Mayo Clinic Study Identifies Earliest Stages of Alzheimer's Disease

Addressing the earliest stages of Alzheimer's disease, before a patient shows outward signs of cognitive problems, has sometimes been a challenge for physicians and researchers, in part because they have not been using common and specific terms to describe the disease's initial phases. A Mayo Clinic study recommends adding categories to more effectively identify and treat people and give researchers standard definitions to work with. The study is published in this month's issue of the Annals of Neurology.
