Presumably, a newer generation of anti-amyloid or anti tau agents. There are current gen ones (targeted monoclonal ab ) which aren’t that incredibly effective but there’s some thought that maybe that’s due to treating the wrong patients at the wrong time, vs starting therapy earlier on

Didn't it turn out that the amyloid plaque hypothesis was based on a fraudulent paper?

Not exactly. There are "issues" with one of the early papers, and I believe some other follow-up papers, but not all research had these issues.
