Diagnosis and treatment of disorders of intracranial pressure: consensus statement of the Spanish Society of Neurology's Headache Study Group.

Primary intracranial pressure disorders include idiopathic intracranial hypertension and spontaneous intracranial hypotension. Remarkable advances have been made in the diagnosis and treatment of these 2entities in recent years. Therefore, the Spanish Society of Neurology's Headache Study Group (GECSEN) deemed it necessary to prepare this consensus statement, including diagnostic and therapeutic algorithms to facilitate and improve the management of these disorders in clinical practice. This document was created by a committee of experts belonging to GECSEN, and is based on a systematic review of the literature, incorporating the experience of the participants, and establishes practical recommendations with levels of evidence and grades of recommendation.

[New therapeutic era for migraine attacks with recently approved monoclonal antibodies, ditans and gepants]. / Nueva era terapéutica para el ataque de migraña con los recientemente aprobados anticuerpos monoclonales, ditanes y gepantes.

Treatment of migraine attacks is advised in all patients, using non-steroidal anti-inflammatory drugs when the pain is mild and triptans when the pain intensity is moderate-severe. However, the effectiveness of these drugs is moderate, a high percentage of patients have side effects, and triptans are contraindicated in people with a history of stroke, ischaemic heart disease or poorly controlled hypertension. Hence, there is an urgent need for new therapeutic alternatives. In recent years, new drugs for migraine attacks have become available, most notably ditans (lasmiditan) and gepants (ubrogepant and rimegepant). Furthermore, eptinezumab, which has been approved for the preventive treatment of migraine in adults, has also been used for migraine attacks. This manuscript reviews the efficacy and safety results of the new drugs for migraines that will soon be on the market.

TITLE: Nueva era terapéutica para el ataque de migraña con los recientemente aprobados anticuerpos monoclonales, ditanes y gepantes.El tratamiento de los ataques de migraña se aconseja en todos los pacientes, utilizando antiinflamatorios no esteroideos cuando el dolor es leve y triptanes cuando la intensidad del dolor es moderada-grave. Sin embargo, la efectividad de estos fármacos es modesta, un porcentaje elevado de pacientes presenta efectos secundarios y los triptanes están contraindicados en las personas con antecedentes de ictus, cardiopatía isquémica o hipertensión mal controlada. Por tanto, es imprescindible disponer de nuevas alternativas terapéuticas. En los últimos años han ido apareciendo nuevos fármacos para los ataques de migraña, entre los que destacan los ditanes (lasmiditán) y los gepantes (ubrogepant y rimegepant). Por otro lado, el eptinezumab, que ha sido aprobado para el tratamiento preventivo de la migraña en adultos, se ha utilizado también para los ataques de migraña. En este manuscrito se revisan los resultados de eficacia y seguridad de los nuevos fármacos para los ataques de migraña que se comercializarán próximamente.

Management of cerebral venous thrombosis in Spain: MOTIVATE descriptive study.

INTRODUCTION: Cerebral venous thrombosis (CVT) is an uncommon cause of stroke that mainly affects young adults. Early, accurate diagnosis can reduce the rate and severity of complications. OBJECTIVE: The aim of this study was to analyse the clinical characteristics, management, and treatment of CVT in different centres in Spain. METHODS: We conducted a multicentre, retrospective, descriptive study of patients hospitalised due to CVT between 2008 and 2017 at 10 Spanish centres. RESULTS: We included 256 patients, with a mean age (SD) of 49.8 (18.7) years; 51% of patients were women. The most frequent symptoms were headache (73%), focal deficits (50%), epileptic seizures (33%), and encephalopathy (21%). The most frequent localisations were the superior sagittal sinus (12.5%), the transverse sinus (10.9%), and 2 or more sinuses or veins (66.4%). Thrombophilia was the most frequent known aetiology (24%), and was most commonly associated with the prothrombin G20210A mutation (19%). Forty-six percent of patients were treated with antithrombotics for 3 to 6 months, 21% for one year, and 22.6% required indefinite anticoagulation. Endovascular therapy was performed in 5% of cases, and 33% required neurosurgery. Regarding outcomes, 75% of patients were independent at 3 months (modified Rankin Scale [mRS] score ≤ 2), with papilloedema (P =  .03), focal deficits (P = .001), and encephalopathy (P < .001) showing a statistically significant association with poor prognosis (mRS > 3). The in-hospital mortality rate was 4.3%, with a 3-month mortality rate of 6.3%. CONCLUSION: The diverse risk factors and variable presentation of CVT represent a challenge in the diagnosis and treatment of this condition. To improve prognosis and reduce mortality, it is essential to establish management protocols for this entity.

