High Blood Sugar May Add to Alzheimer's Risk: Study

Elevated blood sugar levels may increase a person's risk for Alzheimer's disease, according to a new study. Previous research has suggested that diabetes may be a risk factor for Alzheimer's, but University of Arizona researchers wanted to examine if high blood sugar levels in people without diabetes may also increase the chances of developing Alzheimer's. The study included 124 people, aged 47 to 68, who were diabetes-free and had normal brain function, but did have a family history of Alzheimer's. The participants underwent scans that revealed metabolic activity in the brain. http://www.nlm.nih.gov/medlineplus/news/fullstory_136639.html
