tradeherpete....great response to my question and I concur 100%--I'm glad you mentioned the piano player and the artist--those reports on how they have regained lost skills after taking 2-73 seem not to be significant by most on this board.I think those reports are mind-boggleing especially emphasizing what Dr. MacFarlene discussed re: mood-quality of life-joy with being able to participate in life.Test scores on paper are one thing but how do you put a number on happiness-self-satisfaction-everyday mood improvement---PRICELESS---I truly believe Anavex is "quality merchandise" and hope one day all will recognize it as such. Thanks for shareing your experiences with your mom !!! Best of luck to you !
