Controlling your blood sugar is important whether or not you have diabetes. Elevated blood sugars contribute to heart, stroke, kidney, eye, nerve and other problems. While many doctors suspected that high blood sugars might cause changes in cognitive (brain) function, there were not strong research studies showing the link. In August 2013, the New England Journal of Medicine, published a study looking at a large group of people over a long period of time and found that there was an association between high blood sugar levels and development of dementia and Alzheimer’s Disease.
