Brian, Yen and others, Under the microscope there is no apparent brain damage from sinemet. Nonetheless, I would assume there are some brain changes at the receptor sites at least on the molecular level since long term sinemet induces dyskinesia. Therefore it would be assumed that it induces a change which might be classified as brain damage. From the practical standpoint Yen these days PWP usually start off taking a dopamine agonist such as mirapex (pramipexole), bromocryptine or pergolide to start starting sinemet only if the agonist doesn't relieve symptoms thereby delaying the use of and then hopefully the dyskinesia which is induced by sinemet.
