I agree that in order to properly diagnose PD, one should seek a specialist in movement disorders. I was diagnosed with PD in December of 1994. I followed up with a specialist in PD in NJ. He felt that there was a 75% chance that I did in fact have PD. I continued with the neurologist that initially diagnosed me with PD. To make a long story short, I treated for PD thru April of 1997. It was at that time that it was determined that I was misdiagnosed. This came from several new doctors that I saw in the beginning of 1997. One of the doctors was from the Parkinsons Institute in Sunnyvale, Ca. Essentially, I am trying to say that proper medical attention with a qualified physician in movement disorders is a must....
