Abstract
INTRODUCTION It has been observed in recent years that levels of such molecules as calcitonin gene-related peptide (CGRP) and, to a lesser extent, the pituitary adenylate cyclase-activating peptide are elevated during migraine attacks and in chronic migraine, both in the cerebrospinal fluid and in the serum. Pharmacological reduction of these proteins is clinically significant, with an improvement in patients' migraines. It therefore seems logical that one of the main lines of migraine research should be based on the role of CGRP in the pathophysiology of this entity. DEVELOPMENT The Spanish Society of Neurology's Headache Study Group decided to draft this document in order to address the evidence on such important issues as the role of CGRP in the pathophysiology of migraine and the mechanism of action of monoclonal antibodies and gepants; and to critically analyse the results of different studies and the profile of patients eligible for treatment with monoclonal antibodies, and the impact in terms of pharmacoeconomics. CONCLUSIONS The clinical development of gepants, which are CGRP antagonists, for the acute treatment of migraine attacks, and CGRP ligand and receptor monoclonal antibodies offer promising results for these patients.

Abstract
INTRODUCTION After the European Headache Federation (EHF) Congress, renowned Spanish neurologists specialised in migraine presented the most significant latest developments in research in this field at the Post-EHF Meeting. DEVELOPMENT The main data presented concerning the treatment of chronic and episodic migraine were addressed, with attention paid more specifically to those related to preventive treatments and real-life experience in the management of the disease. An important review was carried out of the new therapeutic targets and the possibilities they offer in terms of understanding the pathophysiology of migraine and its treatment. An update was also presented of the latest developments in the treatment of migraine with fremanezumab, a monoclonal antibody recently authorised by the European Medicines Agency. Participants were also given an update on the latest developments in basic research on the pathology, as well as an overview of the symptoms of migraine and COVID-19. Finally, the repercussions of migraine in terms of its burden on the care and economic resources of the health system were addressed, along with its impact on society. CONCLUSIONS The meeting summarised the content presented at the 14th EHF Congress, which took place in late June/early July 2020.

Abstract
BACKGROUND AND PURPOSE OnabotulinumtoxinA is a treatment specifically approved for the prophylaxis of chronic migraine in adults. The aim of this study was to assess the effectiveness of OnabotulinumtoxinA in chronic migraine after 1 year of treatment in a real-life setting and to identify clinical predictors of outcome. METHODS We designed a prospective multicentre study performed in 13 hospitals in Spain. Patients underwent a complete medical history and examination. They were treated with OnabotulinumtoxinA every 12 weeks for 1 year. Data about outcome, adverse events, abortive medication use, emergency room use and disability were collected at 3 and 12 months. RESULTS A total of 725 subjects completed the study. At 12 months, 79.3% showed >50% reduction in number of headaches per month and 94.9% reported no adverse events. Unilaterality of pain, fewer days of disability per month and milder headache at baseline were correlated with good outcome. Duration of disease <12 months increased the chances of response to treatment with OnabotulinumtoxinA (odds ratio, 1.470; 95% confidence interval, 1.123-2.174; P = 0.045). CONCLUSIONS This study confirmed the effectiveness of treatment with OnabotulinumtoxinA after 1 year of treatment. The chances of a good outcome may be increased by starting treatment in the first 12 months after chronic migraine diagnosis.

Abstract
The aim was to explore whether combining a β-blocker and sodium valproate could lead to an advantage in efficacy in patients with migraine previously resistant to the two medications in monotherapy. Fifty-two patients (43 women) with a history of episodic migraine with or without aura, and previously unresponsive to β-blockers and sodium valproate in monotherapy, were treated with a combination of propranolol or nadolol and sodium valproate in an open-label fashion. Eight patients (15%) discontinued due to adverse events. Fifteen (29%) did not respond. The remaining 29 cases (56%) showed response (>50% reduction in migraine days). The response was excellent in nine (17%). From this open trial, combination therapy with a β-blocker and sodium valproate appears to be a good migraine preventative in some previously resistant migraine cases. Controlled trials are now necessary to determine the true advantage in efficacy of this combination in difficult to treat migraineurs.

Abstract
BACKGROUND AND PURPOSE Chronic periodontitis (ChP) and lacunar infarct (LI) are two common diseases amongst the elderly. Although several studies have shown an association between ischaemic stroke and ChP, little is known about the relationship between ChP and LI. The study aims to investigate whether ChP is associated with the presence of lacunar stroke. METHODS An age- and gender-matched case-control study of 62 cases (subjects diagnosed with LI) and 60 controls is reported. Clinical periodontal measures (probing pocket depth, recession, clinical attachment level, full mouth plaque score and full mouth gingival bleeding on probing score) were assessed, and associated risk factors for periodontitis and lacunar stroke were ascertained by means of a structured questionnaire. RESULTS Chronic periodontitis showed a strong association with LI after adjusting for common vascular risk factors (odds ratio 4.20; 95% confidence interval 1.81-10.20; P = 0.001). Likewise, severe ChP and LI also tended to be significantly associated, independent of other vascular covariates (odds ratio 3.53; 95% confidence interval 1.07-12.77; P = 0.04). CONCLUSIONS Chronic periodontitis was independently associated with the presence of LI after adjusting for well-known vascular risk factors for lacunar stroke. Further observational studies are necessary to investigate the pathophysiological mechanisms that can explain this relationship.

Abstract
Headache is the most common reason for visiting in neurology. Almost a third of all patients surveyed in this specialty visit for this reason. The gradual increase in the complexity of the care afforded to patients with headaches requires neurologists to become more specialised and leads to the creation of specialised units where this more complex care can be implemented. The heads of the neurology department are responsible for structuring and coordinating the different care units. This article shows the findings of a survey carried out on a group of heads of neurology departments in order to determine the current state of headache units, that is, their opinion regarding the creation, functioning and development of headache units in Spanish hospitals, and the parameters of their efficacy and effectiveness.

Abstract
INTRODUCTION AND AIMS This study was aimed determining the effectiveness, tolerance and satisfaction of patients with migraine as regards different triptans, according to the characteristics of their attacks. At the same time it sought to establish a predictive model that can be used to recommend one or another, depending on those characteristics. PATIENTS AND METHODS Retrospective observation-based study conducted in headache units in a number of different centres. Patients included in the study were those with migraine who used the same triptan to treat their attacks. Data concerning preference, effectiveness, speed and tolerance were analysed. RESULTS The analysis included 160 patients (88 females), with a mean age of 42.92 years. The most commonly used triptans were eletriptan, almotriptan and rizatriptan. Both patients and doctors reported a high degree of satisfaction (88% and 65%) with the triptan that was used. In the surveys on preference, patients preferred their current triptan to the previous one (83%) or to non-specific drugs. The overall score on a visual analogue scale was above 7 for all the triptans, without any differences from one to another. On analysing the use of a particular triptan depending on the characteristics of the attacks, no statistically significant differences were found. CONCLUSIONS In this selected group of patients, triptans are a treatment that patients claim to be very satisfied with. Although there are no overall differences in the scores among different triptans, the fact that certain triptans are used more by patients after previous experiences with others suggests that they are more effective. We did not find any parameter that predicts the use of a particular triptan.

