Conclusion: National incidence and risk factor assessments may become a basis for the evaluation of prevention trials - prospects from the Third Nordic MS Symposium

Abstract

This symposium started with an overview of recent incidence and prevalence data from the Scandinavian national registers and continued with a critical analysis of several alleged risk factors for MS. These risk factors are constantly changing and therefore might explain current incidence changes. In addition, they may be the subject of preventive measures.
