Abstract
Despite advances in understanding the cause of ischemic stroke, cryptogenic stroke remains a diagnostic and therapeutic challenge for clinicians. Approximately 15% to 40% of all ischemic strokes have no identifiable cause. CS is a diagnosis of exclusion after completing the standard stroke work-up. Further investigation needs to be tailored individually according to results of the clinical evaluation so appropriate secondary prevention strategies can be applied.

Abstract
Several publications have recently suggested that atrial septal defect may be associated with the physiopathology of headache with migraine-type characteristics. We describe four previously asymptomatic paediatric patients with atrial septal defect who underwent percutaneous Amplatzer septal occluder device implantation and who subsequently developed symptoms compatible with migraine headache. The cases had normal echocardiograms after the intervention and a benign course with headache improvement after several weeks or months. There are paediatric patients with atrial septal defect who may dramatically develop migraine symptoms with or without aura following percutaneous correction of their defect. Large paediatric studies are needed to offer accurate prognoses for children and their families. The possibility of using clopidogrel to treat this type of headache is subject to debate.

Abstract
We evaluated 298 patients for right-to-left shunt (RLS) detection by contrast-enhanced transcranial Doppler at rest state (RS), during the conventional Valsalva maneuver (CM), and during the modified Valsalva maneuver (BM: blowing into the connecting tube of a sphygmomanometer at 40 mm Hg for 10 s) in random order, and the degree of RLS along the time of the first microbubble occurrence was recorded. The positive rates were 21.8%, 36.9% and 47.3% for RS, CM and BM, respectively (p < 0.001). BM resulted in a significantly higher positive rate (p = 0.010), and there was a significant difference between the two different methods of VM in terms of the degree of RLS detection (p < 0.001). Further, the first microbubble occurred later during BM than CM (10.22 ± 3.77 s vs. 9.44 ± 4.36 s, p < 0.05). This modified maneuver is an alternative to the conventional one, especially for those who cannot perform the conventional maneuver adequately, but are highly suspected of having RLS.

Abstract
Background and Objectives Patent foramen ovale (PFO) has been implicated in the pathogenesis of cryptogenic stroke or transient ischemic attack (TIA) due to paradoxical embolism, and in the pathogenesis of migraine. This paper reports the intermediate and long-term results of transcatheter closure of PFO associated with cerebrovascular accidents (CVAs), TIAs and migraine, using the Amplatzer PFO occluder. This paper also reports a case of pulmonary embolism which developed in one patient after PFO closure. Subjects and Methods From January 2003 to May 2010, 16 patients with PFO (seven males and nine females) with a history of at least one episode of cryptogenic stroke/TIA, CVA, or migraine and who underwent percutaneous transcatheter closure of PFO using the Amplatzer occluder. All the procedures were performed under general anesthesia and were assisted by transesophageal echocardiography. Results The device was implanted without any significant complications in all the patients, and the PFOs were effectively closed. At an average follow-up period of 54 months, the 15 patients with TIA/CVA had no recurrence of any thromboembolic event. The symptoms in one patient with migraine subsided after occlusion of the PFO. In this study, pulmonary embolism occurred five months after PFO closure in one patient, but the cause of pulmonary embolism was not identified. However, it is believed that the pulmonary embolism occurred without stroke recurrence because occlusion of the PFO was performed when the patient had a stroke event. Conclusion It can be concluded that according to the intermediate and long-term follow-up results, transcatheter PFO closure is an effective and safe therapeutic modality in the prevention of thromboembolic events, especially in the patients with cryptogenic stroke/TIA, and PFO closure is helpful in the treatment of migraine. However, this study involved a small number of patients and also the follow-up period was not long enough. Hence, randomized, controlled trials are necessary to determine if this approach is preferable to medical therapy for the prevention of recurrent stroke or as primary treatment for patients with migraine headache.

