    Abstract Background: Radiologically isolated syndrome (RIS) patients might have psychiatric and cognitive deficits, which suggests an involvement of major resting-state functional networks. Notwithstanding, very little is known about the neural networks involved in RIS.
    Objective: To examine functional connectivity differences between RIS and healthy controls using resting-state functional magnetic resonance imaging (fMRI).
    Methods: Resting-state fMRI data in 25 RIS patients and 28 healthy controls were analyzed using an independent component analysis; in addition, seed-based correlation analysis was used to obtain more information about specific differences in the functional connectivity of resting-state networks. Participants also underwent neuropsychological testing.
    Results: RIS patients did not differ from the healthy controls regarding age, sex, and years of education. However, in memory (verbal and visuospatial) and executive functions, RIS patients' cognitive performance was significantly worse than the healthy controls. In addition, fluid intelligence was also affected. Twelve out of 25 (48%) RIS patients failed at least one cognitive test, and six (24.0%) had cognitive impairment. Compared to healthy controls, RIS patients showed higher functional connectivity between the default mode network and the right middle and superior frontal gyri and between the central executive network and the right thalamus (
    Conclusion: RIS patients had abnormal brain connectivity in major resting-state neural networks and worse performance in neurocognitive tests. This entity should be considered not an "incidental finding" but an exclusively non-motor (neurocognitive) variant of multiple sclerosis.

    Abstract Background: Lymphopenia is a major concern in MS patients treated with dimethyl-fumarate (DMF) as it increases the risk of progressive multifocal leukoencephalopathy. A pronounced reduction in absolute lymphocyte counts (ALCs) early after treatment initiation has been suggested to be associated with the occurrence of lymphopenia thereafter.
    Objectives: To identify risk factors for DMF-induced lymphopenia and evaluate whether the degree of decrease in the ALCs three months after initiation of DMF treatment is a predictor of the subsequent development of lymphopenia.
    Methods: In this real-world Spanish prospective multicenter study conducted in MS patients who started DMF between 2014 and 2019, we analyzed the association between DMF-related lymphopenia and the percentage of early ALCs decline using regression models, considering both, significant lymphopenia (grades 2 + 3) and severe lymphopenia (grade 3). The cutoff values of early ALCs declines were obtained using the ROC curve.
    Results: Among 532 MS patients treated with DMF, 193 (36.3%) developed any grade of lymphopenia. Older age and lower ALCs at treatment onset predicted the risk for lymphopenia but the best predictive risk factor was the reduction of ALCs within the three first months of treatment. Specifically, a reduction in ALCs≥21.2% was associated with a 6.5-fold higher risk of developing significant lymphopenia, and a decrease in ALCs≥40.2% with a 12.7-fold higher risk of developing severe lymphopenia.
    Conclusions: A pronounced reduction in ALCs early after initiation of DMF in MS patients is the best predictive risk factor for the subsequent development of significant lymphopenia.

    Abstract Objective: To assess the effectiveness and safety of fingolimod use in a Spanish clinical practice setting.
    Methods: Retrospective study with multiple sclerosis patients who received at least 1 fingolimod dose between January 2004 and January 2015. Effectiveness and safety data were collected during the entire treatment of each patient. Analysis was performed for the total population and stratified according to prior treatment, sex, and age at treatment initiation.
    Results: A total of 167 patients were included, 50.9% had prior immunomodulator use, 33.5% natalizumab use, and 15.6% were naive patients. The annual relapse rate (ARR) decreased for the total population at month 12 (62%) and month 24 (84%) (P < 0.0001, in both cases); for naive patients (P < 0.05) and patients with prior immunomodulator use (P < 0.0001); for patients with prior natalizumab use, the ARR kept low after treatment initiation (0.23). After 24 months, the proportion of relapse-free patients was 70% or greater and disability progression-free patients was 80% or greater. No significant differences were observed when the results were compared by prior treatment, sex, or age. Thirty-two patients (19.2%) reported adverse drug reactions and 9.6% discontinued: 4.8% due to adverse drug reactions and 4.8% for lack of effectiveness.
    Conclusions: The results support fingolimod use due to clinical effectiveness, tolerability, and ease of administration.

    Abstract Background: Eyelid nystagmus is a rare clinical phenomenon described mostly related to brainstem or cerebellum lesions. The mechanism of this phenomenon is incompletely understood.
    Patients and methods: We report 2 cases of eyelid nystagmus induced by carbamazepine and oxcarbazepine intoxication.
    Conclusions: Carbamazepine and derivatives may induce eyelid nystagmus in the setting of acute intoxication. To the best of our knowledge, these are the first cases of drug-related eyelid nystagmus.
