My mother does not believe there is anything abnormal about her memory or behavior. To us children it's been a frustrating reality that dementia has taken a strong hold. But to her, its the aging process and we need to accept it. I had a talk with the doctor, who first mentioned it to us, and she finally ordered an MRI, which mom then refused to have done. How do you convince, or do you convince, a loved one that she has dementia and that it can be treated?
