Hello AnaMaria, if you are talking to me, yes, I am definitely maintaining my improvements. I had secondary progressive disease of about three years duration and I had had MS as a whole for about eighteen years then.
You could learn more about this by reading the following site: http://www.davidwheldon.co.uk/ms-treatment.html
Here you will find both information and links to papers, which aren't many since neurologists are by and large still welded to the autoimmune idea, in fact the only neurologist who I know is willing to treat in this way is Ram Sriram from Vanderbilt. I was treated by the above David Wheldon, my husband, who is an FRCPath in Microbiology.
