Nummular headache (NH) is a primary headache characterized by superficial coin-shaped pain. NUMITOR (NCT 05475769) is an observational study evaluating the responder rate of preventive drugs in NH patients. The treatment response was assessed between weeks 8 and 12 compared with the baseline. Patients were included between February 2002 and October 2022. Demographic and clinical variables were assessed; treatment response was estimated by 50%, 30%, and 75% responder rates and treatment discontinuation due to inadequate tolerability. A total of 183 out of 282 patients fulfilled eligibility criteria and completed the study. Patients were aged 49.5 (standard deviation (SD): 16.8) years, and 60.7% were female. NH phenotype was a parietal circular pain of four centimeters’ diameter, moderate intensity, and oppressive quality. At baseline, patients had 25 (interquartile range) pain days per month. Preventive treatment was used by 114 (62.3%) patients. The highest 50% and 75% responder rates corresponded to onabotulinumtoxinA (62.5%, 47.5%), followed by gabapentin (43.7%, 35.2%). Oral preventive drugs were not tolerated by 12.9–25%. The present study provides class IV evidence of the effectiveness of oral preventive drugs and onabotulinumtoxinA in the treatment of primary NH. OnabotulinumtoxinA was the most effective and best-tolerated drug, positioning it as first-line treatment of NH.

Métodos Neurólogos del Grupo de Cefaleas de la Sociedad Española de Neurología (SEN) y neurocirujanos expertos en neurocirugía funcional seleccionados por la Sociedad Española de Neurocirugía (SENEC), hemos realizado una revisión exhaustiva en el sistema Medline sobre neuromodulación en cefaleas y neuralgias. Resultados Presentamos una revisión actualizada y establecemos por primera vez unas recomendaciones consensuadas entre la SEN y la SENEC sobre el uso de la neuromodulación en cefaleas y neuralgias, adjudicando niveles de evidencia sobre su eficacia actual, específicamente en cada entidad nosológica. Conclusiones Los resultados actuales de los estudios proporcionan evidencias para la indicación de técnicas de neuromodulación en casos refractarios de cefaleas y neuralgias (sobre todo en migraña, cefalea en racimos y neuralgia del trigémino), seleccionados por neurólogos expertos en cefaleas, tras comprobar el agotamiento de las opciones farmacológicas. Adicionalmente, en el caso de la neuromodulación invasiva, se recomienda que los casos sean debatidos en comités multidisciplinarios y la cirugía sea realizada por equipos de neurocirujanos expertos en neurocirugía funcional y con una morbimortalidad aceptable. Introduction Numerous invasive and non-invasive neuromodulation devices have been developed and applied to patients with headache and neuralgia in recent years. However, no updated review addresses their safety and efficacy, and no healthcare institution has issued specific recommendations on their use for these 2 conditions. Methods Neurologists from the Spanish Society of Neurology's (SEN) Headache Study Group and neurosurgeons specialising in functional neurosurgery, selected by the Spanish Society of Neurosurgery (SENEC), performed a comprehensive review of articles on the MEDLINE database addressing the use of the technique in patients with headache and neuralgia. Results We present an updated review and establish the first set of consensus recommendations of the SEN and SENC on the use of neuromodulation to treat headache and neuralgia, analysing the current levels of evidence on its effectiveness for each specific condition. Conclusions Current evidence supports the indication of neuromodulation techniques for patients with refractory headache and neuralgia (especially migraine, cluster headache, and trigeminal neuralgia) selected by neurologists and headache specialists, after pharmacological treatment options are exhausted. Furthermore, we recommend that invasive neuromodulation be debated by multidisciplinary committees, and that the procedure be performed by teams of neurosurgeons specialising in functional neurosurgery, with acceptable rates of morbidity and mortality.

Background and purposeSpain has been heavily affected by COVID-19. Reallocation of resources for managing the outbreak might have caused a disruption in stroke care. This study analyses the impact on stroke care of reorganising the healthcare system in response to the first COVID-19 outbreak peak in Spain and the strategies adopted by Spanish stroke units to deal with this impact.Materials and methodsWe obtained data from a structured survey sent to the responsible of stroke units across the country. We recorded the number of strokes, stroke code activations, intravenous thrombolysis treatments and mechanical thrombectomies during February and March 2019 and 2020. We also collected information on the impact on workflow metrics and on the availability of specialised neurological care and rehabilitation treatments, the characteristics of stroke care for patients with SARS-CoV-2 infection and the impact on human resources. We compared the activity data between 2019 and 2020 and the information on activity and impact on stroke care between regions classified according to the disease incidence rate.ResultsFifty-seven (75%) of all stroke units in Spain responded to the survey. There was an overall reduction in admissions for all stroke types during the outbreak’s peak and in the number of stroke code activations and intravenous thrombolysis treatments, results that were independent of the COVID-19 incidence rate. Participants reported a delay in workflow metrics and a reduction of admissions to stroke units, outpatient clinics and rehabilitation therapies. Specific pathways and protocols for managing stroke patients with SARS-CoV-2 infection have been established.ConclusionThe COVID-19 outbreak has jeopardised all phases of stroke care. As a consequence, some patients with stroke did not receive adequate treatment.