Telemedicine in the management of patients with headache: current situation and recommendations of the Spanish Society of Neurology's Headache Study Group.

INTRODUCTION: The COVID-19 pandemic has caused an unexpected boost to telemedicine. We analyse the impact of the pandemic on telemedicine applied in Spanish headache consultations, review the literature, and issue recommendations for the implementation of telemedicine in consultations. METHOD: The study comprised 3 phases: 1) review of the MEDLINE database since 1958 (first reported experience with telemedicine); 2) Google Forms survey sent to all members of the Spanish Society of Neurology's Headache Study Group (GECSEN); and 3) online consensus of GECSEN experts to issue recommendations for the implementation of telemedicine in Spain. RESULTS: COVID-19 has increased waiting times for face-to-face consultations, increasing the use of all telemedicine modalities: landline telephone (from 75% before April 2020 to 97% after), mobile telephone (from 9% to 27%), e-mail (from 30% to 36%), and video consultation (from 3% to 21%). Neurologists are aware of the need to expand the availability of video consultations, which are clearly growing, and other e-health and m-health tools. CONCLUSIONS: The GECSEN recommends and encourages all neurologists who assist patients with headaches to implement telemedicine resources, with the optimal objective of offering video consultation to patients under 60-65 years of age and telephone calls to older patients, although each case must be considered on an individual basis. Prior approval and advice must be sought from legal and IT services and the centre's management. Most patients with stable headache and/or neuralgia are eligible for telemedicine follow-up, after a first consultation that must always be held in person.

[Prognosis of patients assisted in the emergency unit by the 'TIA protocol' in a third-level hospital at 90 days]. / Pronóstico de pacientes atendidos en urgencias mediante 'protocolo AIT' en un hospital de tercer nivel a los 90 días.

INTRODUCTION: Care models developed for the rapid management of patients with transient ischaemic attack (TIA) are safe, effective and reduce recurrence rates. The aim is to determine the prevalence of cardiovascular events at 90 days. PATIENTS AND METHODS: An observational, analytical, cross-sectional study was conducted. Adult male and female patients seen in the emergency department using the 'TIA protocol' between January 2016 and December 2019 were analysed. Data were collected on clinical variables, complementary tests, treatment and cardiovascular events (stroke/TIA, acute coronary syndrome or death due to cardiovascular causes) at 90 days. The study was approved by the Research Ethics Committee of Aragon. RESULTS: The TIA protocol was performed on 163 out of 591 patients diagnosed with TIA in the emergency department. Brain CT and neurosonology scans were performed in 100% and a 24-hour Holter-electrocardiogram was carried out in 52.1%; atrial fibrillation (AF) was detected in 3.6% of them. An MRI brain scan was performed in 78.4% and acute ischaemic injury was seen in diffusion sequences (DWI+) in 13.5%. The prevalence of cardiovascular events at 90 days was 4.9% (8): stroke, 3.1% (five TIAs); acute coronary syndrome, 0.6% (one); and death from cardiovascular causes, 1.2% (two). Major adverse cardiovascular events were significantly associated with a history of ischaemic heart disease (p = 0.014). Cardiovascular death was associated with a history of AF (p = 0.008), anticoagulants at discharge (p = 0.007) and no antiplatelet therapy at discharge (p = 0.012), and there was a tendency towards an association with a history of type 2 diabetes mellitus (p = 0.05). CONCLUSIONS: Rapid TIA protocols allow early care and avoid hospital admissions, without increasing the incidence of cardiovascular events or recurrence of stroke or TIA at 90 days.

