I can't say that I think the data presented in the research noted here merits quite the degree of the attention that it has been given in the popular science press. It is interesting, but not compelling if its role is to be evidence for a lack of correlation between amyloid-β and cognitive decline. When thinking about the early stages of loss of cognitive function, in which changes are small and subtle, one might have to consider other factors such as vascular dysfunction or other neurodegenerative conditions with quite different mechanisms that could produce these effects. The interplay and relative importance of the field of mechanisms at this stage of aging is far from clear. Nonetheless, the present mood of the scientific community and its onlookers is that of a growing revolt against the amyloid cascade hypothesis of Alzheimer's disease, so research that ties into that mood receives attention.

There has been a longstanding belief among neuroscientists, backed by scientific evidence, that beta-amyloid, a protein that can clump together and form sticky plaque...
