unable to speak

First off I am typing this here because she has been diagnosed with Multiple Sclerosis. She's been having trouble remembering things and talking. Often she would stutter trying to find the word when talking to me on the phone. But now it's got so bad that she cant even speak anymore. You know that feeling you have when your in a conversation and you cant remember a word but it's on the tip of your tounge? Well it's like that for her now but with ever other word. My brother tries to hold a conversation with her and she gets so fustrated and starts to cry because she literally cannot remember the words and would often say words that make no sense. Does anyone know what to do in this type of situation? I'm in the military in Japan and my brother said that she's in the hospital and the doctors are giving her steroids but other than that they don't know what to do. It's so bad that she can't communicate with anyone. No one knows what she is trying to say now. She just turned 56 a week or so ago. Please help.
