The hard part is over.
I'm matching you with one of our specialists who will be calling you in the next few minutes.
During the 6 months prior to my Mom's admission to the nursing home, she would threaten to call the police whenever we had an argument or when I wouldn't do what she what me to do.
That way if your Mom (as Ahmijoy stated) does become physically abusive towards you or the home health aides, the police will be forewarned and have a better idea how to handle the situation prior to arriving to your parent's house.
Ahmijoy also mentions the possibility of your Mother having a urinary tract infection (UTI). That does cause sudden behavior changes in the elderly and even though your Mom is only 61, her health is that of an 80 year old. Has your Mom ever had a UTI?
I take it, since you suggest Mom has gone through a few caregivers, she is rather difficult? Have you spoken with the caregiver and assured them that you trust them? While it’s no fun to be accused of being a thief, caregivers are used to dealing with difficult patients. However, if Mom takes it to another level and becomes combative and physical like my mom did, you may have to start planning for a facility, sorry to say. And this time she may need Memory Care a.k.a. The Alzheimer’s Unit. She may change her mind about being difficult if she knows the alternative. And, tnere’s always checking for the UTI as those infections can completely alter the behavior of senior citizens. After decking two nurses and gouging my arm, we had my mom tested every month.
