Well done, Hough! There is also a fairly strong statistical connection between high blood sugar and Alzheimer's. They are still investigating the mechanism, but it is suspected to involve an enzyme utilized in the brain to prevent the build up of the abnormal proteins characteristic of Alzheimer's which is degraded by excessive glycation (A1c (more properly hg A1c) is a measure of glycated hemoglobin)
This what happens when you don't see a doctor for 17 years....and then you have the full battery of tests run.
