My GAD antibody test came back about 10x normal. They use a combination of plasma exchange and IVIG to treat the actual disease and then I take Baclofen, Valium, and Neurontin to mask the symptoms. Hopefully they can get it under control. I went from using a walker to being able to move around on my own. My still have stiffness and pain, but my neuro is limiting the amount of meds I take so as not to make my Myasthenia worse, as I also have both diseases.
