What are the things you wish you'd done (or are glad you actually did) when you first thought things might be off, but before any diagnosis of dementia. Or maybe even before any specific suspicion?
Thankfully, I'm not in this position, but a friend thought the collective experience of this forum might give them some insight they haven't gotten from reading articles/websites on the topic of dementia. There are warning signs, but not significant disability yet, and no way to tell how fast things might progress.
