DEAR DOCTOR K: My mother has been diagnosed with Alzheimer's disease. Can you tell me about medications that are available to treat this disease? What can and can't they do?
DEAR READER: Alzheimer's disease is a form of dementia. It often affects short-term memory early on. It then progresses to impair other cognitive functions such as thinking and judgment. As the disease advances, it can affect a person's mood and behavior. Eventually, most people lose their ability to do normal daily activities.
