High blood sugar levels can be linked to heart disease, cognitive issues and even fertility problems. High blood sugar levels are also commonly associated with an increased risk of developing diabetes. However, even without a diabetes diagnosis, high blood sugar levels can still have a dramatic impact on your health and well-being.
First author of the study, Dr. Paul Crane, of the University of Washington stated that “the most interesting finding was that every incrementally higher glucose level was associated with a higher risk of dementia in people who did not have diabetes.”
The study found that “in people without diabetes, risk for dementia was 18 per cent higher for people with an average glucose level of 115 milligrams per decilitre compared to those with an average glucose level of 100mg/dl. And in people with diabetes, whose blood sugar levels are generally higher, dementia risk was 40 percent higher for people with an average glucose level of 190 mg/dl, compared to those with an average glucose level of 160 mg/dl.”
Researchers analyzed more than 2,000 people aged 65 and older who were part of the Adult Changes in Thought study, which began in 1994. Measurements for the study include blood glucose and glycated hemoglobin.
While the findings are promising, Crane stresses that the results are coming from an observational study, stating that, “what we found was that people with higher levels of glucose had a higher risk of dementia, on average, than did people with lower levels of glucose. He concluded by stating that “while this is interesting and important, we have no data to suggest that people who make changes to lower their glucose improve their dementia risk. Those data would have to come from future studies with different study [design].”
