I am new here also, and was diagnosed a little over a week ago, so like you I am looking for information and answers pertaining to SPS. I also have demyelination disease and a cognitive disorder that the Dr says is like Alzheimer's but isn't Alzheimer's. I have only found this out recently and probably wouldn't have found out if it hadn't been for the atrophy of left leg. I also have anxiety which from what I understand is pretty common with SPS. I hope you find the answers you are looking for.
Good luck.
