The ketogenic diet--update on recent clinical trials

Area of Science:

• Neurology
• Dietary Therapies
• Epilepsy Management

Background:

• The ketogenic diet (KD) has a century-long history in epilepsy treatment.
• Its use declined with anticonvulsant medications but has resurged in the last 15 years.
• Limited resources and availability, particularly for pediatric patients, remain significant challenges.

Purpose of the Study:

• To evaluate the efficacy of the KD in epilepsy treatment.
• To address the historical lack of high-quality trial data for the KD.
• To compare the KD's effectiveness against contemporary anticonvulsant therapies.

Main Methods:

• Review of existing cohort studies and systematic reviews.
• Analysis of data, noting limitations to Class 3 and 4 evidence.
• Inclusion of a recent randomized controlled trial (RCT) comparing KD to anticonvulsant drugs.

Main Results:

• The KD demonstrates significant benefits in epilepsy management.
• Previous studies were limited in design quality (Class 3 and 4).
• A recent RCT shows KD efficacy is equivalent to new anticonvulsant medications.

Conclusions:

• The ketogenic diet is a viable and effective treatment for epilepsy.
• High-quality evidence now supports the KD's comparable efficacy to modern drugs.
• Increased resources are crucial to improve the availability and accessibility of the KD for patients.
