I think you are correct on that.

Exactly right I think.  The article says:

   "People with more years of formal education appear to have a
   greater "cognitive reserve," Hall said, referring to the
   brain's ability to keep working despite damage.

   "While better-educated people may be diagnosed with
   Alzheimer's later than people with less education, it appears
   they have suffered brain damage but their "cognitive reserve"
   was able to hide and delay the effects, the researchers said.

I remember hearing a lecture by Dr. Trey Sunderland, then
directory of the NIH National Institute on Aging.  He said he
couldn't see how education would have any effect on the physical
disease progression process, so he too thought it was the case
that more intelligent and educated people just held it together
longer in spite of the deficits.

He put it this way.  A highly intellectual person may have six
ways of thinking about a problem for which another person only
has two.  As they both begin to lose capacity, the intellectual
can keep functioning after he loses 1, 2, 3, etc. ways of
thinking whereas the other guy is out of luck after just two.