Abstract
UNLABELLED Migraine is the most common headache in childhood, and there are some reports that suggest the relationship between migraine and right-to-left shunt. The aim of this study was to evaluate the frequency of right-to-left shunt in children with migraine with aura and compare it with children with migraine without aura, and in healthy children. In a cross-sectional case-control study, we assessed 20 children with migraine with aura, 20 migraine without aura and 20 healthy age, and gender-matched control group. We determined the frequency of right-to-left shunt by transcranial doppler with contrast and transthoracic echocardiography without contrast. The dopplers and echocardiograms were performed blindly by the same examiners during headache-free periods. The presence of right-to-left shunt was found in 13/20 patients with migraine with aura compared with five of 20 migraine without aura and four of 20 control subjects. The frequency of right-to-left shunt in migraine with aura was statistically different from the other two groups (P < 0.005). There was no association between right-to-left shunt and frequency of attacks, duration and intensity of attacks, uni/bilateral occurence, familial occurrence, gender and age of patients. CONCLUSION our findings suggest possible association of migraine with aura and right-to-left shunt. It seems that right-to-left shunt does not influence the clinical features of migraine.

Abstract
We present a new case of cardiac myxoma triggering migraine auras. A 52-year-old woman was suffering from migraine attacks with aura. Magnetic resonance imaging (MRI) showed no abnormalities. Subsequently, she had a minor stroke with multiple ischaemic lesions bilaterally on repeat MRI. An echocardiogram showed a myxoma of the left atrial wall. After removal of the myxoma she was free of symptoms. In the past, seven cardiac myxoma associated migraine patients have been reported. Other cardiac abnormalities, patent foramen ovale in particular, are known to be associated with migraine with aura. We attempted to compare the mechanisms by which cardiac myxoma and other cardiac abnormalities could trigger cortical spreading depression leading to migraine with aura.

Abstract
OBJECTIVE The purpose of this article is to review the latest concepts regarding migraine and ischemic stroke. In addition, focal neurological deficits and MRI changes in migraine patients will be reviewed. METHODS A PubMed search of neurological literature pertaining to this study was conducted using specific keyword search terms pertaining to migraine and ischemic stroke. RESULTS Migraine, especially with aura, is a relative risk factor for stroke. Neuroimaging demonstrates the posterior circulation as being most vulnerable, although the reason for this distribution is unclear. Factors that may contribute to stroke in migraine include changes during cortical spreading depression with hyper- or hypoperfusion of neural tissue, vasospasm and endothelial dysfunction. Estrogen affects migraine expression as well as cerebral circulation, yet most women with migraine without aura are not at increased risk. Co-morbidity with patent foramen ovale can be mechanism of both disorders via presumed lack of filtration of microemboli or toxic substances; however, closure with reversal of right to left shunt seems to be more beneficial for cryptogenic stroke than migraine. Migraine and stroke are found in specific genetic disorders such as CADASIL, HERNS and MELAS giving clues to genetic factors. Stroke associated with migraine treatments such as ergots or triptans is rare, and usually associated with special circumstances such as overuse or concomitant thrombogenic conditions. CONCLUSION Although true migrainous infarction is rare, our understanding of the subtle associations between migraine and cerebrovascular behavior is expanding.

Abstract
Migraine is a common and painful neurological disorder, with genetic and environmental components. Several conditions have been shown to be comorbid with migraine, notably a cardiac malformation affecting the interatrial septum and leading to patent foramen ovale (PFO). Mutations in the development regulatory gene GATA-4, located on human chromosome 8p23.1-p22, have been found to be responsible for some cases of congenital heart defects including PFO. To determine whether the GATA-4 gene is involved in migraine, the present study performed an association analysis of a common GATA-4 variant that results in a change of amino acid (S377G), in a large case/control population (275 unrelated Caucasian migraineurs versus 275 control individuals). The results showed that there was no significant association for this polymorphism between migraine and controls (chi(2) = 0.84, P = 0.66). Thus it appears that the GATA-4 (S377G) mutation does not play a significant role in common migraine susceptibility.

Abstract
AIMS Recently we reported that percutaneous atrial septal defect (ASD) closure had no influence on the prevalence of migraine during a short followup period. 12 % of patients however developed a new-onset migraine after the ASD closure. As it has been suggested that the closing device might induce or maintain migraine temporarily, we were interested in the prevalence of migraine at longer follow-up. METHODS All 75 patients included in the previous study, received the same structured headache questionnaire. A neurologist, blinded to previous data, diagnosed migraine with or without aura (MA+ or MA-) according to the International Headache Criteria. McNemar paired X2 test was used to evaluate changes in the occurrence of migraine. RESULTS Seventy-one patients (94.7%) answer the questionnaire (55 women, mean age at closure 51 +/- 18 years). Mean follow-up time was 52 +/- 13 months. The overall migraine prevalence decreased from 30.7% before to 22.5% after closure (P=0.21). A significant reduction was noted in patients with new-onset migraine early after closure (n=7), where migraine disappeared in 6 patients (P=0.031). In the group with persistent migraine early after closure (n=13), another 6 patients became migraine-free (P=0.031). CONCLUSION Percutaneous ASD closure was not related to a significant decrease in overall migraine prevalence. However, new-onset and persistent migraine early after closure disappeared.

