My husband and I are caring for his Mother who recently lost her husband. A few years ago she suffered a stroke that increased her diminishing memory issues. She is 90 years old and doesn't remember the stroke. Further when she forgets things she calls whoever remembers the facts liars, at a tantrum level. Since her husband passed she creates horrible stories about family members, including her deceased husband to garner attention. She calls anyone who will take her calls repeatedly to spread these falsehoods. This makes most days almost unbearable. Currently we have her at our home for a week (celebrating her birthday). The first day she went into the laundry room, urinated, then closed the door leaving the huge puddle. She denied it (as usual). I am beginning to believe that the severe dementia has escalated into Alzheimer's due to the meanness of her actions and comments. Is there a test than I can have done to determine what the real issue may be ? My husband's siblings are not and never have been willing to care for her. I will continue to care for her regardless of her issues, but it is becoming very difficult and the insults are starting affect me. Her husband was very aware of this problem, but he kept quiet for the sake of his own sanity. Any suggestions are most welcome.
