Doctors told us that my mom is in the early stage of dementia. she got really upset with the doctor and changed the doctor. She forgets that she asked me to pay certain bills then she question me and say why did I do that and I should have asked her about it. I even asked her to sign a paper when she asked me to give some money to my sister just for my protection, when she questioned me I showed her the signed paper then she said that is not her signature. I am starting to think I need to record our conversations from now on. I really don't know what else to do. Any ideas?
