Mum was a bit croaky over the phone this weekend, so we decided that I should visit next week instead. So here's something I turned up whilst trying to clear my 'Mum' in-tray. I picked it up from her apartment last time I was down there. It's a letter that was sent to her last year to inform her of an appointment for a scan.
As you can see, it's heavily annotated by Mum, mostly with the same two phone numbers over and over. From my experiences with Mum, I'd say that she kept finding this letter on her dining table, getting concerned about the arrangements and ringing the number at the top of the page. They would have given her the correct number to call (already shown at the bottom of the letter), which she noted down before ringing. Mum's written down the number 12 times on this piece of paper alone, but I'll bet there were other places she wrote these numbers. She could have been doing this at an interval of about 5 minutes or over the course of a week.
I do recall an occasion last year where a scan was brought forward suddenly - I wonder if they just got tired of her ringing?
Just a glimpse into the mind of someone falling into dementia.
