BACKGROUND: Multiple sclerosis (MS) is a chronic autoimmune disease affecting the central nervous system (CNS), characterized by inflammation and neurodegeneration. The pathophysiology of MS, especially its progressive forms, involves various cellular components, including microglia, the primary resident immune cells of the CNS. This review discusses the role of microglia in neuroinflammation, tissue repair, and neural homeostasis, as well as their involvement in MS and explores potential therapeutic strategies targeting microglial function. METHODS: A literature search conducted in August 2023 and updated in March 2025, using the PubMed database, focused on articles relating to microglia and MS published in 2018-2025. Additionally, ongoing clinical trials of Bruton's tyrosine kinase (BTK) inhibitors were identified through the ClinicalTrials.gov website in November 2023 and updated in March 2025. RESULTS: Microglia are highly adaptive and exhibit various functional states throughout different life stages and play critical roles in neuroinflammation, tissue repair, and neural homeostasis. Their altered activity is a prominent feature of MS, contributing to its pathogenesis. Imaging techniques such as magnetic resonance imaging (MRI) and positron emission tomography (PET) provide insights into microglial activity in MS. BTK inhibitors and other novel treatments for MS, including masitinib and frexalimab, show promise in modulating microglial function and influencing the disease progression rate. CONCLUSIONS: The multifaceted roles of microglia in CNS development, immune surveillance, and particularly in the pathogenesis of MS highlight the potential of targeting microglial functions in MS treatment. Emerging research on the involvement of microglia in MS pathophysiology offers promising avenues for developing novel therapies, especially for progressive MS, potentially improving patient outcomes in this debilitating disease.

The highly contagious zoonosis coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was declared a pandemic by the World Health Organization on March 11, 2020, and has led to a global health crisis with nearly 777 million confirmed infections and over 7 million deaths worldwide by November 10, 2024.1-3 Over time, various variants emerged, with Omicron and its sublines dominating the world over the past 3 years.4 In addition, there is increasing evidence regarding the immune response of SARS-CoV-2 vaccines, especially for people with multiple sclerosis (MS) receiving disease-modifying therapies. Hence, with this review, we aim to provide an updated overview and recommendations for clinical practice regarding MS and SARS-CoV-2 vaccines, including efficacy and safety, SARS-CoV-2 variants, vaccine hesitancy, and the immune response under treatment with respective disease-modifying therapies.
BACKGROUND AND PURPOSE: The global burden of neurological diseases exceeds 43.1%, imposing a significant burden on patients, caregivers and society. This paper presents a roadmap to reduce this burden and improve brain health (BH) in Europe. METHODS: The roadmap is based on the European Academy of Neurology's (EAN) five-pillar BH strategy: advancing a global BH approach (P1), supporting policymaking (P2), fostering research (P3), promoting education (P4), and raising awareness of prevention and treatment (P5). It reviews current efforts, collaborations and future directions aligned with the WHO Intersectoral Global Action Plan (iGAP) for Neurological Disorders and suggests future initiatives and call for action. RESULTS: P1: Support WHO-iGAP through defined action points, international collaborations, in particular, the WHO BH Unit, and the EAN Brain Health Mission. P2: Collaborate with 48 national neurological societies to promote National Brain Plans (NBPs), addressing local needs, and improving access to care. P3: Advocate for more research funding; identify determinants of BH; develop preventive measures. P4: Provide educational opportunities for neurologists, public education programs, and advocacy training, including tools to educate the public. P5: Spearhead global awareness campaigns, organize public educational activities, and train BH advocates to contribute toward sustainable and long-term public health campaigns and policy engagement. CONCLUSIONS: The paper highlights the importance of a unified approach, integrating international collaborations and local initiatives, to improve BH outcomes based on the WHO-iGAP, and support sustainable development goals, in particular SDG 3: Good Health and Well-being and SDG 4: Quality Education.
BACKGROUND AND PURPOSE: Neurological disorders constitute a significant portion of the global disease burden, affecting >30% of the world's population. This prevalence poses a substantial threat to global health in the foreseeable future. A lack of awareness regarding this high burden of neurological diseases has led to their underrecognition, underappreciation, and insufficient funding. Establishing a strategic and comprehensive research agenda for brain-related studies is a crucial step towards aligning research objectives among all pertinent stakeholders and fostering greater societal awareness. METHODS: A scoping literature review was undertaken by a working group from the European Academy of Neurology (EAN) to identify any existing research agendas relevant to neurology. Additionally, a specialized survey was conducted among all EAN scientific panels, including neurologists and patients, inquiring about their perspectives on the current research priorities and gaps in neurology. RESULTS: The review revealed the absence of a unified, overarching brain research agenda. Existing research agendas predominantly focus on specialized topics within neurology, resulting in an imbalance in the number of agendas across subspecialties. The survey indicated a prioritization of neurological disorders and research gaps. CONCLUSIONS: Building upon the findings from the review and survey, key components for a strategic and comprehensive neurological research agenda in Europe were delineated. This research agenda serves as a valuable prioritization tool for neuroscientific researchers, as well as for clinicians, donors, and funding agencies in the field of neurology. It offers essential guidance for creating a roadmap for research and clinical advancement, ultimately leading to heightened awareness and reduced burden of neurological disorders.