Abstract
SUMMARY BACKGROUND Growth factors (GF) such as vascular endothelial growth factor (VEGF), angiopoietin-1 (Ang-1) and granulocyte-colony stimulating factor (G-CSF) have been associated with greater efficacy of tissue plasminogen activator (tPA) in experimental studies. OBJECTIVES To study the association of these GF with arterial recanalization and clinical outcome in patients with acute ischemic stroke treated with tPA. METHODS We prospectively studied 79 patients with ischemic stroke attributable to MCA occlusion treated with i.v. tPA within the first 3 h from onset of symptoms. Continuous transcranial color-coded sonography (TCCS) was performed during the first 2 h after tPA bolus to assess early MCA recanalization. Hemorrhagic transformation (HT) was classified according to ECASS II definitions. Good functional outcome was defined as a Rankin scale score of 0-2 at 90 days. GF levels were determined by ELISA. RESULTS Mean serum levels of VEGF, G-CSF and Ang-1 at baseline were significantly higher in patients with early MCA recanalization (n = 30) (all P < 0.0001). In the multivariate analysis, serum levels of VEGF (OR, 1.03), G-CSF (OR, 1.02) and Ang-1 (OR, 1.07) were independently associated with early MCA recanalization (all P < 0.0001). On the other hand, patients with parenchymal hematoma (PH) (n = 20) showed higher levels of Ang-1 (P < 0.0001). Ang-1 (OR, 1.12; P < 0.0001) was independently associated with PH, whereas patients with good outcome (n = 38) had higher levels of G-CSF (P < 0.0001). G-CSF was independently associated with good outcome (OR, 1.12; P = 0.036). CONCLUSIONS These findings suggest that GF may enhance arterial recanalization in patients with ischemic stroke treated with t-PA, although they might increase the HT.

Abstract
In order to evaluate the contribution of 19 serotonin-related genes to the susceptibility to migraine in a Spanish population we performed a case-control association study of 122 single nucleotide polymorphisms (SNPs), selected according to genetic coverage parameters, in 528 migraine patients -308 with migraine without aura (MO) and 220 with migraine with aura (MA)- and 528 sex-matched migraine-free controls. The single-marker analysis identified nominal associations with the migraine phenotype or with the MO or MA subtypes. The multiple-marker analysis revealed risk haplotypes in three genes that remained significantly associated with migraine after correction by permutations. Two-marker risk haplotypes were identified in the HTR2B (rs16827801T-rs10194776G) and MAOA (rs3027400G-rs2072743C) genes conferring susceptibility to MO, and a four-marker haplotype in DDC was specific of MA (rs2329340A-rs11974297C-rs2044859T-rs11761683G). The present study supports the involvement of HTR2B and MAOA genes in the genetic predisposition to MO, while DDC might confer susceptibility to MA. These results suggest a differential involvement of serotonin-related genes in the genetic background of MO and MA.

Abstract
BACKGROUND Depression is a frequent mood disorder that affects around 33% of stroke patients and has been associated with both poorer outcome and increased mortality. Our aim was to test the possible association between inflammatory and neurotrophic molecular markers and the development of post-stroke depression. METHOD We studied 134 patients with a first episode of ischemic stroke without previous history of depression or speech disorders. We screened for the existence of major depression symptoms in accordance with DSM-IV criteria and a Yesavage Geriatric Depression Scale (GDS) score >11 at discharge and 1 month after stroke. At these times, serum levels of molecular markers of inflammation [interleukin (IL)-1beta, IL-6, intracellular adhesion molecule 1 (ICAM-1), tumor necrosis factor (TNF)-alpha, leptin and high-sensitivity C-reactive protein (hs-CRP)] and neurotrophic factors [brain-derived neurotrophic factor (BDNF)] were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS Twenty-five patients (18.7%) were diagnosed as having major depression at discharge. Out of 104 patients who completed the follow-up period, 23 were depressed at 1 month (22.1%). Patients with major depression showed higher serum leptin levels at discharge [43.4 (23.4-60.2) v. 6.4 (3.7-16.8) ng/ml, p<0.001] and at 1 month after stroke [46.2 (34.0-117.7) v. 6.4 (3.4-12.2) ng/ml, p<0.001). Serum levels of leptin >20.7 ng/ml were independently associated with post-stroke depression [odds ratio (OR) 16.4, 95% confidence interval (CI) 5.2-51.5, p<0.0001]. Leptin levels were even higher in the eight patients who developed depression after discharge [114.6 (87.6-120.2) v. 7.2 (3.6-13.6) ng/ml, p<0.0001]. CONCLUSIONS Serum leptin levels at discharge are found to be associated with post-stroke depression and may predict its development during the next month.

Abstract
INTRODUCTION AND DEVELOPMENT Leukoaraiosis is a radiological term which refers to white matter disturbances observed as a hypodensity in computed tomography and hyperintensity in T2-weighted magnetic resonance image. The most accepted theory to explain the mechanism of production of leukoaraiosis is chronic ischemia, due to a damage in penetrating arteries. It is an entity with increasing interest, since it is associated with the presence of cognitive impairment. Clinical manifestations in relation with cognitive functions range from mild affectation to dementia, affecting the processing speed and executive functions. CONCLUSIONS It seems that the control of vascular risk factors slow the progression of leukoaraiosis and cognitive impairment, and although there are no really effective treatment, it seems that some drugs, such as acetylcholinesterase inhibitors or NMDA-receptor antagonists, exert a beneficial effect, although slight, in cognitive functions.

Abstract
INTRODUCTION About half of the patients with chronic migraine do not respond or do not tolerate the different migraine preventatives. AIM To analyse the efficacy and tolerability of zonisamide in the treatment of migraine in patients who had not responded or tolerated topiramate, the current drug of choice for the treatment of this condition. PATIENTS AND METHODS Those patients with no response or intolerance to topiramate received zonisamide. This drug was increased 25 mg per week up to a maximum of 200 mg/day. The efficacy of this drug was evaluated in terms of 'response' (reduction in attack frequency below 50%) at the third month of treatment. RESULTS Our series comprises a total of 34 patients, most of them middle-aged women. All met chronic migraine criteria. Zonisamide showed efficacy (response) in 19 patients (56%), response being excellent in 6 (18%). Nine patients (26%) did not show response, whereas 6 (18%) did not tolerate the drug. CONCLUSIONS The results, obtained in patients refractory to other preventatives and particularly to topiramate, suggest that zonisamide can be useful in the prevention of chronic migraine. Of course, controlled clinical trials are necessary to confirm these preliminary results.

