What's the present mortality rate of multiple sclerosi. are there surgical options for multiple sclerosis?

Two questions: 1. There is no surgical process that will beneficially help ms, other than possibly deep brain stimulation to control cerebellar tremors. 2. If treated with a potent medication, the lifespan should be similar to a patient without ms. 3. Forget this business with surgery to veins draining from the brain, it is life-threatening and does not work.
