it's lab mice. it's NAD+. i can't remember because i'm not an ad researcher, but there are 3 models of AD. one is NAD+, two aren't. Most of the research was going into NAD+ or another, and they discovered that that specific model was not going to help human patients. It did nothing to effect research or funding. that was about... 15 years ago? so forgive me if i don't get up.
