Yes! My mom was the same. There was a lack of focus and it seemed like she was also trying to figure something out or what was going on. Very noticeable in photos too. I can tell if she is with it by looking at her eyes.

Talk about timing! A few days ago, I drove my husband to where we used to live (3 hours one-way) for a lunch with all the guys who used to play racquetball with him. A few family members also showed up. Of course, lots of pictures were taken and that kind of vacant look in my husband's eyes (and in the eyes of one of his old friends who was sitting next to him, which makes me wonder if he's having trouble) was so obvious compared to the others in the picture. I'd never really been consciously aware of that before seeing it in a picture in comparison with others.

@trishaanderson I saw this dementia “mask face” as they call it, episodically years before we knew my husband was having silent strokes. Now after 7 strokes, including 2 bilateral last week, he has the blunted flat affect, apathy, disengagement, and void look, like nobody’s home, much more first thing in the morning and then later now with some sundowning. He has Vascular Parkinsonism. Like others mentioned, had always been meticulous with self care and extremely neat, so leaving drawers, closets open and the toilet seat up were clear signs as his short-term memory has declined. Always a math wiz and suddenly couldn’t figure a tip. His morning shave and evening shower started taking twice as long, and with these 2 strokes, he can’t do self-care, remember how to use his phone, other tasks. Looks at light switches like he has some sense of an old habit then leaves it on. Now becomes glass eyed and anxious as the sun goes down, afraid of the dark, childlike. He was a 3rd degree black belt, instrument rated pilot, and computer wizard. So tragically sad.
