My sister has some form of dementia/alzheimers and wants to know if there is anyway to find out what area of her brain is affected by the disease? Before we knew she was ill she complained of pain of the left side of her head. At first I thought she had a stroke, but there were no signs when she saw the neurologist. She felt that if she knew which area was affected she might be able to focus on activities that used the healthier part of her brain. Also, she wants publications about the disease so she can know what is happening to her. Most publications seem to deal with the disease from the care-givers view and are pretty dismal. Would it be better to distract her with other publications?
