My great grandfather is deteriorating and I'm worried it is negatively impacting my family and I'm not sure what to do. - Lemmy.world

My great grandfather moved in with me as he is having a hard time living alone and his cognition is starting to fade he is incredibly rude and claims false things due to his lack of senses in his older age and has fallen multiple times. I am starting to see that this situation could get worse and I am not sure how to proceed. I am thinking it would be best to have him stay at a facility that is properly equipped to handle him though I fear the family backlash from such a situation may be seen as taboo. Is there anything I should do to properly handle this situation? Do I need specific documentation or anything? I’m new to this and not sure how to proceed he wasn’t always like this he was a good person when he was younger but I fear my kids may be negatively impacted from how he acts towards them now. Please help, thank you
