Reply to comment by userbrn1 in New Alzheimer’s drug slows mental decline by 27% in clinical trial by Shelfrock77

>We've always known (for several decades at least I believe) that amyloid proteins contribute to Alzheimer

From what I understand, what we've always known is currently being called into question.

  1. A lot of the research was faked.

  2. The drug Aduhelm reduces beta-amyloid plaques in the brains of people with Alzheimer's disease but does not improve cognition nor slow progression. Which also calls into question the amyloid hypothesis.

This drug in the OP also works on AB-amyloid and does appear to slow mental decline, but it allegedly does so by inturrupting the formation of new AB-amyloid by binding its precursors rather than trying to reduce already existing amyloid plaques. If these results hold then it further strengthens the amyloid theory.

I think that first article you posted exaggerates the degree to which the research was faked; independent biochemical testing was performed by more than just the scientists in question in the article and the amyloid theory continues to prove fruitful