Background Recently, amylin and its receptors were found in different structures involved in migraine pathophysiology. Here, we evaluate interictal concentrations of amylin and calcitonin gene-related peptide in peripheral blood as biomarkers for chronic migraine. Methods We prospectively recruited patients with episodic migraine, chronic migraine and healthy controls. Interictal amylin and calcitonin gene-related peptide levels were assessed in blood samples using enzyme linked immunosorbent assay. Results We assessed plasma samples from 58 patients with episodic migraine (mean age 37.71 ± 10.47, 87.9% female), 191 with chronic migraine (mean age 46.03 ± 11.93, 95% female), and on 68 healthy controls (mean age 43.58 ± 11.08 years, 86% female). Body mass index was 25.94 ± 4.53 kg/m2 for migraine patients and 25.13 ± 4.92 kg/m2 for healthy controls ( p = 0.0683). Interictal plasma amylin levels were higher in chronic migraine patients (47.1 pg/mL) than in the episodic migraine patients (28.84 pg/mL, p Conclusion Interictal plasma amylin levels are higher in patients with chronic migraine and may serve as a diagnostic biomarker for chronic migraine.

Background Migraine represents a serious burden for national health systems. However, preventive treatment is not optimally applied to reduce the severity and frequency of headache attacks and the related expenses. Our aim was to assess the persistence to traditional migraine prophylaxis available in Spain and its relationship with the healthcare resource use (HRU) and costs. Methods Retrospective observational study with retrospective cohort design of individuals with migraine treated with oral preventive medication for the first time from 01/01/2016 to 30/06/2018. One-year follow-up information was retrieved from the Big-Pac™ database. According to their one-year persistence to oral prophylaxis, two study groups were created and describe regarding HRU and healthcare direct and indirect costs using 95% confidence intervals (CI). The analysis of covariance (ANCOVA) was performed as a sensitivity analysis. Patients were considered persistent if they continued on preventive treatment until the end of the study or switched medications within 60 days or less since the last prescription. Non-persistent were those who permanently discontinued or re-initiated a treatment after 60 days. Results Seven thousand eight hundred sixty-six patients started preventive treatment (mean age (SD) 48.2 (14.8) and 80.4% women), of whom 2,545 (32.4%) were persistent for 6 months and 2,390 (30.4%) for 12 months. Most used first-line preventive treatments were antidepressants (3,642; 46.3%) followed by antiepileptics (1,738; 22.1%) and beta-blockers (1,399; 17.8%). The acute treatments prescribed concomitantly with preventives were NSAIDs (4,530; 57.6%), followed by triptans (2,217; 28.2%). First-time preventive treatment prescribers were mostly primary care physicians (6,044; 76.8%) followed by neurologists (1,221; 15.5%). Non-persistent patients required a higher number of primary care visits (mean difference (95%CI): 3.0 (2.6;3.4)) and days of sick leave (2.7 (0.8;4.5)) than the persistent ones. The mean annual expenditure was €622 (415; 829) higher in patients who not persisted on migraine prophylactic treatment. Conclusions In this study, we observed a high discontinuation rate for migraine prophylaxis which is related to an increase in HRU and costs for non-persistent patients. These results suggest that the treatment adherence implies not only a clinical benefit but also a reduction in HRU and costs.

Resumen: OnabotulinumtoxinA ha demostrado ser eficaz como tratamiento preventivo en pacientes con migraña crónica (MC). El Grupo de Estudio de Cefalea de la Sociedad Española de Neurología ha considerado que sería de interés, a los 5 años de la aprobación en España de la onabotulinumtoxinA, reunir a un grupo de expertos en el tratamiento de pacientes con MC para elaborar con la evidencia actual y nuestra experiencia unas recomendaciones dirigidas a facilitar su uso en la práctica clínica diaria. Con este fin planteamos 12 preguntas que nos hacemos como médicos y que también nos realizan nuestros pacientes. Cada autor ha contestado una pregunta y luego el documento ha sido revisado por todos. Esperamos que esta revisión constituya una herramienta práctica para ayudar a los neurólogos que tratan a pacientes con MC. Abstract: 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.

Resumen Introduccion La pandemia COVID-19 ha provocado un inusitado impulso a la telemedicina (TM). Analizamos el impacto de la pandemia en la TM aplicada en las consultas de cefaleas espanolas, revisamos la literatura y lanzamos unas recomendaciones para implantar la TM en las consultas. Metodo Tres fases: 1) Revision de la base Medline desde el ano 1958 (primera experiencia de TM); 2) Formulario Google Forms enviado a todos los neurologos del Grupo de Estudio de Cefaleas de la Sociedad Espanola de Neurologia (GECSEN), y 3) Consenso on-line de expertos GECSEN para emitir recomendaciones para implantar la TM en Espana. Resultados La pandemia por COVID-19 ha empeorado los tiempos de espera presenciales, incrementando el uso de todas las modalidades de TM antes y despues de abril de 2020: telefono fijo (del 75% al 97%), telefono movil (del 9% al 27%), correo electronico (del 30% al 36%) y videoconsulta (del 3% al 21%). Los neurologos son conscientes de la necesidad de ampliar la oferta con videoconsultas, claramente in crescendo, y otras herramientas de e-health y m-health. Conclusiones Desde el GECSEN recomendamos y animamos a todos los neurologos que asisten a pacientes con cefaleas a implantar recursos de TM, teniendo como objetivo optimo la videoconsulta en menores de 60-65 anos y la llamada telefonica en mayores, si bien cada caso debe individualizarse. Se debera contar previamente con la aprobacion y asesoramiento de los servicios juridicos e informaticos y de la direccion del centro. La mayoria de los pacientes con cefalea y/o neuralgia estable son candidatos a seguimiento mediante TM, tras una primera visita que tiene que ser siempre presencial.

