The sleep electroencephalogram (EEG) of patient #3 is illustrated. (a) EEG recorded before starting the ketogenic diet (KD). Note that a lack of spike and wave activities in the centroposterior areas is indicated by asterisks. Slow and sharp waves are frequently recorded from frontal regions (arrowheads), with a tendency to generalize and synchronize in bursts. (b) EEG obtained under treatment with the KD. Note that subcontinuous high-voltage sharp-waves are present (arrowhead), and that short ictal activity, which corresponded to minimal clinical expression (staring with slow rhythmic eye movements), is also detectable. EEG recordings were made by a 12 channel system (Galileo NT Suite Software). Images are presented on longitudinal reading montages. Amplitude, 20 µV/mm.
