And over here, with my husband's mom. We took her with us to Alaska in 2007. I had known him less than a year at that point, and only met her a couple of times as we lived several hours apart by highway. Although she seemed bright and with-it 95% of the time, there were odd lapses. For instance, she would be peeling potatoes for supper and put the paring knife down on the counter and couldn't find it a few minutes later. Same with her purse... twice she was very upset that she'd lost it, and it turned out to be sitting on her bedside table where she'd left it. A couple other times she got lost in small gift shops and couldn't find her way out, and seemed puzzled at the things in her basket. Since we were relatively new to each other, and I to her son, I hesitated to say something to him about my observations. In addition, his dad/her husband of 50+ yrs had passed the year before; we all know how depression can affect our cognition.
But that changed when we got home. She had driven to St. Louis and left her car at our house. She was frantic when it was time to drive back to Illinois, that she would get lost. She *knew* the darkness was closing in at times. We drew her a map (simple... she only had to switch highways once). She was still frightened, so we had her follow us in her car and guided her to the first highway. She vanished! We had no idea where she went; she had no cell phone either. It turned out that she went west instead of east.... by almost 50 miles, then suddenly the fog lifted and she reversed course and remembered how to get home. I told him of my earlier observations and that it might be time to alert the family to start keeping a closer eye on her.... she lived alone in the family farm house, but did babysit the close-by grandkids daily. They started noticing lapses too, including leaving the stove burners on. Eventually she entered a skilled nursing facility, in 2011. This dear soul passed last year.... 10 years after we noticed the decline.
If indeed Trump is in the early to mid-stages of dementia, his ppl are covering up for him. We can only hope for the sake of our country that they are decent and honorable ppl. Given his history of poor choices, though... frankly, I am terrified.
