Thank you for the links. I don't know for sure what he is on. He did say what he takes is a combination of two different drugs. I don't think he sees a PD specialist. We both see the same neurologist. I go because of migraines. He is also not undergoing any therapies. His speech has gotten worse over the last little while but he says he cannot afford the co pays for speech therapy. He has early onset PD. He is in his 50s and has had PD for quite awhile. Thanks for the suggestion to go to the dr together. I hadn't thought of that and since we see the same one, it should work well.
