that both the disease duration and the attack frequency have a key role in the formation of migraine-related brain white matter hyperintensities, but the effects of comorbid diseases may also contribute to the development of the hyperintensities.

Abstract
OBJECTIVE To evaluate the association of overall and specific headaches with volume of white matter hyperintensities, brain infarcts, and cognition. DESIGN Population based, cross sectional study. SETTING Epidemiology of Vascular Ageing study, Nantes, France. PARTICIPANTS 780 participants (mean age 69, 58.5% women) with detailed headache assessment. MAIN OUTCOME MEASURES Brain scans were evaluated for volume of white matter hyperintensities (by fully automated imaging processing) and for classification of infarcts (by visual reading with a standardised assessment grid). Cognitive function was assessed by a battery of tests including the mini-mental state examination. RESULTS 163 (20.9%) participants reported a history of severe headache and 116 had migraine, of whom 17 (14.7%) reported aura symptoms. An association was found between any history of severe headache and increasing volume of white matter hyperintensities. The adjusted odds ratio of being in the highest third for total volume of white matter hyperintensities was 2.0 (95% confidence interval 1.3 to 3.1, P for trend 0.002) for participants with any history of severe headache when compared with participants without severe headache being in the lowest third. The association pattern was similar for all headache types. Migraine with aura was the only headache type strongly associated with volume of deep white matter hyperintensities (highest third odds ratio 12.4, 1.6 to 99.4, P for trend 0.005) and with brain infarcts (3.4, 1.2 to 9.3). The location of infarcts was predominantly outside the cerebellum and brain stem. Evidence was lacking for cognitive impairment for any headache type with or without brain lesions. CONCLUSIONS In this population based study, any history of severe headache was associated with an increased volume of white matter hyperintensities. Migraine with aura was the only headache type associated with brain infarcts. Evidence that headache of any type by itself or in combination with brain lesions was associated with cognitive impairment was lacking.

Abstract
OBJECTIVE To investigate the prevalence of mitral valve prolapse (MVP) and abnormalities of haemostasis in children and adolescents with migraine with aura (MA) compared with peers affected by other idiopathic headaches. MATERIALS AND METHODS We recruited 20 MA patients (10 men and 10 women; age range 8-17 years) and 20 sex- and age-matched subjects with other idiopathic headaches. Both groups underwent colour Doppler transthoracic echocardiography to detect MVP and the following laboratory work-up: plasma prothrombin time, activated partial thromboplastin time, thrombin time, fibrinogen, protein C, protein S, homocysteine, lupus anticoagulant, von Willebrand factor (vWF) ristocetin cofactor activity, immunoglobulins (Ig) G and M anticardiolipin antibodies (aCL). Factor V Leiden, factor II and methylenetetrahydrofolate reductase were investigated (we did not test the entire genes, but screened for specific point mutations). RESULTS The prevalence of MVP was significantly higher in the MA subjects than in the patients affected by other idiopathic headaches (40% vs 10%; P < 0.05). Moreover, the MA patients showed a higher rate of above-normal IgM aCL titres (45% vs 10%; P < 0.05). Finally, in the group of patients with MVP we found a higher prevalence of aCL in those with MA compared with those affected by other idiopathic headaches. CONCLUSIONS A proportion, at least, of the MA patients showed a more complex phenotype characterized by MVP and/or positive aCL titres. The pathogenetic role of these associations is obscure and larger studies are needed to confirm the usefulness of echocardiographic and laboratory investigations in this area and to identify possible new treatment approaches that might be explored in this group of MA patients.

Abstract
White matter lesions (WMLs), commonly seen as hyperintensities on T2-weighted MRI scans of healthy elderly individuals, are considered to be related to small vessel disease in the brain, and are often associated with subtle cognitive and functional impairments. WMLs also show a strong correlation with a wide range of neurodegenerative and neuropsychiatric disorders. Although a number of vascular risk factors for WMLs have been identified, genetic factors are also important with twin and family studies reporting high heritability. Mutations in several genes have been described that lead to monogenic disorders manifesting WMLs, such as Fabry disease and CADASIL. Because most individuals with WMLs do not have Mendelian disorders, most of the focus has been on single nucleotide polymorphisms as genetic risk markers for WMLs, either directly or through their interactions with other genes or medical risk factors. Candidate genes examined to date include those involved in cholesterol regulation and atherosclerosis, hypertension, neuronal repair, homocysteine levels, and oxidative stress pathways. In addition, although there have been a few genome-wide linkage studies, only one genome-wide association study has been performed. The majority of the genetic findings need independent replication, and studies need to be extended to other candidate genes. Collaborative efforts to examine genome-wide associations in large samples of both sexes of a broad age range using longitudinal studies are necessary. The identification of individuals genetically at risk of developing white matter lesions will have important implications for recognizing the etiology of WMLs and thereby developing clinical intervention strategies for their prevention.

