The MS population is ageing [1]

 


 

In western countries, more than half of MS patients are now 45 years of age or older [2-4]. The rise in age seems to be mainly driven by declining mortality as the incidence of MS appears relatively stable [5]. A study from Bavaria, Germany exemplifies the trends in MS prevalence by age (see below) [2]. A recent population-based study in Norway also observed a steady increase in the age of MS onset [6]. Today, a quarter of patients may receive their diagnosis of MS at the age of 50 years or older [6].

 

Trends in MS prevalence and incidence in people living in Bavaria, Germany


 

In this study, health administrative data from more than 10 million people living in Bavaria, Germany, were analyzed [2]. From 2006 to 2015, the MS prevalence increased from 171 to 277 per 100,000, while incidence rates remained relatively stable (range 16-18 per 100,000). A substantial increase in prevalence was observed in those between 40 and 60 years of age. In 2015, 60% of the people with MS were at least 45 years of age or older [2].
