My 70 year old mom was diagnosed with vascular dementia Oct. 2010. My father recently passed away and last month I moved her to the state I live in so we can be closer to each other. I took her to a new doctor, it was actually a team of doctors that specialize in geriatrics memory care. They did a two hour evaluation and said she passed the memory tests with flying colors. One of the doctors even said he could not diagnois her with dementia. He is looking into what he called delirium from a gall bladder surgery she had 3 years ago. Does that sound realistic? She really does have a lot of symptoms for dementia. We have the same conversations every day, she forgets plans we make, she can't remember paying a bill, I have taken over her finances completely. I catch her doing odd things like burning her checkbooks inside the home, going for a walk barefoot in the snow,. The worst thing with all this is she hears voices at night and she thinks the government is behind everything to drive her crazy or make her die. Any thoughts from anyone? I am at a loss.
