My mom's had some personality changes since coming down with dementia. For one, she doesn't attend church anymore. Church is really close by; with assistance she could walk or be driven there easily. She just doesn't want to go. She'd been a Catholic all her life, and was just suddenly tired of all that Catholic stuff, in a way I thought I'd never see her be.

My mom's personality changed a lot with dementia. After a couple of months she forgot she was a heavy smoker. Watching documentaries and sitcoms pre-dementia was replaced with aimless watch anything but not really caring about it at all. She lost a lot of self restraint so it was hard to go out to places because she'd make an insulting remark about a stranger. We tried anyway. This was all after she forgot who her children were so we were getting pretty late stage.
