Epilepsia

The ketogenic diet (KD) is a high-fat, low-carbohydrate and -protein diet that has been used to treat refractory seizures in children for more than 75 years. However, little is known about how the KD inhibits seizures or its effects on epileptogenesis. Several animal models of epilepsy have responded favorably to KD treatment, but the KD has not been studied in animals with a genetic predisposition to seizures. Here we studied the antiepileptogenic effect of the KD in EL mice, an animal model for human idiopathic epilepsy. ⋯ The KD delayed seizure onset in EL mice, suggesting a transient protection against epileptogenesis. The KD did not influence plasma glucose levels or associative learning. Therefore, the EL mouse may serve as a good model to study the antiepileptogenic mechanisms of the KD.
