Ketogenic diet therapy for epilepsy: Clinical pearls

Area of Science:

• Neurology
• Clinical Nutrition
• Epileptology

Background:

• Drug-resistant epilepsy presents a significant clinical challenge, often necessitating alternative therapeutic strategies.
• Ketogenic diet therapy (KDT) is a well-established, non-pharmacological treatment option for epilepsy.
• Early intervention with KDT can mitigate seizure burden and reduce reliance on long-term polytherapy.

Purpose of the Study:

• To provide practical insights and actionable knowledge for healthcare professionals new to implementing KDT in clinical practice.
• To review the different types of KDT, including classic KDT, modified Atkins diet, medium-chain triglyceride ketogenic diet, and low glycemic index treatment.
• To guide the identification of suitable candidates and outline contraindications for KDT in epilepsy management.

Main Methods:

• A comprehensive review of current literature and clinical experience from three level three epilepsy centers.
• Focus on practical application, including patient selection criteria, contraindications, and management of special settings.
• Emphasis on addressing common side effects and abnormal laboratory results associated with KDT.

Main Results:

• KDT, encompassing various formulations, is a rapidly implementable and effective treatment for drug-resistant epilepsy.
• Identifying 'good responders' is crucial for optimizing KDT outcomes and minimizing treatment burden.
• Specific metabolic disorders and adherence concerns represent contraindications or require caution during KDT.

Conclusions:

• Early and appropriate application of KDT can significantly improve seizure control in patients with drug-resistant epilepsy.
• Understanding patient selection, contraindications, and potential side effects is essential for successful KDT implementation.
• This review equips early-career professionals with the necessary knowledge for confident and effective clinical use of KDT.
