I help my mother-in-law (age 83) care for my father-in-law (age 84). He has been diagnosed with acute dementia from a blood sugar drop back in 7/2019. He improved from where he started but seems to be at his baseline now. My mother-in-law is constantly telling him to "sit down, be quiet, stop it, don't do that, you ARE home, etc. At first she would get very angry and argue with him. She has calmed down some but still very much trying to direct what he is "allowed" to do. All of us kids (their son and daughters) are more frustrated with her and her management of him than we are with his dementia. She is NEVER alone with him. Someone is with them 24/7. She wants us there to help her with him, but is sporadic about letting us deal with him. She does best when her son, my husband, is there but he works so can only be there in the evenings.
