aamc fl5 ps q26

The results of the Study 1 and(or) Study 2 suggest that patients with AD show:

  1. A.significant structural loss of brain cells that can be prevented by pharmacological treatment.
  2. B.structural loss due to atrophy, but reorganization may preserve functional activity in some brain regions.
  3. C.functional loss in memory and structural loss due to atrophy that can be reversed through pharmacological treatment.
  4. D.functional loss in motor skills required for daily living without significant structural loss due to atrophy.

the answer here is B and I did get it right but I did not have solid reasoning behind it and I was very torn between B and C but ended up with B luckily it was the right one. If anyone knows how to explain how to get to B it would be great, thanks!
