Hi, I live in Hawaii and my sister in CA. She has just been started on Aricept, but her MD is telling her she doesn't have Alzheimer's...just normal brain shrinkage. Isn't Alzheimers only diagnosable from an atopsie? I and her children see evidence of real memory loss...keys lost, checks lost, can't deal with bills, phone or computer issues, can't make airline reservations, print boarding passes...things she could handle before. What is her MD really saying? She lives alone with no relatives close by, but strong support from friends. Thanks for the welcome and support Sally
