My mother was diagnosed with Alzheimer's early this year. When I told her she wouldn't believe and began worrying even more which I believe is not good for dementia patients. So I told her the diagnosis is still not confirmed. She is kind of balanced thereafter. But I know as her disease progresses she will not be able to think enough and while now the disease is in early stages I would like her to take some decisions about her future. Any thoughts how to handle this?
