Findings

Lancet Neurology 2026 update on ketogenic diet therapy in pediatric epilepsy. Reviews mechanisms (including BHB-mediated E/I modulation), indications, response rates across DEE subtypes, and practical implementation.

Why it may matter for Levi

Ketogenic diet is in Levi's treatments workspace as a mid-tier option. This 2026 update strengthens the evidence base but does not change rank. Useful as a current synthesis reference if KD discussion becomes active.

Why in corpus

Highest-impact 2026 synthesis on ketogenic-diet therapy in epilepsy. Complements Qiao 2024 (β-HB mechanism) already in the corpus.

Key findings

  • Ketogenic-diet therapies exert antiseizure effects independent of seizure type or cause.
  • Mechanisms include metabolic shift to ketone bodies, neurotransmitter modulation, and anti-inflammatory effects.
  • Children with epilepsy on ketogenic diet show ~6× greater likelihood of achieving seizure reduction compared to controls.
  • Early initiation, particularly in metabolic epilepsies, improves seizure outcomes.

Levi-relevant takeaways

  • Keeps ketogenic diet as a viable second-tier option for Levi if corticosteroid durability is limited.
  • The 6× response-rate figure is a compelling quantitative anchor for family-facing discussion of the option.
  • Anti-inflammatory mechanism is mechanistically complementary to Levi's Th1/Th17 cytokine profile — ketogenic may indirectly dampen neuroinflammation, an under-appreciated benefit beyond pure antiseizure effect.
  • Adherence burden is substantial (family, feeding, school); worth discussing practicality with Jake and Miki and the Stanford feeding/nutrition team before activating.