Abstract
INTRODUCTION During brain ischemia, neurotoxicity, neuroinflammation and blood-brain barrier (BBB) disruption mechanisms are involved, leading to necrosis, edema and hemorrhagic transformation. Cranial computed tomography (CT) is the most widely used method in the diagnosis of acute stroke, and its early performance may help in the selection of patients for certain treatments. Our objective is to identify molecular markers of neuroexcitotoxicity, neuroinflammation and BBB disruption in the acute phase of stroke that might be associated with early ischemic CT signs. METHODS 311 patients with ischemic stroke within the first 24 h from symptoms onset were prospectively included. We established tres groups based on the time between symptom onset and hospital arrival: < or = 6 h, between 6 and 12 h and >12 h. Cranial CT was performed at admission to evaluate early ischemic signs according to the Alberta Stroke Program Early CT Score (ASPECTS). Blood samples were taken at admission for the determination of molecular markers of neuroexcitotoxicity (glutamate), neuroinflammation (interleukin [IL]-6) and BBB disruption (metalloproteinase [MMP]-9). RESULTS Patients with ASPECTS score < or =7 showed a worse early and late prognosis. Glutamate >134.4 microM (OR: 9.7; CI 95%: 4.2-22.5; p<0.001), IL-6>15.5 pg/mL (OR: 4.4; CI 95%: 2.1-9.4; p<0.001) and MMP-9 > 87.2 ng/mL (OR: 18.4; CI 95%: 7.2-47.1; p<0.001) were associated with ASPECTS score < or =7. In the logistic regression model, only glutamate >134.4 microM/l in the first 6 h (OR: 13.2; CI95%: 5.4-31.3; p<0.001), IL-6>15.5 pg/mL from 6 to 12 h (OR: 10.5; CI 95 %: 4.1-26.7; p<0.001) and MMP-9 >87.2 ng/ml after 12 h (OR: 24.2; CI 95%: 4.8- 50.2; p < 0.001) were independently associated with ASPECTS score < or = 7. CONCLUSIONS The ASPECTS score may be considered as a surrogate marker of early neurological deterioration and final infarct volume, and associated with molecular markers of neuroexcitotoxicity, neuroinflammation and BBB disruption.

Abstract
BACKGROUND Pretreatment with statins has been shown to reduce brain injury in cerebral ischemia. In this controlled randomized study, we investigated the influence of statin pretreatment and its withdrawal on the outcome of acute ischemic stroke patients. METHODS From 215 patients admitted within 24 hours of a hemispheric ischemic stroke, 89 patients on chronic statin treatment were randomly assigned either to statin withdrawal for the first 3 days after admission (n = 46) or to immediately receive atorvastatin 20 mg/day (n = 43). The primary outcome event was death or dependency (modified Rankin Scale [mRS] score > 2) at 3 months. Early neurologic deterioration (END) and infarct volume at days 4 to 7 were secondary outcome variables. In a secondary analysis, outcome variables were compared with the nonrandomized patients without previous statin therapy (n = 126). RESULTS Patients with statin withdrawal showed a higher frequency of mRS score > 2 at the end of follow-up (60.0% vs 39.0%; p = 0.043), END (65.2% vs 20.9%; p < 0.0001), and greater infarct volume (74 [45, 126] vs 26 [12, 70] mL; p = 0.002) compared with the non-statin-withdrawal group. Statin withdrawal was associated with a 4.66 (1.46 to 14.91)-fold increase in the risk of death or dependency, a 8.67 (3.05 to 24.63)-fold increase in the risk of END, and an increase in mean infarct volume of 37.63 mL (SE 10.01; p < 0.001) after adjusting for age and baseline stroke severity. Compared with patients without previous treatment with statins, statin withdrawal was associated with a 19.01 (1.96 to 184.09)-fold increase in the risk of END and an increase in mean infarct volume of 43.51 mL (SE 21.91; p = 0.048). CONCLUSION Statin withdrawal is associated with increased risk of death or dependency at 90 days. Hence, this treatment should be continued in the acute phase of ischemic stroke.

Abstract
Migraine is the most frequent neurological reason for consultation. The differences regarding health care system, type of professional seeing these patients and therapeutic armamentarium available in the different countries are important, which makes it very recommendable to have an action guide that reflects the local clinical practice. Following the year 2005 WHO recommendations in its "Global Campaign" against migraine, the coordinators of the Headache Study Groups of the Spanish Society of Neurology, the Spanish Society of Family and Community Medicine, the Spanish Society of Rural and General Medicine, the Spanish Society of General Medicine and the Global Campaign decided to jointly make this guide. To do so, they made a search in MEDLINE, using the terms "migraine", "migraine treatment" and "headache guidelines" and "migraine guidelines". The most relevant articles were analyzed, including the references that we considered to be of interest. Furthermore, we reviewed the most important textbooks on headache and migraine. In this paper, we detail the recommendations agreed on, according to the evidence grade, on symptomatic and preventive treatment of migraine.

Abstract
OBJECTIVE To test treatment combining a beta-blocker plus topiramate in migraine patients previously resistant to the two medications in monotherapy. PATIENTS AND METHODS Those patients who had not responded to a beta-blocker and topiramate received combined treatment. RESULTS Fifty-eight patients (47 women, age 25-76 years) received the combined treatment. Thirty-three (57%) met criteria for chronic migraine/medication overuse headache, 18 (31%) for migraine without aura and seven (12%) with aura. Ten (17%) discontinued due to adverse events. Among the 48 patients who tolerated the combination, 36 (75%, 62% of the total series) showed response (>50% reduction in frequency), while 12 (25%) did not. The number of days with headache/month decreased from 15.1 to 6.5 (-57%). Sixteen (44% of responders) showed an excellent (>75%) response. Eighteen patients (38%) experienced a total of 26 adverse events (mild-moderate). CONCLUSIONS The combination of beta-blocker plus topiramate showed a benefit in around 60% of patients who had not previously responded to monotherapy. Adverse events led to discontinuation in one out of six patients. From these open results, it seems reasonable to recommend this combination, complementary in terms of mechanism of action, as a potential strategy in patients with refractory migraine.

