Lorraine Hill, This is in response to your post about Dr.Simuni at Penn Hospital in Philadelphia. I was diagnosed last October with Parkinson's at the age of 45. For a second opinion, I went to the Parkinson's Movement Disorder Center in Philadelphia in December. My doctor was Dr. Tanya Simuni who you asked about. She gave me a thorough exam and confirmed the diagnosis of Parkinson's from the Neurologist that I had been to. She wanted me to be in a test study group to test Remacemide and talked about different meds she could start me on. I opted not to do anything at that time. I was scared and devastated by the confirmation and told her I needed more time to adjust to the news of Parkinson's. I've been following through with my Neurologist here in N.J. for the time being. I have been on Selegiline since January. I feel Dr. Sumuni was good and will probably go back to the center at a future date. I've read good things about the center and understand that Dr. Amy Colcher is an excellent Dr. at the center too. If I can help you in any way with more information you can e-mail me directly.