TITLE: Pronóstico de pacientes atendidos en urgencias mediante 'protocolo AIT' en un hospital de tercer nivel a los 90 días.Introducción. Los modelos asistenciales desarrollados para el manejo rápido de pacientes con accidente isquémico transitorio (AIT) son seguros, eficaces y disminuyen las tasas de recurrencia. El objetivo es conocer la prevalencia de eventos cardiovasculares a 90 días. Pacientes y métodos. Estudio observacional, analítico y transversal. Se analiza a pacientes adultos de ambos sexos atendidos en urgencias mediante el 'protocolo AIT' entre enero de 2016 y diciembre de 2019. Se recogen variables clínicas, pruebas complementarias, tratamiento y eventos cardiovasculares (ictus/AIT, síndrome coronario agudo o muerte por causa cardiovascular) a los 90 días. El estudio fue aprobado por el Comité Ético de Investigación de Aragón. Resultados. Se realizó el protocolo AIT a 163 de 591 pacientes diagnosticados de AIT en urgencias. Se realizó una tomografía computarizada cerebral y una neurosonología al 100%, y un Holter-electrocardiograma de 24 horas al 52,1%, y se detectó fibrilación auricular (FA) en el 3,6%. Se hizo una resonancia magnética cerebral al 78,4%, y se demostró lesión isquémica aguda en secuencias de difusión (DWI+) en un 13,5%. La prevalencia de eventos cardiovasculares a los 90 días fue del 4,9% (8): ictus, el 3,1% (cinco AIT); síndrome coronario agudo, el 0,6% (uno), y muerte por causa cardiovascular, el 1,2% (dos). Los eventos adversos cardiovasculares mayores se asociaron de forma significativa al antecedente de cardiopatía isquémica (p = 0,014). La muerte por causa cardiovascular se asoció al antecedente de FA (p = 0,008), anticoagulación al alta (p = 0,007) y no antiagregación al alta (p = 0,012), y hubo una tendencia a la asociación con antecedente de diabetes mellitus de tipo 2 (p = 0,05). Conclusiones. Los protocolos AIT de actuación rápida permiten una atención precoz y evitan ingresos hospitalarios, sin implicar un incremento en la incidencia de eventos cardiovasculares o recurrencia de ictus o AIT a los 90 días.

Headache as a reason for consultation: the primary care perspective.

INTRODUCTION: Headache is a frequent reason for consultation with primary care (PC) physicians. However, the condition is underdiagnosed and undertreated. One reason for this may be the lack of specific training on headache in PC. METHODS: We conducted a descriptive cross-sectional study of data gathered with a self-administered survey that was completed by PC physicians from our health district. We collected sociodemographic data and information on previous training in neurology and headache, and training needs. RESULTS: The survey was completed by 104 PC physicians, 53% of whom were women; mean age was 49 years. Most respondents worked in urban settings (42.3%) and had been trained via residency (77.9%). Although 65.4% spent more time with patients with headache than with other patients, only 32.7% used the International Classification of Headache Disorders. In our sample, 68.3% of respondents reported a high or very high interest in headache, and 75.9% wished to receive further training on the condition; theoretical and practical courses and update lectures were regarded as the most useful tools. In clinical practice, 90% used triptans and 78% used preventive treatments. The most frequently used drug was amitriptyline; only 22.1% choose topiramate. CONCLUSIONS: PC physicians are in frequent contact with patients with headache and show interest in receiving training on this condition. This could be helpful in designing training programmes aimed at improving quality of care in this area.

Safety of anti-CGRP monoclonal antibodies in patients with migraine during the COVID-19 pandemic: Present and future implications.

BACKGROUND AND OBJECTIVE: CGRP, a neuropeptide involved in migraine pathophysiology, is also known to play a role in the respiratory system and in immunological conditions such as sepsis. We analyzed the impact of the use of CGRP antagonists in patients with migraine during the COVID-19 pandemic, caused by the SARS-CoV-2 coronavirus. METHODS: This is a multicentre cross-sectional study. From May to November 2020, through a national survey distributed by the Spanish Society of Neurology, we collected data about the presence of COVID-19 symptoms including headache and their characteristics and severity in patients with migraine treated with anti-CGRP monoclonal antibodies (mAb), and compared them with patients with migraine not receiving this treatment. We also conducted a subanalysis of patients with COVID-19 symptoms. RESULTS: We recruited 300 patients with migraine: 51.7% (155/300) were taking anti-CGRP mAbs; 87.3% were women (262/300). Mean age (standard deviation) was 47.1 years (11.6). Forty-one patients (13.7%) met diagnostic criteria for COVID-19, with no statistically significant difference between patients with and without anti-CGRP mAb treatment (16.1% vs 11.0%, respectively; P=.320). Of the patients with COVID-19, 48.8% (20/41) visited the emergency department and 12.2% (5/41) were hospitalised. Likewise, no clinical differences were found between the groups of patients with and without anti-CGRP mAb treatment. CONCLUSION: Anti-CGRP mAbs may be safe in clinical practice, presenting no association with increased risk of COVID-19.

