Very randomly, my mother asked me if i'd heard of this chemical; apparently in her Parkinsons (or brain science?) magazine, she was reading about trials which are beggining to show that in some individuals, testing created a mild Parkinsons-like effect. I don't really know what to make of this, I want to read the article though. I don't know how well known these effects are...?
Bit dodgy rushing into using some of these "newer" chemicals, better safe than sorry, tbh. If the studies she was talking about are accurate though, it could be quite useful in helping to understand Parkinsons, and possibly develop better treatment/a "cure", which is cool cool...
