Trying to figure out what's going on with my Mom. Possible vascular dementia or something else?

Hey all,

My mom (62) had a bilateral, hemorrhagic, basal ganglia stroke about six months ago.

Her recovery has been amazing in a lot of ways. We had doctors literally tell us she wouldn't make a meaningful recovery and suggested to "let nature take it's course". While she only has movement/feeling on one side, she can kick a ball, push herself up in the PT gym, and seems to be doing better everyday. She's also speaking (some aphasia, volume issues) but we can understand her better every day.

So on the one hand she seems pretty with it. She knows everyone's name and recognizes everyone, including my daughter who was only two months old when my Mom had the stroke.

She watches CNBC all day, and was talking to me about AI and how her business could use it to reach customers (Her and my dad have a few retail stores).

I'd say about 99% of the stuff she says (that we can understand) indicates she is mentally "there".

But she's done this thing where she get's worried about these random things. She will say something like "Can you call the airline and cancel my flight?". There is no flight.

Or another one, "Can you go get X for me upstairs?". She's at a rehab center but the way she's talking about it, I think she's asking me to run upstairs right now and get her something.

I mean I'm sure that if I had the amount of damage done to my brain as she has, I might get a little confused now and then. But is it something that might be progressive? Something that I need to hound the doctors about evaluating?

I'm hoping she will keep improving, as she's already greatly defied the odds (her stroke type is VERY rare supposedly)...Google isn't much help about this so I'm curious if anyone here has any experience with instances like this?
