Background
Recent literature indicates that neuromyelitis optica spectrum disorder (NMOSD) patients commonly experience cognitive impairments (CI). This review aimed to compare cognitive functions between NMOSD patients and healthy controls (HCs) and synthesize the overall prevalence of CI in NMOSD patients.
Method
PubMed/MEDLINE, Embase, Scopus, and Web of Science were searched systematically up to March 24, 2025, to identify relevant articles evaluating the cognitive functions of NMOSD patients. Meta-analysis was conducted using the random-effect model to determine a) the pooled prevalence of CI in NMOSD patients and b) the pooled standard mean difference (SMD) of cognitive performance between NMOSD patients and HC, with their 95 % confidence interval by R software version 4.4.0.
Results
Sixty-three studies, encompassing 3370 NMOSD patients and 4641 HCs, met the inclusion criteria. Meta-analysis revealed that the pooled prevalence of CI was 45.4 % (95 %CI; 39.6 to 51.2, I2=88 %) among NMOSD patients. The analysis demonstrated that NMOSD patients had significant poor performances on Montreal Cognitive Assessment (MoCA) (SMD=-1.53, 95 % CI: -2.03 to -1.04, p < 0.001, I2=93 %), Brief Visuospatial Memory Test-Revised (BVMT-R) (SMD=-1.14, 95 % CI: -1.69 to -0.59, p < 0.001, I2=86 %), Mini Mental State Examination (MMSE) (SMD=-1.1, 95 % CI: -1.65 to -0.55, p < 0.001, I2=85 %), Symbol Digit Modalities Test (SDMT) (SMD=-1.03, 95 % CI: -1.37 to -0.69, p < 0.001, I2=92 %) than HCs.
Conclusion
This comprehensive review indicated that NMOSD patients exhibited worse cognitive performance compared to healthy individuals. Additionally, CI is often a complication of NMOSD. These findings accentuate the imperative of integrating cognitive assessments into the comprehensive evaluation of these patients.

Background
NfL and GFAP in blood are emerging as important biomarkers in MS. A urine-based assay could provide a simpler, non-invasive alternative; however, limited biomarker transfer into urine may pose a major challenge. This study aimed to evaluate the detectability and diagnostic potential of urinary and serum NfL and GFAP for distinguishing MS patients from healthy controls.
Methods
Urine and serum samples from patients with relapsing–remitting MS (RRMS; n = 62) and progressive MS (PMS; n = 17) were analyzed alongside healthy controls (n = 21). NfL and GFAP concentrations were quantified using bead-based immunoassays (Simoa). Pre-analytical validation included inter-/intra-assay precision, reproducibility, and parallelism. Creatinine ratios (CRs) were calculated to adjust for urine dilution.
Results
Urinary NfL and GFAP concentrations were detectable but overall low and fell below the assays’ validated detection range in most samples. Analyses restricted to valid measurements, as well as sensitivity analyses including all samples, revealed no significant group differences in urinary NfL, GFAP, or their CRs. Subgroup analyses of RRMS patients with or without relapse or MRI contrast enhancement showed similar results. A weak association between serum and urinary NfL was found in univariate regression but not for GFAP. In multivariate models, urinary creatinine concentration, reflecting urine dilution, was the strongest mediator of the measured urinary biomarker levels.
Conclusion
NfL and GFAP can be detected in urine using ultra-sensitive immunoassays; however, concentrations are very low and strongly influenced by urine dilution. Consequently, urinary NfL and GFAP currently lack reliability for distinguishing MS patients from healthy controls or for monitoring disease activity.
血液中的nfl和GFAP正在成为ms的重要生物标志物。基于尿液的检测可以提供一种更简单、无创的替代方法;然而,有限的生物标志物转移到尿液中可能构成主要挑战。本研究旨在评估尿液和血清NfL和GFAP的可检出性和诊断潜力,以区分MS患者和健康对照。方法对复发-缓解型多发性硬化(RRMS, n = 62)和进展型多发性硬化(PMS, n = 17)患者的尿液和血清样本与健康对照(n = 21)进行分析。使用基于头部的免疫测定法(Simoa)定量NfL和GFAP浓度。分析前验证包括测定间/测定内的精密度、重现性和平行性。计算肌酐比(CRs)以调整尿稀释。结果在大多数样品中,可检测到血清NfL和GFAP浓度,但总体较低,且低于该方法的有效检测范围。仅限于有效测量的分析,以及包括所有样本的敏感性分析,显示尿NfL、GFAP或其cr没有显著的组间差异。有或没有复发或MRI增强的RRMS患者的亚组分析显示了类似的结果。单变量回归发现血清和尿NfL之间存在弱关联,但GFAP没有。在多变量模型中,反映尿稀释度的尿肌酐浓度是测量尿液生物标志物水平的最强中介。结论超灵敏免疫法可检测尿中nfl和GFAP;然而,浓度很低,受尿液稀释的影响很大。因此,尿NfL和GFAP目前在区分MS患者和健康对照或监测疾病活动方面缺乏可靠性。

