Background Stress is a potential trigger for clinical and radiological activity in Multiple Sclerosis (MS). COVID-19 pandemic has been a relevant source of mental distress in people with MS (pwMS) and deeply impacted on disease management. Objective To investigate the association between stress, anxiety, depression, and risk of relapse during the COVID-19 pandemic. Methods From an electronic database used for clinical practice, we extracted data of relapsing–remitting (RR) or relapsing-progressive (RP) MS patients and calculated the annualized relapse rate (ARR) during 2019 and 2020. From 01/12/2020 to 30/12/2020, enrolled patients were invited to fill in a Google Forms survey to investigate depression, anxiety, stress, and Post-Traumatic Stress Disorder (PTSD). Results We selected 216 patients with RR or RP-MS to calculate ARR: compared to 2019, in 2020 there was a significant increase in ARR (p = 0.0142). Over 216 selected pwMS, 154 completed the survey. Matching the survey responses and incidence of relapses in 2020, there was a significant association between relapses and stress (p = 0.030 ) and relapses and depression (p = 0.011 ) , but not between relapses and anxiety (p = 0.130) or PTSD (p = 0.279). Conclusions Our results support the hypothesis that pandemic-related stress is associated to clinical exacerbations, both as a possible consequence of the COVID-19 impact on MS care.
