Iatrogenic hypoglycemia is a limiting factor for managing diabetes mellitus and can have severe outcomes such as seizures and coma. Although several studies have investigated the central nervous system consequences of hypoglycemia, the effects of seizures, as well as possible treatment strategies, have yet to be elucidated in juvenile animals. The objective of this thesis was to establish an in vivo model of severe hypoglycemia and seizures in juvenile diabetic and non-diabetic rats. In both groups there existed a similar blood glucose threshold for seizures, and mortality only occurred following severe seizures, particularly with repeated seizures that were unresponsive to treatment. While the administration of anticonvulsants temporarily mitigated seizures, glucose administration was required to prevent mortality. Abnormalities in the hippocampal and brainstem electroencephalograms (EEG) were observed in hypoglycemic animals without a clear correlate to convulsive activity.
