A new study published in the New England Journal of Medicine found that high blood sugar levels were associated with an increased incident of dementia. Over 2,000 men and women over the age of 65 were studied for 6-8 years. Those participants that had a blood glucose of 115, compared to 100, had a 15% increased risk of developing dementia. Prior studies done revealed that those with diabetes had an increased incidence, yet this study shows that non-diabetics with elevated glucose levels are at a higher risk as well.