Background Erenumab was approved in Europe for migraine prevention in patients with ≥4 monthly migraine days (MMD). In Spain, Novartis started a personalized managed access program which allowed free access to erenumab before official reimbursement. The Headache Study Group of the Spanish Neurological Society started a registry to monitor real-world safety and efficacy, and all Spanish headache experts were invited to participate. Methods Patients fulfilled ICHD3 criteria for migraine and had ≥ 4MMD. Sociodemographic and clinical data were registered as well as MMD, headache frequency (MHD), prior and concomitant preventive treatment, medication overuse headache (MOH), migraine evolution, adverse events, and PROs: HIT6, MIDAS, and PGIC. A >50% reduction of MMD after 3 months was considered as response. Results We included 210 patients (female 86.7%, mean age 46.4 years old) from 22 hospitals from February 2019 – to – June 2020. Most patients (89.5%) suffered from chronic migraine with a mean evolution of 8.6 years. MOH was present in 70% of patients, and 17.1% had migraine with aura. Average of prior preventive treatment failure was >7 (BoNT/A had been used by 95.2%). Most patients (67,6%) started with erenumab 70mg. 61% of patients were also taking oral preventive drugs or getting simultaneous BoNT/A (27.6%). Responder rate was 37.1% and the mean reduction of MMD was -6.28 and MHD: -8.6. Regarding PROs: MIDAS: -35 p., HIT6: -11.6 p., PIGC: 4.7 p. Predictors of good response were: HIT6 score ( p =0.01), prior preventive treatment failures ( p =0.026), absence of MOH ( p =0.039), and simultaneous BoNT/A treatment ( p

Neurociència; Psicologia Neurociencia; Psicología Neuroscience; Psychology Identifying highly disabled patients or at high risk of psychiatric comorbidity is crucial for migraine management. The burden of migraine increases with headache frequency, but the number of headache days (HDs) per month after which disability becomes severe or the risk of anxiety and depression is higher has not been established. Here, we estimate the number of HDs per month after which migraine is associated with higher risk of anxiety and depression, severe disability and lower quality of life. We analysed 468 migraine patients (mean age 36.8 ± 10.7; 90.2% female), of whom 38.5% had ≥ 15 HDs per month. Our results show a positive linear correlation between the number of HDs per month and the risk of anxiety (r = 0.273; p

Tratamiento preventivo; Cefalea con uso excesivo de medicación; Opioides Tractament preventiu; Cefalea per ús excessiu de medicaments; Opioides Preventive treatment; Medication overuse headache; Opioids Introducción La cefalea con uso excesivo de medicación es una cefalea secundaria en la que el uso regular o frecuente de medicación analgésica produce un aumento de la frecuencia de una cefalea de base, pasando de episódica a crónica. La prevalencia de esta entidad está en torno al 1-2%, siendo más frecuente en mujeres entre 30 y 50 años con comorbilidades psiquiátricas como depresión o ansiedad y otros procesos de dolor crónico. Es importante conocer el manejo de esta entidad. Por este motivo, el Grupo de Estudios de Cefaleas de la Sociedad Española de Neurología ha pretendido realizar este documento de consenso sobre esta patología. Desarrollo Esta guía ha sido redactada por un grupo de expertos a partir de la revisión de la evidencia científica publicada y estableciendo recomendaciones prácticas para su adecuado manejo y tratamiento. El tratamiento de la cefalea con uso excesivo de medicación tiene varios pilares fundamentales y suele ser complejo: información y educación sobre el desarrollo de la cefalea con uso excesivo de medicación, tratamiento preventivo, suspensión del fármaco de uso frecuente y tratamiento de deshabituación. Es importante el seguimiento de pacientes con riesgo de recurrencias. Conclusiones Esperamos que este documento resulte de utilidad y permita su aplicación práctica en la consulta diaria y que sirva para actualizar y mejorar el conocimiento del manejo de esta patología. Introduction Medication overuse headache is a secondary headache in which the regular or frequent use of analgesics can increase the frequency of the episodes, causing the transition from episodic to chronic headache. The prevalence of medication overuse headache is approximately 1-2%, with higher rates among women aged 30-50 years and with comorbid psychiatric disorders such as depression or anxiety, or other chronic pain disorders. It is important to be familiar with the management of this disease. To this end, the Spanish Society of Neurology's Headache Study Group has prepared a consensus document addressing this disorder. Development These guidelines were prepared by a group of neurologists specialising in headache after a systematic literature review and provides consensus recommendations on the proper management and treatment of medication overuse headache. The treatment of medication overuse headache is often complex, and is based on 4 fundamental pillars: education and information about the condition, preventive treatment, discontinuation of the drug being overused, and treatment for withdrawal symptoms. Follow-up of patients at risk of recurrence is important. Conclusions We hope that this document will be useful in daily clinical practice and that it will update and improve understanding of medication overuse headache management.

To compare the cost of adverse events (AEs) associated with preventive treatment of migraine with fremanezumab, versus erenumab, galcanezumab, and onabotulinumtoxinA. A probabilistic modeling analy...

