High Blood Sugar Linked to Dementia
By PAULA SPAN
People with diabetes face an increased risk of Alzheimer’s disease and other forms of dementia, a connection scientists and physicians have worried about for years. They still can’t explain it.
Now comes a novel observational study of patients at a large health care system in Washington State showing that higher blood glucose levels are associated with a greater risk of dementia — even among people who don’t have diabetes. 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.
The researchers tracked the blood glucose levels of 2,067 members of Group Health, a nonprofit HMO, for nearly seven years on average. Some patients had Type 2 diabetes when the study began, but most didn’t. None had dementia.
Over the years, as they saw doctors at Group Health, the participants received blood glucose tests. “It’s a common test in routine clinical practice,” Dr. Crane said. “We had an amazing opportunity with all this data. All the lab results since 1988 were available to us.”
The participants (average age at the start: 76) also reported to Group Health every other year for cognitive screening and, if their results were below normal, further testing and evaluation. Over the course of the study, about a quarter developed dementia of some kind, primarily Alzheimer’s disease or vascular dementia.