Idiopathic intracranial hypertension (IIH) is defined by elevated intracranial pressure without identifiable structural, infectious, or neoplastic cause. While the underlying pathophysiology remains unclear, emerging evidence suggests a potential role for autoimmune mechanisms, including antibodies against myelin oligodendrocyte glycoprotein (MOG). This retrospective study aimed to investigate the presence and clinical relevance of MOG-IgG antibodies in patients with IIH.
Methods
We included 58 consecutive patients diagnosed according to the current clinical criteria and divided them into three groups: MOG antibody-associated optic neuritis (MOG-ON, n = 19), MOG-positive IIH (MOG+ IIH, n = 10), and MOG-negative IIH (MOG-IIH, n = 29). MOG-IgG levels were measured using a live-cell-based assay. Clinical characteristics, cerebrospinal fluid (CSF) findings, visual assessments, cranial magnetic resonance imaging (MRI) results, and treatment responses were compared.
Results
MOG antibodies were detected in 25.6 % of the patients with IIH. MOG+ IIH patients were exclusively female and had higher rates of diplopia and acute symptom onset than MOG− IIH patients. MOG-ON patients had significantly lower CSF opening pressure. Visual acuity, OCT, and VEP abnormalities were more severe in the MOG-ON group, whereas there were no significant differences between MOG+ IIH and MOG− IIH. Some MRI findings related to IIH (e.g., transverse sinus stenosis) were more common in MOG− IIH.
Conclusion
MOG-IgG antibodies may be detected in a subset of IIH patients who exhibit distinct clinical features, suggesting a potential inflammatory or autoimmune etiology. Although a direct causal relationship could not be established, these findings support the need for further investigation into the immunological spectrum of IIH.
目的特发性颅内高压(IIH)是指没有明确的结构性、感染性或肿瘤性原因的颅内压升高。虽然潜在的病理生理机制尚不清楚,但新出现的证据表明其潜在作用与自身免疫机制有关,包括针对髓鞘少突胶质细胞糖蛋白(MOG)的抗体。本回顾性研究旨在探讨MOG-IgG抗体在IIH患者中的存在及其临床意义。方法纳入58例符合现行临床诊断标准的连续患者,将其分为MOG抗体相关视神经炎(MOG- on, n = 19)、MOG阳性IIH (MOG+ IIH, n = 10)和MOG阴性IIH (MOG-IIH, n = 29) 3组。采用活细胞法测定MOG-IgG水平。临床特征、脑脊液(CSF)检查结果、视觉评估、颅磁共振成像(MRI)结果和治疗反应进行比较。结果25.6%的IIH患者检出烟雾抗体。MOG+ IIH患者均为女性,复视率和急性症状发作率均高于MOG−IIH患者。MOG-ON患者脑脊液开口压明显降低。MOG- on组的视力、OCT和VEP异常更为严重,而MOG+ IIH组和MOG- IIH组的差异无统计学意义。一些与IIH相关的MRI表现(如横窦狭窄)在MOG−IIH中更为常见。结论mog - igg抗体可能在IIH患者亚群中检测到,这些患者表现出不同的临床特征,提示潜在的炎症或自身免疫性病因。虽然不能建立直接的因果关系,但这些发现支持了进一步研究IIH免疫学谱的必要性。