Abstract
OBJECTIVE To study the association of previously unknown high blood pressure (HBP) during the acute phase of stroke (new-onset hypertension) with the inflammatory response and clinical outcome. METHODS We classified 844 patients with hemispheric ischemic stroke into three groups according to history of hypertension and presence of HBP within the first 24 hours after symptom onset: Group I (n = 412), normotensive patients; Group II (n = 265), chronic hypertensive patients; and Group III (n = 167), new-onset hypertensive patients. Interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-alpha), intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), and metalloproteinase 9 (MMP-9) were measured in blood samples obtained on admission. The influence of new-onset HBP and markers of inflammation on poor neurologic outcome at 3 months was evaluated by logistic regression analysis. RESULTS New-onset HBP was found in 19.9% of patients. Patients in this group had higher plasma concentrations of IL-6, TNF-alpha, ICAM-1, VCAM-1, and MMP-9 than the other two groups. New-onset HBP was associated with poor outcome at 3 months (odds ratio [OR] 2.10; 95% CI 1.54 to 3.52; p < 0.0001) after adjustment for other prognostic factors. However, when markers of inflammation were included in the model, IL-6 (OR 1.01; 95% CI 1.00 to 1.03; p = 0.020) and MMP-9 (OR 1.01; 95% CI 1.00 to 1.01; p < 0.0001), but not new-onset HBP, were independently associated with poor neurologic outcome. CONCLUSIONS New-onset high blood pressure in acute ischemic stroke, but not chronic hypertension, is associated with an inflammatory response and poor neurologic outcome.

Abstract
BACKGROUND Hemorrhagic transformation (HT) after cerebral ischemia seems to be related to the endothelial disruption secondary to the ischemic process. Albuminuria has recently been found to be a marker of chronic endothelial damage. OBJECTIVE To investigate the relationship between albuminuria and HT in patients with acute ischemic stroke. METHODS We studied 200 patients (51.5% men, age 72.5 +/- 8.5 years) with ischemic stroke within the first 24 hours of evolution. HT development was assessed on CT performed between days 4 and 7 of evolution and classified according to the ECASS II criteria. Urinary samples were collected within the first 3 hours after admission and the presence of albuminuria, which was considered to be present when the ratio albumin-to-creatinine was > or =30 mg/g creatinine, was determined by nephelometry within the first 24 hours of evolution. RESULTS Forty-nine patients (24.5%) had albuminuria and 36 (18%) had HT on the second CT scan. After adjusting for potential confounders including a previous history of diabetes mellitus, hypertension and atrial fibrillation, stroke severity, the presence of early signs of ischemia and leukoaraiosis on the baseline CT scan, and IV anticoagulant treatment, logistic regression analysis showed that albuminuria was independently associated with HT (OR, 7.45; 95% CI 2.30 to 24.16). Moreover, albuminuria was also a significant and independent predictor of parenchymal hemorrhage type 1 and 2 (OR, 8.30; 95% CI 1.77 to 38.89). CONCLUSION Albuminuria is an independent predictor of hemorrhagic transformation, and particularly of the most severe bleedings, in patients with acute ischemic stroke. Due to the small number of events, the predictive capacity of albuminuria should be confirmed in larger studies.

Abstract
UNLABELLED The influence of temperature on the outcome observed in experimental models of ischaemic stroke has not been definitively proved in patients with stroke. Interleukin-6 (IL-6) acts as important endogenous pyrogen, and it is an important regulator of spontaneous body temperature during cerebral ischaemia. The objective of this study was to determine, during the acute phase of cerebral ischaemia, the potential relationship between proinflammatory cytokines and hyperthermia as a cause of larger cerebral infarcts. PATIENTS AND METHODS We studied 229 patients with a first-ever acute hemispheric infarction admitted within the first 24 h from onset of symptoms. On admission, axillary temperature was recorded and blood chemistry studies and cranial computed tomography were performed. We classified body temperature into two groups: hyperthermia (>or=37.5 degrees C) and normothermia (<37.5 degrees C). We determined proinflammatory markers [IL-6, tumour necrosis factor-alpha (TNF-alpha), intercellular adhesion molecule (ICAM-1) and vascular cellular adhesion molecule] on admission. Two outcome variables were evaluated: (i) infarct volume; (ii) Canadian Stroke Scale (CSS) at 3 months (CSS <or= 7 was considered poor outcome and CSS > 7 good outcome). RESULTS Patients with hyperthermia had higher infarct volume [46.5 (9.8-78.5) cm(3) vs. 19.1 (5.0-23.5) cm(3); P < 0.0001], as well as poor outcome at 3 months. Plasma levels of IL-6, TNF-alpha and ICAM-1 were significantly higher in the group of patients with hyperthermia than in the normothermic group. There was a significant correlation between body temperature on admission and infarct volume (r = 0.302; P < 0.0001), and between proinflammatory markers (IL-6 and TNF-alpha) and infarct volume. A significant association was also found between proinflammatory markers (IL-6, TNF-alpha, and ICAM-1) and poor outcome. However, after adjustment for potential confounders, hyperthermia was not independently associated with either larger infarct volume or with poor outcome at 3 months. CONCLUSIONS Inflammatory mediators play a role in acute ischaemic brain damage independently of hyperthermia.

Abstract
OBJECTIVE To determine potential predictors of good outcome in primary medium to large intracerebral haemorrhages (ICH) which could be useful for selecting patients for surgical procedures. METHODS Subjects were 138 patients with spontaneous hemispheric ICH >20 ml. They were non-surgically treated and were admitted consecutively to 15 hospitals within the first 12 hours of symptom onset (mean (SD), 5.8 (3.1) hours). Haematoma volume was measured on computed tomography (CT) at admission. Stroke severity was assessed by the Canadian stroke scale (CSS). Good outcome was defined as modified Rankin score < or =2 at three months. RESULTS At the end of the follow up period, 45 patients (32.6%) had good outcome. Baseline stroke severity, systolic and diastolic blood pressure, body temperature, and acute phase reaction biochemical markers (ESR, C-reactive protein, fibrinogen, neutrophil count) were significantly associated with good outcome in bivariate analyses. Of the initial CT scan variables, intraventricular contamination, deep location, mass effect, and greater ICH volume were related to poor outcome. On multiple logistic regression analysis, cortical location of bleeding (odds ratio 3.79 (95% confidence interval 1.2 to 12.01); p = 0.023), high CSS score (OR 2.3 (1.6 to 3.1); p<0.0001), and low fibrinogen concentrations (OR 0.92 (0.87 to 0.97); p = 0.001) were independent predictors of good outcome. These three factors correctly classified 85% of patients. CONCLUSIONS Good outcome in medium to large ICH can be predicted on admission by three readily assessable factors (CSS score, ICH location, and fibrinogen levels). These predictors may be helpful in selecting patients for surgical treatment.

