Was the neurologist an MS specialist? If not you need to see a specialist for any chance at a diagnosis. It could be MS but it could be something completely different too.
An MRI with contrast and a spinal tap are "good" starts but there are more tests that need to be lined up including an evoke potential test and an EMG (Nerve conduction test). Sometimes getting an MS diagnosis is ruling out other things.
Now you've had space and time between two incidents which can also facilitate a diagnosis.
My DH had a general neuro who did all the right tests and yet still told us he didn't know and pushed us out the door. We took our paperwork an hour and a half away to one of the leading MS specialists. She took one look at the information and said it was obvious it was MS and diagnosed him THAT DAY. Then there was setting up medications etc which can take awhile. The sooner a person starts one of the DMDs (disease modifying drugs) the better for the long term prognosis.
When will the adoption be final? As soon as it is I would be pushing HARD to find out what the problem is because something is obviously not right.
