Try the anti-inflammatory diet. That's what my neuro recommended and I'm doing OK.
What are her symptoms?
For a neuro to say that she will get worse is terrible. Of all people h/she would know that MS is an unpreditable disease of he CNS .. keyword unpreditable.
I used a cane for a while and just like that...haven't really required it since. It's not to say that at some point in time that this will change, either temp or perm...
Is your mom Relapsing Remitting, Primary Progessive or Secondary Progressive...the latter two will get progressively get worse but if she is on a disease modification drug...should slow it down.
Does she take any injections?