Background
Genetic variants in Fc gamma receptors (FcγRs) have been implicated in the therapeutic failure of monoclonal antibodies. Natalizumab (NTZ), a monoclonal antibody widely used in the treatment of multiple sclerosis (MS), prevents immune cell migration into the central nervous system, thereby reducing inflammation and demyelination. Despite its high efficacy, a subset of patients does not respond to NTZ, with single nucleotide polymorphisms (SNPs) in FcγRs emerging as potential pharmacogenetic biomarkers.
Methods
In this study, we evaluated patients with relapsing-remitting MS diagnosed according to the McDonald criteria and treated with NTZ. Genotyping of FCGR2A (rs1801274) and FCGR3A (rs396991) was performed using TaqMan-PCR allelic discrimination. Cytokine levels were quantified using x-MAP technology.
Results
Of the 116 patients analyzed, 13 were classified as non-responders. Logistic regression adjusted for sex and age revealed that the FCGR2A AG genotype was significantly associated with a reduced risk of therapeutic failure (OR = 0.044; p = 0.014), while for FCGR3A, the AC genotype was also associated with a protective effect (OR = 0.077; p = 0.025). No significant effects of age or sex were observed in either model. Receiver Operating Characteristic (ROC) analysis showed that the FCGR2A rs1801274 GG genotype had weak predictive value for therapeutic failure, whereas FCGR3A rs396991 AA had modest discriminatory power. Additionally, these genotypes were associated with reduced levels of specific pro-inflammatory cytokines.
Conclusion
The FCGR2A AG and FCGR3A AC genotypes were associated with a lower risk of NTZ treatment failure, suggesting that FcγR polymorphisms may serve as biomarkers for therapeutic response in MS.

Aim
In a large UK multiple sclerosis (MS) cohort, we examined work status and how it changed over follow-up, identifying demographic, clinical and other factors associated with these transitions.
Methods
Participants of the Trajectories of Outcome in Neurological Conditions-MS study completed questionnaires on demographics, work instability, disability, fatigue, mood and quality of life at baseline and follow-up to explore work disability (stopping), discontinuity (retiring early) and drift (downgrading). Regression and Classification and Regression Tree (CART) analysis examined predictive factors.
Results
Among 1035 subjects aged 20–60 years in paid work at baseline with mean follow-up 22.7 months, net annual increases were 4.0 % for work disability, 3.1 % for discontinuity and 1.8 % for drift. Risk of work disability was increased by age, work instability and for part-time work, female sex. The risk of drift was 3.9 times higher for females; work instability increased drift for all subjects. Reverse work disability and drift were also observed, i.e. returning to employment or upgrading work. Discontinuity was influenced by secondary progressive subtype, impaired cognition, more comorbidities, and reduced by disease modifying therapy use. CART analysis showed that risk of job loss could be predicted using age, EDSS and sickness absence information, and of medical retirement using the above three factors and MS subtype.
Conclusions
Screening for people with MS at greater risk of losing employment could be readily done in clinical practice, facilitating further discussion with the multidisciplinary team and referral to support services as appropriate.

Background
Breast cancer (BC) is one of the most prevalent cancers among women in the worldwide. Multiple sclerosis (MS) plays an important role not only in pathogenesis but also in the antitumour response. Therefore, we investigated the causal relationship and pathogenesis between BC and MS via integrated Mendelian randomization (MR) and bioinformatics analysis.
Methods
We performed MR analyses to investigate the potential causal relationship between BC and MS via the IEU database. A comprehensive strategy among least absolute shrinkage and selection operator regression, support vector machine, univariate and multivariate Cox regression analysis, time ROC regression, and survival analysis was adopted to construct and validate the prognostic model. Immune cell infiltration and chemotherapy sensitivity were used to evaluate the prognostic model.
Results
MR analysis revealed that MS was causally associated with the incidence risk of BC. Patients in the high-risk group were related to worse survival, immune infiltration, and increased sensitivity to paclitaxel, methotrexate, doxorubicin, gemcitabine, and sunitinib. Furthermore, KLRC1 was expressed at low levels in BC tissues and correlated with poor prognosis and immune cell infiltration.
Conclusions
Our findings suggest a potential causal association between MS and BC. KLRC1 is a robust and promising biomarker for predicting the prognosis of patients with MS and BC.

