Honestly, I have no clue on what a MS coma is. I have looked up MS for years, but never heard of that. I think that because the MS has progressed so bad in her that she couldn't communicate anymore. I also read that her eyes were responsive and knew what was going on.
It kind of makes sense because if she was in a regular coma, her family would have let her die years ago. She is tough and I hope she will will be remembered for that. RIP
