Alzheimer's disease: Early signs and symptoms you may spot in yourself or a loved one

Fox News medical contributor Dr. Janette Nesheiwat joins'Fox News Live' to discuss the results of an Alzheimer's drug trial by Eli Lilly. Alzheimer's is a disease that heavily impacts memory function, typically in older people. Since memory loss commonly comes with aging, it can be hard to detect if a symptom is just one that comes with old age, or a sign of Alzheimer's disease. The main symptom of Alzheimer's disease is memory loss. More than that, it's memory loss that happens frequently and gets worse over time.
