Morning Lymelink....you are the second person who recently mentioned the connection Lyme's Disease may have with any form of dementia! (Duncan1 also talked about this in the " is early onset always genetic?" thread.)
So often we believe Alzheimer's and other challenges to be blamed on hereditary or "chance" reasons...and don't think about other factors. I've read what you've posted in many articles and believe this can happen....one other supposed reason for dementia challenges I've read about is the presence of black mold causing similiar problems.
About 10 years ago, on a vacation in the Upper Peninsula here in Mi...I found myself scratching an itchy spot on the back of my neck...when my husband looked, there was that tell-tale red circle a few inches out from the pin-point bite! By the time we returned home, nothing was visable, but I still went to the Dr....she gave me a shot (can't remember what...bad sign with Alzheimer's in the family!) that was supposed to take care of the chances of Lymes Disease. We do have several families locally challenged by Lymes; there is even monthly awareness meetings.
Both you and Duncan have brought up an important issue that should not be ignored! After having Alzheimer's directly affect each of us who post here...if there is even a TINY chance that it can be reversed, it should be considered!
Thank you for your thoughtful post..........Pam
