Wow, I’m sorry you are having such a rough time and had to be hospitalized again! From what I’ve heard, neuropsychological testing can help determine what cognitive issues you are having. After the assessment, you can sometimes learn some strategies or get on medication to help with these issues. There are members on this board who are on tysabri, and probably some who have had first-hand experience with the neuropsych testing. Hopefully they will be along and will be able to give you better feedback than I. I just wanted to say hang in there with all that stress.
Please do come back and give us another update. I hope the steroids ease this flare for you quickly.
Here is a link with some info on neuropsych testing:
