Tremors of both kinds?

I'm 43 years old and was diagnosed with Parkinson's Disease in April of '05.  I had previously been diagnosed with Essential Tremors but 1 1/2 years later the same Neurologist changed the diagnosis to P.D.  I am still experiencing the tremors with movement as well as a little of the resting tremors.  From everything I've found in researching both diseases a patient has one or the other, not both kind of tremors.  Does anyone know anything new about this?  I told my Neurologist about it and he pretty much blew it off.

Yes, you're right...I didn't get too much into my treatment plan and other symptoms. I don't have writing problems. My speech will get kind of hoarse sounding at times. When I walk, my left foot will roll toward the outside edge & no real balance issues. My chiropractor & massge therapist have helped with the walking issue. My neurolgist put me on Mirapex and I am currently taking .5 mg 3 times/day. It has made some of the symptoms go away but I still have tremors when I move and have still been taking Endural (.5 mg/1 time per day) for them ever since I was originally diagnosed with "Essential Tremors.

So you're saying that it IS normal to have both kinds of tremors? I am actually thinking about switching neurologists because I am going to be involved in a Parkinson's Study coming up in July. The neurologist conducting the study specializes in Parkinson's Disease.
