My husband with dementia is now cannot maintain his balance. Very unsteady on his feet. Now has trouble going out even with a walker. What comes next. Home health is suppose to be helping with balance but seems not to help. Went from very aggressive and talkative to submissive. Staying in bed alot and stays very cold. Doctors just had to double his high blood pressure and add another to keep his blood pressure down. Appetite is not good at all. I know its getting worse, but want some advise. Thanks.
