Well, There Is A Bit of "Evidence"
Thanks for posting these published articles telling of the science of Anavex. In fact, there are others, too.
As with other Anavex investors, the papers you listed provide sufficient evidence for a moderate AVXL position.
Of course, those who find these many studies to be inadequate should invest their discretionary dollars in US treasuries. A sure and certain (albeit small) return. Not risky, like Anavex.
For some, you just can't be too risky with hard-earned dollars. AVXL is certainly not for the risk-averse.
