Introduction
Cognitive impairment (CI) has a prevalence of 45–70% in people with multiple sclerosis (MS), producing a negative impact on their quality of life, personal life, and work. Early ...detection of CI has become an important aspect to be considered for an adequate follow-up, to optimize social adaptation and to implement specific cognitive rehabilitation strategies. The aim of this work is to propose a suitable cognitive evaluation of patients with MS based on available and efficient tools for diagnosis and monitoring purposes well supported by literature review and clinical experience.
Methods
A multidisciplinary panel of professionals from the field of neurology, neuropsychology, and neuroimaging performed a literature review of the topic of cognitive impairment assessment. This was combined and completed with their clinical experience to produce a set of recommendations.
Results
Some limitations to cognitive evaluation are described: shortage of time and resources during the neurology consultation, scarceness or absence of specialized professionals’ availability, importance of tests adaptation, and doubts about its use to define therapeutic efficiency. We recommend a baseline and annual screening evaluation, and we suggest a baseline and periodic neuropsychological assessment. The latter ought to change to a recommendation with the presence of either positive screening test, or subjective to cognitive complaints, screening-test results and patient or family report mismatch, or in specific social/work situations.
Conclusions
Cognitive evaluation should be performed on all patients diagnosed with MS and throughout follow-up. It is necessary to support the creation of multidisciplinary MS teams to optimize the evaluation and follow-up of MS patients.

Multiple sclerosis (MS) is primarily an inflammatory and degenerative disease of the central nervous system, triggered by unknown environmental factors in patients with predisposing genetic risk ...profiles. The prevention of neurological disability is one of the essential goals to be achieved in a patient with MS. However, the pathogenic mechanisms driving the progressive phase of the disease remain unknown. It was described that the pathophysiological mechanisms associated with disease progression are present from disease onset. In daily practice, there is a lack of clinical, radiological, or biological markers that favor an early detection of the disease's progression. Different definitions of disability progression were used in clinical trials. According to the most descriptive, progression was defined as a minimum increase in the Expanded Disability Status Scale (EDSS) of 1.5, 1.0, or 0.5 from a baseline level of 0, 1.0-5.0, and 5.5, respectively. Nevertheless, the EDSS is not the most sensitive scale to assess progression, and there is no consensus regarding any specific diagnostic criteria for disability progression. This review document discusses the current pathophysiological concepts associated with MS progression, the different measurement strategies, the biomarkers associated with disability progression, and the available pharmacologic therapeutic approaches.
Limited information is available on how neurologists make therapeutic decisions in neuromyelitis optica spectrum disorder (NMOSD), especially when new treatments with different mechanisms of action, ...administration, and safety profile are being approved. Decision-making can be complex under this uncertainty and may lead to therapeutic inertia (TI), which refers to lack of treatment initiation or intensification when therapeutic goals are not met. The study aim was to assess neurologists' TI in NMOSD.
An online, cross-sectional study was conducted in collaboration with the Spanish Society of Neurology. Neurologists answered a survey composed of demographic characteristics, professional background, and behavioral traits. TI was defined as the lack of initiation or intensification with high-efficacy treatments when there is evidence of disease activity and was assessed through five NMOSD aquaporin-4 positive (AQP4+) simulated case scenarios. A multivariate logistic regression analysis was used to determine the association between neurologists' characteristics and TI.
A total of 78 neurologists were included (median interquartile range IQR age: 36.0 29.0-46.0 years, 55.1% male, median IQR experience managing demyelinating conditions was 5.2 3.0-11.1 years). The majority of participants were general neurologists (59.0%) attending a median (IQR) of 5.0 NMOSD patients (3.0-12.0) annually. Thirty participants (38.5%) were classified as having TI. Working in a low complexity hospital and giving high importance to patient's tolerability/safety when choosing a treatment were predictors of TI.
TI is a common phenomenon among neurologists managing NMOSD AQP4+. Identifying TI and implementing specific intervention strategies may be critical to improving therapeutic decisions and patient care.
