Dementia Risk

High blood sugar levels seem to dramatically increase the risk of dementia. Researchers studied patients with type 2 diabetes to determine if elevated glycosylated hemoglobin, a marker of blood sugar control, correlated with increased dementia risk. Compared with those with normal levels (less than seven), those with levels greater than 12 were 22% more likely to develop dementia. Those with levels greater than 15 were 78% more likely to get dementia.
