Blood Sugar and Dementia

by Berkeley Wellness  |  

Even if you don’t have diabetes, elevated blood sugar may increase the risk of dementia, suggested a study in the New England Journal of Medicine in August. Previous research has strongly linked type 2 diabetes to cognitive decline and dementia, especially when the disease is not treated adequately.

But the new study, which looked at more than 2,000 healthy people over 65, found that even those with average blood sugar levels of 115 (100 to 125 is considered prediabetes) were nearly 30 percent more likely to develop dementia than those with levels averaging 95.

This was an observational study, however, and doesn’t prove that elevated blood sugar causes dementia or that people who lower it reduce their dementia risk.
