Ketogenic Diet Therapy in Drug-Resistant Epilepsy: Clinical Rationale, Syndrome Indications, and Measurable Outcomes

Up to 40% of people with epilepsy do not achieve adequate seizure control with anti-seizure medications. For this population, ketogenic diet therapy offers a guideline-recommended, evidence-based alternative with a clinical profile that extends beyond seizure frequency to cognition, behaviour, and daily functioning.

This hub covers expert clinical perspectives on ketogenic diet therapy in complex epilepsy, its application across specific paediatric syndromes, and quantified outcome data on seizure control, cognitive function, and quality of life.

Ketogenic diet therapy is not a uniform intervention. Its application, tolerability, and efficacy profile vary across paediatric epilepsy syndromes including infantile spasms, Dravet syndrome, and Angelman syndrome, each presenting distinct clinical challenges that influence dietary management decisions.

Expert clinical perspectives from international ketogenic diet specialists examine how KDT performs across these complex presentations, where it delivers meaningful seizure reduction, and what clinical considerations guide implementation across diverse syndrome profiles. This collection bridges the gap between guideline recommendations and real-world specialist practice.

Drug-resistant epilepsy is defined by failure to achieve sustained seizure control following adequate trials of two or more tolerated anti-seizure medications. In paediatric populations, uncontrolled seizures carry compounding consequences including long-term cognitive decline, impaired psychomotor development, and significant family burden.

For patients where surgery and neurostimulation are not appropriate, ketogenic diet therapy provides a clinically validated pathway. International guidelines recommend its consideration after failure of two to three drugs, with demonstrated efficacy across syndromes including infantile spasms, Dravet syndrome, and Angelman syndrome.

Up to 28% of children with drug-resistant epilepsy achieve seizure freedom on ketogenic diet therapy, while up to 60% experience a greater than 50% reduction in seizure frequency. Beyond seizure control, documented benefits include improvements in sleep quality, cognitive function, and behaviour, outcomes that carry significant weight in long-term paediatric care planning.

These findings, presented alongside guideline-recommended thresholds for initiating KDT, provide the evidence base needed to support referral decisions, family discussions, and formulary considerations for dietary intervention in this population.
