I recall that people have been talking for a long time about a connection between MS and light. Getting enough light which is why prevalence rates seem to be higher in the higher latitudes. What I hadn’t realised is that they’d gone further than that:
Now the researchers are trying to work out why the rate in Orkney is so high. Last month, a study found evidence that vitamin D supplements for pregnant women in colder, darker countries could stave off multiple sclerosis in their unborn children.
The finding adds to a growing body of work showing a link between low vitamin D levels and the debilitating disease, in which the immune system attacks the body’s own nerve fibres. Dr Jim Wilson, from the Centre for Population Health Sciences at the University of Edinburgh, said: “Our study shows that Orkney has the highest prevalence rate of multiple sclerosis recorded worldwide.
For example, does Orkney actually have daylight at this time of year?
