"Bear, is it fair to say that this is the first statistically significant REVERSAL of dementia in any such trial, even if the sample size and time elapsed may be too small?"
I don't have the background to answer this. However, Jonzobot posted some related info recently in the post below. I'm not sure if those drugs/results are vs. placebo or vs. baseline though, so not sure if they achieved reversal. Maybe someone with more knowledge in this area can chime in.
