Normoglycaemic Neuroglycopenia Normoglycaemic neuroglycopenia, which can be produced experimentally by 2-dexoyglucose and other substances that impair intraneural glucose metabolism, may be more common than was once thought. It occurs in children (and possibly in adults) during certain viral infections of the central nervous system which interfere with glucose transport into the brain, and also possibly as an inherited abnormality and in diabetes.
