The ketogenic diet: additional information from a crossover study.

The purpose of this blinded, crossover study of the ketogenic diet in children with the Lennox-Gastaut syndrome was to confirm, by the addition of 60 g of glucose per day to negate the ketosis, that the effectiveness of the ketogenic diet was neither the result of a placebo effect nor due to parental expectations and commitment. We found that the additional glucose did not significantly alter the frequency of electroencephalography-assessed events, but did decrease the frequency of parent-reported "drop" seizures (P = .07). Fasting had substantial effects on both seizures and electroencephalography-assessed events. The diet remained effective in decreasing seizures of the Lennox-Gastaut syndrome at 12 days, 6 months, and 12 months. In conclusion, the ketogenic diet is effective in decreasing the drop seizures of the Lennox-Gastaut syndrome.
