What is the Atlas of MS?

The Atlas of MS is the most comprehensive worldwide study of the epidemiology of MS and the global availability and accessibility of resources for people with MS.

Powerful tool for change

The information in the Atlas of MS can be a powerful advocacy tool, shining a spotlight on MS and raising awareness of the lack of adequate resources available to diagnose, inform, treat, rehabilitate and support people with MS worldwide.

Worldwide collaboration

The Atlas of MS relies on data supplied by MS organisations from around the world. We are most grateful to the country coordinators and their colleagues for taking the time and effort to gather the information and data.

The Atlas of MS is one of the strongest examples of what the global MS movement can achieve through collaboration. By bringing together evidence from countries around the world, it helps inform policy, strengthen advocacy and guide future investment in research and healthcare. The Atlas also highlights the need for continued investment in surveillance, registries and data systems to strengthen our understanding of the true burden of MS. Better data lead to better decisions and, ultimately, better outcomes for people affected by MS worldwide.
