that's the hazard of drug trials:  you never know if you're going
to get the placebo, because in double blind trials there's always
someone who will.

I don't have anyone in an Alzemed trial, so can't help you
with that one.  It may be that your mom got the placebo, or
that she got the drug, but it did her no good.  It is a sad but
true fact that most drugs that look good in mice turn out not
to be nearly as good in humans as the developers hoped.

How long ago did she enter the trial?  How long will it last?
How soon will you find out whether she had the drug or the
placebo?

In some clinical trials, if the drug proves itself, it will be
offered to the people who got the placebo at the end of
the trial.  If that is so for this trial, and if the drug proves
out, then your mom will be significantly better off for
having been in the trial than if she had not been in the
trial - since the drug may not be available to the public
at large for a long time.  Does this trial have a provision
like that?

I suggest you ask all these questions of the trial coordinator.

If you do, please let us know the answers.  If you don't ask,
I'd be curious to know why.
