A search through PubMed yields plenty of articles referencing Alzheimer's Disease as "Type 3 Diabetes." The intricacies of the relationships among everything involved in diabetes and dementia are well beyond my capacities and, being beyond me, create shadows where all sorts of fears may thrive.

Looking back at the results of some of my own recent-ish tests, a fasting blood glucose level of 90 is still firmly in the "normal" range -- understanding the ranges are not set in stone. On the other hand, some make an excellent case that anyone eating a modern diet is "very close to pre-diabetes" or at least more susceptible to developing insulin resistance than standard clinical practice recognizes.
Gosh. I wish I could get there.
