Epilepsia partialis continua (EPC) may occur during nonketotic hyperglycemi
a but has not been described with diabetic ketoacidosis. The authors report
a patient with EPC associated with ketotic hyperglycemia. Brain MRI showed
two areas of abnormal signal intensity in the left precentral gyrus and in
the right cerebellar hemisphere. Hyperglycemia may reduce seizure threshol
d because of the increase in gamma -aminobutyric acid metabolism and may tr
igger epileptic discharges.
