I sense that a couple of the study participants are jumping the gun to get some free publicity. The results are positive, but research is at a very early stage.
From the Vancouver Sun article: "While a pill version of the drug is possible and would also help prevent senior citizens' fading memories, it won't be ready for at least a few years — something Costa-Mattioli said would depend on securing funding and finding a lab willing to pick up where his research left off."
