Increasing prevalence and incidence of multiple sclerosis in South East Wales

Abstract

Recent change in disease incidence and prevalence in this population is likely to be the result of environmental factors that have been operative in the past few decades in women alone and infers avoidable risk factors. Modelling of current overall incidence suggests a further increase in prevalence to 260 per 100 000 population within the next 20-40 years. Further studies are needed in order to identify recent changes in sex specific environment and lifestyle that confer susceptibility.
