Headline over rise in cases of MS misleading
IN response to your article headlined '50% rise in those living with MS' (News, October 2), I would like to correct some of the information included.
The MS International Federation's Atlas of MS 2013 looked at the number of people living with MS around the world. It's compiled through surveying experts across the world and brings together the best available evidence.
The MSIF has used figures for the Atlas of MS 2013 which state the prevalence of MS in the UK is 164 per 100,000 people.
However, this figure is considerably higher than the figure used in the previous (2008) edition of the Atlas, which was 110 per 100,000 people. This 2008 figure was based on the very limited evidence available at the time.
The prevalence of MS may have changed slightly between 2002 and 2009, but the major difference between these two studies is due to the improved methodology, rather any dramatic increase.
Our research estimates that in Northern Ireland approximately 3,000 people (1 in 500) are affected by the condition.
