During normal conversation, Mom is still remarkably articulate despite her other deficits. However, for years now, even before her Alz diagnosis, Mom has had episodes of random muttering. It often occurs after a conversation comes to a close; then she will walk away muttering unintelligible stuff. I can't make any sense of it but haven't drawn her attention to it because I don't want to embarrass her. It almost sounds like a continuation of our conversation, perhaps things she wanted to say but didn't, but I can't be sure. Is this a component of her dementia or just a quirk?
