Covid-19 may raise risk of developing multiple sclerosis

Covid-19 may be a risk factor for multiple sclerosis (MS). This has been shown by new research at örebro University and örebro University Hospital, Sweden.

We saw a raised risk of MS among people who had severe Covid-19. However, only an extremely small number of people who had severe Covid-19 received a subsequent MS diagnosis."

Scott Montgomery, professor in clinical epidemiology, Örebro University

Scott Montgomery examined the records of all patients with Covid-19 that were admitted to hospital in Sweden between 2020 and 2022.

The results showed that nearly 26 per 100,000 patients with serious Covid-19 subsequently developed MS. This was more than double the risk than in those without a Covid-19 diagnosis.
