Assessing the efficacy of antiepileptic treatments: the ketogenic diet

Abstract

Purpose: To evaluate the evidence for determining if the ketogenic diet is an effective treatment for epilepsy.

Methods: A literature review of published data over the past 80 years concerning the ketogenic diet was performed, focusing on efficacy, tolerability, age of patient population, as well as study design.

Results: There have been several studies involving prospective and retrospective studies showing the ketogenic diet to be a very efficacious treatment in epilepsy, particularly epilepsy in childhood. However, no Class 1 studies have been published concerning the efficacy of the ketogenic diet.

Conclusions: The ketogenic diet appears to be a very effective treatment for epilepsy, particularly in childhood. It would be beneficial to have Class 1 studies available to help better define the role of the diet both in children and adults.