The in-hospital mortality rate was 4.3%, with a 3-month mortality rate of 6.3%. CONCLUSION: The diverse risk factors and variable presentation of CVT represent a challenge in the diagnosis and treatment of this condition. To improve prognosis and reduce mortality, it is essential to establish management protocols for this entity.

[Degree of compliance with treatment at three months in migraine patients]. / Grado de cumplimiento terapéutico a los tres meses en pacientes con migraña.

INTRODUCTION: Adherence to oral preventive treatment (OPT) in migraine is often compromised. The aim was to determine the degree of adherence to OPT in migraine patients at three months. PATIENTS AND METHODS: We conducted a multicentre observational study of patients diagnosed with episodic or chronic migraine (criteria of the International Headache Classification, third edition) in whom OPT was initiated. Demographic data (age, gender, educational level, marital status) and disease data (number of attacks, Headache Impact Test-6 and Migraine Disability Assessment Scale scores) were collected. At three months, the Morisky-Green scale was administered, which differentiates levels of adherence: excellent (0), moderate (1-2) and low (3-4). RESULTS: Altogether 100 patients participated in the study: 87% women aged 42 ± 13 years, 14% with chronic migraine; 53.2% of them were beginning their first OPT. Beta-blockers were initiated in 23.2%, tricyclic antidepressants in 35.4%, flunarizine in 21.2%, neuromodulators in 19.2% and antihypertensives in 1%. Severe disability was observed in 56%, and the impact was very severe in 79.5%. Adhesion at three months was excellent in 41.8%, moderate in 28.6% and low in 29.6%. The most frequent reason for discontinuing was the occurrence of adverse effects (44%). A significant relationship was found between excellent adherence and being single (p = 0.046), and between low adherence and adverse effects (p = 0.009). No significant differences were found between the OPT used and the degree of adherence or the other variables studied. CONCLUSIONS: Although our results are better than those published in the literature, we consider that therapeutic adherence in our setting is low and educating our patients in this regard is a priority.

TITLE: Grado de cumplimiento terapéutico a los tres meses en pacientes con migraña.Introducción. La adhesión al tratamiento preventivo oral (TPO) en la migraña se ve frecuentemente comprometida. El objetivo fue conocer el grado de adhesión al TPO en pacientes con migraña a los tres meses. Pacientes y métodos. Estudio multicéntrico observacional de pacientes diagnosticados de migraña episódica o crónica (criterios de la Clasificación Internacional de Cefaleas, tercera edición) en los que se iniciaba TPO. Se recogieron datos demográficos (edad, género, nivel estudios, estado civil) y de enfermedad (número de ataques, puntuación en las escalas Headache Impact Test-6 y Migraine Disability Assessment Scale). A los tres meses se pasó la escala de Morisky Green, que diferencia niveles de adhesión: excelente (0), moderada (1-2) y baja (3-4). Resultados. Participaron 100 pacientes, un 87% mujeres de 42 ± 13 años, el 14% con migraña crónica. El 53,2% comenzaba su primer TPO. Se iniciaron betabloqueantes en el 23,2%, antidepresivos tricíclicos en el 35,4%, flunaricina en el 21,2%, neuromoduladores en el 19,2% y antihipertensivos en el 1%. El 56% presentaba discapacidad grave y el 79,5%, impacto muy grave. La adhesión a los tres meses fue excelente en el 41,8%, moderada en el 28,6% y baja en el 29,6%. El motivo más frecuente de discontinuación fueron los efectos adversos (44%). Se encontró una relación significativa entre adhesión excelente y estado civil soltero (p = 0,046), y entre adhesión baja y efectos adversos (p = 0,009). No se encontraron diferencias significativas entre los TPO empleados y el grado de adhesión ni con el resto de variables estudiadas. Conclusiones. Aunque nuestros resultados son mejores que los publicados en la bibliografía, consideramos que la adhesión terapéutica en nuestro medio es baja y es prioritario educar a nuestros pacientes en este sentido.

[Abiotrophia defectiva, an infrequent cause of cardioembolic stroke].

