> the fake Alzheimer's they induce ....

I used to work with a guy who had been a scientist at a large pharma company (we were both working at a small biotech start-up at the time).

He told me an interesting story... basically, scientists at his company would get an extra year-end bonus if they had worked on a drug candidate that made it past animal studies and into human (clinical) trials.

He told me that one way to 'consistently' get the extra bonus was to work on candidate drugs for neurological diseases (e.g., Alzheimer's, etc.) because ... the animal models for those diseases were (generally) dog shit, so it was easy to find a drug that 'cured' whatever happened to be your neurological disease of interest in mice/rats/etc.

Then you get your bonus and the drug fails in humans.

Lather, rinse, repeat.
