Guest guest Posted February 15, 2006 Report Share Posted February 15, 2006 Forgot who, but a number of months ago someone (male) wanted to get stats of MS people and their location {using zip codes}. We talked about people moving from where they used to live to where they live now, where first symptoms started, etc. The bottom paragraph states that age 15 is the cutoff for moving. I don't know where they got this info, but it is interesting. S. Szpak http://www.nationmaster.com/encyclopedia/Sclerosis Prevalence In northern Europe, continental North America, and Australasia, about one of every 1000 citizens suffers from multiple sclerosis, whereas in the Arabian peninsula, Asia, and continental South America, the frequency is much lower. In Sub-Saharan Africa, MS is extremely rare. With important exceptions, there is a North-South gradient in the Northern hemisphere and a South-North gradient in the Southern hemisphere, with very low frequencies near the equator. Climate, diet, geomagnetism, toxins, sunlight, genetic factors, and infectious diseases have been discussed as possible reasons for these regional differences. It has been postulated that an environmental factor during childhood might play an important role for the development of MS later in life. This was based on several studies in migrants demonstrating that if migration occurs before the age of 15, the migrant acquires his new region's susceptibility to MS. If migration takes place after 15, the migrant keeps the susceptibility of his home country. Quote Link to comment Share on other sites More sharing options...
