INTRODUCTION: Covid-19 has been sweeping over the world for more than a year. People with Multiple Sclerosis (MS) might be particularly vulnerable either for the disease iteself or for the ongoing immune treatment. The aim of this review is to understand the impact of the Covid-19 pandemic and lockdown on patients with MS and to provide evidence-based advice to ensure them a high standard of care even during the pandemic. AREAS COVERED: Literature search was conducted in the Scopus, Web of Science, Pubmed electronic databases, and articles reference lists to investigate the effect of Covid-19 on MS patients' treatment, access to health-care services and mental-health.The search terms 'multiple sclerosis' AND 'Covid-19' were combined with each of the following term 'disease modifying treatment,' 'steroids,' 'vaccination,' 'mental health,' 'stress,' 'quality of life,' 'management,' 'impact,' 'recommendations,'. EXPERT OPINION: To ensure MS control during the pandemic, minimizing the risk of Covid-19 contagion, face-to-face visits may be implemented with televisits. Management of relapses and DMTs schedule should be adapted based on the specific benefit/risk ratio for each patient, considering disease activity, disability, comorbidities. Vaccination should be strongly recommended. Telerehabilitation and online psychological support programs should be encouraged to preserve motor performances and mental health.
