I am 56 years old and about a year and a half ago I went to a neurologist to find the cause of a slight tremor in my right arm and leg. I suspected I had PD and the doctor confirmed it. He recommended taking Sentimet but I had read where it loses its effectiveness over the years. For this reason I told the doctor I preferred not to take any medication until I could not continue doing things I enjoy,such as tennis and golf. I haven't seen the doctor since my initial visit. The tremors are slightly worse but still are not a problem. Lately though I've been wondering if there are any advantages to taking the medication. Could taking medication slow the process down,for example? Thanks for any information you may have. Jerry Taylor [log in to unmask]
