Regular readers know that multiple sclerosis is a subject of personal interest to me, and that I occasionally pass along news on the science of that disease, included research into its causes, which are as yet undetermined. Well, there are, possibly, significant new developments on that front.
"Is there a geographical correlation with MS?"
Yes. Very strong. Here in NZ we have recently concluded a study where we believe we have found 96% of all people with MS and have a high percentage of returns and interviews.
These show that the rate of MS is 50/100,000 in the North of the country (closest to the equator) compared to 150/100,000 in the far South (nearest to Antactica).
We have a full workup of ethnicity as well, so Europeans might have a general 80/100,000, Asians 8/100,000 and Maori and pacific Islanders 2/100,000.
You never know, we might find some corelationship between the groups and the stenosis.
I do not have the data at my fingertips, but Scandinavians have high rates as well, including Scandinavian-Americans. Of course, most Americans who are all or mostly Scandinavian live in Wisconsin, Minnesota, and the Dakotas, also very northern.
This is very interesting information and also led me to information on inclined bed therapy. I was very recently diagnosed with MS and no doctor has ever mentioned inclined sleeping. It's certainly worth a try, especially since this study suggests that circulation could be closely related to the cause.
