The major problem has been lock-in of the Abeta 42 peptide fragment as the cause. This monomaniacal focus was rewarded by grant awards to team players.
Karl Herrup has a terrific book on the topic How Not to Study a Disease — The Story of Alzheimer’s from MIT Press (2021, ISBN 9780262045902). He did not win many friends but I think he is right.
The consensus now is that many factors contribute to the heterogeneous diseases we now call Alzheimer’s.
The article (or I guess more accurately "podcast transcription") seems to be saying that this lock-in essentially happened due to fraud, since some of the data was intentionally doctored to get the intended result. One of the guests seems to be an author of a different book about this (with the other guest being the scientist who apparently uncovered this). I can't personally attest to the accuracy of anything they said, but they're at least alleging that it was a lot less benign than it sounds like you're describing.
The focus is definitely on scientific fraud, but what makes the fraud so easy in this case is singing and selling the same song that the big teams are singing and selling. You can fly under the radar AND get funded, and if you are “lucky” become an ultra big shot like Masliah at NIA.
I don't buy the fraud explanation as the full explanation. Other areas of medicine (stem cell) has had bigger incidents of fraud on top of other major headwinds, and still has made more progress.
Fraud is everywhere and we still move forward in most arenas.

Reminds me of schizophrenia. A hodgepodge of different things lumped into a single label of "broad class of things we don't understand"
Some day autisim, neurodivergent and ADHD can join that illustrious list.
There’s another book mentioned in the podcast called “Doctored.” The gist is: bogus “science” led to loads of money / research going in a direction that was effectively fiction.
People love to praise “the science” when they mean the scientific method. What they always seem to forget is that method is executed by humans. Imperfect, sometimes ego driven humans.
