I have a concern that was expressed to me by my specialist. She says that there is a point where the carbodopa levodopa will not work (~10 years). I have been on the quick release and extended release for about 2 years and am concerned that if there is not a "new" drug or treatment found, Parkinson patients on this therapy will be in trouble. My physician for Parkinson's is well known in the state for both her work at the University of New Mexico and DBS treatment therapies. Has anyone else heard of this time limit placed on CD/LD therapies?
