Verbal intelligence reduced with increased exposure to hyperglycemia, not hypoglycemia

In this original research involving school aged youth aged 5-16 years old, the group with Type 1 Diabetes had lower estimated verbal intelligence compared to unaffected  siblings. Within Type 1  group, verbal intelligence was reduced with increased exposure to Hyper, not to Hypo. In contrast, spatial intelligence and delayed recall were reduced only with repeated Hypoglycemia

Conclusions: Hypo and Hyper have qualitatively different effects on cognitive function in T1DM that depend in part on the timing of exposure during development, independent of onset 
age. This information extends the known benefits of avoiding both Hypo and chronic Hyper during childhood to include preservation of specific cognitive skills.