Abstract
OBJECTIVE To evaluate the usefulness of a mismatch between the severity of acute clinical manifestations and the diffusion-weighted imaging (DWI) lesion in predicting early stroke outcome and infarct volume. METHODS One hundred sixty-six patients with a hemispheric ischemic stroke of <12 hours' duration were studied. The NIH Stroke Scale (NIHSS) score and the volume of DWI lesion were measured on admission and at 72 +/- 12 hours. Infarct volume was measured on T2-weighted or fluid-attenuated inversion recovery images at day 30. Early neurologic deterioration (END) was defined as an increase of > or =4 points between the two NIHSS evaluations. Thirty-eight patients received IV thrombolysis or abciximab. Clinical-DWI mismatch (CDM) was defined as NIHSS score of > or =8 and ischemic volume on DWI of < or =25 mL on admission. The adjusted influence of CDM on END, DWI lesion enlargement at 72 hours, and infarct growth at day 30 was evaluated by logistic regression analysis and generalized linear models. RESULTS CDM was found in 87 patients (52.4%). Patients with CDM had a higher risk of END than patients without CDM because NIHSS < 8 (odds ratio [OR], 9.0; 95% CI,1.9 to 42) or DWI lesion > 25 mL (OR, 2.0; 95% CI, 0.8 to 4.9). CDM was associated with an increase of 46 to 68 mL in the mean volume of DWI lesion enlargement and infarct growth in comparison with non-CDM. All the effects were even greater and significant in patients not treated with reperfusion therapies. CONCLUSIONS Acute stroke patients with an NIHSS score of > or =8 and DWI volume of < or =25 mL have a higher probability of infarct growth and early neurologic deterioration. The new concept of CDM may identify patients with tissue at risk of infarction for thrombolytic or neuroprotective drugs.

Abstract
INTRODUCTION Eletriptan is a recently marketed second-generation triptan with a potent agonist activity on 5-HT1B/ 1D receptors. Our aim has been to analyze the specific results from the Spanish participation in phase IIIa and IIIb clinical trials vs placebo and compare them with the results obtained in the global clinical development of eletriptan. PATIENTS AND METHODS Analysis of the results obtained in 40 centers in Spain (358 patients) vs global sample 4,677 patients) for the first migraine attack in 6 controlled clinical trials with eletriptan 40 mg, eletriptan 80 mg and placebo. This ad hoc analysis was carried out for those treatment groups with more than 50 patients, which reduced the final number of patients from Spain to 250. RESULTS The proportion of patients with relief at 2 hours (main endpoint) in the Spanish sample was 22 %, 59 % and 67 % for placebo, eletriptan 40 mg and eletriptan 80 mg, respectively. These values were significantly higher (p < 0.05) than those of placebo and similar to those from the total sample. The proportion of pain free patients at 2 hours in the Spanish sample was 10 %, 36 % and 41 % for placebo, eletriptan 40 mg and eletriptan 80 mg, respectively. These values were significantly better than those for placebo (p < 0.05) and about 15 %-20 % higher than those from the total sample. Recurrence rate in the Spanish sample was 50 %, 16 % and 25 % for placebo, eletriptan 40 and eletriptan 80 mg, respectively, and did not differ from that of the total sample. Sustained relief for the two eletriptan doses was 46 % for both eletriptan 40 and eletriptan 80, this being significant (p < 0.05) over placebo (11 %) for the Spanish sample and similar to that of the global sample. The results for other efficacy parameters, such as need of rescue medication, functional response at 2 hours, complete response for pain-freeness and acceptability followed a similar pattern. Eletriptan was, in general, well-tolerated. Adverse events were slight-moderate in intensity, transient and were not different, either in profile or proportion, from those from the global sample. CONCLUSIONS These results confirm eletriptan 40 mg and 80 mg as an excellent option for the symptomatic treatment of migraine in our setting.

Abstract
OBJECTIVE To identify potential predictors of and factors associated with early neurologic deterioration (END) in primary intracerebral hemorrhage (ICH). METHODS Two hundred sixty-six patients with spontaneous supratentorial ICH admitted within 12 hours of stroke onset were investigated in a multicenter, prospective study. Sixty-one clinical, biochemical, and neuroimaging variables were registered on admission, and 37 clinical and neuroimaging variables were registered at 48 hours. The volumes of the ICH and peripheral edema on admission and at 48 hours were measured on CT scan. Stroke severity and functional outcome were evaluated with the Canadian Stroke Scale (CSS) and modified Rankin Scale. END was diagnosed when the CSS score decreased > or =1 points between admission and 48 hours. With use of logistic regression analyses, baseline variables that predicted END and factors measured after the early acute phase and associated with END were investigated. RESULTS END occurred in 61 (22.9%) patients. Body temperature of >37.5 degrees C (odds ratio [OR] 24.5; 95% CI 4.8 to 125), neutrophil count (by 1,000-unit increase; OR 2.1; 95% CI 1.6 to 2.6), and serum fibrinogen levels of >523 mg/dL (OR 5.6; 95% CI 1.9 to 16.2) on admission were independent predictors of END. Among the factors recorded at 48 hours, early ICH growth (OR 4.3; 95% CI 1.3 to 14.5), intraventricular bleeding (OR 2.6; 95% CI 1.4 to 5.0), and highest systolic blood pressure (by 10-unit increase; OR 1.17; 95% CI 1.02 to 1.32) were associated with END in multivariate analyses. CONCLUSIONS Clinical and biologic markers of the inflammatory reaction on admission are predictors of subsequent END, whereas early ICH growth, intraventricular bleeding, and high systolic blood pressure within 48 hours are factors associated with END in patients with spontaneous ICH.

Abstract
Matrix metalloproteinases (MMP) are a family of proteases involved in the remodelling of the extracellular matrix. In physiological conditions, the activity of MMP is regulated on several levels: gene transcription, activation of inactive precursors, and inhibition by endogenous factors. Loss of control and increased expression and activity of MMP have been implicated in various diseases (cancer, arthritis, vascular aneurysms, atherosclerosis, etc.). In the central nervous system, MMP are involved in the mechanisms associated with neuroinflammation, which is different in vascular and non-vascular diseases. MMP, especially MMP-9, have been shown to induce a high breakdown capacity, especially in the arteriolar basement membrane, leading to cerebral edema and secondary hemorrhage. In human clinical aspects, MMP are associated to intracerebral hemorrhage growth and with the development of complications in ischemic stroke. Combination therapies explicitly involving MMP inhibition could be of value in future treatment strategies.

