Is it Alzheimer's disease?

According to one estimate, Alzheimer's disease has been diagnosed in more than 4 million Americans. As our population continues to age, we can expect to see a sharp increase in this number. By the middle of the next century, there are projected to be almost as many Americans over age 80 as there now are over age 65. Primary care physicians are bound to see more and more patients who appear to have Alzheimer's disease, and the burden is on them to rule out other, treatable forms of dementia. Dr. Gambert describes how to distinguish the true cognitive dysfunction of Alzheimer's disease and where to go from there.
