1. Survey background & disclaimer

Doing clinical trials of neuroprotective therapies in people with progressive MS has proven difficult. At present there are no licensed therapies for progressive MS (secondary and primary progressive disease). This survey is being done to see whether or not people with MS are prepared to have three lumbar punctures as part of a clinical trial to assess whether or not neuroprotective therapies work in MS.
