Everyone is entitled to his/her opiinion, but this is a fact.
The one drug we have depended on for 40 years is L-dopa (aka Sinemet). In spite of its side effects, it works. Had someone said what you just did 40 years ago, all PWP would be sitting in wheelchairs, drooling in the corner, and in a cataonic state.
If you don't want to be in a trial - that's your opinion, but please realize that SOMEONE has to test the drugs or treatments, or there will be no improvement in quality ofo life, nor will there ever be a cure.
Enough said. Hugs, Tena.
