Alzheimer's disease is the "epidemic of our century." That's the opinion of Nilufer Ertekin-Taner, a neurologist and neuroscientist with the Mayo Clinic in Jacksonville who is intimately involved in research on the disease. Ertekin-Taner was the lead investigator on a study, the results of which were published online recently in PLoS Genetics, in which she and her co-authors build the case that neurodegenerative diseases like Alzheimer's are primarily caused by genes that are either too active or not active enough, rather than by harmful gene mutations.
