Vitamin D and Dementia
Older adults who are severelyvitamin D deficient have a 122 percent increased risk of developing Alzheimer’s, according to a new study published in the journal Neurology.
The research team, lead by Dr. David Llewellyn at the University of Exeter Medical School, anticipated a link between vitamin D deficiency and cognitive problems (previous research has shown a general correlation). But they were surprised by how high the risk was. “The association was twice as strong as we anticipated,” Llewellyn says.
