Objective This internet survey aimed to analyze the activity of midolordecabeza.org, a specialized website for headache stakeholders. Background eHealth tools, such as websites, can be educational for stakeholders of a specific disease, such as patients. This is particularly helpful in chronic disorders such as migraine. eHealth also enhances patient-centered outcome research. The website midolordecabeza.org has the stated aim of organizing key information on headache making it accessible and useful for all stakeholders, and, eventually promoting patient participation. Methods We analyzed Google Analytics (GA) data to study the web's activity, traffic source, geographical distribution of access, registered-user behavior, electronic device performance, and temporary references with greater web activity. Results From January 2015 until December 2020, the website registered 1,121,585 visitors, 1,775,953 sessions, and a total of 3,833,144 views with an average time per session of nearly 2 min. Higher data traffic has been registered in Spanish-speaking countries such as Spain (33.3%; 591,256/1,775,953), where Spain's regions with higher views were statistically significantly correlated with the nationwide migraine prevalence (rho = 0.505; p = 0.039). In regard to social behavior, returning users were statistically significantly associated with being a woman (84.0%; 5696/6781), and they predominantly acceded from organic searches (50.6%; 3434/6781). When answering available open surveys, 72.5% (1827/2520) described their migraine as a disabling disease with high impact on their daily tasks and 64.4% (14,016/21,764) were unaware of what their headache diagnosis is. Conclusions Spanish-speaking patients with migraine around the world increasingly visited the headache-specialized website midolordecabeza.org using different electronic devices, showing great interest in their disease. This website allowed them to get updated information on their disease, share clinical data with physicians, and finally express their concerns.

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 10 EHF Congress, which took place in late June/early July 2020.

OnabotulinumtoxinA has been demonstrated to be effective as a preventive treatment in patients with chronic migraine (CM). Five years after the approval of onabotulinumtoxinA in Spain, the Headache Study Group of the Spanish Society of Neurology considered it worthwhile to gather a group of experts in treating patients with CM in order to draw up, based on current evidence and our own experience, a series of guidelines aimed at facilitating the use of the drug in daily clinical practice. For this purpose, we posed 12 questions that we ask ourselves as doctors, and which we are also asked by our patients. Each author responded to one question, and the document was then reviewed by everyone. We hope that this review will constitute a practical tool to help neurologists treating patients with CM.

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. Introducción: En los últimos a ̃nos se ha observado que moléculas como el péptido relacionado con el gen de la calcitonina (CGRP) y, en menor grado, el péptido activador de la adenilato- ciclasa pituitaria estaban elevadas durante los ataques de migra ̃na y en la migra ̃na crónica tanto en líquido cefalorraquídeo como en suero y que su reducción farmacológica tenía una significación clínica con una mejoría en la migra ̃na de los pacientes. Es lógico por tanto que una de las principales líneas de investigación en migra ̃na se base en el papel del CGRP en la fisiopatología de esta entidad. Desarrollo: Desde el Grupo de Estudio de Cefaleas de la Sociedad Espa ̃nola de Neurología nos planteamos la redacción de este documento, cuyo objetivo es abordar, basándonos en la evi- dencia publicada, cuestiones tan importantes como el papel del CGRP en la fisiopatología de la migra ̃na, el mecanismo de acción de los anticuerpos monoclonales y de los gepantes, el aná- lisis crítico de los resultados de los diferentes estudios, el perfil del paciente que podría ser candidato al tratamiento con anticuerpos monoclonales y su impacto en términos de farmacoe- conomía. Conclusiones: El desarrollo clínico de los gepantes, antagonistas del CGRP, para el tratamiento agudo del ataque de migra ̃na y de los anticuerpos monoclonales contra ligando y contra el receptor del CGRP ofrecen resultados esperanzadores para nuestros pacientes.

Background: Intracerebral haemorrhage growth is associated with poor clinical outcome and is a therapeutic target for improving outcome. We aimed to determine the absolute risk and predictors of intracerebral haemorrhage growth, develop and validate prediction models, and evaluate the added value of CT angiography. Methods: In a systematic review of OVID MEDLINE—with additional hand-searching of relevant studies' bibliographies— from Jan 1, 1970, to Dec 31, 2015, we identified observational cohorts and randomised trials with repeat scanning protocols that included at least ten patients with acute intracerebral haemorrhage. We sought individual patient-level data from corresponding authors for patients aged 18 years or older with data available from brain imaging initially done 0·5–24 h and repeated fewer than 6 days after symptom onset, who had baseline intracerebral haemorrhage volume of less than 150 mL, and did not undergo acute treatment that might reduce intracerebral haemorrhage volume. We estimated the absolute risk and predictors of the primary outcome of intracerebral haemorrhage growth (defined as >6 mL increase in intracerebral haemorrhage volume on repeat imaging) using multivariable logistic regression models in development and validation cohorts in four subgroups of patients, using a hierarchical approach: patients not taking anticoagulant therapy at intracerebral haemorrhage onset (who constituted the largest subgroup), patients taking anticoagulant therapy at intracerebral haemorrhage onset, patients from cohorts that included at least some patients taking anticoagulant therapy at intracerebral haemorrhage onset, and patients for whom both information about anticoagulant therapy at intracerebral haemorrhage onset and spot sign on acute CT angiography were known. Findings: Of 4191 studies identified, 77 were eligible for inclusion. Overall, 36 (47%) cohorts provided data on 5435 eligible patients. 5076 of these patients were not taking anticoagulant therapy at symptom onset (median age 67 years, IQR 56–76), of whom 1009 (20%) had intracerebral haemorrhage growth. Multivariable models of patients with data on antiplatelet therapy use, data on anticoagulant therapy use, and assessment of CT angiography spot sign at symptom onset showed that time from symptom onset to baseline imaging (odds ratio 0·50, 95% CI 0·36–0·70; p

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.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.

Background Intravenous thrombolysis with alteplase is the only approved treatment for acute ischemic stroke, but its efficacy and safety when administered more than 3 hours after the onset of symptoms have not been established. We tested the efficacy and safety of alteplase administered between 3 and 4.5 hours after the onset of a stroke. Methods After exclusion of patients with a brain hemorrhage or major infarction, as detected on a computed tomographic scan, we randomly assigned patients with acute ischemic stroke in a 1:1 double-blind fashion to receive treatment with intravenous alteplase (0.9 mg per kilogram of body weight) or placebo. The primary end point was disability at 90 days, dichotomized as a favorable outcome (a score of 0 or 1 on the modified Rankin scale, which has a range of 0 to 6, with 0 indicating no symptoms at all and 6 indicating death) or an unfavorable outcome (a score of 2 to 6 on the modified Rankin scale). The secondary end point was a global outcome analysis of four neurologic and disability scores combined. Safety end points included death, symptomatic intracranial hemorrhage, and other serious adverse events. Results We enrolled a total of 821 patients in the study and randomly assigned 418 to the alteplase group and 403 to the placebo group. The median time for the administration of alteplase was 3 hours 59 minutes. More patients had a favorable outcome with alte plase than with placebo (52.4% vs. 45.2%; odds ratio, 1.34; 95% confidence interval [CI], 1.02 to 1.76; P = 0.04). In the global analysis, the outcome was also improved with alteplase as compared with placebo (odds ratio, 1.28; 95% CI, 1.00 to 1.65; P

The efficacy of current preventive migraine treatments is limited. In addition, tolerability problems are not infrequent.To check our experience with topiramate in the treatment of patients with refractory migraine.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 frequency50%), excellent response (75%) and tolerability.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).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.