BACKGROUND: OnabotulinumtoxinA is an effective preventive treatment for chronic migraine. In chronic migraine, besides a reduction in headache frequency, a decreased reliance on oral prophylactics is also indicative of treatment effectiveness. This study aimed to quantify the change in the use of oral prophylactics after treatment with onabotulinumtoxinA in patients with chronic migraine.; METHODS: This was a retrospective, multicentric, cross-sectional study. Patients with chronic migraine (ICHD-3b) that had been treated with onabotulinumtoxinA were enrolled consecutively. We collected parameters related to each patient's pre-treatment situation, as well as their current one, focusing on frequency and intensity of migraine, number of oral prophylactics and the respective cycle of onabotulinumtoxinA. Univariate and logistic regression analyses were performed.; RESULTS: We included 542 patients. 90.0% were taking oral preventive treatments. During treatment with onabotulinumtoxinA, 47.8% withdrew at least one prophylactic and 41.6% stopped using oral prophylactics altogether. Factors associated with a reduction or cessations of oral prophylactics were: having>50% improvement in frequency and intensity, remission to episodic migraine, the use of topiramate as an initial treatment, an increased number of infiltrations and a shorter chronification period (pfive cycles of onabotulinumtoxinA, >50% improvement in pain intensity and topiramate as an initial treatment were predictors of a reduction in oral prophylactics (AUC of 70.3%; p

Objective To identify factors associated with poor anticoagulation control with vitamin K antagonists (VKA) among outpatients with nonvalvular atrial fibrillation (NVAF) attended in Neurology and Internal Medicine in Spain. Methods Cross-sectional and multicenter study, from the ALADIN database, of outpatients with NVAF treated with VKA and attended in Internal Medicine and Neurology in Spain. Rates of anticoagulation control were determined with the direct and Rosendaal methods, considering data from the 6 months before the inclusion. Results Out of 1337 patients included in the ALADIN study, 750 were taking VKA, and complete information about INR values in the last 6 months was available in 383 patients. Mean scores of Charlson Index, CHADS2, CHA2DS2-VASc and HAS-BLED were 1.94 ± 1.54; 3.10 ± 1.26; 4.63 ± 1.54, and 2.20 ± 0.90, respectively. 46.2% and 47.0% of patients had an adequate anticoagulation control according to the direct and Rosendaal methods, respectively. Inadequate anticoagulation control according to the direct method was associated with diabetes (OR: 2.511; 95% CI: 1.144–5.659), prior labile INR (OR: 35.371; 95% CI: 15.058–83.083) and the determination of >6 INR controls in the last 6 months (OR: 4.747; 95% CI: 2.094–10.759), and according to the Rosendaal method, with prior labile INR (p Conclusions Despite the high thromboembolic risk, only a little more than a half of patients were well controlled. Factors associated with poor anticoagulation control were diabetes, labile INR, >6 INR controls and HAS-BLED.

Metodos Estudio transversal, multicentrico, anidado en el estudio ALADIN, de sujetos con FANV, tratados con AVK, atendidos en consultas de Medicina Interna o Neurologia de Espana. El grado de control de la anticoagulacion se estudio mediante el metodo directo y el de Rosendaal, considerando los 6 meses previos a la inclusion. Resultados De los 1.337 pacientes incluidos en ALADIN, 750 estaban tratados con AVK, con informacion completa sobre el INR de los ultimos 6 meses en 383 pacientes. Las puntuaciones medias del indice de Charlson, CHADS2, CHA2DS2-VASc y HAS-BLED fueron 1,94 ± 1,54; 3,10 ± 1,26; 4,63 ± 1,54 y 2,20 ± 0,90, respectivamente. El 46,2% y el 47,0% de los pacientes presentaban un control adecuado de la anticoagulacion por los metodos directo y Rosendaal, respectivamente. El control inadecuado de la anticoagulacion se asocio por el metodo directo con diabetes (OR: 2,511; IC 95%: 1,144-5,659), antecedentes de INR inestable (OR: 35,371; IC 95%: 15,058-83,083) y la realizacion de > 6 controles en los ultimos 6 meses (OR: 4,747; IC 95%: 2,094-10,759), y por el metodo de Rosendaal, con los antecedentes de INR inestable (p Conclusiones Pese al alto riesgo tromboembolico, solo estaban bien controlados algo mas de la mitad. Los factores asociados al mal control de la anticoagulacion fueron la diabetes, INR inestable, > 6 controles de INR y el HAS-BLED.

ResumenIntroduccion y objetivos Actualmente hay cada vez mas interes en el tejido adiposo epicardico (TAE) como marcador de enfermedad cardiovascular. Nuestro objetivo es describir el TAE medido por ecocardiograma, y determinar su asociacion con el sindrome metabolico (SM), dentro del estudio poblacional RIVANA. Metodos Se incluyo a 880 sujetos de 45 a 74 anos (492 con SM segun la definicion armonizada). Se realizo una exploracion fisica y se tomo una muestra sanguinea para obtener el perfil bioquimico. Se midio el espesor del TAE con ecocardiografia transtoracica al final de la sistole. Resultados Entre los sujetos sin SM, la prevalencia de TAE ≥ 5 mm aumentaba significativamente con la edad (> 65 frente a 45–54 anos, OR = 8,22; IC95%, 3,90-17,35; p lineal

