It goes even further than that. since we don’t know what causes Alzheimer’s, what they’re doing is trying to cure their own laboratory-induced symptoms in mice. It’s like trying to fix a car’s ABS system by simulating tire slippage.

This is so obvious that the only thing I can think is that they simply don't care. They just want to find something that masks the symptoms (perhaps to keep patients dependent on the drug for life if they succeed).

What causes Alzheimer gentlemen? very few people is really trying to solve this answer.

Is it even known what causes the moments of lucidity in patients? Molecules should be mapped to identify the patterns (and therefore track possible sources).
