    Abstract Introduction: In recent years, different studies have highlighted the importance of B cells in the pathophysiology of multiple sclerosis (MS): they secrete cytokines to modulate the inflammatory environment, present antigens for the activation of T lymphocytes, and they secrete antibodies contributing to the destruction of the myelin sheath. Combined, these findings have lead to new possible means for treating MS.
    Areas covered: In this review, we provide an up-to-date overview of the characteristics of ofatumumab (aka Kesimpta), and the differences between this drug and the other anti-CD20 monoclonal antibodies used to treat MS.
    Expert opinion: The evolution of disease-modifying treatment algorithms in MS underlines the importance of starting treatment as soon as the diagnosis is defined, and with adequate 'treatment intensity.' Monoclonal antibodies and other aggressive treatments are now considered as an option at the clinical presentation of the disease, based to the prognostic profile emerging through clinical and paraclinical investigations. The recent adoption of new diagnostic criteria allows for the early diagnosis of MS. This, together with the availability of disease-modifying therapies (DMTs), such as ofatumumab, with a good efficacy/safety profile and which are easy to administer, could contribute to significant improvements in the long-term prognosis of MS.

    Abstract Cognitive impairment affects 34-65% of People with Multiple Sclerosis (PwMS), significantly impacting their quality of life. Clinicians routinely address cognitive deficits with in-clinic neuro-behavioural interventions, but accessibility issues exist. Given these challenges, coupled with the lifelong need for continuous assistance in PwMS, researchers have underscored the advantageous role of telerehabilitation in addressing these requirements. Nonetheless, the feasibility and efficacy of home-based cognitive remediation remain to be firmly established. In this narrative review, we aimed to investigate the feasibility and efficacy of digital telerehabilitation for cognition in PwMS. Thirteen relevant studies were identified and carefully assessed. Regarding the feasibility of cognitive telerehabilitation, evidence shows adherence rates are generally good, although, surprisingly, not all studies reported measures of compliance with the cognitive training explored. Considering the efficacy of rehabilitative techniques on cognitive performance in PwMS, findings are generally inconsistent, with only one study reporting uniformly positive results. A range of methodological limitations are reported as potential factors contributing to the variable results. Future research must address these challenges, as more rigorous studies are required to draw definitive conclusions regarding the efficacy of home-based cognitive remediation in PwMS. Researchers must prioritise identifying optimal intervention approaches and exploring the long-term effects of telerehabilitation.

    Abstract We tested whether dispersible L-dopa has acute effects on event-related desynchronization (ERD) of the mu rhythm in patients with idiopathic Parkinson's disease (IPD). ERD to voluntary movement is delayed in akinetic IPD patients and improves after chronic L-dopa treatment. We evaluated ERD to self-paced finger movement in 14 IPD patients (before and 30-40 min after oral administration of dispersible L-dopa) and in 10 normal subjects. Sensorimotor ERD onset contralateral to movement was significantly delayed in IPD patients compared to normal subjects. This abnormality was no longer significant after L-dopa treatment. We conclude that a single dose of dispersible L-dopa can improve not only motor performance in IPD patients but also the timing of cortical activation of sensorimotor areas during motor programming.

    Abstract Background: Covid-19 pandemic greatly impacted on the healthcare systems worldwide with negative consequences on several aspects of clinical populations. For neurological chronic conditions such as Multiple Sclerosis (MS), rehabilitation activities have been suspended or postponed during the pandemic. Rehabilitation is crucial for people with MS (PwMS) because it promotes recovery from relapses and maximizes opportunities for social participation. To better understand the impact of Covid-19 emergency on rehabilitation services for MS, the European network for rehabilitation in MS (RIMS) disseminated a survey to healthcare professionals (HPs) and representatives of the MS rehabilitation services (RSs), to explore the two different perspectives on the delivery of rehabilitation in usual circumstances and during the Covid-19 emergency.
    Methods: The online survey was distributed from July 9th to September 20th, 2020. Besides general information on the responders (e.g. location of center, and memebership to RIMS), information was collected on usual service delivery (e.g. settings, specialities, and types of treatment), the impact of Covid-19 circumstances (e.g. restrictions, use of personal protective equipment, and impact on work), and the use of technologiesin rehabilitation.
    Results: Twenty-two representatives of MS rehabilitation services (RSs)and 143 health care professionals (HPs) responded. Most of RSs and HPs worked in services specialized for MS including a mixture of all usual rehabilitation settings (i.e. inpatient, outpatient and community setting). The majority of services adopted a multidisciplinary framework, including physical therapy, occupational therapy, social service, speech and language therapy, psychological support, dietary interventions, medical management, vocational rehabilitation and cognitive rehabilitaton. Overall, most of responders indicated they did not use technologies in their practice (e.g. for treatment or assessment). However, depending on the type of technology a low-to-medium percentage of responders declared to use some technologies before Covid-19 crisis (5-55% for RSs and 12-53% for HPs) and a low percentage planned the use after pandemic (0-14% for RSs and 1-10% for HPs). Moreover, for the responders the most feasible interventions deliverable through tele-rehabilitation were psychological support and dietary interventions, with psychological support considered the most necessary intervention to be remotely implemented. Moderate feasibility (30-60%) was reported for hands-off interventions (e.g. aerobic exercise and cognitive rehabilitation) whereas low feasibility (<30%) was reported for hands-on interventions. Feasibility was especially low when tools were used that are not adaptable at-home (e.g. hyperbaric oxygen therapy).
    Conclusion: The Covid-19 pandemic has stimulated the MS healthcare professionals to find new solutions to deliver alternative interventions to PwMS. In this context, the role of telemedicine is crucial to continue rehabilitation services at home, and limit exposure to infection. However, most of healthcare professionals have not incorporated the use of technologies. Therefore, the implementation of digital health solutions in the clinical practice needs more attention towards education on the potentials of technologies for rehabilitation and simplification of the national healthcare system reimbursement procedures for the rehabilitation technologies use.