BACKGROUND AND OBJECTIVES: Early treatment of multiple sclerosis (MS) reduces disease activity and the risk of long-term disease progression. Effectiveness of ocrelizumab is established in relapsing MS (RMS); however, data in early RMS are lacking. We evaluated the 4-year effectiveness and safety of ocrelizumab as a first-line therapy in treatment-naive patients with recently diagnosed relapsing-remitting MS (RRMS). METHODS: ENSEMBLE was a prospective, 4-year, international, multicenter, single-arm, open-label, phase IIIb study. Patients were treatment naive, aged 18-55 years, had early-stage RRMS with a disease duration ≤3 years, Expanded Disability Status Scale (EDSS) score ≤3.5, and ≥1 clinically reported relapse(s) or ≥1 signs of brain inflammatory activity on MRI in the prior 12 months. Patients received IV ocrelizumab 600 mg every 24 weeks. Effectiveness endpoints over 192 weeks were proportion of patients with no evidence of disease activity (NEDA-3; defined as absence of relapses, 24-week confirmed disability progression [CDP], and MRI measures, with prespecified MRI rebaselining at week 8), 24-week/48-week CDP and 24-week confirmed disability improvement, annualized relapse rate (ARR), mean change in EDSS score from baseline, and safety. Cognitive status, patient-reported outcomes, and serum neurofilament light chain (NfL) were assessed. Descriptive analysis was performed on the intention-to-treat population. RESULTS: Baseline characteristics (N = 678) were consistent with early-stage RRMS (n = 539 patients, 64.6% female, age 40 years and younger; median age: 31.0 years; duration since: MS symptom onset 0.78 years, RRMS diagnosis 0.24 years; mean baseline EDSS score [SD] 1.71 [0.95]). At week 192, most of the patients had NEDA-3 (n = 394/593, 66.4%), 85.0% had no MRI activity, 90.9% had no relapses, and 81.8% had no 24-week CDP over the study duration. Adjusted ARR at week 192 was low (0.020, 95% CI 0.015-0.027). NfL levels were reduced to and remained within the healthy donor range, by week 48 and week 192, respectively. No new or unexpected safety signals were observed. DISCUSSION: Disease activity based on clinical and MRI measures was absent in most of the patients treated with ocrelizumab over 4 years in the ENSEMBLE study. Safety was consistent with the known profile of ocrelizumab. Although this single-arm study was limited by lack of a parallel group for comparison of outcome measures, the positive benefit-risk profile observed may provide confidence to adopt ocrelizumab as a first-line treatment in newly diagnosed patients with early RMS. CLASSIFICATION OF EVIDENCE: This study provides Class IV evidence that adult patients with early-stage MS who were treatment naive maintained low disease activity (NEDA-3) over 4 years with ocrelizumab treatment; no new safety signals were detected.

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 AND PURPOSE: Centers for training in autonomic nervous system (ANS) disorders are not widely available and the recent coronavirus 2019 pandemic temporarily reduced training opportunities in autonomic medicine across European countries. Here we evaluated the current state of education, clinical skills and postgraduate educational preferences on ANS disorders of European neurology residents and consultants. METHODS: A 23-item questionnaire was developed and distributed online amongst European neurology residents and consultants via mailing lists of the European Academy of Neurology. The questions assessed demographics, current training opportunities and learning preferences in ANS disorders. Six multiple-choice questions were used to self-evaluate knowledge of ANS disorders. RESULTS: In all, 285 individuals answered the survey (60% female, mostly 25-34 years of age). All respondents considered clinical autonomic skills necessary for good clinical neurological practice, and 92% would like to increase their ANS knowledge. Female respondents and those who trained in Southern/Eastern/Greater Europe more frequently judged ANS skills important for clinical practice than male respondents (p = 0.012) and respondents from Northern/Western Europe (p = 0.011). Female and younger respondents felt less confident in managing ANS disorders (p = 0.001 and p < 0.001, respectively). Respondents below 45 years of age (p < 0.001) and those with lower confidence in managing ANS disorders (p = 0.004) were more likely to recommend that ANS education is embedded in the residency curriculum. CONCLUSIONS: Most European neurology residents and consultants reported a need for more autonomic education, with additional gender, age and regional differences. These findings underscore the importance of increasing the educational content on autonomic medicine in European medical and postgraduate curricula.