Background Major adverse cardiovascular events are the main cause of morbidity and mortality over the long term in patients undergoing carotid endarterectomy. There are few reports assessing the prognostic value of markers of inflammation in relation to the risk of cardiovascular disease after carotid endarterectomy. Here, we aimed to determine whether matrix metalloproteinases (MMP-1, MMP-2, MMP-7, MMP-9 and MMP-10), tissue inhibitor of MMPs (TIMP-1) and in vivo inflammation studied by 18F-FDG-PET/CT predict recurrent cardiovascular events in patients with carotid stenosis who underwent endarterectomy. Methods This prospective cohort study was carried out on 31 consecutive patients with symptomatic (23/31) or asymptomatic (8/31) severe (> 70%) carotid stenosis who were scheduled for carotid endarterectomy between July 2013 and March 2016. In addition, 26 healthy controls were included in the study. Plasma and serum samples were collected 2 days prior to surgery and tested for MMP-1, MMP-2, MMP-7, MMP-9, MMP-10, TIMP-1, high-density lipoprotein, low-density lipoprotein, high-sensitivity C-reactive protein and erythrocyte sedimentation rate. 18F-FDG-PET/CT focusing on several territories’ vascular wall metabolism was performed on 29 of the patients because of no presurgical availability in 2 symptomatic patients. Histological and immunohistochemical studies were performed with antibodies targeting MMP-10, MMP-9, TIMP-1 and CD68. Results The patients with carotid stenosis had significantly more circulating MMP-1, MMP-7 and MMP-10 than the healthy controls. Intraplaque TIMP-1 was correlated with its plasma level (r = 0.42 P = .02) and with 18F-FDG uptake (r = 0.38 P = .05). We did not find any correlation between circulating MMPs and in vivo carotid plaque metabolism assessed by 18F-FDG-PET. After a median follow-up of 1077 days, 4 cerebrovascular, 7 cardiovascular and 11 peripheral vascular events requiring hospitalization were registered. Circulating MMP-7 was capable of predicting events over and above the traditional risk factors (HR = 1.15 P = .006). When the model was associated with the variables of interest, the risk predicted by 18F-FDG-PET was not significant. Conclusions Circulating MMP-7 may represent a novel marker for recurrent cardiovascular events in patients with moderate to severe carotid stenosis. MMP-7 may reflect the atherosclerotic burden but not plaque inflammation in this specific vascular territory.

Background and purpose: Migraine is a common and costly neurological disorder. The aims of this study were to quantify the costs of chronic (CM) and episodic migraine (EM) in Spain, evaluating the impact of psychiatric comorbidities and disability, and to estimate the economic savings associated with reducing the number of migraine-days by 50%. Methods: This was an observational, cross-sectional analysis of data from migraine patients who participated in the Spanish Migraine Atlas. The participants were invited to complete a structured questionnaire including the following scales: the Headache Needs Assessment, the Hospital Anxiety and Depression Scale, and the Migraine Disability Assessment Scale (MIDAS). Results: A total of 475 patients were included, of whom 187 had CM (39.4%). Total costs per patient/year were: €16 578.2 ± €34 568.1 for CM and €6227.8 ± €6515.7 for EM. A higher degree of disability, according to MIDAS, significantly increased the total cost of migraine, while the presence of psychiatric comorbidity increased costs for EM patients only. A reduction of 1 migraine-day per month decreased average total costs by €744.14 per patient/year for EM and €663.20 per patient/year for CM, while a reduction in the number of migraine-days by 50% would result in economic savings of €2232.44 per patient/year (R2 = 0.927) for EM and €6631.99 per patient/year (R2 = 0.886) for CM. Conclusions: The costs associated with migraine were driven by migraine frequency and the degree of disability, whereas psychiatric comorbidity only influenced the cost of EM. These results highlight the need to optimize migraine management to reduce the economic migraine burden. Future studies are needed to confirm our results.

Resumen: Introducción: En el campo de las cefaleas, onabotulinumtoxinA (onabotA) tiene indicación bien establecida en la migraña crónica (MC). Además, en los últimos años su uso se está extendiendo a otras cefaleas primarias (migraña episódica de alta frecuencia, cefaleas trigémino-autonómicas, cefalea numular) y a la neuralgia del trigémino. Al ser una opción terapéutica que se va a ir incorporando de forma progresiva en el manejo de estas entidades, creemos que es necesario reflejar con un carácter eminentemente práctico cuáles son las posibles indicaciones de onabotA, más allá de la MC, así como su protocolo de administración, que diferirá en función del tipo de cefalea y/o neuralgia. Desarrollo: A partir de una revisión de la bibliografía existente y de nuestra propia experiencia clínica, se ha elaborado este documento de consenso cuyo objetivo es servir de guía a aquellos profesionales que quieran aplicar estas técnicas en su actividad asistencial. En la primera parte se abordará el mecanismo de acción de onabotA y la razón de su utilización en diversas cefaleas distintas de la MC desde un punto de vista fisiopatológico y clínico. En la segunda parte se hará una revisión de la evidencia disponible y los estudios publicados en los últimos años. Para cada una de estas entidades, se añadirá una «recomendación de experto», basada en la propia experiencia clínica, que refleje el perfil de paciente que puede ser candidato a este tratamiento, las dosis y el protocolo de administración de onabotA. Conclusión: El tratamiento con onabotA en entidades distintas a la MC debe ser siempre individualizado y se planteará en pacientes seleccionados que no hayan respondido a la terapia convencional. Abstract: Introduction: In the field of headaches, onabotulinumtoxinA (onabotA) is well established as a treatment for chronic migraine (CM). In recent years, it has been used increasingly to treat other primary headaches (high-frequency episodic migraine, trigeminal-autonomic cephalalgias, nummular headache) and trigeminal neuralgia. As this treatment will progressively be incorporated in the management of these patients, we consider it necessary to reflect, with a fundamentally practical approach, on the possible indications of onabotA, beyond CM, as well as its administration protocol, which will differ according to the type of headache and/or neuralgia. Development: This consensus document was drafted based on a thorough review and analysis of the existing literature and our own clinical experience. The aim of the document is to serve as guidelines for professionals administering onabotA treatment. The first part will address onabotA's mechanism of action, and reasons for its use in other types of headache, from a physiopathological and clinical perspective. In the second part, we will review the available evidence and studies published in recent years. We will add an “expert recommendation” based on our own clinical experience, showing the best patient profile for this treatment and the most adequate dose and administration protocol. Conclusion: Treatment with onabotA should always be individualised and considered in selected patients who have not responded to conventional therapy.

