  • High Blood Sugar Linked to Dementia

    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.

    To measure blood sugar levels, the researchers combined glucose measurements, both fasting and nonfasting, with the HbA1c glycated hemoglobin assay, which provides a more accurate long-term picture. They also adjusted the data for other cardiovascular factors already linked to dementia, like high blood pressure and smoking.

    “We found a steadily increasing risk associated with ever-higher blood glucose levels, even in people who didn’t have diabetes,” Dr. Crane said. Of particular interest: “There’s no threshold, no place where the risk doesn’t go up any further or down any further.” The association with dementia kept climbing with higher blood sugar levels and, at the other end of the spectrum, continued to decrease with lower levels.

      My grandparents on my mother's side are always trying to prevent Alzheimer's, but in the wrong way. They believe that it's caused by aluminum, so they don't use any products with aluminum. No cans or antiperspirant. Meanwhile, instead of soda, they drink a "health tonic" made of mostly agave nectar with some water, lemon juice, and cayenne pepper, and they eat the most conventional meats and dairy they can find, atop an enormous bed of bread and potatoes. They're obese and likely have diabetes.

      I'd bet anything that if they get Alzheimer's they'll still be blaming aluminum instead of their diet.

        Sometimes I wish I didn't read things like this.
