I'm caring for Mom (85) suffers from dementia (mild). She will not accept the fact that she no longer is able to look after herself. Talking calmly, and being honest, rational and letting her know that she has family and a daughter that love and want to have her in our lives works for a while, until she has a 'spat' and demands to be 'taken' to her home 3 hrs away, and left there on her own, because she wanto to stay at home.. She maintains her strong desire to 'stay' on her own at all costs. She has had heart surgery, 2 knee replacements, has fallen 2 times. (when left on her own over 3yrs ago). Im wondering about whether some form of medication can pacify her. Advice ??