Abstract
Young patients with migraine are at increased risk for stroke, particularly patients with an aura of focal neurologic deficits. Other causes of ischemia are often identified in patients with migraine, including patent foramen ovale, lupus anticoagulant, cervical carotid dissection, arteriovenous malformation, and hyperactivity of the clotting system. Migrainous stroke is only diagnosed when all other possible causes of stroke have been eliminated and the patient has irreversibility of the usual aura, associated with an ischemic infarct in the appropriate brain territory. Prophylactic therapy of migraine with aura may be beneficial in preventing migrainous stroke.

Abstract
Observational evidence from the literature has shown an association between migraine headaches and patent foramen ovale (PFO). This observation has led to hypotheses that could explain the etiology of migraines in those with a PFO, including right-to-left shunting of venous agents such as serotonin that are normally broken down in the pulmonary circulation. Further evidence suggests that closure of a PFO may improve migraine symptoms and serve as an effective treatment modality for migraines. Several randomized controlled double-blinded studies are underway that will more definitively establish the role of specific devices in PFO closure in those suffering from migraines.

Abstract
Findings obtained using animal models have often failed to reflect the processes involved in human disease. Moreover, human cultured cells do not necessarily function as their actual tissue counterparts. Therefore, there is great demand for sources of human progenitor cells that may be directed to acquire specific tissue characteristics and be available in sufficient quantities to carry out functional and pharmacological studies. Acase in point is the mast cell, well known for its involvement in allergic reactions, but also implicated in inflammatory diseases. Mast cells can be activated by allergens, anaphylatoxins, immunoglobulin-free light chains, superantigens, neuropeptides, and cytokines, leading to selective release of mediators. These could be involved in many inflammatory diseases, such as asthma and atopic dermatitis, which worsen by stress, through activation by local release of corticotropin-releasing hormone or related peptides. Umbilical cord blood and cord matrix-derived mast cell progenitors can be separated magnetically and grown in the presence of stem cell factor, interleukin-6, interleukin-4, and other cytokines to yield distinct mast cell populations. The recent use of live cell array, with its ability to study such interactions rapidly at the single-cell level, provides unique new opportunities for fast output screening of mast cell triggers and inhibitors.

Abstract
Treatment of migraine presents special problems in the elderly. Co-morbid diseases may prohibit the use of some medications. Moreover, even when these contraindications do not exist, older patients are more likely than younger ones to develop adverse events. Managing older migraine patients, therefore, necessitates particular caution, including taking into account possible pharmacological interactions associated with the greater use of drugs for concomitant diseases in the elderly. Paracetamol (acetaminophen) is the safest drug for symptomatic treatment of migraine in the elderly. Use of selective serotonin 5-HT(1B/1D) receptor agonists ('triptans') is not recommended, even in the absence of cardiovascular or cerebrovascular risk, and NSAID use should be limited because of potential gastrointestinal adverse effects. Prophylactic treatments include antidepressants, beta-adrenoceptor antagonists, calcium channel antagonists and antiepileptics. Selection of a drug from one of these classes should be dictated by the patient's co-morbidities. Beta-adrenoceptor antagonists are appropriate in patients with hypertension but are contraindicated in those with chronic obstructive pulmonary disease, diabetes mellitus, heart failure and peripheral vascular disease. Use of antidepressants in low doses is, in general, well tolerated by elderly people and as effective, overall, as in young adults. This approach is preferred in patients with concomitant mood disorders. However, prostatism, glaucoma and heart disease make the use of tricyclic antidepressants more difficult. Fewer efficacy data in the elderly are available for selective serotonin reuptake inhibitors, which can be tried in particular cases because of their good tolerability profile. Calcium channel antagonists are contraindicated in patients with hypotension, heart failure, atrioventricular block, Parkinson's disease or depression (flunarizine), and in those taking beta-adrenoceptor antagonists and monoamine oxidase inhibitors (verapamil). Antiepileptic drug use should be limited to migraine with high frequency of attacks and refractoriness to other treatments. Promising additional strategies include ACE inhibitors and angiotensin II type 1 receptor antagonists because of their effectiveness and good tolerability in patients with migraine, particularly in those with hypertension. Because of its favourable compliance and safety profile, botulinum toxin type A can be considered an alternative treatment in elderly migraine patients who have not responded to other currently available migraine prophylactic agents. Pharmacological treatment of migraine poses special problems in regard to both symptomatic and prophylactic treatment. Contraindications to triptan use, adverse effects of NSAIDs, and unwanted reactions to some antiemetics reduce the list of drugs available for the treatment of migraine attacks in elderly patients. The choice of prophylactic treatment (beta-adrenoceptor antagonists, calcium channel antagonists, antiepileptics, and more recently, some antihypertensive drugs) is influenced by co-morbidities and should be directed at those drugs that are believed to have fewer adverse effects and a better safety profile. Unfortunately, for most of these drugs, efficacy studies are lacking in the elderly.

