Hi and welcome, I'm glad you are looking for answers for your mum. Diagnosing MS can be very frustrating because there are so many diseases that mimic the symptoms of MS. There still is no one test that gives a definitive answer to diagnosing MS.
Three weeks in the hospital is quite the stretch - has she been back to her doctor yet since discharge? I would start there with the questions about the tests andwhat needs to be done next.
Good luck, and I hope we see you a-round with more questions.

The hospital assessed her walking upstairs before she came home.....she managed 4 before her legs started shaking