Abstract
BACKGROUND Large patent foramen ovale (PFO), spontaneous right-to-left shunt, large atrial septal aneurysm (ASA), coagulation abnormalities, and prominent eustachian valve (EV) have all been independently suggested as risk factors for recurrent stroke. We sought to retrospectively evaluate risk of stroke and impact of transcatheter PFO closure in patients with concurrent large PFO, spontaneous right-to-left shunt, large ASA, coagulation abnormalities, and prominent EV. METHODS Between March 2006 and October 2008, 36 (mean age 44 +/- 10.9 years, 28 females) out of 120 consecutive patients referred to our center for transcatheter PFO closure had concomitant diagnosis of (a) large PFO on transcranial Doppler (TCD) and transesophageal echocardiography (TEE), (b) spontaneous right-to-left shunt on TCD, (c) large ASA, (d) prominent EV, and (e) coagulation abnormalities. All patients fulfilled the standard current indications for transcatheter closure and underwent preoperative TEE and brain magnetic resonance imaging (MRI), with subsequent intracardiac echocardiographic-guided transcatheter PFO closure. RESULTS Compared to the remaining PFO population in the same period, patients with all five concomitant features had more ischemic brain lesions on MRI, previous history of recurrent stroke, more frequently a history of venous thromboembolism, and more severe migraine with aura. The concomitance of all the features confers the highest risk of recurrent stroke (OR 9.9, 3.0-18 [95% CI], P < 0.001). CONCLUSIONS Despite its small sample size and nonrandomized retrospective nature, this is the first study to suggest that patients with concurrence of all the investigated characteristics have potentially a higher risk of stroke compared to controls. We thus propose the CARP criteria as a basis for further larger, longitudinal studies to assess the potential benefits of transcatheter closure in this patient subset in the absence of clinical recurrent stroke.

Abstract
Migraine is an independent risk factor for ischemic stroke, mainly in the subpopulation of women with migraine with aura who are younger than 45 years, particularly those that use estrogen containing oral contraceptives. Migraine however should be considered a benign condition as the absolute increase of stroke risk is small. Migraine is also associated with a high prevalence of cerebral white matter hyperintensities, occurring in the deep and periventricular white matter as well as infratentorial, mainly pontine. The pathogenesis and clinical significance of these hyperintensities is unclear. We do not know whether migraine may be considered a progressive disorder in a subset of patients because of accumulation of these hyperintensities over time. Studies on the relationship between migraine and cognitive functioning yielded conflicting results. Two recent studies have provided reassuring news for the migraine patient. A population-based twin study showed that a lifetime migraine diagnosis was not associated with cognitive deficits in middle-aged subjects. A long-term prospective study, assessing cognitive and memory changes in ageing individuals with and without a history of migraine, showed that migraineurs do not exhibit more decline on cognitive tests over time versus controls. Migraine is certainly not a recognized risk factor for (vascular) dementia.

Abstract
CONTEXT The genesis of migraine in patients with patent foramen ovale (PFO) and its relationship with paradoxical stroke is still debated. Some authors agree that migraine with aura and PFO have higher coincidences than would be expected by chance and that it is possible that both conditions are inherited together. OBJECTIVE The present review aims to make a comprehensive attempt at clarifying the PFO-migraine connection in light of recent evidence from literature. EVIDENCE ACQUISITION A Medline search using both OVID and PubMed was performed by searching for literature in English regarding randomized trials, prospective cohort studies, meta-analyses, reviews and editorials about PFO and migraine between 1998 and 2008. Search key words were 'migraine' and 'patent foramen ovale' matched with 'prevalence', 'echocardiography', 'transcranial Doppler ultrasound', 'magnetic resonance imaging', 'coagulation abnormalities' and 'transcatheter closure treatment'. Additional reference material was obtained from the proceedings of relevant conferences on PFO and migraine, and the author's personal experience. EVIDENCE SYNTHESIS Echocardiographic, transcranial Doppler and MRI studies suggest that migraine patients are at higher risk of stroke compared with the normal population and often have white matter brain lesions on MRI. A large proportion of PFO patients have migraine, in particular migraine with aura, and migraine with aura patients plus PFO have larger shunts compared with migraine-free patients. It has been suggested that patients with migraine and large PFO have an increased risk of paradoxical embolism. Most patients with PFO and migraine respond well to transcatheter closure and this fact is unlikely to be caused just by a placebo effect. CONCLUSIONS Although many gray areas are still present, migraine with aura and large PFO seem to be strictly related to both anatomic and functional states at least in a proportion of patients.

Abstract
Migraine headache (with and without aura) is common in the general population and is known to be influenced by genetic factors with heritability estimates between 34-57±. Antiphospholipid syndrome (APS) is a hypercoagulable state characterized by clinical features including venous and arterial thromboses, pregnancy loss and migraine, and by association with antiphospholipid antibodies (aPL). Numerous small studies have investigated whether aPL are associated with migraine in the general population—-with contradictory results. In this study, the question was addressed by studying the prevalence of aPL in members of monozygotic (MZ) twin pairs differing in their migraine status. Such twins provide a unique natural experiment, matched as they are for age, sex and genetic factors, and allow the role of environmental factors, such as aPL, to be determined. Despite 95± power to detect a difference of 0.59 IgG units per litre in anticardiolipin antibody IgG titres, no difference in prevalence of aPL could be detected in migraine-discordant MZ twins.

Abstract
Percutaneous closure of patent foramen ovale (PFO) is still a much debated issue. Although many questions remain open, patients are finding out about PFO management and are beginning to ask for the most rapid and complete solution to their potential problems in spite of the warnings from the medical profession about off-label indications for transcatheter closure. As a result, asymptomatic patients with PFO are coming into medical offices to be assured about stroke risk or treated for any degree of migraine. The cardiologist should be the preferred interlocutor in asymptomatic significant PFO: he is competent in assessing the associated anatomical and functional risk factors, and he is the only specialist who can evaluate on the basis of the anatomo-functional picture the potential risk of paradoxical embolism and discuss with patients eventual off-label indications to closure.