Background There are only four previous pediatric reports of the glossopharyngeal neuralgic form of the stylohyoid complex syndrome. Stylohyoid complex has merely been described as cases of glossopharyngeal neuralgia in children. Case Report A 12-year-old boy came to our hospital because of recurrent episodes of severe cranial pain (9/10) lasting for 5 to 15 minutes. Pain affected the right tonsillar fossa, ear, and mastoid region. Since the start at the age of 9 years, the frequency of painful episodes has progressively increased: when admitted to our clinics 3 years later, the child was having up to five episodes daily in spite of analgesic, antiepileptic, and antidepressant drugs; he had abandoned school and leisure. Between episodes, neurological examination detected only discomfort to pressure on the right tonsillar fossa. Three-dimensional computed tomography images of the skull base showed an elongated right styloid process and bilateral calcification of the stylohyoid ligament. After surgical excision of the right styloid process and of part of the stylohyoid ligament, the glossopharyngeal painful episodes ceased. The patient remains asymptomatic seven years later. Conclusion In spite of its rarity in childhood, this debilitating but treatable syndrome should be kept in mind for the differential diagnosis of recurrent cranial pain in the pediatric population.

Introduccion. Tras la celebracion del congreso de la European Headache Federation (EHF), reconocidos neurologos espanoles expertos en el tratamiento de la migrana expusieron en la Reunion Post-EHF las principales novedades presentadas en el congreso y relacionadas con ese ambito. Desarrollo. Se abordan los principales datos presentados relacionados con el tratamiento de la migrana cronica y episodica; concretamente, los relacionados con los tratamientos preventivos y la experiencia en vida real en el manejo de la enfermedad. Se hizo una importante revision de las nuevas dianas terapeuticas y las posibilidades que ofrecen en cuanto al conocimiento de la fisiopatologia de la migrana y su tratamiento. Asimismo, se hizo una actualizacion de las novedades presentadas en el tratamiento de la migrana con fremanezumab, anticuerpo monoclonal recientemente autorizado por la Agencia Europea de Medicamentos. Se hizo una actualizacion de las novedades en investigacion basica en la patologia, asi como una relacion de los sintomas de migrana y COVID-19. Finalmente, se abordaron las implicaciones de la migrana en la carga sanitaria asistencial y economica, y su impacto en la sociedad. Conclusiones. En la reunion se hizo un resumen del contenido presentado en el 14 Congreso de la EHF, que tuvo lugar a finales de junio y principios de julio de 2020.

Background Localized facial scleroderma usually presents as frontal linear morphea or progressive hemifacial atrophy. Only isolated cases of trigeminal painful neuropathy have been described. Case report A 43-year-old woman developed an oval lesion on the right cheek. After 1 year, she noticed constant “pulling” pain and episodes of lancinating pain, both spontaneous and triggered by chewing and cold drinks. She was diagnosed with solitary morphea profunda and CT scan, ultrasonography, cranial MRI and biopsy were completed. Methylprednisolone (1 gr/day for 3 days) was prescribed. For pain, gabapentin, oxcarbazepine, amitryptiline, pregabalin and eslicarbacepine were all ineffective. A capsaicin patch was placed with prolonged benefit. Later on, the pain slightly worsened; occipital blockade was effective and methotrexate was recommended. Conclusion This is the first case of solitary morphea profunda associated with painful trigeminal neuropathy. Treatment should include immunosuppressants and treatment of neuropathic pain, in which local therapies seem particularly beneficial.

Introduction: Prionopathy is the cause of 62% of the rapidly progressive dementias (RPD) in which a definitive diagnosis is reached. The variability of symptoms and signs exhibited by the patients, as well as its different presentation, sometimes makes an early diagnosis difficult. Methods: Patients with diagnosis of definite or probable prionopathy during the period 1999–2012 at our hospital were retrospectively reviewed. The clinical features and the results of the complementary tests (14-3-3 protein, EEG, MRI, FDG-PET, and genetic analysis) were evaluated in order to identify some factors that may enable an earlier diagnosis to be made. Results: A total of 14 patients are described: 6 with definite sporadic Creutzfeldt-Jakob (sCJD) disease, 3 with probable sCJD, 4 with fatal familial insomnia, and 1 with the new variant. The median age at diagnosis was 54 years old. The mean survival was 9.5 months. Mood disorder was the most common feature, followed by instability and cognitive impairment. 14-3-3 protein content in the cerebrospinal fluid was positive in 7 of 11 patients, and the EEG showed typical signs in 2 of 12 patients. Neuroimaging (FDG-PET, MRI) studies suggested the diagnosis in 13 of the 14 patients included. Conclusions: Most patients presenting with RPD suffer from a prion disease. In our series the most useful complementary tests were MRI and FDG-PET, being positive in 13 of the 14 patients studied. Resumen: Introducción: Las prionopatías representan hasta el 62% de los casos de demencia rápidamente progresiva (DRP) en los que se alcanza un diagnóstico definitivo. La variabilidad de los síntomas y signos iniciales y las diferencias en su evolución dificultan el diagnóstico precoz. Métodos: Estudio retrospectivo en el que se incluye a pacientes con prionopatía probable o definitiva, que acudieron a la consulta de Neurología de nuestro centro durante el periodo 1999–2012. Se describen las características clínicas y los resultados de las exploraciones complementarias (proteína 14-3-3, EEG, RM, PET-FDG y análisis genético), con la finalidad de identificar qué marcadores permiten un diagnóstico precoz. Resultados: Se describe a 14 pacientes: 6 con enfermedad de Creutzfeldt-Jakob esporádica (ECJe) definitiva, 3 con ECJe probable, 4 con insomnio familiar fatal y uno con la nueva variante de la enfermedad de Creutzfeldt-Jakob. La mediana de edad al diagnóstico fue de 54 años y la mediana de supervivencia de 9,5 meses. El trastorno del ánimo fue el síntoma inicial más frecuente, seguido de inestabilidad de la marcha y deterioro cognitivo. La proteína 14-3-3 fue positiva en el líquido cefalorraquídeo en 7 de 11 pacientes y el EEG mostró signos típicos en 2 de 12 pacientes explorados. El estudio de neuroimagen mostró alteraciones en 13 de los 14 pacientes. Conclusiones: Además de la DRP, el trastorno conductual y de la marcha son síntomas iniciales frecuentes en las prionopatías. En nuestra serie, las pruebas complementarias más útiles para apoyar el diagnóstico fueron la RM y la PET-FDG.

