I'm a Chinese graduate student in Columbia University. My dad was diagnosed to have PD about 5 years ago, when he was 58 years old. He has been taking L-dopa,whose effect has been decreasing. He is trying a new drug called Parledol, which is a dopamine agonist. I'd like to know if it's more benificial to take these two together, or as I read on the Parkinson's Web, the combination has a negative effect.(increased mortality) I am also thinking about Pallidotomy for my father. However, since my dad is in China, and the surgey seems to be more mature in U.S. and some other countries, I'd like to know if there is any resource to help finance this kind of surgery in these countries. I don't know if ther is any kind of insurance which could at least partially cover the expenses, considering meself is only a visiting student holding a F-1 visa.Also if anyone knows any facilities that can perform this kind of surgery in China or other Asian countries which the cost of surgey may be lower, please let me know. Thanks. Tong
