My mum was recently diagnosed with dementia but has not accepted it. She thinks she is perfectly fine and that myself and family members are making her out to be crazy. She has accused a few of us of stealing from her and is convinced that I am poisoning her. I have tried to reason with her but due to covid 19 it has given her the perfect excuse not to have any of us in her house. Even though things are still going a miss she still thinks it's not down to her moving them but that they were obviously taken at an earlier date. Note sure what to do or say to make her understand that her memory is causing problems. Would appreciate any advice on how to handle this. Thank you for your time x
