Audrey - I agree 100% with Greg, and would echo everything he says. I've watched people have to go on disability because some idiot doctor wants to withhold the meds in case they're needed more later. Medicate for today! In addition, Audrey, there are deep brain surgeries available in Australia as well as elsewhere in the world, should your friend eventually need it. And there's always a chance that a cure will come along before too many more years. Margie Swindler
