Hey Rhayden, well could be MS, but could be some other sort of neurological disorder too.
Nope, MS doesn't kill people, people almost never die from MS. Once in a very great while, MS causes other problems that can make a person very sick or even die. But this does not happen very often.
There is nothing yet that can cure MS. But there are treatments which can reduce the number of flare-ups.
This means that your Mum may not have flare-ups so often. These treatments are given by an injection which is usually done at home before bedtime.
Other treatments could be pills which help with the symptons of MS, or doing special exercises to help improve walking.
It is important to remember that not all people with MS are able to make use of these treatments.

What does her doctor say? Does she ever have seizures? Sometimes even they are quiet and it looks like a person is asleep.
