Insights
The ketogenic diet (KD) effectively reduced seizures in young Indian children with refractory epilepsy. This treatment was well-tolerated, though medical supervision is essential for managing side effects.
Area of Science:
- Pediatric Neurology
- Metabolic Therapies
- Epilepsy Management
Background:
- Refractory epilepsy poses significant challenges in pediatric populations.
- The ketogenic diet (KD) is an established alternative therapy for drug-resistant epilepsy.
Purpose of the Study:
- To assess the efficacy and tolerability of the KD in young Indian children with refractory epilepsy.
- To evaluate biochemical and lipid profile changes associated with KD therapy.
Main Methods:
- Enrolled children aged 6 months to 5 years with daily or near-daily seizures despite antiepileptic drug treatment.
- Implemented a non-fasting gradual initiation protocol for KD.
- Monitored seizure frequency, biochemical parameters, and adverse effects over a minimum of 12 months.
Main Results:
- 48% of children experienced over 50% seizure reduction, with 15% seizure-free at 6 months.
- At 1 year, 37% showed over 50% seizure reduction, and 18.5% were seizure-free.
- Common adverse effects included constipation (74%), weight loss (14.8%), with notable biochemical changes like reduced serum albumin and increased urinary calcium-creatinine ratio.
Conclusions:
- The ketogenic diet is a viable and effective treatment for refractory epilepsy in young Indian children.
- Careful medical supervision is crucial to manage adverse effects and ensure treatment safety.
Aim:
This study evaluated the efficacy and tolerability of the ketogenic diet (KD) in young Indian children with refractory epilepsy. The changes in biochemical and lipid profile with KD were also assessed.
Methods:
Children aged 6 months to 5 years who had daily seizures (or at least 7 seizures/week) despite the appropriate use of at least three antiepileptic drugs were enrolled. KD was introduced using a non-fasting gradual initiation protocol. Seizure frequency, biochemical profile (liver and kidney function tests, fasting lipid profile, and spot urinary calcium-creatinine ratio) and adverse effects were recorded. Patients continuing KD were followed up for a minimum period of 12 months.
Results:
Twenty-seven children were enrolled. Non-fasting gradual KD initiation was well tolerated. Eighty-eight percent remained on KD at 3 months, 55% remained on KD at 6 months, and 37% remained on it at 1 year. Intention-to-treat analysis revealed that 48% (13 of 27) had >50% reduction in seizures, and four children (15 %) were seizure free at 6 months. At 1 year, 37% had >50% reduction in seizures and five children (18.5%) were seizure free. Adverse effects included constipation (74%), weight loss (14.8%), edema due to hypo-albuminemia (7.4%) and renal stones (3.7%). Biochemical profile did not reveal significant changes over time, except for reduced serum albumin and increased spot urinary calcium-creatinine ratio.
Conclusion:
KD is an effective and well-tolerated treatment option in young Indian children with refractory epilepsy. However, careful ongoing medical supervision is needed.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