Abstract
The use of experimental models is so common in most diseases, such as stroke, epilepsy or brain injury, that it does not seem to be necessary to justify in the study of experimental headache models. However, the study of these models was not been possible until 10-15 years ago. Two main reasons made it possible: first, increased basic knowledge about disease mechanisms in the last decade, a requirement necessary before models can be developed and validated; second, the publication of the headache classification of the International Headache Society in 1988 which has permitted an exact diagnosis, avoiding interobserver variability. This review examines the use of animal models to study the neurogenic inflammation described by Moskowitz and those used to study the vascular hypothesis. We have also examined the use of animal experiments to study the neurobiological basis for pain. Finally, we have explored the experimental human headache models not only in sufferers but also in healthy volunteers.

Abstract
INTRODUCTION The efficacy of current preventive migraine treatments is limited. In addition, tolerability problems are not infrequent. OBJECTIVES To check our experience with topiramate in the treatment of patients with refractory migraine. PATIENTS AND METHODS We offered treatment with topiramate to patients with the diagnosis of International Headache Society (IHS) migraine who had not responded to or tolerated beta-blockers, amitriptyline, flunarizine and/or valproate. This series is made up of 115 patients (88 women), between 16 and 81 years. Most of them (n=79) fulfilled the Silberstein et al. criteria for transformed migraine. The parameters analyzed were "response" (reduction in migraine frequency>50%), excellent response (>75%) and tolerability. RESULTS After 3 months, the maintenance doses of topiramate ranged from 25 to 400 mg, though most patients took 100 mg. Twenty-four (21%) patients withdrew due to adverse events, mostly cognitive difficulties, that had already occurred with doses as low as 25-50 mg, while 26 (23%) found topiramate ineffective. The remaining 65 (56%) patients responded, 34 with excellent response. Sixteen patients (10 obese) lost weight (3-13 kg). CONCLUSIONS Topiramate seems to be a good therapeutic option for about half of the patients with refractory migraine. In these patients response is usually excellent. Intolerance due to adverse events appears in one-fifth of the cases early and at low doses.

Abstract
BACKGROUND Almotriptan, the most recent drug of the triptan family, has shown good efficacy and tolerability profile in clinical trials. OBJECTIVE To assess almotriptan's tolerability and effectiveness in the setting of routine clinical practice. PATIENTS AND METHODS 1,643 patients diagnosed of migraine according to IHS criteria were recruited by 317 neurologists in the TEA 2000 study. Patients were instructed to report data on migraine attacks in a diary for a three months follow-up period. Data from 4,253 migraine attacks were obtained. RESULTS The incidence of adverse events was 0.02 per migraine attack (3,9 % of patients). Subjective clinical improvement after 30 minutes (33.2 y 37.1 %), pain improvement after 2 hours (65.5 % and 70.2 %), pain free response after 2 hours (26.6 % and 29.2 %), recurrence between 2 and 24 hours (21.2 % and 17 %) and a complete response by 24 hours (18.6 % and 22.9 %) were found. These results were obtained in both "intention to treat" and "per protocol" analyses, being even much better when only low pain intensity attacks were considered. CONCLUSIONS The TEA 2000 study results demonstrate good effectiveness and excellent tolerability profile of almotriptan 12.5 mg in the daily clinical neurological practice. The results of this study confirm those obtained in clinical trials carried out before almotriptan was introduced into the market and that it is a good therapeutic choice for the symptomatic treatment for migraine attacks.

Abstract
The mechanism for headache in patients with acute ischaemic stroke are not completely understood. We analysed the relationship between headache and the early worsening of neurological symptoms in patients with acute ischaemic stroke, and we studied the possible biochemical mechanisms implicated. Headache at the onset of ischaemic stroke predicted progression with a sensitivity, specificity, and positive predictive value of 56%, 99%, and 98%, respectively. CSF concentrations of glutamate, Interleukin-6, and NO-m were significantly greater in patients with progressing stroke than in patients with nonprogressing stroke, and these biochemical markers were also significantly higher in patients with headache than in those without headache. Results of this study suggest that headache at the onset of ischaemic stroke is an independent predictor of neurological worsening and we hypothesize that headache might be a surrogate marker of the molecular mechanisms involved in neurological worsening after acute stroke.

Abstract
BACKGROUND The mechanisms of cellular death in the tissue surrounding an intracerebral hemorrhage (ICH) are not defined. OBJECTIVE To investigate the relationship of markers of excitotoxicity and inflammation to brain injury after ICH. METHODS A total of 124 consecutive patients with spontaneous ICH admitted within 24 hours of stroke onset were prospectively investigated. The volumes of the initial ICH, peripheral edema on days 3 to 4, and the residual cavity at 3 months were measured on CT scan. Glutamate, cytokines, and adhesion molecules were measured in blood samples obtained on admission. Stroke severity and neurologic outcome were evaluated with the Canadian Stroke Scale. RESULTS Poor neurologic outcome at 3 months (Canadian Stroke Scale < 7) was observed in 53 patients (43%). Stroke severity and glutamate concentrations (by each increment of 10 micromol/L, odds ratio 1.23; 95% CI 1.09 to 1.41), but not the initial volume of ICH, were independent predictors of poor outcome. In the multiple linear regression analyses, tumor necrosis factor-alpha concentration was correlated (r = 0.83, p < 0.0001) with the volume of perihematoma edema, and glutamate concentrations were correlated (r = 0.78, p < 0.0001) with the volume of the residual cavity. These same results were observed when lobar (n = 58) and deep (n = 66) ICH were analyzed separately. CONCLUSIONS High plasma levels of proinflammatory molecules within 24 hours of intracerebral hemorrhage onset are correlated with the magnitude of the subsequent perihematoma brain edema, whereas poor neurologic outcome and the volume of the residual cavity are related to increased plasma glutamate concentrations.

Abstract
Understanding factors influencing patients' preference will improve guidance to make rational choices in expanded symptomatic migraine treatment. The objective of this open-label, cross-over study was to explore patients' preferences for sumatriptan 50 mg vs. zolmitriptan 2.5 mg tablets, focusing on factors influencing this preference. One hundred consecutive migraine patients attending our clinics were asked to treat three attacks with each medication and then fill out a preference questionnaire. Ninety-four migraineurs completed the trial and 42 (44%, 95% CI 34-58%) reported that they preferred zolmitriptan 2.5 mg over sumatriptan 50 mg tablets and 27 (29%, 20-38%) preferred sumatriptan 50 mg. The remaining 25 (27%, 18-36%) did not show any preference. For the initial treatment of the attacks, there were more patients needing just one tablet of zolmitriptan 2.5 mg compared with sumatriptan 50 mg (67 vs. 39%). The reasons for preference among those 69 patients who had shown preference for either of the two triptans were: a faster onset of action (speed of onset) (73%), a longer duration of the effects (39%), fewer adverse events (35%) and lower price (13%). Only one-quarter of the studied migraine population thought that sumatriptan 50 mg and zolmitriptan 2.5 mg were equivalent, which suggests that most migraine patients differentiate between triptans. A faster onset of action (speed of onset) was the most important reason for preference.

