Quote from the article above:
While there's no cure for Parkinson's, a variety of drugs including L-Dopa (Levodopa) and Sinemet (Carbidopa) can slow its progression and help manage symptoms. L-Dopa is converted to dopamine in the brain. Sinemet prevents L-Dopa from being broken down before it reaches the brain.
There is no "mainstream medical" cure, and there never will be, however there are alternative cures, even for Parkinson's, which consists of chelation of heavy metals from the brain, as well as major diet changes, as well as supplements such as alpha lipoic acid and flooding the body with nutrients from organic foods.
