My dad was diagnosed with dementia almost a year ago and things have been going up and down since the diagnosis. One thing that has really stuck out is that dad really has no filter anymore. He literally says whatever he wants and doesn't care who it's towards or what he says...even if the comments are hurtful and inappropriate. He is really hateful towards my aunt, who has a lot of health problems, and makes hurtful comments about her health. He even talks about sex and I have never heard my dad talk about sex in my entire life. I've never seen him act like this or hear him make rude comments. I can't tell if it's just old age (he's 79) where he doesn't care what other people think or if it's the dementia. I realize that there isn't a lot to do because we never know when he's going to say something, but I can tell it hurts my mom so bad when he does make these rude and inappropriate comments. I just didn't know if someone has experienced this before.
