My 93 yr old mother has been independent until about 3 yrs ago when she fell and broke her wrist and had fallen and broken her hip the year before. So she went to nursing home for a while till I brought her here to a very nice assisted living home. She is insisting she can live on her own -NOT... and has threatened to not pay this next month payment/rent and that she is leaving the place. I am at my wits end trying to deal with her. What do I do to make sure she doesn't leave this place - for one thing she uses a walker and can not get very far on her own. Can her mood changes be part of the on-come of dementia? Help! I can't even think straight any more. She is impossible.