INTRODUCTION: Ocrelizumab is an approved intravenously administered anti-CD20 antibody for multiple sclerosis (MS). The safety profile and patient preference for conventional versus shorter ocrelizumab infusions were investigated in the ENSEMBLE PLUS study. METHODS: ENSEMBLE PLUS was a randomized, double-blind substudy to the single-arm ENSEMBLE study (NCT03085810), comparing outcomes in patients with early-stage relapsing-remitting MS receiving ocrelizumab 600 mg over the approved 3.5-h (conventional) versus 2-h (shorter) infusion. The primary endpoint was the proportion of patients with infusion-related reactions (IRRs) following the first randomized dose (RD); the secondary endpoint included IRR frequency at subsequent RDs. RESULTS: At first RD, the number of patients with an IRR in the conventional (101/373; 27.1%) versus shorter (107/372; 28.8%) infusion group was similar (difference, stratified estimates [95% CI]: 1.9% [- 4.4, 8.2]). Most IRRs (conventional: 99.4%; shorter: 97.7%) were mild/moderate. IRR frequency decreased over the course of RDs; three patients discontinued from the shorter infusion arm but continued with conventional infusion. Overall, > 98% of IRRs resolved without sequelae in both groups. Pre-randomization throat irritation was predictive of future throat irritation as an IRR symptom. Adverse events (AEs) and serious AEs were consistent with the known ocrelizumab safety profile. On completion of ENSEMBLE PLUS, most patients chose to remain on (95%) or switch to (80%) shorter infusion. CONCLUSION: ENSEMBLE PLUS demonstrates the safety and tolerability of shorter ocrelizumab infusions. Most patients remained on/switched to shorter infusion after unblinding; IRRs did not strongly influence patient decisions. CLINICAL TRIALS REGISTRATION: Substudy of ENSEMBLE (NCT03085810). REGISTRATION: March 21, 2017.

Multiple Sclerosis (MS) management in individuals aged 55 and above presents unique challenges due to the complex interaction between aging, comorbidities, immunosenescence, and MS pathophysiology. This comprehensive review explores the evolving landscape of MS in older adults, including the increased incidence and prevalence of MS in this age group, the shift in disease phenotypes from relapsing-remitting to progressive forms, and the presence of multimorbidity and polypharmacy. We aim to provide an updated review of the available evidence of disease-modifying treatments (DMTs) in older patients, including the efficacy and safety of existing therapies, emerging treatments such as Bruton tyrosine kinase (BTKs) inhibitors and those targeting remyelination and neuroprotection, and the critical decisions surrounding the initiation, de-escalation, and discontinuation of DMTs. Non-pharmacologic approaches, including physical therapy, neuromodulation therapies, cognitive rehabilitation, and psychotherapy, are also examined for their role in holistic care. The importance of MS Care Units and advance care planning are explored as a cornerstone in providing patient-centric care, ensuring alignment with patient preferences in the disease trajectory. Finally, the review emphasizes the need for personalized management and continuous monitoring of MS patients, alongside advocating for inclusive study designs in clinical research to improve the management of this growing patient demographic.

BACKGROUND: In 2018 multiple sclerosis (MS) care unit (MSCU) recommendations were defined. Nevertheless, the information on MS care, and whether MS centres fulfil the international recommendation is limited. Thus our objectives were to assess whether centres meet the MSCU recommendations and gain a comprehensive overview of MS care in Central-Eastern European countries. METHODS: A self-report questionnaire assessing aspects of the MSCU recommendations, disease-modifying therapy (DMT) and registry use and the patient number was assembled and sent to nine Central-Eastern European countries. Furthermore, one Danish and one German centre were contacted as a reference. RESULTS: In 9/9 countries, MS care was pursued in centres by MS neurologists and MS nurses. In Austria and the Czech Republic, management of MS was conducted under strict regulations displaying a referral centre system, fundamentally similar to but independent of the MSCU criteria. Several centres fulfilled all aspects of the MSCU criteria, while others had similar insufficiencies consisting of a speech therapist, continence, pain and spasticity specialist, neuro-ophthalmologist, and oto-neurologist. In 9/9 countries, DMTs were reimbursed. However, some centres did not provide every available DMT. A national registry was available in 4/9 countries with mandatory registry use only in Austria and the Czech Republic. CONCLUSION: In countries where MSCU recommendations are not fulfilled, a strictly regulated centre system similar to the Austrian and Czech model with a registry-based quality control might ensure appropriate care for people with MS.
