Ketogenic diet for Epilepsy

Ketogenic diet therapies have proven efficacy for refractory epilepsy. In this study, the authors observed remarkable efficacy of the diet in two patients with hypoxic-ischaemic encephalopathy (1). They analysed their cases with refractory structural epilepsies of acquired origin to characterize their response to the ketogenic diet. The classical ketogenic diet was implemented with dietary ratios of 3:1 to 4.4:1. Seizure frequency at 1 month, 3 months, 6 months, 1 year, and 2 years was ascertained. A responder was defined as greater than 50% seizure reduction compared to baseline. The results showed that the ketogenic diet was effective in patients with a developmental and epileptic encephalopathy due to an acquired structural aetiology. This cohort may not be routinely considered for the ketogenic diet because of their structural and acquired, rather than genetic, basis. The authors conclude that the ketogenic diet should be considered early in the management of patients with acquired structural encephalopathies as it can improve seizure control with the potential to improve developmental outcome.
