My 82-year-old mom is really pretty remarkable, but not what she used to be — of course. She seems to be able to manage her own affairs (with the occasional assist), her health is good with the exception of an irritating hammertoe, and she just moved from her large house to a condominium complex which is not assisted living, but is populated by primarily folks 60ish and up. So, all in all, I consider myself very lucky.
I have noticed that she’s not as mentally quick as she was (to be expected), and she tends to repeat stories. She’s a bit of a compulsive talker, so it may partially be just filling dead air. The thing that’s more concerning to me is she is more subject to being influenced by others than she used to be; she’s generally quite opinionated, so that seems odd. She’s also needier than she was; calls several times a day, that sort of thing.
I live nearby, and try to keep an eye on her, but what I’m wondering about is how you can tell what’s normal brain aging and what’s the onset of dementia. I don’t think we’re there yet, but I’m hoping to get some ideas about what to watch for.
