My mother is exhibiting signs of dementia or Alzheimer's. She refuses to recognize her forgetfulness, confusion always giving an excuse or explanation such as being tired or stressed. Her PC doctor has noticed and is referring her to a neurologist. What is the best way to 'break it to her' that she is going to be tested? I haven't told her yet; neither has the doctor. An added note: her sister, my aunt, passed away last March. She was diagnosed with Alzheimer's nine years ago.
