I agree you need to find a support group for the spouses of people with MS or whatever they decide your wife has. Check at one of the hospitals that is connected to a university. The support group will give you a place to talk to other people going thru the same thing. This way too, you can compare notes on doctors, staff, etc.
Also, find a support group that can help you with respite care where one weekend every few months, someone will care for your wife while you go fish or something to relax or you will be laid up and unable to advocate for her. My husband volunteers at an Adult Day care for people with Alzheimeirs or other problems with the brain. This gives the family members 4 hours a day to do other things, they are cared for and entertained, play dominos, etc. Once a month on the weekends, they will have 3 of the clients stay over from Friday evening to Sunday.
Zale Lipshy University Hospital is next door to Parkland Hospital in Dallas and connected to UT Health Sciences. Zale Lipshy specializes on problems with the brain. My husband had a large sub frontal brain tumor that was successfully removed in 2002. Thank heavens it was benign. He became a day client at the treatment center from July to December 2002, where they decided he didn't need to be a client but has worked as a volunteer.
Hope you find better treatment for her, although you may need to go to another state.
