Worried about confusing message off my mum

[Couldeataburgerrightnow]

She is 73, generally always been a bit ditzy, but noticed it getting a bit worse since she turned 70.
I live overseas and my parents are coming to visit. At the start of April, she sent me a Whatsapp saying they’d booked the flights and sending me the dates and arrival & departure times. We had a little chat, said how we couldn’t wait and all was good. We’ve communicated a fair amount since then, wishing Happy Easter and me checking up on her eye after an operation.

Today she sent me a Whatsapp message asking how I am and saying they’ve booked the flights and putting the times and dates (exactly the same as before) I sent a message back asking if these were the same times as i’m sure she already sent them and said they’d already booked. She said no they only just booked the flights yesterday.
I scrolled back through our posts and took a screenshot and sent to her. She sent a message back saying ‘Whoops we booked flights on 31st March and sent them to you on April 2nd’
I asked why she said they booked yesterday (I asked all this nicely and gently) and she replied ‘Because I couldn’t remember the day’ 🙄
I then made light of it, called her silly and moved onto something else.

Does this sound concerning? I don’t understand how she could have made this mix up, feeling worried

My mum also uses "recently" to mean any time from my childhood (80s/90s) up till yesterday! I don't think there's any point dwelling on it until you see her. She probably just forgot and tried to blag it.

That does sound a bit odd OP.

Are you worried that she forgot that she had already told you?

Or worried that they actually forgot that they had booked at all, and have now booked another set of tickets on the same flight?

Worried that she forgot she told me, but also that she seems to think they booked it yesterday or at least that’s what she said…and it was weeks ago

I can understand you feeling a bit concerned about this OP. How long are they coming to stay with you? I would wait and see how she is when you can spend some time with her. You can also ask your dad if he's noticed any forgetfulness in your mum lately.

My MIL had dementia and lived abroad, it was hard to gauge how she was from phone calls as she was quite hard of hearing. But when she came to stay for 3 weeks it became obvious fairly quickly that her memory was failing 😔
