Re: Statins may delay effects of Alzheimer's: study

That is a slightly different test. Yours is, of course, is logical and
straightforward, and what the actual results might show.

However, the statin companies' marketing hype and spin claims that statins
affect the progression of Alzheimer's DISEASE, not quite the same as harmful
to the population.

My concern is that there is currently no study that uses a test to
distinguish the difference between cognitive damage due to statins and
cognitive damage due to Alzheimer's Disease. Since it is clearly documented
that both have negative cognitive effects, unless and until the damage can
be differentiated by cause, the results of such studies cannot claim to
indicate the influence on the progression of Alzheimer's DISEASE.

And that is exactly what they claim.
