Thanks for posting the link.

In my opinion, alpha-synuclein's key role in the etiology of PD is as good as proven, although the details remain:
- what causes the misfolding to start?
- when does an instance of misfolding become prion-like and "reproduce"?
- is a genetic predisposition to over express AS important?
- are rogue forms of AS communicable?

Clumping seems bad news, but in vitro tests [1] have shown that curcumin can reduce aggregation.