Abstract
The development of neurological deterioration in the hours following the stroke onset occurs in somewhat more than 1 in 3 cerebral infarcts and is associated with an increase in morbidity and mortality. This early deterioration (0--48/72 h) entails the conversion of the ischemic penumbra area in an irreversible lesion, a process that is mediated as much by hemodynamic changes in the local cerebral circulation as by biochemical mechanisms. Late neurological deterioration (3--7 days) is more frequently associated with systemic causes. Knowledge of the various clinical, biochemical and imaging markers associated with neurological deterioration is consequently of fundamental importance. For their repercussion in clinical practice, we classify these predictors of deteriorating cerebral infarct into nonmodifiable, modifiable and possibly modifiable. The reduction in cerebral blood flow in a particular cerebral zone causes very early cerebral damage as a consequence of a significant liberation of neuroexcitatory amino acids, followed by an excessive entry of calcium into the interior of cells; this process causes lipid peroxidation, disintegration of the cellular membranes, nuclear destruction and neuronal death. Moreover, ischemia and posterior reperfusion induce an inflammatory response leading to further cellular destruction. It is therefore conceivable that therapeutic interventions aimed at decreasing proinflammatory cytokines and cell adhesion molecules might result in better outcome in this population.

Abstract
We assessed the efficacy and safety of oral single doses of 0.5 and 1 g metamizol vs. 1 g acetylsalicylic acid (ASA) in 417 patients with moderate episodic tension-type headache included in a randomized, double-blind, placebo- and active-controlled, parallel, multicentre trial. Eligibility criteria included 18-65 years of age, history of at least two episodes of tension-type headache per month in the 3 months prior to enrollment, and successful previous pain relief with a non-opioid analgesic. Treatment arms were metamizol 0.5 g (n = 102), metamizol 1 g (n = 108), ASA 1 g (n = 102) and placebo (n = 105). The analgesic efficacy of 0.5 and 1 g metamizol vs. placebo was highly statistically significant (alpha: 0.025; one-sided) for sum of pain intensity differences, maximum pain intensity difference, number of patients with at least 50% pain reduction, time to 50% pain reduction, maximum pain relief and total pain relief. A trend towards an earlier onset of a more profound pain relief of 0.5 and 1 g metamizol over 1 g ASA was noticed. All medications including placebo were almost equally safe and well tolerated.

Abstract
BACKGROUND AND PURPOSE The mechanisms involved in the neurological deterioration of acute lacunar strokes are unknown. Although accumulating evidence suggests that glutamate release plays a role in the progression of territorial infarctions, it remains to be established whether excitotoxicity also participates in lacunar stroke progression. We investigated whether excitatory and inhibitory amino acid concentrations in blood predict subsequent progressive motor deficits in lacunar infarctions. METHODS We studied 113 consecutive patients with lacunar infarct, defined by clinical and computed tomography/magnetic resonance imaging criteria, within the first 24 hours after stroke onset. Neurological deterioration was defined as a decrease of >/=1 points in the motor items of the Canadian Stroke Scale in the first 48 hours after admission. Glutamate, glycine, and GABA were determined by high-performance liquid chromatography in plasma samples obtained on admission. Predictive values, sensitivity, specificity, and accuracy of specific glutamate and GABA concentrations and glutamatexglycine/GABA index for progression of lacunar stroke were calculated. RESULTS Twenty-seven patients (23.9%) had neurological worsening. Plasma concentrations of glutamate (253+/-70 versus 123+/-73 micromol/L, mean+/-SD) were higher and those of GABA (140+/-63 versus 411+/-97 nmol/L) were lower in the progressing group than in the nonprogressing group (both P<0.001). Glutamate concentrations >200 micromol/L and GABA levels <240 nmol/L had a positive predictive value for neurological deterioration of 67% and 84%, respectively. A excitotoxic index >106 had a positive predictive value of 85%. CONCLUSIONS These findings suggest that an imbalance between the glutamate and GABA concentrations may play a role in the pathophysiology of progressing lacunar infarctions.

Abstract
OBJECTIVES The response to the different antimigraine medications is variable. In this study we have analysed the profile of prescription of these antimigraine medications, both preventive and symptomatic, by a group of spanish neurologists and examined the subjective efficacy of these compounds. PATIENTS AND METHODS Neurologists from 7 hospitals in different spanish regions interviewed 305 patients (at least 40 per hospital) who met migraine diagnostic criteria. They used an ad hoc questionnaire in which the antimigraine medications, both symptomatic and preventive, taken by the patients, as well as their subjective response were registered. Patients with transformed migraine or tension-type headache more than 2 days per week were excluded. RESULTS Analgesics, non-steroidal anti-inflammatory drugs, ergotics and sumatriptan had been taken by 99, 69, 54 and 40% of the 305 interviewed patients, respectively. A subjective good response was refered to by 9% of patients who had taken analgesics, 23% of patients who had taken non-steroidal anti-inflammatory drugs, 39% of those who had taken ergotics and 63% of patients with sumatriptan. The current symptomatic treatment was: analgesics 34% of cases, non-steroidal anti-inflamatory drugs 26%, ergotics 13% and sumatriptan 63%. Regarding preventive treatments, 108 patients (35%) had been treated with calcium-antagonists, 87 (29%) with beta-blockers, 55 (18%) with amitriptyline and only 7 (2.2%) with valproic acid. The percentages of good responses to these drugs were: 55% for beta-blockers, 42% for calcium-antagonists and 31% for amitriptyline. CONCLUSIONS Our data confirm that analgesics are not efficacious in the majority of migraine patients and that the advent of sumatriptan has clearly improved the quality of migrane symptomatic treatment, even though about one-third of migraine patients do not respond to this drug. This study confirm that calcium-antagonists are the antimigraine preventive treatment most frequently prescribed in our country, even though their subjective efficacy is lower than that of beta-blockers.

Abstract
Zolmitriptan (previously known as 311C90) is a serotoninergic 5-HT1B/D agonist with high oral bioavailability with a double, central and peripheral, action mechanism. Evaluation of its clinical efficacy was developed in a program of clinical studies (search and confirmation of dosis, comparative and long term studies) and through analysis of efficacy in different clinical situations. Zolmitriptan shows a high effectiveness in the treatment of migraine crisis, significantly reduces the headaches by 2 hours of its administration, reduce the symptoms associated with migraine (nausea, photophobia and phonophobia) and improves the quality of life of the migraine patient. The efficacy is independent of the type of migraine characteristics of the patient as well as of the administration of other concomitant medications. The dosis of 2.5 mg of zolmitriptan has been found to be the optimum considering both efficacy and tolerability.

