High Blood Sugar Linked to Dementia

Higher blood glucose levels are associated with a greater risk of dementia – even among people who don’t have diabetes. Researchers tracked the blood glucose levels of 2,067 members of Group Health, for nearly seven years on average. Some patients had Type 2 diabetes when the study began, but most didn’t. None had dementia.

The results, published Thursday in The New England Journal of Medicine, “may have influence on the way we think about blood sugar and the brain,” said Dr. Paul Crane, the lead author and associate professor of medicine at the University of Washington.
