It's hard to discern discourse in a field one is unfamiliar in, I'd tried with the Alzheimer's fiasco. Here's my tuppence:

The plaques are known to be linked to Alzheimer's, the debunking of one paper that messed with its figures does not detract from the whole body of research. The inefficacy of plaque-targeting treatments may not be proof that the plaques are not causal in nature, only that their damage is not reversible/fully understood.
