(CNN) – The criteria for diagnosing Alzheimer’s disease have remained virtually unchanged since the early 1980’s. However, last week new guidelines were proposed that would lead to earlier diagnosis. Although this would mean better care for patients, it would also lead to a significant increase in the number of people diagnosed with the disease. Dr. Maria Carrillo, senior director of medical and scientific relations for the Alzheimer’s Association, joined us on Tuesday’s American Morning to discuss the proposed guidelines.