Poster Abstract

Objective To expand the differential diagnosis of headache and ophthalmoparesis by describing a case report in which anti-GQ1b was demonstrated to be the cause. Background Anti-GQ1b antibody syndrome refers to a clinical spectrum of conditions that share common mechanisms and overlapping manifestations, including the Miller-Fisher syndrome, pharyngeal-cervical-brachial weakness, and Bickerstaff brainstem encephalitis. Rare atypical cases presenting as acute ophthalmoparesis (AO) without ataxia or areflexia have been described. Headache is a rare condition in these disorders. Methods A 49-year-old woman with no history of headaches began experiencing an acute severe bilateral throbbing headache associated with nausea and photophobia. Five days later, she developed constant binocular horizontal diplopia. Results Bilateral paresis of both sixth nerves was noted. Her ocular fundi, tendon reflexes, and other findings of the physical exam were normal. In addition, both a brain MRI performed with gadolinium and a lumbar puncture yielded normal results. Serum anti-GQ1b IgG was found to be positive. Her symptoms resolved completely following treatment with immunoglobulins (0.4 g/kg/day for 5 days). Conclusions This is the first reported case of AO related to anti-GQ1b antibodies presenting with headache as its initial symptom. The presence of anti-GQ1b antibodies should be determined in patients with headache and AO of unknown origin. Immunoglobulins could hasten the resolution of symptoms in these patients.

Objective: To update the Spanish Society of Neurology's guidelines for subarachnoid haemorrhage diagnosis and treatment. Materials and methods: A review and analysis of the existing literature. Recommendations are given based on the level of evidence for each study reviewed. Results: The most common cause of spontaneous subarachnoid haemorrhage (SAH) is cerebral aneurysm rupture. Its estimated incidence in Spain is 9/100, 000 inhabitants/year with a relative frequency of approximately 5% of all strokes. Hypertension and smoking are the main risk factors. Stroke patients require treatment in a specialised centre. Admission to a stroke unit should be considered for SAH patients whose initial clinical condition is good (Grades I or II on the Hunt and Hess scale). We recommend early exclusion of aneurysms from the circulation. The diagnostic study of choice for SAH is brain CT (computed tomography) without contrast. If the test is negative and SAH is still suspected, a lumbar puncture should then be performed. The diagnostic tests recommended in order to determine the source of the haemorrhage are MRI (magnetic resonance imaging) and angiography. Doppler ultrasonography studies are very useful for diagnosing and monitoring vasospasm. Nimodipine is recommended for preventing delayed cerebral ischaemia. Blood pressure treatment and neurovascular intervention may be considered in treating refractory vasospasm. Conclusions: SAH is a severe and complex disease which must be managed in specialised centres by professionals with ample experience in relevant diagnostic and therapeutic processes. Resumen: Objetivo: Actualización de la guía para el diagnóstico y tratamiento de la hemorragia subaracnoidea de la Sociedad Española de Neurología. Material y métodos: Revisión y análisis de la bibliografía existente. Se establecen recomendaciones en función del nivel de evidencia que ofrecen los estudios revisados. Resultados: La causa más frecuente de hemorragia subaracnoidea espontánea (HSA) es la rotura de un aneurisma cerebral. Su incidencia se sitúa en torno 9 casos por 100.000 habitantes/año y supone un 5% de todos los ictus. La hipertensión arterial y el tabaquismo son sus principales factores de riesgo. Se ha de realizar el tratamiento en centros especializados. Se debe considerar el ingreso en unidades de ictus de aquellos pacientes con HSA y buena situación clínica inicial (grados I y II en la escala de Hunt y Hess). Se recomienda la exclusión precoz de la circulación del aneurisma. El estudio diagnóstico de elección es la tomografía computarizada (TC) craneal sin contraste. Si esta es negativa y persiste la sospecha clínica se aconseja realizar una punción lumbar. Los estudios de elección para identificar la fuente de sangrado son la resonancia magnética (RM) y la angiografía. Los estudios ultrasonográficos son útiles para el diagnóstico y seguimiento del vasoespasmo. Se recomienda el nimodipino para la prevención de la isquemia cerebral diferida. La terapia hipertensiva y el intervencionismo neurovascular pueden plantearse para tratar el vasoespasmo establecido. Conclusiones: La HSA es una enfermedad grave y compleja que debe ser atendida en centros especializados, con suficiente experiencia para abordar el proceso diagnóstico y terapéutico.

