It's necessary that RRMS turns into SPMS and Does MS always cause paralysis?
This is a really excellent question. I think one of the first things people who have been newly diagnosed with Multiple Sclerosis ask is "Will I be paralyzed?" or "How long before I will need a wheelchair?"
The answer is...you might not ever need a wheelchair.
I am going to give you some information I have found which is very hopeful.
First of all The Grodno MS Clinical Research Centre says that: "Seventy-five percent (75%) of MS patients never use a wheelchair in their lifetime."
And this medical web site confirms this statistic:
"Recent studies indicate that 90% of patients with minimal disability 5 years after onset were still ambulatory at 15 years. Management of MS has changed dramatically. More than two thirds of those with MS are still walking 20 years after developing the disease. Forty percent of persons diagnosed with MS experience little or no disruptions of normal activities and 75% never need a wheelchair."
Now about whether or not patients with Relapsing Remitting MS will progress to Secondary Progressive MS, Connie Brichford writes about the different types of MS and provides this statistic: "Relapsing-remitting patients often develop secondary-progressive multiple sclerosis somewhere between 10 and 15 years after their initial diagnosis of relapsing-remitting multiple sclerosis, says Dr. Chitnis."
But listen to this. On PDR Health the author gives these stats: "Approximately 15% of all patients will only have a single attack of MS, and then never have symptoms again. In addition, some people have MS that will follow a relapsing-remitting course, but their symptoms will not progress. In fact, symptoms do not progress during the first 10 years of diagnosis in 50% of patients with relapsing-remitting disease.
The second course, which is called secondary progressive MS, also follows a pattern of relapse and remission, but symptoms get worse with each relapse. Thirty to fifty percent of patients with relapsing-remitting MS will eventually develop secondary progressive MS."
I am sure if you peruse the literature...you are going to find a variety of statistics. Yet I believe there is much reason for hope. It does seem that many people who are diagnosed with MS will not end up paralyzed.
I hope this helps some. Please let us know if you have any other questions.
