Neonatal hypoglycemia can range from an asymptomatic state with a minimal EEG correlation to late-onset, idiopathic hypoglycemia accompanied by neurological symptoms and seizures. Toxemia and maternal diabetes are often encountered in high-risk pregnancies. These newborns usually present with decreased QS with a relative increase in AS. Transient hypocalcemia is often associated with barely abnormal interictal EEG and variable focal seizures (in 20% of patients). Convulsive patterns of hypomagnesemia, iatrogenic hypernatremia, and pyridoxine deficiency are described in EEG in Neonatal Seizures.
