BACKGROUND AND PURPOSE: The European Academy of Neurology (EAN) has adhered to the global plan for reducing the burden of neurological disorders and promoting brain health launched by the World Health Organisation (WHO), the WHO Intersectoral Global Action Plan on Epilepsy and Other Neurological Disorders. This study reports the results of an EAN survey among national neurological societies (NNSs) on their awareness of brain health policies. METHODS: The EAN survey on the current state of national brain health policies was conducted among the 47 presidents of the NNSs affiliated with the EAN, with the aim of developing the best strategy for close collaboration among stakeholders. RESULTS: From June 2023 to February 2024, 36/47 responses (77%) were collected. Among respondents, 67% were in contact with their Ministry of Health and 78% were aware of and in contact with one or more national neurological patient organisation, while 17% had no contacts with any association. Ninety-two percent declared a high to medium degree of awareness of the need to support brain health and of brain health plans and strategies in their country. CONCLUSIONS: Our findings suggest good awareness of the importance of brain health and of the strategies implemented at the national level among the EAN-affiliated NNSs and representatives. Efforts towards improvement may be directed towards cooperation between NNSs and political institutions, as well as patient organisations, to optimise brain and global public health and neurological care in each country.

BACKGROUND: Patients with acute intracerebral hemorrhage who are receiving factor Xa inhibitors have a risk of hematoma expansion. The effect of andexanet alfa, an agent that reverses the effects of factor Xa inhibitors, on hematoma volume expansion has not been well studied. METHODS: We randomly assigned, in a 1:1 ratio, patients who had taken factor Xa inhibitors within 15 hours before having an acute intracerebral hemorrhage to receive andexanet or usual care. The primary end point was hemostatic efficacy, defined by expansion of the hematoma volume by 35% or less at 12 hours after baseline, an increase in the score on the National Institutes of Health Stroke Scale of less than 7 points (scores range from 0 to 42, with higher scores indicating worse neurologic deficit) at 12 hours, and no receipt of rescue therapy between 3 hours and 12 hours. Safety end points were thrombotic events and death. RESULTS: A total of 263 patients were assigned to receive andexanet, and 267 to receive usual care. Efficacy was assessed in an interim analysis that included 452 patients, and safety was analyzed in all 530 enrolled patients. Atrial fibrillation was the most common indication for factor Xa inhibitors. Of the patients receiving usual care, 85.5% received prothrombin complex concentrate. Hemostatic efficacy was achieved in 150 of 224 patients (67.0%) receiving andexanet and in 121 of 228 (53.1%) receiving usual care (adjusted difference, 13.4 percentage points; 95% confidence interval [CI], 4.6 to 22.2; P = 0.003). The median reduction from baseline to the 1-to-2-hour nadir in anti-factor Xa activity was 94.5% with andexanet and 26.9% with usual care (P<0.001). Thrombotic events occurred in 27 of 263 patients (10.3%) receiving andexanet and in 15 of 267 (5.6%) receiving usual care (difference, 4.6 percentage points; 95% CI, 0.1 to 9.2; P = 0.048); ischemic stroke occurred in 17 patients (6.5%) and 4 patients (1.5%), respectively. There were no appreciable differences between the groups in the score on the modified Rankin scale or in death within 30 days. CONCLUSIONS: Among patients with intracerebral hemorrhage who were receiving factor Xa inhibitors, andexanet resulted in better control of hematoma expansion than usual care but was associated with thrombotic events, including ischemic stroke.

