Background: It is essential to investigate cognitive deficits in multiple sclerosis (MS) to develop evidence-based cognitive rehabilitation strategies. Here we refined cognitive decline assessment using the automated tests of the Cambridge Neuropsychological Test Automated Battery (CANTAB) and hierarchical cluster analysis.
Methods: We searched for groups of distinct cognitive profiles in 35 relapsing-remitting MS outpatients and 32 healthy controls. All individuals participated in an automated assessment (CANTAB) and in a pencil and paper general neuropsychological evaluation.
Results: Hierarchical cluster analysis of the CANTAB results revealed two distinct groups of patients based mainly on the Simple Reaction Time (RTI) and on the Mean Latency of Rapid Visual Processing (RVP). The general neuropsychological assessment did not show any statistically significant differences between the cluster groups. Compared to the healthy control group, all MS outpatients had lower scores for RTI, RVP, paired associate learning, and delayed matching to sample. We also analyzed the associations between CANTAB results and age, education, sex, pharmacological treatment, physical activity, employment status, and the Expanded Disability Status Scale (EDSS). Although limited by the small number of observations, our findings suggest a weak correlation between performance on the CANTAB and age, education, and EDSS scores.
Conclusions: We suggest that the use of selected large-scale automated visuospatial tests from the CANTAB in combination with multivariate statistical analyses may reveal subtle and earlier changes in information processing speed and cognition. This may expand our ability to define the limits between normal and impaired cognition in patients with Multiple Sclerosis.

SUMMARYInfection has long been hypothesized as the cause of multiple sclerosis (MS), and recent evidence for Epstein-Barr virus (EBV) as the trigger of MS is clear and compelling. This clarity contrasts with yet uncertain viral mechanisms and their relation to MS neuroinflammation and demyelination. As long as this disparity persists, it will invigorate virologists, molecular biologists, immunologists, and clinicians to ascertain how EBV potentiates MS onset, and possibly the disease's chronic activity and progression.

This study explores the integration of telerehabilitation, virtual reality, and serious games technologies in addressing physical disabilities. Specifically, it focuses on game-based telerehabilitation for patients with stroke, Parkinson's disease, and multiple sclerosis undergoing home-based rehabilitation. Utilising the PICO approach, a search in Scopus and PubMed until February 21st, 2024, identified 31 relevant English articles out of 258 initially considered.

Introduction: Multiple Sclerosis (MS) is a complex auto-inflammatory disease affecting the brain and spinal cord, which results in axonal de-myelination and symptoms including fatigue, pain, and difficulties with vision and mobility. The involvement of the immune system in the pathology of MS is well established, particularly the adaptive T cell response, and there has been a particular focus on the IL-17-producing subset of Th17 cells and their role in driving disease. However, the importance of innate immune cells has not been so well characterised.

The sphingosine-1-phosphate-5 (S1P) receptor is one of the five membrane G protein-coupled receptors that are activated by the lysophospholipid, sphingosine-1-phosphate, resulting in regulation of many cellular processes. S1P receptors are located on oligodendrocytes and are proposed to influence oligodendrocyte physiology. Understanding S1P modulation during processes such as remyelination could have potential applications for demyelinating CNS disorders such as multiple sclerosis (MS).

Marburg disease (malignant multiple sclerosis, MS) is a rare, acute MS variant, predominantly occurring among young adults. Because it is characterized by rarity, high morbidity and mortality rates, the disease needs to be further characterized, and the experience of the physicians play a role in treatment regimens. We report the case of a 15-years-old female presenting with progressive weakness over the limbs, hyperreflexia and loss of sensation by physical examination, lab tests and radiological investigations (MRI).
