The brain takes glucose as its sole energy source. No insulin, no glucose, brain death.

Interesting. I've been told repeatedly by nutritionists at endocrine clinics that, unlike all other organs and muscles, the brain requires no insulin to process glucose. Which is why excessive insulin and the low glucose it produces in type 1 is so much more dangerous in the short term than a lack of insulin and high glucose.

Excessive insulin induces all other regions of the body to consume all available glucose starving the brain, and possibly causing a black out. High blood sugar, caused by a lack of insulin (especially in an undiagnosed patient) has no practical effect on the brain in the short term, because the brain needs no insulin to process glucose.

Dang, I feel dumb tonight.

You’re right about brain cells not needing insulin.

Oh well, I’m at least two facts smarter than I was a little while ago. ;)
