Physical Activity, Ketogenic Diet, and Epilepsy: A Mini-Review

Abstract

One-third of patients with epilepsy do not respond to antiepileptic drugs and may seek complementary and alternative treatment modalities. Dietary therapies, such as the ketogenic diet (KD), the modified Atkins diet, as well as the medium-chain triglyceride and the low glycaemic index diets, have been successfully implemented with some forms of epilepsy and are growing in utilization. The KD is a high-fat, low-protein, low-carbohydrate diet that has been used for various conditions for over a century. Insights into the mechanism of action of these diets may provide more targeted interventions for patients with epilepsy. Knowledge of these mechanisms is growing and includes neuroprotective effects on oxidative stress, neuroinflammation, potassium channels in the brain, and mitochondrial function. In this review, we explain the role of physical exercise and the ketogenic diet on epilepsy.
