Orkney continues to top the table for rates of multiple sclerosis in Scotland, a study has revealed.

Tayside has the highest incidence of the disease in mainland Scotland, while the central belt and Borders have the lowest rates of MS.

The findings provide the first detailed snapshot of people affected by the disease across the country.

They are from the Scottish Multiple Sclerosis Register – a national database with records of people diagnosed since 2010.

The study confirms that Scotland has one of the highest rates of MS diagnosis in the world. It reveals that incidence of the disease varies substantially between regions but as yet can’t pinpoint the exact reasons why.

Rates of diagnosis were three times higher in Orkney than the central belt and Borders, researchers found.

Women are particularly susceptible, with rates of the disease double that of men.

For example, a woman in Orkney has a one in 50 chance of developing MS compared with around one in 600 for a man living in the Borders. The study adds weight to previous findings that disease rates are greater in northern regions but suggests that other factors may also be important. Figures showed incidence of the disease in Shetland is more than one-third lower than in Orkney, despite Shetland being located farther north.

Rates of MS in Tayside are almost double those in Lothian. Further studies are needed to probe the underlying causes of regional and gender differences, the team says.

The research was led by the Anne Rowling Regenerative Neurology Clinic at the University of Edinburgh.

It is published in the Journal of Neurology.

Dr Patrick Kearns, Rowling Scholars Training Fellow at the University of Edinburgh’s Centre for Clinical Brain Sciences, said: “The Scottish MS Register is a powerful new resource – the result of substantial far-sighted investment.

“It allows us to study, in detail, the geographic risk of developing MS. There is much more work to be done, not least to further ensure the accuracy and precision of the register. However, our hope is by understanding more precisely where the areas of higher and lower risk are found in Scotland, we can start to work out why.”

Morna Simpkins, director of MS Society Scotland, said: “More than 11,000 people in Scotland live with MS, which can be relentless, painful and disabling. Learning why rates vary so much between populations could help us understand more about what causes MS and, most importantly, how to stop it.”
