My mom died 3 years ago. I have 1 sister but she doesn't have a relationship with our dad. I talk to my dad every week for an hour and a half (usually the same conversations over and over). I am all he has. I have known for several years that he has symptoms of dementia, but I just go along with whatever he says. Today, for the first time, he has turned against me. He said I visited him 2 weeks ago and stole his tax returns. He also said it appeared I was on narcotics. The last time I was really there was in December. I have been planning to visit him next week, to go to the tax preparer and also to help him with his bank account. He claims that he has no money and his social security and retirement pay aren't going into his bank account. I was on the phone with his bank and him 3-4 weeks ago to go over his account and the money is going in, but he doesn't believe it. So today when we talked on the phone, he turned on me for the first time. He said I was there 2 weeks ago and took his tax returns. I kept saying I wasn't there, and he is convinced I was. He got very angry, told me not to come next week and hung up. I don't know what to do next!!! Help!!