Resumen: Fundamento y objetivo: Actualizar las guías terapéuticas del Comité ad hoc del Grupo de Estudio de Enfermedades Cerebrovasculares de la SEN en el tratamiento preventivo de ictus isquémico (II) y ataque isquémico transitorio (AIT). Métodos: Revisión de evidencias disponibles sobre la prevención del ictus isquémico y AIT en función del subtipo etiológico. Los niveles de evidencia y grados de recomendación se han basado en la clasificación del Centro de Medicina Basada en la Evidencia. Resultados: En el II de origen aterotrombótico reducen el riesgo de recurrencias el tratamiento antiagregante y los procedimientos revascularizadores en casos seleccionados de estenosis carotidea ipsilateral (70-99%). La prevención de II de origen cardioembólico (fibrilación auricular, valvulopatías, prótesis valvulares y en infarto de miocardio con trombo mural) se basa en el uso de anticoagulantes orales. En el II de origen inhabitual, las terapias preventivas dependerán de la etiología; en la trombosis venosa cerebral la anticoagulación oral es eficaz. Conclusiones: Se concluye con recomendaciones de práctica clínica en prevención de ictus isquémico y AIT adaptadas al subtipo etiológico de II que ha presentado el paciente. Abstract: Background and Objective: To update the ad hoc Committee of the Cerebrovascular Diseases Study Group of The Spanish Neurological Society guidelines on prevention of ischaemic stroke (IS) and Transient Ischaemic Attack (TIA). Methods: We reviewed the available evidence on ischaemic stroke and TIA prevention according to aetiological subtype. Levels of evidence and recommendation levels are based on the classification of the Centre for Evidence-Based Medicine. Results: In atherothrombotic IS, antiplatelet therapy and revascularization procedures in selected cases of ipsilateral carotid stenosis (70%-90%) reduce the risk of recurrences. In cardioembolic IS (atrial fibrillation, valvular diseases, prosthetic valves and myocardial infarction with mural thrombus) prevention is based on the use of oral anticoagulants. Preventive therapies for uncommon causes of IS will depend on the aetiology. In the case of cerebral venous thrombosis oral anticoagulation is effective. Conclusions: We conclude with recommendations for clinical practice in prevention of IS according to the aetiological subtype presented by the patient.

Introduction: Update of Acute Ischaemic Stroke Treatment Guidelines of the Spanish Neurological Society based on a critical review of the literature. Recommendations are made based on levels of evidence from published data and studies. Development: Organised systems of care should be implemented to ensure access to the optimal management of all acute stroke patients in stroke units. Standard of care should include treatment of blood pressure (should only be treated if values are over 185/105 mmHg), treatment of hyperglycaemia over 155 mg/dl, and treatment of body temperature with antipyretic drugs if it rises above 37.5 °C. Neurological and systemic complications must be prevented and promptly treated. Decompressive hemicraniectomy should be considered in cases of malignant cerebral oedema. Intravenous thrombolysis with rtPA should be administered within 4.5 hours from symptom onset, except when there are contraindications. Intra-arterial pharmacological thrombolysis can be considered within 6 hours, and mechanical thrombectomy within 8 hours from onset, for anterior circulation strokes, while a wider window of opportunity up to 12–24 hours is feasible for posterior strokes. There is not enough evidence to recommend routine use of the so-called neuroprotective drugs. Anticoagulation should be administered to patients with cerebral vein thrombosis. Rehabilitation should be started as early as possible. Conclusion: Treatment of acute ischaemic stroke includes management of patients in stroke units. Systemic thrombolysis should be considered within 4.5 hours from symptom onset. Intra-arterial approaches with a wider window of opportunity can be an option in certain cases. Protective and restorative therapies are being investigated. Resumen: Introducción: Actualización de la guía para el tratamiento del infarto cerebral agudo de la Sociedad Española de Neurología basada en la revisión y análisis de la bibliografía existente sobre el tema. Se establecen recomendaciones en base al nivel de evidencia que ofrecen los estudios revisados. Desarrollo: Los sistemas de asistencia urgente extrahospitalaria se organizarán para asegurar la atención especializada de los pacientes y el ingreso en unidades de ictus (UI). Deben aplicarse cuidados generales para mantener la homeostasis (tratar la tensión arterial sistólica > 185 mmHg o diastólica > 105 mmHg, evitar hiperglucemia > 155 mg/dl y controlar la temperatura, tratando con antitérmicos cifras > 37,5 °C), y prevenir y tratar las complicaciones. La craniectomía descompresiva debe ser considerada en casos seleccionados de oedema cerebral maligno. La trombólisis intravenosa con rtPA se administrará en las primeras 4,5 horas en pacientes sin contraindicación. La trombólisis intraarterial farmacológica puede indicarse en las primeras 6 horas de evolución y la trombectomía mecánica hasta las 8 horas. En el territorio posterior la ventana puede ampliarse hasta 12–24 horas. No hay evidencias para recomendar el uso rutinario de los fármacos denominados neuroprotectores. Se recomienda la anticoagulación en pacientes con trombosis de senos venosos. Se aconseja el inicio precoz de rehabilitación. Conclusiones: El tratamiento del infarto cerebral se basa en la atención especializada en UI, la aplicación urgente de cuidados generales y el tratamiento trombolítico intravenoso en las primeras 4,5 horas. La recanalización intraarterial farmacológica o mecánica pueden ser útiles en casos seleccionados. Terapias de protección y reparación cerebral están en desarrollo.
