Ketogenic diet in the treatment of refractory epilepsy in childhood

Abstract

There has been renewed interest in the ketogenic diet in the treatment of medically refractory seizure disorders in childhood. This article reports the results of a retrospective chart review of 52 patients who were treated with the ketogenic diet. The vast majority (49 of 52) were treated with the classic 4:1 diet. Seizure control improved in 67.3% of patients with complete abolition of seizures in six. Adverse reactions were uncommon and included the development of renal stones, gall bladder stones, and hypoproteinemia in one patient each. Routine biochemical screening during the diet did not identify or prevent adverse events. The authors' experiences with the diet emphasize the need for close ongoing medical and dietary supervision.
