> This is false. They slow down disease progression by about 30%, as measured by cognitive outcomes. This is discussed in the article.

Perhaps I am just not well-informed but 30% slowdown in progression translates to sufferers have some mild improvement in cognitive tests and live a few months longer.

Maybe it is simply too early to tell but I would naively expect something much more significant. Perhaps this is the sort of thing that requires much earlier treatment to demonstrate better results.

I'm not saying amyloid beta research should be terminated. Merely that everyone in the field should be willing to entertain other ideas.
