The Hitchhiker's Guide to the Role of (Transient) Hypoglycemia in Refractory Seizures and Epilepsy

Hypoglycemia and hypoglycorrhachia, although they are uncommon causes of refractory seizures and epilepsy, should always be considered because they are potentially treatable conditions. A high index of suspicion and low threshold for testing recurrent blood and at least one cerebrospinal fluid glucose level are required. Jeavons syndrome and other refractory cryptogenic/idiopathic epilepsies may involve symptomatic etiologies, including hyperinsulinism, GLUT1 deficiency, and other metabolic disorders.
