Anemia linked to increased risk of dementia

Anemia may be one sign someone has an increased risk of developing dementia, according to a new study published in Neurology, the medical journal of the American Academy of Neurology.

“I’ve been studying Alzheimer’s for a long time,” says study author Dr. Kristine Yaffe, of the University of California – San Francisco. “In particular, I’m interested in things you can modify: cardiovascular disease, sleep, physical activity.
