Thank you, Lyn and Graceann,
I have considered Lyme as the culprit. I posted here because I don't know all that much about Alzheimer and have been wondering. There are many conditions that mimic each other...
I have opened the door with her that maybe her "ADD" and fibromyalgia may be in fact Lyme and she seemed open to that idea. I know that neuroborreliosis (neurological Lyme) and Alzheimer have a lot in common.
I appreciate your concern and comments and ideas. I have been losing precious sleep over this, which I need because I myself am sick with Lyme.
