Does Dantrolene cause depression?

I have been thinking a lot about how to help my mother deal with her multiple sclerosis, but it seems that I can just give her my moral support and nothing else. She has to take her meds and that is it. The problem is, she is becoming more and more depressed and I wonder if it has to do anything with Dantrolene? Does this drug cause depression?

Honestly, I haven't found anything on Dantrolene and depression, except for the fact it must not be mixed with alcohol and depressants. There might be some connection, but I guess your mother does not drink or take anti depressants. Still, there are so many other dangerous side effects of this drug, such as liver damage after long use (I would put that on the first place).
