i think this wasn't taken very seriously because your supporting articles are very weak.

this article was in a unknown blog by an unknown blogger. Plus he stated a lot of nonsense such as
"It should be noted that there really is a drug to fight the Parkinson’s. This drug, which goes by the commercial name of Levodopa, works by reducing the Dopamine level in the brain, thus helping the central nervous system coordinate more efficiently."

just my opinion.