•The neuromyelitis optica spectrum disorder (NMOSD) is a rare chronic autoimmune disease where even a single relapse can severely impact patient autonomy and quality of life.•Treatment decisions in ...NMOSD have become more complicated with the recent approval of therapies with different mechanisms of action, safety risk, and routes of administration.•Understanding neurologists’ preferences for NMOSD treatment characteristics may be useful to improve the decision-making process in a context of a lack of standardised treatment guidelines.
The treatment landscape for neuromyelitis optica spectrum disorder (NMOSD) has changed in recent years with the approval of therapies with different efficacy, safety and administration profiles.
The aim of this study was to assess neurologists’ preferences for different NMOSD treatment attributes using conjoint analysis (CA).
We conducted an online, non-interventional, cross-sectional study in collaboration with the Spanish Society of Neurology. Our CA assessed five drugs’ attributes: prevention of relapse, prevention of disability accumulation, safety risk, management during pregnancy, and route and frequency of administration. Participants were presented with eight hypothetical treatment scenarios to rank based on their preferences from the most preferred to the least. An ordinary least squares method was selected to estimate weighted preferences.
A total of 104 neurologists were included. Mean age (standard deviation-SD) was 37.7 (10.3) years, 52.9 % were male, and median time (interquartile range) of experience managing NMOSD was 5.0 (2.9, 10.8) years. Neurologists placed the greatest importance on efficacy attributes, time to relapse (44.1 %) being the most important, followed by preventing disability accumulation (36.8 %). In contrast, route and frequency of administration (4.6 %) was the least important characteristic. Participants who prioritised efficacy attributes felt more comfortable in decision-making, had fewer past experiences of care-related regret and a lower attitude to risk taking than their counterparts.
Neurologists’ treatment preferences in NMOSD were mainly driven by efficacy attributes. These results may be useful to design policy decisions and treatment guidelines for this condition.
Background: Severe cases of lymphopenia have been reported during siponimod clinical trials, which may negatively impact its benefit/risk profile. Objective: We aimed to evaluate the incidence of ...lymphopenia following the initiation of siponimod treatment in clinical practice. The secondary objectives included the analysis of factors predisposing to and the clinical relevance of lymphopenia events. Methods: In this multicenter retrospective cohort study, information collected from the medical records of 129 patients with MS from 15 tertiary hospitals in Spain who initiated treatment with Siponimod were followed-up for at least 3 months, including at least one lymphocyte count evaluation per patient. Results: Of the 129 patients, 121 (93.6%) reported lymphopenia events, including 110 (85.3%) with grade ≤ 3 and 11 (8.5%) with grade 4 lymphopenia, higher than those reported in the pivotal clinical trial (73.3% and 3.3% for grade ≤ 3 and grade 4 lymphopenia, respectively). The study included an unexpectedly high proportion of male subjects (72.9%), which might have led to an underestimation of the actual magnitude of the risk. Conclusions: In this study, the incidence and severity of lymphopenia after starting siponimod treatment were higher than those reported in previous clinical trials. Therefore, our results reinforce the need for the closer monitoring of novel MS drugs in clinical practice, as well as larger and longer follow-up studies to properly characterize this risk.
Abstract Current safety recommendations for multiple sclerosis (MS) patients who are considered for natalizumab do not specify how to screen for latent tuberculosis (LTB). Only chest X-ray is ...recommended as a routine, and follow-up depends on its results. The incidence of TB in Spain is high and the risk of a LTB reactivation due to natalizumab is unknown. Our objective is to describe in our clinical practice if following the current recommendations for the MS population on natalizumab allows identifying patients with a LTB, as well as the risk for TB reactivation. Our study demonstrated that, in our environment, current recommendations are not sensitive enough to identify cases of LTB, though no cases of active TB were observed. Considering the lack of documented active TB cases worldwide among natalizumab patients, we suggest that these safety measures are probably unnecessary, even in countries with a high TB incidence.