Abstract
BACKGROUND Migraine is the main reason for neurological consultation. OBJECTIVES To analyse the profile of the patient with migraine attending the Neurological Services of our country. PATIENTS AND METHODS Neurologists from 7 hospitals in different spanish regions interviewed 305 patients (at least 40 per hospital) who met migraine diagnostic criteria. They used an ad hoc questionnaire in which detailed demographic and migraine clinical data were included. Patients with transformed migraine or tension-type headache more than two days per week were excluded. RESULTS The majority (82%), were women, with no other diseases, with an average social (88%) and cultural (41%) level. The mean age at consultation was 38 +/- 11 years, while the mean duration of migraine history was 18 +/- 13 years; 78% met criteria of migraine without aura, 15% of migraine with aura and the remaining (8%) both migraine with and without aura criteria. Main subjective precipitating factors were: stress (80%), foods (68%), drugs (34%), alcohol (20%) and menstruation (8%). Migraine pain was referred to as mild by 4% of cases, as moderate by 59% and as severe in the remaining 37%. The usual duration of migraine attacks ranged from 12 to 24 h in 35% of cases, from 24 to 48 h in 25%, from 4 to 12 h in 23% and was longer than 48 h in the remaining 17%. More than half (53%) had more than 3 attacks per month. The pain was unilateral in 70% of cases, and more than half had vomiting (57%) and sono and/or photophobia (97%). CONCLUSIONS The typical profile of the migraine patient attending the Neurology Services in Spain is that of a woman aged from 20-50, with a long personal history of migraine, otherwise healthy and with an average socioeconomic and cultural level. Our data confirm that migraine attacks are incapacitating in a relevant number of these patients.

Abstract
Migraine is a risk factor for cerebral stroke, particularly in young women. Whether the migrainous process is a triggering or contributing factor in the ischemic profile, or is the sole cause of stroke, is impossible to establish with certainty. Epidemiological, pathophysiological and clinical evidence are in no way conclusive. The symptoms and lesions of migrainous stroke suggest the involvement of a mechanism similar to that of migrainous aura, although the infarction process is of greater intensity and lasts longer. Migrainous stroke should be considered an evolutionary complication of aura. Thus, the best treatment consists of adequate control of migraine attacks with the reduction of frequency, intensity and duration. The avoidance of migraine drugs with marked vasoconstrictive action, and the removal of other vascular risk factors (smoking and oral contraceptives) are additional measures for the prevention of migrainous stroke.

Abstract
This is the first large series, comprising 50 patients who suffered a total of 164 episodes, of pseudomigraine with temporary neurological symptoms and lymphocytic pleocytosis (PMP syndrome). Onset of PMP was between the ages of 14 and 39 years and was most frequent in males (68%). Eight males (24%) and five females (31%) had a personal history of migraine. One-quarter had had a viral-like illness up to 3 weeks prior to the onset of the syndrome. The clinical picture consisted of one to 12 episodes of changing variable neurological deficits accompanied by moderate-to-severe headache and occasionally fever. The headaches were described as predominantly throbbing and bilateral with variable duration (mean, 19 h). The mean duration of the transient neurological deficits was 5 h. Sensory symptoms were most common (78% of episodes), followed by aphasic (66%) and motor (56%) symptoms. Visual symptoms appeared in only 12% of episodes. The most frequent combinations were motor aphasia plus sensory and motor right hemibody symptoms (19% of episodes), motor aphasia plus right sensory symptoms (10%) and isolated right (9%) or left (9%) sensory symptoms. All patients were asymptomatic between episodes and following the symptomatic period (maximum duration 49 days). Lymphocytic pleocytosis ranged from 10 to 760 lymphocytic cells/mm3 CSF (mean, 199). In CSF, protein was increased in 96% of patients, IgG was normal in 80% of cases and oligoclonal bands were not found. Adensoine deaminase values were slightly above normal in two out of 16 patients tested. Extensive microbiological determinations, including viral HIV and borrelia serologies, were negative. Brain CT and MRI were always within normal limits, while EEG frequently showed focal slowing. Conventional cranial angiography was performed on 12 patients. In only one were there abnormalities suggestive of localized vascular inflammation, coincident with the focal neurological symptoms. Two patients developed PMP symptoms immediately after angiography. SPECT, performed on only three patients in the symptomatic period, revealed focal areas of decreased uptake consistent with the clinical symptoms. PMP aetiology remains a mystery; chronic arachnoiditis, viral meningoencephalitis or migraine are not plausible aetiological explanations. Because a number of patients had had a prodromic viral-like illness, we hypothesize here that such a viral infection could activate the immune system, thereby producing antibodies that would induce an aseptic inflammation of the leptomeningeal vasculature, possibly accounting for this clinical picture.

Abstract
Some foods in our diet can spark off migraine attacks in susceptible individuals. Some foods can bring an attack on through an allergic reaction. A certain number such as citrus fruits, tea, coffee, pork, chocolate, milk, nuts, vegetables and cola drinks have been cited as possible allergens associated with migraine. This mechanism has however been criticized: an improvement in symptoms by eliminating some food(s) from our diet does not necessarily mean an immunologically based allergic reaction. The high IgE incidence rate is not greater in such patients than in the population at large. Other allergic reactions unrelated to diet may also be associated with migraine attacks. On the other hand substances in food may be the cause of modifications in vascular tone and bring migraine on in those so prone. Among such substances are tyramine, phenylalanine, phenolic flavonoids, alcohol, food additives (sodium nitrate, monosodium glutamate, aspartame) and caffeine. Another recognized trigger for migraine is hypoglycemia. Such foods as chocolate, cheese, citrus fruits, bananas, nuts, 'cured' meats, dairy products, cereals, beans, hot dogs, pizza, food additives (sodium nitrate, monosodium glutamate in Chinese restaurant food, aspartame as a sweetener), coffee, tea, cola drinks, alcoholic drinks such as red wine, beer or whisky distilled in copper stills, all may bring on a migraine attack. For every patient we have to assess which foodstuffs are involved in the attack (not necessarily produced by consuming the product concerned) in order to try to avoid their consumptions as a means of prophylaxis for migraine.

Abstract
The connection between migraine and brain haemorrhage is controversial. We present the case of eight nonhypertense patients all aged under 57 with migraine antecedents who suffered brain haemorrhage during an attack. All underwent analytical study, chest X-ray, electrocardiography, computerized tomography scan and brain panangiography. The study was completed in six cases with an immunological analysis and in a further five with brain magnetic resonance. Seven patients habitually took vasoactive drugs to relieve migraine. The results do not show any other cause of brain haemorrhage. It is possible haemorrhage may be related to vascular lesion brought about by ischaemia secondary to vasospasms.