BACKGROUND: Covert brain infarcts are associated with important neurological morbidity. Their incidence in patients with embolic stroke of undetermined source (ESUS) is unknown. AIMS: To assess the incidence of covert brain infarcts and cerebral microbleeds using MRI in a prospective substudy of the NAVIGATE ESUS randomized trial and to evaluate the effects of antithrombotic therapies. METHODS: At 87 sites in 15 countries, substudy participants were randomly assigned to receive rivaroxaban 15 mg daily or aspirin 100 mg daily and underwent brain MRI near randomization and after study termination. The primary outcome was incident brain infarct (clinical ischemic stroke or covert brain infarct). Brain infarcts and microbleeds were ascertained centrally by readers unaware of treatment. Treatment effects were estimated using logistic regression. RESULTS: Among the 718 substudy participants with interpretable, paired MRIs, the mean age was 67 years and 61% were men with a median of 52 days between the qualifying ischemic stroke and randomization and a median of seven days between randomization and baseline MRI. During the median (IQR) 11 (12) month interval between scans, clinical ischemic strokes occurred in 27 (4%) participants, while 60 (9%) of the remaining participants had an incident covert brain infarct detected by MRI. Assignment to rivaroxaban was not associated with reduction in the incidence of brain infarct (OR 0.77, 95% CI 0.49, 1.2) or of covert brain infarct among those without clinical stroke (OR 0.85, 95% CI 0.50, 1.4). New microbleeds were observed in 7% and did not differ among those assigned rivaroxaban vs. aspirin (HR 0.95, 95% CI 0.52-1.7). CONCLUSIONS: Incident covert brain infarcts occurred in twice as many ESUS patients as a clinical ischemic stroke. Treatment with rivaroxaban compared with aspirin did not significantly reduce the incidence of covert brain infarcts or increase the incidence of microbleeds, but the confidence intervals for treatment effects were wide.Registration: https://www.clinicaltrials.gov.

BACKGROUND: Non-stenotic intracranial and systemic atherosclerosis are associated with ischemic stroke. We report frequency and response to anticoagulant vs. antiplatelet prophylaxis of patients with embolic stroke of undetermined source (ESUS) who have non-stenotic intracranial atherosclerosis and/or systemic atherosclerosis. METHODS: Exploratory analysis of the international NAVIGATE ESUS randomized trial comparing rivaroxaban 15mg daily with aspirin 100mg daily in 7213 patients with recent ESUS. Among participants with results of intracranial arterial imaging with either computed tomographic angiography (CTA) or magnetic resonance angiography (MRA), the frequency and predictors of non-stenotic intracranial and systemic atherosclerosis and responses to antithrombotic therapy were assessed. RESULTS: Among 4723 participants with available intracranial CTA or MRA results (65% of the trial cohort), the prevalence of intracranial atherosclerosis was 16% (n=739). Patient features independently associated with intracranial atherosclerosis included East Asian region (odds ratio 2.7, 95%CI 2.2,3.3) and cervical carotid plaque (odds ratio 2.3, 95%CI 1.9,2.7), among others. The rate of recurrent ischemic stroke averaged 4.8%/year among those with intracranial atherosclerosis vs. 5.0.%/year for those without (HR 0.95, 95%CI 0.65, 1.4). Among those with intracranial atherosclerosis, the recurrent ischemic stroke rate was higher if assigned to rivaroxaban (5.8%/year) vs. aspirin (3.7%/year), but the difference was not statistically significant (HR 1.6, 95%CI 0.78, 3.3). There was trend for the effect of antithrombotic treatments to be different according to the presence or absence of intracranial atherosclerosis (pinteraction=0.09). Among participants with evidence of systemic atherosclerosis by either history or imaging (n=3820), recurrent ischemic stroke rates were similar among those assigned to rivaroxaban (5.5%/year) vs. aspirin (4.9%/year)(HR 1.1, 95%CI 0.84, 1.5). CONCLUSIONS: East Asia region was the strongest factor associated with intracranial atherosclerosis. There were no statistically significant differences between rivaroxaban and aspirin prophylaxis for recurrent ischemic stroke in patients with non-stenotic intracranial atherosclerosis and/or systemic atherosclerosis.

Introduction: Despite the availability of prevention and therapies of stroke, their implementation in clinical practice, even of low-cost ones, remains poor. In 2015, the European Stroke Organisation (ESO) initiated the ESO Enhancing and Accelerating Stroke Treatment (EAST) program, which aims to improve stroke care quality, primarily in Eastern Europe. Here, we describe its methods and milestones. Patients and methods: The ESO EAST program is using an implementation strategy based on a 'detecting-understanding-reducing disparities' conceptual framework: stroke care quality is first measured (after developing a platform for data collection), gaps are identified in the current service delivery, and ultimately feedback is provided to participating hospitals, followed by the application of interventions to reduce disparities. The ESO EAST program is carried out by establishing a stroke quality registry, stroke management infrastructure, and creating education and training opportunities for healthcare professionals. Results: Program management and leadership infrastructure has been established in 19 countries (Country Representatives in 22 countries, National Steering Committee in 19 countries). A software platform for data collection and analysis: Registry of Stroke Care Quality was developed, and launched in 2016, and has been used to collect data from over 90,000 patients from >750 hospitals and 56 countries between September 2016 and May 2019. Training in thrombolysis, nursing and research skills has been initiated. Discussion: ESO EAST is the first pan-Eastern European (and beyond) multifaceted quality improvement intervention putting evidence-informed policies into practice. Continuous monitoring of stroke care quality allows hospital-to-hospital and country-to-country benchmarking and identification of the gaps and needs in health care.

