Ann Poehler’s strides quicken on the treadmill. Her feet pound. Her heart races from 150 to 160 beats per minute and more.

A national study, published online Monday in the journal JAMA Internal Medicine, offered positive signs on what has long been a bleak landscape. It showed that the rate of dementia in people 65 and older had decreased from 11.6 percent in 2000 to 8.8 percent in 2012 for reasons that, not fully understood, researchers are exploring.