    Abstract Introduction: Visual evoked potentials (VEPs) are a non-invasive technique routinely used in clinical and preclinical practice. Discussion about inclusion of VEPs in McDonald criteria, used for Multiple Sclerosis (MS) diagnosis, increased the importance of VEP in MS preclinical models. While the interpretation of the N1 peak is recognized, less is known about the first and second positive VEP peaks, P1 and P2, and the implicit time of the different segments. Our hypothesis is that P2 latency delay describes intracortical neurophysiological dysfunction from the visual cortex to the other cortical areas.
    Methods: In this work, we analyzed VEP traces that were included in our two recently published papers on Experimental Autoimmune Encephalomyelitis (EAE) mouse model. Compared with these previous publications other VEP peaks, P1 and P2, and the implicit time of components P1-N1, N1-P2 and P1-P2, were analyzed in blind.
    Results: Latencies of P2, P1-P2, P1-N1 and N1-P2 were increased in all EAE mice, including group without N1 latency change delay at early time points. In particular, at 7 dpi the P2 latency delay change was significantly higher compared with N1 latency change delay. Moreover, new analysis of these VEP components under the influence of neurostimulation revealed a decrease in P2 delay in stimulated animals.
    Discussion: P2 latency delay, P1-P2, P1-N1, and N1-P2 latency changes which reflect intracortical dysfunction, were consistently detected across all EAE groups before N1 change. Results underline the importance of analyzing all VEP components for a complete overview of the neurophysiological visual pathway dysfunction and treatment efficacy.

    Abstract Neurodegeneration is the main contributor to disability accumulation in multiple sclerosis. Previous studies in neuro-ophthalmology have revealed that neurodegeneration in multiple sclerosis also affects the neuro-retina. Optical coherence tomography has been used to measure thinning of retinal layers, which correlates with several other markers for axonal/neuronal loss in multiple sclerosis. However, the existing analytical tools have limitations in terms of sensitivity and do not provide topographical information. In this study, we aim to evaluate whether voxel-based morphometry can increase sensitivity in detecting neuroaxonal degeneration in the retina and offer topographical information. A total of 131 people with multiple sclerosis (41 clinically isolated syndrome, 53 relapsing-remitting and 37 progressive multiple sclerosis) and 50 healthy subjects were included. Only eyes with normal global peripapillary retinal nerve fibre layer thickness and no history of optic neuritis were considered. Voxel-based morphometry and voxel-wise statistical comparisons were performed on the following: (i) patients at different disease stages and 2) patients who experienced the first demyelination attack without subclinical optic neuritis, assessed by visual evoked potentials. Standard parameters failed to discern any differences; however, voxel-based morphometry-optical coherence tomography successfully detected focal macular atrophy of retinal nerve fibre layer and ganglion cell/inner plexiform layer, along with thickening of inner nuclear layer in patients who experienced the first demyelination attack (disease duration = 4.2 months). Notably, the atrophy pattern of the ganglion cell/inner plexiform layer was comparable across disease phenotypes. In contrast, the retinal nerve fibre layer atrophy spread from the optic nerve head to the fovea as the disease evolved towards the progressive phase. Furthermore, for patients who experienced the first neurological episode, the severity of retinal nerve fibre layer atrophy at entry could predict a second attack. Our results demonstrate that voxel-based morphometry-optical coherence tomography exhibits greater sensitivity than standard parameters in detecting focal retinal atrophy, even at clinical presentation, in eyes with no history of optic neuritis and with normal latency of visual evoked potentials. Thinning of the ganglion cell/inner plexiform layer primarily concentrated in nasal perifovea in all disease phenotypes, indicating selective vulnerability of retinal ganglion cells and their perifoveal axons. Conversely, the degree of retinal nerve fibre layer thinning seems to be related to the clinical course of multiple sclerosis. The findings suggest bidirectional neurodegeneration in the visual pathway. Voxel-based morphometry-optical coherence tomography shows potential as a valuable tool for monitoring neurodegeneration on a patient level and evaluating the efficacy of novel neuroprotective treatments.

    Abstract Understanding the mechanisms underlying progression and developing new treatments for progressive multiple sclerosis (PMS) are among the major challenges in the field of central nervous system (CNS) demyelinating diseases. Over the last 10 years, also because of some technological advances, the visual pathways have emerged as a useful platform to study the processes of demyelination/remyelination and their relationship with axonal degeneration/protection. The wider availability and technological advances in optical coherence tomography (OCT) have allowed to add information on structural neuroretinal changes, in addition to functional information provided by visual evoked potentials (VEPs). The present review will address the role of the visual pathway as a platform to assess functional and structural damage in MS, focusing in particular on the role of VEPs and OCT, alone or in combination, in the prognosis and monitoring of PMS.
