We performed an online survey to assess lockdown impact in 176 patients with multiple sclerosis (PwMS) in the north of France. Access to healthcare was reduced for 38% of PwMS, mainly in physiotherapy, general practitioners and neurologists. 49.2% have implemented self-rehabilitation programs. Medical support was maintained for 39.2% through teleconsultations. 76.2% reported a negative impact of lockdown related to worsen disability. 45.5% expressed beneficial effects like strengthening family relationships, and reduced fatigue. Previous studies have found the same results on disability and discontinuation of care. However, even if this period has been challenging for PwMS, most of them have shown excellent adaptability.