Introduction
Multiple sclerosis (MS) is a chronic, inflammatory, autoimmune, and demyelinating disease of the central nervous system. Disease progression increases dysphagia, raising risks of malnutrition, dehydration, and respiratory complications, directly impacting nutrition management.
Objectives
(I) To analyse the anthropometric profiles and body composition of adults with MS; (II) to determine the prevalence of dysphagia according to disease duration; (III) to examine dietary intake and eating habits; (IV) to identify potential alterations in taste perception.
Methodology
A descriptive-analytical study included 14 MS patients (7 women, 7 men; median age 46.9 ± 13.5 years) from Granada. Anthropometry and body composition were assessed using bioelectrical impedance analysis (TANITA). Dysphagia risk was evaluated using the Yale Swallow protocol, TWST, and TOMASS protocols, and basic taste perception was examined. Dietary intake was recorded over 3-day (24-hour recall) and food frequency questionnaire (FFQ); data were processed with Dietowin® software.
Results
A total of 66.7 % presented with overweight or obesity (median BMI 28.1 kg/m²). The prevalence of mixed dysphagia was 71.4 %, with no significant differences according to disease duration, except for mixed dysphagia (p = 0.018). Over 70 % of patients had insufficient intake of energy, fibre, and micronutrients (calcium, iron, potassium, magnesium). Taste alterations were observed in 57.1 % of patients, particularly in the perception of sweetness (78.6 %).
Conclusions
Patients with MS and dysphagia exhibit a high prevalence of overweight, inadequate dietary intake, and taste alterations. These findings highlight the need for comprehensive, multidisciplinary interventions involving speech therapy and nutritional support, to optimise nutritional status and quality of life.

Objectives
The Marburg variant of multiple sclerosis (MvMS) is a rare, rapidly progressive demyelinating disorder characterized by an acute, monophasic onset with early, severe disability or death within weeks to months. In this systematic review, we aimed to: (I) describe patient characteristics and therapies used; (II) categorize outcomes; and (III) synthesize therapy–outcome relationships to guide practical management.
Methods
We performed a PRISMA-guided systematic review of published MvMS cases reporting treatment and outcomes, and present an illustrative pediatric case from our center.
Results
Across databases, 144 records were identified (PubMed 34; Scopus 74; WoS 36), out of which 22 articles met inclusion criteria. Among the 23 patients synthesized (22 published cases plus our pediatric case), median age was 32 years (range 14–63), with a female predominance (78 %). Nearly all patients received high-dose corticosteroids (22/23; 96 %). Additional therapies were common and variably combined: plasma exchange (14/23; 61 %), IVIg (8/23; 35 %), cyclophosphamide (10/23; 43 %), mitoxantrone (7/23; 30 %), any cytotoxic (cyclophosphamide and/or mitoxantrone) (15/23; 65 %), B-cell–depleting therapy (rituximab/ocrelizumab) (4/23; 17 %), alemtuzumab (1/23; 4 %), and natalizumab (1/23; 4 %); doses were inconsistently reported across studies, and order/timing of therapies varied widely. Overall outcomes were death in 6/23 (26 %), stable deficit in 4/23 (17 %), improvement in 9/23 (39 %), and near-complete recovery in 4/23 (17 %). We also propose a set of pragmatic, evidence-based diagnostic criteria. These criteria classify cases as Definite, Probable, or Possible Marburg variant MS based on fulminant clinical course, characteristic MRI patterns, CSF/serologic exclusion of mimics, and—when available—pathological confirmation.
Conclusion
While no single regimen was uniformly effective, our three-group analysis suggests a stepwise strategy: steroids ± plasma exchange alone were often insufficient; adding a cytotoxic agent with dual B- and T-cell activity (cyclophosphamide or mitoxantrone) was associated with more frequent improvement; and the highest proportion of improvement occurred when dual-arm cytotoxic therapy was combined with a B-cell–directed/lymphocyte-depleting agent.

