Epilepsy is a neurological disorder characterized by recurrent seizures. While antiseizure medications and other treatment modalities are commonly used to manage epilepsy, some infants with drug-resistant epilepsy may not respond well to these conventional therapies. In recent years, there has been growing interest in exploring alternative approaches, such as the ketogenic diet, for the management of drug-resistant epilepsy in infants. This article delves into the effectiveness of a ketogenic diet as an alternative to antiseizure medications in infants with drug-resistant epilepsy.
Understanding Drug-Resistant Epilepsy in Infants
Drug-resistant epilepsy refers to a condition where seizures persist despite treatment with appropriate antiseizure medications. Infantile epilepsy, occurring within the first two years of life, presents unique challenges in terms of treatment and long-term neurological outcomes. Many infant epilepsies have a poor prognosis, making it crucial to explore alternative treatment options that can effectively reduce seizure frequency and improve developmental outcomes.
The Ketogenic Diet as a Non-Drug Therapy Option
The ketogenic diet is a high-fat, low-carbohydrate diet that has been successfully used to manage drug-resistant epilepsy in both pediatric and adult populations. This diet induces a state of ketosis, where the body utilizes ketones as an alternative energy source instead of glucose. Ketones are produced when the body breaks down fat, and they have been shown to have antiseizure effects. The ketogenic diet has gained attention as a non-drug therapy option for infants with drug-resistant epilepsy.

Study: Ketogenic Diet vs. Antiseizure Medications for Infants with Drug-Resistant Epilepsy
In a recent study published in The Lancet Neurology, researchers conducted a multicenter, open-label, randomized clinical trial to evaluate the effectiveness of a ketogenic diet compared to antiseizure medications in newborns with drug-resistant epilepsy. The study included infants aged below two years who had experienced at least four seizures per week that were unresponsive to previous pharmacological treatments.
The researchers randomized the infants into two groups: the ketogenic diet group and the antiseizure medication group. The primary outcome measure was the number of seizures per day from the sixth to the eighth week of treatment. Secondary outcomes included seizure reduction, food tolerability, and neurodevelopmental outcomes. The study also assessed treatment retention and quality of life at one year.
Results of the Clinical Trial
The study enrolled a total of 136 infants, with 78 assigned to the ketogenic diet group and 58 to the antiseizure medication group. During the sixth to eighth weeks of treatment, the median daily seizure count was comparable between the two groups. However, at eight weeks, a higher percentage of infants in the ketogenic diet group experienced a reduction of more than 50% in seizure frequency compared to the antiseizure medication group.
Interestingly, some infants in the ketogenic diet group became seizure-free, although the percentage was similar to that of the antiseizure medication group. At one year, there were no significant differences in seizure outcomes between the two groups, except for certain aspects of neurodevelopment and quality of life, which favored the antiseizure medication group.
Safety and Tolerability of the Ketogenic Diet
Both the ketogenic diet and antiseizure medications were generally well-tolerated by the infants in the study. However, a comparable percentage of infants in both groups experienced one or more significant adverse events, with seizures being the most common adverse event. While there were three fatalities among the infants in the ketogenic diet group, these were determined to be unrelated to the therapy.
Implications and Future Research
The results of this study suggest that the ketogenic diet can be a safe and effective alternative to antiseizure medications for infants with drug-resistant epilepsy. It provides a non-drug therapy option that may improve seizure control and enhance quality of life and neurodevelopmental outcomes. However, further cohort studies and different study designs are needed to fully understand the benefits and risks of the ketogenic diet in this population.
Conclusion
Managing drug-resistant epilepsy in infants is a complex challenge that requires exploring alternative treatment options. The ketogenic diet has emerged as a promising non-drug therapy option for infants with drug-resistant epilepsy. The recent clinical trial discussed in this article provides evidence of the effectiveness and tolerability of the ketogenic diet compared to antiseizure medications. While more research is needed, these findings offer hope for improving seizure control and overall outcomes in infants with drug-resistant epilepsy.