Abstract
When a patient with migraine has a stroke, all other causes of stroke should be ruled out before the stroke is attributed to migraine. Migraine mimics that present with headaches and stroke, including arteriovenous malformation and cervical carotid artery dissection, should be considered. Patent foramen ovale is a risk factor for both migraine and stroke and should be ruled out with transesophageal echocardiography. A patient with migraine with aura with persistent focal neurologic deficits in the distribution of the typical aura can be diagnosed with migrainous stroke. Patients with migraine with aura with persistent focal neurologic deficits can be treated pharmacologically with intravenous verapamil or magnesium sulfate to relieve the symptoms in familial hemiplegic migraine and sporadic hemiplegic migraine. Prophylactic treatment should be administered to patients with frequent attacks of migraine with aura to prevent recurrence. Oral verapamil is recommended for patients with familial hemiplegic migraine and may be effective in patients with sporadic hemiplegic migraine. Endovascular closure of patent foramen ovale has been reported to prevent recurrence of migraine with aura. The role of patent foramen ovale closure remains controversial pending completion of controlled randomized trials.

Abstract
The aim of this study was to investigate the prevalence of patent foramen ovale (PFO) in a consecutive unselected cohort of migraine patients (with and without aura) and compare it with a group of ischaemic young and elderly stroke patients. One hundred and forty-one migraine patients were compared with 330 stroke patients (130 young patients; 200 elderly patients) selected from our hospital stroke data bank. PFO was assessed with transcranial Doppler sonography with i.v. injection of agitated saline. The prevalence of PFO was 51.7% in migraine with aura (MA) patients, 33.7% in migraine without aura (MoA) patients, 33.8% in young stroke patients and 20.5% in elderly stroke patients (P < 0.001). The prevalence of PFO in cryptogenic stroke in young and elderly stroke patients was, respectively, 41.1% and 25% (P = 0.04). The difference between MA and MoA patients was significant (odds ratio = 2.1). The prevalence of PFO in MA patients is higher than in MoA patients and in young cryptogenic stroke patients.

Abstract
Approximately 30% of patients suffer a recurrent stroke during the 5 years after their first cerebrovascular event. Predictors differ for short- and long-term risk of stroke recurrence. Atherosclerotic disease is the single most important predictor for short-term recurrence, while most classical cardiovascular risk factors, as well as age, are independent predictors for long-term recurrence. Several prognostic models for long-term risk of recurrent stroke have been validated, but the predictive value and applicability of these models remains limited. However, an improved understanding of the risk for recurrent stroke is vital for the design of secondary prevention trials as well as individual treatment decisions, especially if the medication or procedure is expensive or risky. The aim of this article is to elucidate the relationship between stroke risk factors, prognostic scores and their predictive value in recurrent stroke.

Abstract
Patients with migraine are at increased risk for white matter hyperintensities detected on magnetic resonance imaging. The presence of nonspecific white matter hyperintensities may cause uncertainty for physicians and anxiety for patients. The pathophysiology and long-term consequences of these lesions are unknown. Occasionally, white matter lesions in a migraineur may indicate an underlying disease such as cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), mitochondrial encephalopathy with lactic acidosis and stroke-like episodes (MELAS), or central nervous system vasculitis. The ability to distinguish between nonspecific and disease-specific patterns of white matter hyperintensities in migraine sufferers is important for the practicing clinician.
