My MIL lives with us and I am her full time caretaker for over a year, and of course she gets upset with me for being what she calls bossy some times. (She has dementia) but the last couple of weeks she is fine during the day but around 4:30 or so she starts getting hateful and starts refusing her meds and her breathing treatments. When my husband gets home, around the same time she acts like I've been mean to her all day. He knows that's not true but then she gets worse as the night goes on. Now in the evening she is refusing to eat and complains that she feels sick, (She is on meds daily that is suppose to be taken with food.) The same meds she has been on for over a year. I usually just get mean and tell her if she doesn't eat, take meds, or what ever, that she is going to the hospital. Is this normal for dementia?