BACKGROUND: Embolic strokes of undetermined source represent 20% of ischemic strokes and are associated with a high rate of recurrence. Anticoagulant treatment with rivaroxaban, an oral factor Xa inhibitor, may result in a lower risk of recurrent stroke than aspirin. METHODS: We compared the efficacy and safety of rivaroxaban (at a daily dose of 15 mg) with aspirin (at a daily dose of 100 mg) for the prevention of recurrent stroke in patients with recent ischemic stroke that was presumed to be from cerebral embolism but without arterial stenosis, lacune, or an identified cardioembolic source. The primary efficacy outcome was the first recurrence of ischemic or hemorrhagic stroke or systemic embolism in a time-to-event analysis; the primary safety outcome was the rate of major bleeding. RESULTS: A total of 7213 participants were enrolled at 459 sites; 3609 patients were randomly assigned to receive rivaroxaban and 3604 to receive aspirin. Patients had been followed for a median of 11 months when the trial was terminated early because of a lack of benefit with regard to stroke risk and because of bleeding associated with rivaroxaban. The primary efficacy outcome occurred in 172 patients in the rivaroxaban group (annualized rate, 5.1%) and in 160 in the aspirin group (annualized rate, 4.8%) (hazard ratio, 1.07; 95% confidence interval [CI], 0.87 to 1.33; P=0.52). Recurrent ischemic stroke occurred in 158 patients in the rivaroxaban group (annualized rate, 4.7%) and in 156 in the aspirin group (annualized rate, 4.7%). Major bleeding occurred in 62 patients in the rivaroxaban group (annualized rate, 1.8%) and in 23 in the aspirin group (annualized rate, 0.7%) (hazard ratio, 2.72; 95% CI, 1.68 to 4.39; P<0.001). CONCLUSIONS: Rivaroxaban was not superior to aspirin with regard to the prevention of recurrent stroke after an initial embolic stroke of undetermined source and was associated with a higher risk of bleeding.

BACKGROUND: The New Approach Rivaroxaban Inhibition of Factor Xa in a Global Trial vs. ASA to Prevent Embolism in Embolic Stroke of Undetermined Source (NAVIGATE-ESUS) trial is a randomized phase-III trial comparing rivaroxaban versus aspirin in patients with recent ESUS. AIMS: We aimed to describe the baseline characteristics of this large ESUS cohort to explore relationships among key subgroups. METHODS: We enrolled 7213 patients at 459 sites in 31 countries. Prespecified subgroups for primary safety and efficacy analyses included age, sex, race, global region, stroke or transient ischemic attack prior to qualifying event, time to randomization, hypertension, and diabetes mellitus. RESULTS: Mean age was 66.9 ± 9.8 years; 24% were under 60 years. Older patients had more hypertension, coronary disease, and cancer. Strokes in older subjects were more frequently cortical and accompanied by radiographic evidence of prior infarction. Women comprised 38% of participants and were older than men. Patients from East Asia were oldest whereas those from Latin America were youngest. Patients in the Americas more frequently were on aspirin prior to the qualifying stroke. Acute cortical infarction was more common in the United States, Canada, and Western Europe, whereas prior radiographic infarctions were most common in East Asia. Approximately forty-five percent of subjects were enrolled within 30 days of the qualifying stroke, with earliest enrollments in Asia and Eastern Europe. CONCLUSIONS: NAVIGATE-ESUS is the largest randomized trial comparing antithrombotic strategies for secondary stroke prevention in patients with ESUS. The study population encompasses a broad array of patients across multiple continents and these subgroups provide ample opportunities for future research.
