My 85-year-old mother has been having memory 'gaps' and being very suspicious for approximately two years, but it has gotten much worse. Someone came into her house and 'stole' all her muffin pans and casserole dishes, women at church are 'out to get' her husband, my step-dad, and she pulls the drapes tightly closed at 4pm because she 'doesn't want people to know our business.' I had her internist give her a neurological test 12 months ago, 6 months ago, and yesterday. Her score is 22 out of 30. (worse than 12 months ago, but same as 6 months ago). She flatly refuses to take Aricept nor have an MRI. She becomes VERY defensive when we talk about her 'memory' and snapped that she would like me to find anyone else who is 85 who doesn't have the same problem. She states the only reason she 'forgets' is that she is stressed out. I have tried to remove all the stressors from her life that I can (i.e., hiring a lady to clean the house, finding out about grocery delivery, etc.,) but she continues to say that she only forgets if she gets rushed and stressed. She recently 'forgot' to pay her car insurance, and states that charges mysteriously appear on her credit card. However, she cannot 'find' the statements when I tell her that we can go over these. She also does not want to let me start paying her bills for her (my suggestion). Any ideas how to proceed here?
