Alzheimer’s can be caused by an undiagnosed bladder infection. Surprise! No money in that!!

It should be noted that amyloid plaques (comprised of AB proteins) remain a well-established and highly-replicated symptom of Alzheimer's onset and progression, along with aggregates of another protein, Tau.

This study, that was retracted, concerns a very specific form of AB termed AB*56 (as the molecular weight of this form is 56 kDa). The "magic" of 56 is that it is soluble and (according to the authors) precedes other AB aggregates, and therefore may be causal versus symptomatic.

Also relevant but not directly related is the ridiculous approval by the FDA of Biogen's antibody therapy targeting AB. The data was so bad that the entire advisory committee voted not to approve, and the FDA did so anyway, leading three advisory members to resign.

House of cards, indeed.