Background
Cladribine Tablets (CladT) have emerged as a potent disease-modifying therapy (DMT) for relapsing multiple sclerosis (Pittock et al., 2019. While their efficacy and safety profiles have been well-documented in Western populations, there is a paucity of region-specific guidelines for their use in the Asia-Pacific context. This manuscript presents a consensus developed by Asia-Pacific experts, aiming to provide practical recommendations for the clinical application of CladT in this region.
Methods
A steering committee (SC) comprising four multiple sclerosis (Pittock et al., 2019one international and three from the APAC region—led an advisory board and developed 16 clinical questions regarding the practical use of CladT. To address these questions, statements were formulated based on available evidence, expert insights, and perspectives from the SC, along with input from an extended faculty of six MS experts representing in total nine APAC countries. Consensus on the recommendations was established when at least 75 % of respondents rated their agreement between 7 and 9 on a 9-point scale.
Results
A total of 16 clinical statements were drafted, and consensus was reached on 15 of them. The recommendations covered key aspects of CladT use, including indications for treatment initiation in both treatment-naïve and previously treated patients, strategies for managing disease activity over time, long-term safety considerations, and the role of CladT in special populations. CladT were recognized as an effective high-efficacy therapy for both highly and moderately active RMS, with robust long-term efficacy and safety profiles. It was also identified as a suitable option for patients requiring minimal hospital visits and those with limited access to healthcare facilities. While there was strong agreement on its use in treatment-naïve and early MS patients as well as a switch therapy, no consensus was reached on using CladT as a first-switch option for patients experiencing breakthrough disease on high-efficacy therapies. Recommendations also emphasized the importance of lymphocyte monitoring, appropriate patient selection, and the possibility of additional treatment courses beyond Year 5 in selected cases.
Conclusion
The consensus encompasses patient selection criteria, therapeutic strategies, monitoring protocols, and safety considerations, tailored to the unique demographic and healthcare landscapes of APAC countries.
背景克拉德滨片(CladT)已成为治疗复发性多发性硬化症的有效疾病修饰疗法(DMT) (Pittock et al., 2019)。虽然它们在西方人群中的有效性和安全性已经得到了充分的证明,但在亚太地区的使用中缺乏针对特定区域的指导方针。本文提出了亚太地区专家达成的共识,旨在为CladT在该地区的临床应用提供实用建议。方法由4名多发性硬化症患者(Pittock et al., 2019)、1名国际患者和3名亚太地区患者组成的指导委员会(SC)领导了一个咨询委员会,并制定了16个关于CladT实际应用的临床问题。为了解决这些问题,我们根据现有的证据、专家的见解和SC的观点,以及来自亚太地区9个国家的6名MS专家的意见,制定了声明。当至少75%的受访者在9分制中对他们的同意进行7到9分的评分时,就建立了对这些建议的共识。结果共起草临床陈述16份,达成共识15份。这些建议涵盖了CladT使用的关键方面,包括treatment-naïve和先前治疗过的患者开始治疗的适应症,长期管理疾病活动的策略,长期安全性考虑以及CladT在特殊人群中的作用。CladT被认为是一种有效的治疗高度和中度活性RMS的高效疗法,具有强大的长期疗效和安全性。它还被确定为需要最少住院次数的患者和获得保健设施的机会有限的患者的合适选择。虽然对于在treatment-naïve和早期MS患者中使用CladT以及作为一种转换疗法已经达成了强烈的共识,但对于使用CladT作为在高效疗法中经历突破性疾病的患者的第一转换选择,尚未达成共识。建议还强调了淋巴细胞监测的重要性,适当的患者选择,以及在选定病例中超过5年的额外治疗课程的可能性。结论共识包括患者选择标准、治疗策略、监测方案和安全考虑,针对亚太地区国家独特的人口统计学和医疗保健景观量身定制。

Background
Integrating clinical findings with neuroradiological changes is a crucial skill in neurology, particularly for diagnosis. Multiple Sclerosis (MS) lesions in the brainstem are rarely asymptomatic, leading to unique and often localised clinical syndromes. MS lesions exhibit a characteristic perivenular distribution, which in the brainstem is imprinted by the consistent topography of the penetrating veins.
Objective
This review provides an integrative perspective on the anatomical patterns of MS lesions in the brainstem (midbrain, pons, and medulla). It correlates specific clinical syndromes with radiological appearances, aiding in both diagnosis and functional localisation.
Methods
We searched the available literature using keywords related to the three brainstem sections (midbrain, pons, medulla) and eloquent anatomical locations (medial longitudinal fasciculus, cerebellar peduncle, nerve fascicle, aqueduct, area postrema), aiming to correlate specific radiological patterns of MS lesions with their consistent clinical syndromes as reported in the literature.
Summary of Key Findings
Brainstem MS lesions often cause irritative symptoms rather than full functional loss. Unlike other conditions, visible MS lesions on MRI rarely disappear and usually remain as silent lesions following an acute event. The consistent venous architecture creates specific radiological patterns that link to distinct clinical presentations. In contrast, inflammatory disorders like NMOSD and MOGAD cause more aggressive and extensive dysfunction.
Conclusion
The visual details of MS brainstem lesions reflect their close relationship to venous anatomy, which can be anticipated even when the central vein sign is not directly visualised. Recognising these specific clinical-radiological syndromes provides a unique and insightful diagnostic tool for MS, underscoring the value of strong functional and radiological-anatomical interpretation skills in clinical neurology.