Abiotrophia defectiva is a rare cause of endocarditis with a high embolization rate compared to other streptococcal endocarditis. Neurological complications may occur in 20-40% of cases, and include intracranial aneurysms and sub-arachnoid hemorrhage. Its isolation in the central nervous system (CNS) is extremely rare and is associated with previous neurosurgical procedures. We present the case of a 51-year-old patient who suffered an ischemic stroke as a complication of A. defectiva endocarditis, and the cases of CNS infections caused by this microorganism are reviewed. The relevance of the case lies in its singular character, due to the absence of previous valve disease in the patient without a recent history of invasive procedures or surgical interventions.

Impact of the COVID-19 pandemic on headache management in Spain: an analysis of the current situation and future perspectives. / Impacto de la pandemia COVID-19 en la atención al paciente con cefalea en España: análisis de situación con una mirada al futuro.

INTRODUCTION: The COVID-19 pandemic has had a great impact on healthcare systems. Spain, where headache is the main reason for outpatient neurology consultation, is one of the countries with the most reported cases of the disease. OBJECTIVE: This study aimed to analyse the impact of the COVID-19 pandemic on headache units in Spain and to evaluate how neurologists see the future of these units. METHODS: We conducted a cross-sectional online survey of headache units during the sixth week of the state of alarm declared in Spain in response to the pandemic. RESULTS: The response rate was 74%, with the participation of centres with different characteristics and from all Autonomous Communities of Spain. Limitations in face-to-face activity were reported by 95.8% of centres, with preferential face-to-face consultation being maintained in 60.4%, and urgent procedures in 45.8%. In 91.7% of centres, the cancelled face-to-face activity was replaced by telephone consultation. 95.8% of respondents stated that they would use personal protection equipment in the future, and 86% intended to increase the use of telemedicine. The majority foresaw an increase in waiting lists (93.8% for initial consultations, 89.6% for follow-up, and 89.4% for procedures) and a worse clinical situation for patients, but only 15% believed that their healthcare structures would be negatively affected in the future. CONCLUSIONS: As a consequence of the pandemic, headache care and research activity has reduced considerably. This demonstrates the need for an increase in the availability of telemedicine in our centres in the near future.

Usefulness of electroencephalography for the management of epilepsy in emergency departments. / Utilidad del electroencefalograma en el manejo de la epilepsia en el Servicio de Urgencias.

INTRODUCTION: Electroencephalography (EEG) is an essential diagnostic tool in epilepsy. Its use in emergency departments (ED) is usually restricted to the diagnosis and management of non-convulsive status epilepticus (NCSE). However, EDs may also benefit from EEG in the context of other situations in epilepsy. METHODS: We conducted a retrospective observational study using the clinical histories of patients treated at our hospital's ED for epileptic seizures and suspicion of NCSE and undergoing EEG studies in 2015 and 2016. We collected a series of demographic and clinical variables. RESULTS: Our sample included 87 patients (mean age of 44 years). Epileptic seizures constituted the most common reason for consultation: 59.8% due to the first episode of epileptic seizures (FES), 27.6% due to recurrence, and 12.6% due to suspected NCSE. Interictal epileptiform discharges (IED) were observed in 38.4% of patients reporting FES and in 33.3% of those with a known diagnosis of epilepsy. NCSE was confirmed by EEG in 36.4% of all cases of suspected NCSE. Presence of IED led to administration of or changes in long-term treatment in 59.8% of the patients. CONCLUSIONS: EEG is a useful tool for seizure management in EDs, not only for severe, sudden-onset clinical situations such as NCSE but also for diagnosis in cases of non-affiliated epilepsy and in patients experiencing the first episode of epilepsy.

[OnabotulinumtoxinA in the treatment of atypical odontalgia: description of a clinical case]. / OnabotulinumtoxinA en el tratamiento de la odontalgia atípica: descripción de un caso clínico.

Atypical odontalgia (AO) is defined as a continuous dental pain in the area of one or several teeth, sometimes preceded by dental procedures in the absence of signs of dental pathology after complete examination. It is thought to have a neuropathic origin in which the response to local and systemic treatment is insufficient. We present the case of a 50-year-old patient with AO after dental extraction, who presented a significant reduction in pain after local treatment with OnabotulinumtoxinA (OnabotA) in the symptomatic area. The response to the administration of OnabotA in this patient is in line with what had previously been observed in small series of cases, so it could be a therapeutic alternative in this type of pain that is difficult to control.
