Science Stats “Alzheimer’s Advancing” (SN: 3/9/13, p. 4) reports a new analysis extrapolating from 2010 U.S. Census data that concludes Alzheimer’s disease will triple by 2050. Omitted in such an analysis is the accelerating advance of science and medicine over the next 40 years. The gloomy prediction makes little sense unless science stops short while the disease continues to progress.

Researchers are working hard on treatments for Alzheimer’s. But until they find ways to prevent the disease, more people will continue to be diagnosed. That trend is driven by the demographics of an aging population. —Erika Engelhaupt
